Page 19: Installation Procedure
Chapter 3: Mechanical Installation 3.4 Installation Procedure The Canvas 7 utilizes a clip installation method to ensure a robust and watertight seal to the enclosure. Please follow the steps below for the proper installation and operation of the unit. This equipment is suitable for Class I, Division 2, Groups A, B, C and D or non-hazardous locations only. Digital outputs shall be supplied from the same source as the operator control station. Jumpers on connector JP1 shall not be removed or replaced while the circuit is live unless the area is known to be free of ignitable concentrations of flammable gases or vapors. 1. Carefully locate an appropriate place to mount the Canvas 7. Be sure to leave enough room at the top of the unit for insertion and removal of the microSD™ card. 2. Carefully cut the host panel per the diagram, creating a 131.9mm x 175.0mm, with a +1mm/-0mm panel cutout tolerance, opening into which the Canvas 7 may be installed. If the opening is too large, water may leak into the enclosure, potentially damaging the unit. If the opening is too small, the OCS may not fit through the hole without damage. 3. Remove any burrs and or sharp edges and ensure the panel is not warped in the cutting process. 4. Remove all Removable Terminals from the Canvas 7. Insert the Canvas 7 through the panel cutout (from the front). The gasket must be between the host panel and the Canvas 7. 5. Install and tighten the four mounting clips (provided in the box) until the gasket forms a tight seal. NOTE: Recommended torque is 7 to 10 in•lbs (0.8 - 1.13 N•m). 6. Reinstall the Canvas 7 I/O Removable Terminal Blocks. Connect communications cables to the serial port, USB ports, Ethernet port, and CAN port as required. Page 19 of 206...

Page 44 Chapter 5: System Settings To Set Time Zone: The Time Zone setting is an hourly offset from UTC time. If using the Time Zone setting, set it first, then set the local time. UTC time will be automatically set based on the time zone and local time settings. If using NTP: NTP utilizes UTC time, therefore when using NTP, the appropriate hourly offset from UTC time must entered into the time zone setting. Daylight Saving Time: If currently observing Daylight Saving Time, set to Yes. If not currently observing Daylight Saving Time, set to No. The OCS controller does not automatically switch to daylight saving time; however, program logic can be written to accomplish an automatic switchover using system register %SR211. In program logic, move a “1” (INT) into %SR211 to enable Daylight Saving Time. Move a “0” (INT) into %SR211 to disable Daylight Saving Time. Trigger the move to %SR211 based on a compare function to the RTC date according to daylight saving practices in your desired region. To Set Local Time: The Set Time/Date sub-menu displays three system settings. Time and Date may be edited, and Day is automatically calculated from the Date setting. NOTE: Time and Date are split into three fields each, all of them are editable. Toggle the edit enable buttons of Local Time / Local Date to edit all these three fields.

Chapter 7: Cscape Configuration Chapter 7: Cscape Configuration 7.1 Cscape Status Bar 7.2 Establishing Communications 7.3 Cscape Configuration Canvas 7 OCS hardware is programmed with a Windows based PC application called Cscape. This application can be used to program, configure, monitor, and debug all aspects of the Canvas 7 OCS unit. Please see the Online Help provided with Cscape for additional details. 7.1 Cscape Status Bar When the Canvas 7 OCS is connected to a PC using Cscape software, a Status Bar appears at the bottom of the screen. The Cscape Status Bar can be used to determine if communications have been established between the Canvas 7 OCS and the Cscape program. Components of the Cscape Status Bar are explained below: Page 68 of 206...
Page 69: Establishing Communications
Chapter 7: Cscape Configuration 7.2 Establishing Communications The Canvas 7 OCS can communicate with Cscape using USB to USB, USB to serial adapters, serial port communications via MJ1 Port, Ethernet (with an Ethernet adapter board), onboard Ethernet Port, CAN (CsCAN), or modems. If a direct USB connection is to be used, connect the Mini-USB port on the OCS (only on select models) to an open USB port on the PC. (A cable for doing this is included in HE-CPK, the programming kits.) The OCS will install as a device once plugged in. Drivers for it are normally found automatically by the Windows operating system as long as an Internet connection is established. See also the Tools of the Trade on the Horner website. The PC will detect a new device has been plugged into the USB port. Now that the Canvas 7 is plugged in, go to Cscape > Controller > Connection Wizard. If you are just opening Cscape, Connection Wizard usually opens by default. Select USB and click Next >>. ...
Page 70 Chapter 7: Cscape Configuration If the Connection Wizard does not pop up upon opening Cscape, then select Controller (in the Cscape tool bar) > Connection Wizard, choose your connection method. If you are connecting for the first time, we suggest connecting via USB. If Controller USB COM Port is not present in the dropdown list, the Windows operating system has not yet recognized the OCS as an installed device. Be sure the installation process is complete and that the correct drivers are installed. The Connection Wizard must be completely closed and reopened to refresh the USB dropdown list. An alternate way to select the COM setting is to go to Cscape > Tools > Application Settings > Communication > Configure and choose connection method in Add Target. Page 70 of 206...

Chapter 7: Cscape Configuration If communications are successful, the message line should show “USB (COM8)” for this example, and an (R) should follow the Target number. If the controller is not communicating, you may need to set the target ID of the controller in Cscape or on the unit. The Target ID allows directing communications to a particular unit when multiple units are connected via a CsCAN network. Units without CsCAN network ports respond to any network ID and do not require the ID to be configured. To check or change the ID on the Canvas 7 OCS, press the System Menu key. The first item in the menu is Set Networks. Pressing Enter allows you to view or modify the ID of the unit. To change the Target ID of Cscape, highlight CAN ID and press Enter t o provide a new number. 7.2.1 Communicating via MJ1 Serial Port If a serial programming connection is to be used and the PC has a 9-pin serial COM port, which is increasingly rare, there is nothing to install assuming the port already works. All that is needed is a programming cable to go from the COM port to the OCS programming port. Page 73 of 206...
Page 74 Chapter 7: Cscape Configuration If a serial programming connection is to be used and the PC does not have a COM port, a USB-to-Serial adapter may be used. Drivers for it are normally found automatically by the Windows operating system as long as an internet connection is established. Otherwise, the drivers may be loaded from the Horner FTP site at https://hornerautomation.com/support-files. Connect the PC’s serial port or the USB-to-Serial adaptor to the port labeled MJ1 on the Canvas 7. The instructions are similar to using a USB port, as shown above. In the Connection Wizard, select the “Serial” option. If communications are successful, the target indicator should show the mode of the controller Target: yy(R) as shown in the "7.1 Cscape Status Bar" on page 68. If the controller is not communicating, you may need to set the Target ID of the controller in Cscape or on the unit.

8.2 Removing the Back Cover WARNING: Power, including I/O power must be removed from the unit prior to removing the back cover. Failure to do so could result in electrocution and/or damage to equipment. Some I/O configurations require jumper settings to be changed inside the Horner OCS unit. Examples of these settings are setting positive or negative logic on digital inputs or setting current or voltage on analog inputs. Each Horner OCS I/O jumper is set to a factory default. Refer to the datasheet for a specific Horner OCS model to find the default setting to determine if a jumper change is necessary. Refer to Horner's Documentation Search page.

Page 81: Digital / Hsc Input Configuration
Chapter 8: General I/O Configuration 8.3 Digital / HSC Input Configuration Horner controllers vary greatly on series and model numbers. Refer to the datasheets on the Document Search table on the Horner website. The inputs are designed to support both positive and negative input modes. For many models, the mode is set by a jumper setting and a configuration parameter in Cscape. The Model 6 does not require jumpers, and only requires a configuration parameter in Cscape. All the inputs on the unit must be configured to the same mode. In positive logic mode a positive voltage applied to the input will turn the input. The internal design of this mode is basically a resistor from the input to I/O ground. This mode is sometimes called sourcing. In negative logic mode, connecting the input to the I/O ground or zero volts will turn the input on. The internal design of this mode is basically a resistor from the input to the positive I/O voltage (usually 12 or 24V). This mode is sometimes called sinking. Some of the digital inputs may support high-speed input functional such as counting or frequency measurement. Page 81 of 206...

Page 85: Digital / Pwm Output Configuration
Chapter 8: General I/O Configuration 8.4 Digital / PWM Output Configuration 8.4.1 Solid State Digital Outputs Solid-state digital outputs are generally used to activate lamps, low voltage solenoids, relays, and other low voltage and low current devices. NOTE: The digital outputs used on some controllers are sourcing outputs. This means the output applies a positive voltage to the output pin when turned ON. When turned off, the output applies approximately zero volts with respect to the I/O ground. Use the Documentation Page t o view the datasheet for a specific controller for specifics on a module's I/O. The digital outputs used in the OCS have electronic short circuit protection and current limiting. While these electronic protections work in most applications, some application may require external fusing on these outputs. The digital outputs in the OCS are typically controlled via %Q bits in the register mapping. Some of the outputs are designed for high-speed applications and can be used for PWM or frequency output applications. When the controller is stopped, the operation of each output is configurable. The outputs can hold the state they were in before the controller stopped or they can go to a predetermined state. By default, digital outputs turn off. NOTE: The digital outputs feature an output fault bit. %I32 will turn on if any of the outputs experience a short circuit, over-current or the output driver overheats. Page 85 of 206...
Page 86: Relay Outputs
Relay Life – Relays are mechanical devices that have a long but limited life. Typically, switching more current limits the life of relays. Please check the data sheets at the end of this manual for expected relay life. Current / Temperature De-Rating – Products containing relays often have total current limits based on the ambient temperature of the application. Please see the product data sheet for current / temperature de-rating information for relays. Fusing – External fusing is generally required to protect the relays, devices and wiring from shorts or overloads. WARNING: T o protect the module and associated wiring from load faults, use external (5A) fuse(s) as shown. F uses of lower current or fusing for the entire system need to be in place to assure the maximum current rating of the unit is not exceeded. WARNING: Connecting high voltage to any I/O pin can cause high voltage to appear at other I/O pins. Below is an example of Relay Fusing: Protection for Inductive Loads - Inductive loads can cause reverse currents when they shut off that can shorten the life of relay contacts. Some protective measures need to be determined by an engineer. Below you will find recommendations that will work for many applications. If you have additional questions on protection from inductive load, consult an application engineer or Horner Technical Support. Details on devices that may protect outputs can be found in the Spark Quencher Datasheet, MAN0962, which is located on the website. Page 86 of 206...

PWM State On Controller Stop - Contains items that allow the user to specify how the PWM outputs behave when the controller is stopped. These items can either hold their value or default to some value when the controller is stopped. NOTE: The PWM outputs are set to the OFF state at power-up and during program download and remain in that state until the unit is placed in RUN. Output State On Controller Stop - Contains items to allow the user to specify how the remaining digital outputs behave when the controller is stopped. These items can either hold their value or default to some value when the controller is stopped. NOTE: The number of Output States on Controller Stop vary by product. Stop State - When a controller stops running ladder logic, the state of most output I/O modules can be configured. By default digital outputs turn OFF and analog outputs go to a zero output level. Outputs can be configures to hold the last state the outputs was in when the controller stopped, or it can be configured to go to a predefined state. NOTE: When a controller is in DO I/O mode the outputs are still controlled by the values in the controller's registers. NOTE: The number of Output State on Controller Stop varies by controller.

Page 98: Scaling Analog Inputs & Examples
Chapter 8: General I/O Configuration 8.5.1 Scaling Analog Inputs & Examples To access the Advanced Math Scaling function, select Home > View > Project Toolbox. This will open a side bar, and then select Advanced Math > Scale. Example 1 The Cscape Scale function, found in the Advanced Math functions, allows for very easy conversion of the raw input value into a meaningful reading. For example, a pressure transducer may be specified as a 4-20mA signal to signify a 0-2000 psi pressure reading. W ith the analog channel set to the 4-20mA range, the raw analog input value, which is in INT format ranges from 0 to 4mA to 32000 for 20mA. Use the Scale function to obtain an Integer pressure reading using the 0-32000 raw input range and the sensor’s 0-2000psi output range. Example 2: If readings with fractions are required, the raw Integer input value must first be translated in REAL, or Floating Point Format, see note below. The Cscape INT-to-REAL Conversion function may be used to convert the raw input value from INT to REAL format in an intermediate memory location. The SCALE function, specified as REAL type, may be used to scale the converted raw value into a reading that supports digits beyond the decimal place, i.e. 475.25psi. Page 98 of 206...
Page 99: Analog Outputs
Chapter 8: General I/O Configuration 8.6 Analog Outputs NOTE: Refer to the datasheet for details on jumper settings. The analog outputs on Horner OCS devices provide high resolution voltage or current outputs. The voltage or current selection is controlled with jumpers and configuration settings in Cscape. NOTE: Each channel can be separately configured for voltage or current mode. When the controller is stopped, the operation of each output is configurable. The outputs can hold the state they were in before the controller stopped or they can go to a predetermined value. By default, analog outputs are set to a value of zero (0). The following figure illustrates the Analog Output Configuration dialog. To open the I/O configuration dialogs, select Controller > Hardware Configuration > Local I/O > Config > Module Setup. The Output value on Stop group box contains items that allow the user to specify how the analog output channels behave when the controller is stopped. The outputs can either hold their value or default to a value when the controller is stopped. The Output Mode group box allows the user to select the operating modes for each of the analog outputs. The modes include the following: 0-10V ...

9.5: HSC Functions Register Maps 9.6: High Speed Output Functions 9.7: High Speed Output Functions Register Map 9.8: HSC I/O Filtering 9.1: Overview In addition to the compliment of simple analog and digital I/O, several of the OCS I/O modules support High Speed Counting (HSC) I/O functions and may also support Pulse Width Modulation (PWM) Output functions (non-relay modules). The HSC functions include internal timing, frequency, totalizing, pulse width/period, and quadrature measurement. The PWM functions include traditional PWM (with variable rate and duty cycle) and a stepper (limited functionality) with variable acceleration and deceleration rates. The OCS contains a Field-Programmable Gate Array (FPGA), which is an integrated configurable circuit that allows the OCS to be programmed to have either two high-speed counters or four high-speed counters. The OCS ships with two high-speed counters, but a customer can contact Horner Technical Support to receive a file that will configure the unit to have four. These modes are not supported simultaneously. Two counter mode supports Quadrature mode and two stepper outputs, while four counter mode does not support Quadrature mode and supports only one stepper output. This chapter describes the operation of these high level I/O functions. For configuration details of these functions, see "Cscape Configuration". Page 101 of 206...

Page 103: High Speed Counter (Hsc) Functions
Chapter 9: High Speed I/O (HSC/PWM) 9.3: High Speed Counter (HSC) Functions The s upports two h igh speed, configurable counters. There are four dedicated inputs that can be configured to a number of different options. Each of the two counters can run in one of five modes. Those modes are Totalizer, Frequency Counter, Pulse Width Measurement, Period Measurement and Quadrature measurement. For some modes, more than one HSC input may be consumed. The measurement values are provided to ladder in a %AI register. Refer to the Register chapter for more details. 9.3.1: Frequency In frequency mode, the frequency of the input signal is written to the accumulator in terms of Hertz (cycles/second). When using frequency mode, four update selections are provided which specify the width of the sample window. NOTE: Selecting a shorter sample window provides a quicker measurement (faster response) but lowers the frequency accuracy (resolution) and increases the minimum frequency measurement limit. In this mode the Disable and Latch special functions are allowed. Refer to the"High Speed I/O Glossary " on the previous page"High Speed I/O Glossary " on the previous pagefor a description of these functions. 9.3.2: Totalize In totalize mode, the accumulator is simply incremented or decremented each time the input transitions in a specific direction. The totalizer supports the following modes: This mode ties the i nput to the counter to an internal 10MHz or 1MHz clock. The special f unctions Internal can be used to accurately time events. This increments ...
Page 104: 3: Pulse Width Measurement
Chapter 9: High Speed I/O (HSC/PWM) NOTE: Counter triggers off the rising edge of the signal. Three different options are available to reset the current count: The totalize function also supports an option which compares the current accumulator value with a supplied Preset Value (PV), which is provided through a %AQ, and drives a physical digital output based on the that comparison. NOTE: This option (available for HSC1 and HSC2 only) drives Q1 or Q2 output point (respectively) once the associated totalizer accumulator reaches (or exceeds) the PV value. To enable this function, the corresponding PWM function output (Q1 or Q2) must be configured for HSCx Output. NOTE: Q1 and Q2 are PWM function outputs that may be configured independently as one of the following: standard digital output, PWM, HSCx or stepper output. Preset values may be modified during run-time. A preset value of zero disables (resets) the totalizer compares function output causing the output to remain low. 9.3.3: Pulse Width Measurement In pulse width measurement mode, the high-speed input can measure the width of a pulse stream in one of two modes and provides a continuous indication of the last sampled value. In this mode the Disable and Latch special functions are allowed. Refer to the "High Speed I/O Glossary " on page 102 for a description of these functions. Width High 1 μs Counts – In this sub-mode the accumulator value will contain the number of 1 μs counts the pulse is high. Width Low 1 μs Counts – In this sub-mode the accumulator value will contain the number of 1 μs counts the pulse is low. Page 104 of 206...
Page 105: 4: Period Measurement
Chapter 9: High Speed I/O (HSC/PWM) 9.3.4: Period Measurement In period measurement mode, the high-speed input can measure the period of a pulse stream in one of two modes and provides a continuous indication of the last sampled value. In this mode, the Disable and Latch special functions are allowed. Refer to the "High Speed I/O Glossary " on page 102 for a description of these functions. Period Rising Edges 1 μs Counts – In this sub-mode the period of the input signal is reported in one (1) μs units. The period measurement will start on the rising edge of the input. Period Falling Edges 1 μs Counts – In this sub-mode the period of the input signal is reported in 1 μs units. The period measurement will start on the falling edge of the input. 9.3.5: Quadrature Quadrature mode uses two HSC inputs, any of the four HSC inputs can be assigned for this purpose.Quadrature mode works much like the totalizer except the accumulator will automatically increment or decrement based on the rotation phase of the two inputs. See the following example for more details. Quadrature inputs are typically used for reporting the value of an encoder. Two modes are available for quadrature that select whether the accumulator counts up or down when the phase of Input 1 leads Input 2. Check your encoder’s documentation to determine the output form it uses or try both modes to determine if the encoder counts up when expected. Using the above waveforms and a HSC input configuration of “Quadrature” - “1 leads 2, count up,” the accumulator will count up when 1 is rising and 2 is low, 1 is high and 2 is rising, 1 is falling and 2 is high, and when 1 is low and 2 is falling. This results in 4 counts per revolution. So in order to determine the number of cycles, the accumulator would have to be divided by 4. Marker reset operation is configured in the special operations and can be assigned to any of the 4 high speed inputs or can be assigned to be controlled by a “Q” bit in ladder. NOTE: The quadrature mode enables the Disable, Latch, Preload, Clear and Marker special functions. Refer to the "High Speed I/O Glossary " on page 102for a description of these functions.

Chapter 9: High Speed I/O (HSC/PWM) 3. The High-Speed Outputs are %Q1 for Counter 1 and %Q2 for Counter 2. They operate as high-speed outputs, independent of the controller scan rate, when configured as ‘HSC Output’ in the Digital Out/PWM configuration in Cscape. 4. The High-Speed Output state reflects in the status register “High Speed Out”, e.g. %I0009 for Counter 1 (the update speed of the status bit is scan rate dependent) 5. The High-Speed Output can be reset through ladder with the assigned output, e.g. %Q0022 for Counter 1 6. Both Match 1 and Match 2 values will trigger the match function. 7. If the output is already triggered by any Match register while using ‘Turn On’ or ‘Turn Off’ modes, subsequent matches will not affect the output. 8. If using ‘Toggle’ mode, every match of either Match value will toggle the output to the opposite state. 9.4: HSC Functions The high-speed input on the OCS contains many optional tasks. All of which can be disabled, or set to an internal pre-assigned register (Assigned %Q) or to one of the external high speed inputs (External Input #1, 2, 3, or 4), or they can be set as an “overflow interrupt” or “underflow interrupt” meaning that they will occur when either the Overflow or Underflow input has been activated. Disable: When the Disable function is active, it will “disable” the high-speed inputs and no longer count pulses until it is re-enabled Latch: When the Latch function is active, it takes the current value of the Accumulator and moves it into the “Latch Value” register Preload: When the pre-load function is active, it will take the value from the “Preload” register and put it into the “Accumulator” for the corresponding Counter. Clear: When the clear function is active, it will move a value of 0 into the “Accumulator” for the corresponding counter.

Page 111: High Speed Output Functions
Chapter 9: High Speed I/O (HSC/PWM) 9.6: High Speed Output Functions On units that support high-speed output functions, two dedicated outputs are available that can be configured for one of four modes of operation. Those modes are Normal, PWM, HSC Match and Stepper. 9.6.1: Normal When either Q1 or Q2 is configured for Normal operation, the digital output registers %Q1 and %Q2 drives that respective output. 9.6.2: PWM When either Q1 or Q2 is configured for PWM, the PWM function drives that respective output. Both PWM channels may be individually enabled and can have independent frequency and duty cycles. The PWMs require two parameters (%AQs) to be set for operation. These parameters may be set at run-time. Duty Cycle – The Duty Cycle is a 32-bit value from 0 to 32,000 indicating the relative duty cycle of the output. For example, a value of 8000 would indicate a 25% duty cycle, a value of 16,000 would indicate a 50% duty cycle. Zero (0) turns the output off, 32,000 turns the output on. Frequency – The Frequency is a 32-bit value indicating the output frequency in Hertz. One over the frequency is the period. At controller power-up or during a download, the PWM output is maintained at zero until both the Frequency and the Duty cycle are loaded with non-zero values. When the controller is placed in stop mode, the state of the PWM outputs is dependent on the PWM State on Controller Stop configuration. This configuration allows for either hold-last-state or specific frequency and duty cycle counts. Specifying zero for either the period or duty causes the PWM output to remain low during stop mode.

Page 118: Hsc I/O Filtering
Chapter 9: High Speed I/O (HSC/PWM) 9.8: HSC I/O Filtering This feature is used to enable digital Filter for HSC Inputs. Selecting Digital In/HSC configuration opens up the following dialog where in HSC I/O Filtering is available. Input signal is filtered based on the filter frequency and Number of samples selected. User has to select Filter Frequency and Number of samples based on the frequency of the Input signal. Filter Frequency: To set the filter, choose a value that is: 4*Number of Samples*Expected Max Hz on the high-speed inputs. Number of samples: The input must be stable for this many samples before the HSC accumulator is affected by any change. The state (high or low) of the high-speed input is sampled with every rising input edge of the filter frequency. The rising edges of the filter frequency are totaled in a sample counter, and when that total equals the number of samples configured, the sample counter is reset. I f the high-speed input state did not change by the time of the sample counter reset, that state, high or low, is passed on to the high-speed accumulator. I f the high-speed input state changes during the sample counting, the sample counter is reset to zero and the process starts over. Page 118 of 206...
Page 119 Chapter 9: High Speed I/O (HSC/PWM) If user selects filter frequency as 1MHz and Number of samples as 4, then Input signal is sampled for 4 samples and if the signal is stable for 4 samples i.e. 4μs then the signal is passed to Accumulator. If the Input state is changed in between the sampling counts, then the count is reset, and the Input state is again checked for given number of samples. Refer to Dotted lines in the Figure 2, after 2 samples the state of input signal changes to 1, so the counter is again started to count 4 samples, to pass the signal to accumulator. There will be a delay in passing the input signal to accumulator since we are filtering the Input signal and the delay is based on the selected filter frequency and Number of samples. In the above example filter frequency is 1MHz (1μs) and number of samples: 4, so the minimum delay in input signal will be 4μs. Page 119 of 206...

Net Mask: Enter the Net Mask (sometimes called Subnet Mask) being used by all nodes on the local network. Typical local networks use Class C IP Addresses, in which case the low octet (rightmost number) is used to uniquely identify each node on the local network. In this case, the default Net Mask value of 255.255.255.0 should be used. Gateway: Enter the IP Address of a Gateway Server on the local network that allows for communication outside of the local network. To prevent the Ethernet Module from communicating outside the local network, set the Default Gateway IP Address to 0.0.0.0 (the default setting). Status Register: Enter an OCS Register reference (such as %R100) to indicate which 16-bit OCS register will have the Ethernet Status word written to it. The table shows how this register value is formatted and explains the meaning of each bit in the Status Word. Page 131 of 206...

Chapter 12: Ethernet Communications 12.4 Ethernet Configuration – IP Parameters For primary operation, the IP address, Net Mask, and Gateway should be set in the LAN config of the Cscape Hardware Configuration. There are options to get IP parameters from the LAN Config or to get parameters from registers. It is possible to set the Ethernet IP parameters from the OCS System Menu, but only as a temporary measure. The following points on IP parameter configuration should be considered. IP Parameters in Non-Volatile RAM: The IP parameters of the Cscape LAN Config are written to non-volatile RAM on power down. IP parameter settings made in the System Menu are not written to non-volatile RAM. Any IP parameters settings made in the System Menu will be lost after cycling power to the unit. It will revert to the last downloaded Cscape LAN Config that was loaded into non-volatile RAM at power down. “Cscape LAN Config”/ “Get Settings from” Configuration: When ‘Get settings from’ is set to Configuration, the IP parameters specified under ‘Default Settings’ is used after downloading to the controller. The IP parameters are represented in System Menu / Set Networks and can be edited. However, any edits made from System Menu / Set Networks is not retained through a power cycle. After power cycle, the unit reverts to the last downloaded Cscape LAN Config that was loaded into non- volatile RAM at power down. “Cscape LAN Config” / “Get Settings from” Register: When ‘Get settings from’ is set to Register, the IP parameters are retrieved from the OCS registers assigned in LAN Config. Configured registers must be populated with the desired IP ...

This feature greatly expands the OCS’s control capability with negligible effect on the OCS ’s ladder scan time. Remote devices that communicate serially must do so under certain rules of data transfer known as a protocol. Many device manufactures have created their own protocol for communications with their device. F or a OCS to communicate with a specific device, it must be loaded with the corresponding serial communications protocol device driver that supports that protocol. A limited number of protocol device drivers are packaged with the Cscape distribution; however, as more are developed, they will be made available as add-on packages. A device driver is typically distributed as a Windows module, which contains the configuration menus, help files and the target executable driver code. W hen updating device drivers, an install routine loads the device driver to the Cscape directory structure and makes that driver available to Cscape applications.

W hile each protocol is somewhat different and can contain protocol specific field, all protocols typically support at least: Device Name - Specifies a tag name for this device. T his tag name is used in the Data Mapping configuration to identify this device. T his allows device addresses to be modified without the need to update all associated Data Mapping entries. Device ID - Specifies the target device communications ID or station address. Swap Words on 32-bit Data - I f a Scan List e ntry is configured to transfer 32-bits and this option is checked, the high and low 16-bit values are swapped when transferred between the target and OCS. Disable Device - From Cscape 9.90 SP3 and firmware 15.40 onwards, disable device feature has been added in protocol device configuration. This option is used to disable a particular slave configured in the network. Single bit register has to be configured to use this function. Setting the bit high disables the slave and OCS will not send any serial ( TCP for ethernet protocols) packets only to this slave until the bit is high. Setting the bit low enables the communication with the slave again.

Page 147: Displaying And Entering Data
Chapter 14: User Interface 14.2 Displaying and Entering Data Multiple objects are provided for displaying data such as virtual panel lights, push buttons, numeric value displays, bar graphs, meters, graphs and animated bitmaps. On the Canvas 7 , these graphical objects (through ladder manipulation of attribute bits) can change color, flash, or change visibility to attract operator attention. On objects that accept user input, the input is provided by touching the object or alternately changing an OCS register (i.e. function key registers). Objects that allow input generally have a raised 3D appearance. An exception is the binary type objects, such as buttons, which are shown in a depressed 3D appearance when in the ON state. Objects that normally accept touch input may be disabled through program control (through ladder manipulation of an attribute bit). If an object is disabled, the object’s representation changes to a 2D appearance. On objects that represent non-discrete information, more action may be required beyond that of simply touching the object. For example, the slider object requires the operator to touch and slide the control in the direction desired. Alternately, alpha-numeric entry objects invoke a pop-up alpha-numeric keypad for additional user input. The alpha-numeric keypad is discussed below. NOTE: If the numeric entry object displays >>>>>>>, the value is too big to display in the field or is above the maximum for an editable field. Likewise, if the numeric entry object displays <<<<<<< in a numeric field, the value is too small to display or is below the minimum for an editable field. Page 147 of 206...
Page 148: Alpha-Numeric Keypad
Chapter 14: User Interface 14.3 Alpha-Numeric Keypad To allow entry of a specific number or text, several of the input objects invoke a pop-up alpha-numeric keypad when the object is touched. An example of the alpha-numeric keypad invoked from a numeric input object is shown below. Once invoked, the operator may touch the appropriate keys to enter a specific value. When entering a value, the alpha-numeric keypad is in one of two modes [new-value or edit-value]. New-Value Mode - Generally, when the alpha-numeric keypad is first invoked, it is placed in new-value mode. Initially, the alpha-numeric keypad displays the current value with all the digits being highlighted. Once the first digit is entered, the current value is erased from the display and the new digit is placed in the first location. Thereafter, no digits are highlighted, and new digits are added to the rightmost position while the other digits are shifted left. Edit-Value Mode - Edit-value mode may be entered from the initial new-value mode by pressing either the left or right arrow key before any digit key is pressed. The result will be a single character highlighted. The user may then either touch a key to change the digit at the selected position (or the up and down arrows may be used to add or sub-tract (respectively) from the selected digit)t. The user may then use the left or right arrow keys to select a new position. Once the desired value is entered, pressing the Enter key moves that value into the object (and the corresponding OCS register) and the alpha-numeric keypad disappears. Alternately, pressing the ESC key any time before the Enter key cancels the operation, leaves the objects current value unchanged, and the alpha-numeric keypad disappears. NOTE: Each numeric entry object has a configured minimum and maximum value. If the operator enters a value outside of the configured range, the new value is ignored when Enter is pressed and the current object value is NOT changed. Page 148 of 206...
Page 149: Screen Navigation
Chapter 14: User Interface Since the alpha-numeric keypad services several different graphical objects, certain keys on the alpha-numeric keypad may be disabled (grayed) when the keypad is invoked for certain objects. The following describes the alpha-numeric keypad variation based on object. Alpha-Numeric Keypad Variations When editing a numeric value, the [ +/-] or the [.] key are disabled (grayed) if the object is NOT Numeric O bject configured f or floating-point value or a signed value. When editing a password value, the a rrow keys, [+/-], and the [.] keys are disabled. A dditionally, Password O bject overwrite mode is disabled. W hen entering digits, the pop-up keypad hides the value by displaying ‘*’ a lternately for each digit. When editing an ASCII value, an A SCII keypad is displayed. The ASCII keypad has 3 modes: numeric, symbols and alpha. In Alpha mode, the Caps Lock button may be pressed t o access ASCII ...
Page 150: Ladder-Based Screen Navigation
Chapter 14: User Interface 14.5 Ladder-Based Screen Navigation Ladder logic can use several techniques to control screen navigation. Coils can be tied to %D registers to make them screen coils. These coils have two modes: switch and alarm. If the ladder program energizes an alarm display coil, the screen associated with this coil is displayed and overrides the normal user screens. This is designed to show alarm conditions or to display other ladder-detected events. When the text coil is de-energized, the previous screen that was being viewed before the alarm is returned. The switch display coil switches to the associated screen when it is energized. Once it is de-energized, the screen remains until it is switched by the user or ladder. There is also a system register that can be used to for control-based screen navigation. %SR1 can be read to determine the current screen or written to change the current screen. R efer to the C scape Help File for more information on control-based screen navigation. 14.6 Beeper Acknowledgement The Canvas 7 c ontains an internal beeper that provides an audible acknowledgment when an operator touches a graphic object that accepts touch input. When the graphic object is enabled, a short 5ms tone is emitted. When the graphic object is disabled, a longer 100ms tone is emitted to announce that the graphical object is not currently accepting the touch input. If beep acknowledgment is not desired, the beeper function can be disabled from the System Menu. 14.7 Touch (Slip) Sensitivity Touch slip sensitivity is preset to meet most applications; however, adjustment is available to reduce the sensitivity for touch ...
Page 151: Alarms
Chapter 14: User Interface 14.8 Alarms Alarm presentation to the operator is highly configurable and beyond the scope of this document to describe fully. For more information, refer to the Graphics Editor help file in Cscape. This section presents a typical configuration thereby providing an introductory description on what the operator should expect. The alarm object is generally used to enunciate alarms to the operator. While the display characteristics of this object is configurable, it is generally displayed as a button that changes colors to indicate the highest state of the alarm(s) in the alarm group it is monitoring. The following indicates the priority of the alarm states and the default colors associated with these states. To view, acknowledge and/or clear alarms, the operator must access the alarm viewer. This is accomplished by touching an (enabled) alarm object. When accessed, the alarm viewer is displayed as pop-up alarm viewer dialog. Alarm Viewer The currently selected entry is highlighted in blue color which can be moved up or down by directly touching an entry. The current state of the displayed alarm is indicated by its color and optionally by an abbreviated indicator after the date/time stamp (ALM, ACK, RTN). The operator can acknowledge an alarm by selecting it from the list and touching the ACK button. The operator can also clear an alarm if that function is enabled in the alarm object. If not enabled, the Clear buttons are grayed and do not respond to touch. Once view operations are complete, simply touch the Esc button to remove the pop-up alarm viewer. NOTE: OCS registers %SR181 and %SR182 are available for ladder use, which indicate presence of unacknowledged or acknowledged alarm (respectively). The screen designer may implement these registers to switch screens or activate the beeper to attract the operator’s attention. Page 151 of 206...
Page 152: Removable Media
Chapter 14: User Interface 14.9 Removable Media The Removable Media Object is generally used to inform the operator on the current state of the removable media device and allow access to its file structure. The Removable Media Object is displayed as a button that changes colors to indicate the current state of the removable media device. The following indicates the device states and the default colors associated with these states. To view and perform file operations, the operator must access the removable viewer. This is accomplished by either touching an (enabled) removable media object or through the System Menu. When accessed, the removable media viewer is displayed as pop-up removable media dialog. NOTE: The Removable Media Object can be configured to open the removable media viewer at a certain directory complete with restrictions on transversing back up the file path. This may be used to restrict operator access to non-critical files. The currently selected entry is highlighted in grey color which can be moved up or down by directly touching an entry. File operations are accomplished by pressing the appropriate button at the bottom of the Removable Media Viewer. The configuration of the removable media object that invokes the Removable Media Viewer defines what buttons are enabled and available to the user. A button is grayed and does not respond to touch if configured as disabled. The ( Enter) button (if enabled) performs certain operations based on the selected file’s type: Change display to parent directory <DIR> Change display to child directory bmp, jpeg Display bitmap (if compatible format) Load application (if compatible model and version) Page 152 of 206...
Page 153: Screen Saver
Chapter 14: User Interface Alternately, the (enter) button can be configured to simply load the ASCII representation of the file path (including the file name) to a group of OCS registers. That pathname can then be used by ladder for opening and manipulating that file. Once view operations are complete, simply touch the Esc button to remove the pop-up removable media viewer. If the removable media is used in an application, the Removable Media Device requires changing by the operator, and the application is attempting to write to the removable media when it is removed, the screen designer should create objects that allow the operator to temporarily halt access to the removable media. This prevents corruption to the file system if the removable media is removed during a file-write sequence. The graphic objects should set OCS register %SR174.1 (when requesting the card be removed) and provide an indicator based on OCS register %SR174.2 (which indicates that it is safe to remove the removable media). 14.10 Screen Saver The Canvas 7 s creen backlight life is typically five (5) years when in continuous use. If the application does not require interaction with the Canvas 7 f or long periods of time, the backlight life can be extended by using the screen saver function. When enabled through the System Menu, the backlight is shut off (screen goes black) after a specified time of no touch activity on the screen. When the screen saver shuts off the backlight, any operator touch on the screen or function keys reactivates the backlight. NOTE: When the screen saver is active (backlight shut off), any initial touch activity on the screen (or function key) to reactivate the backlight is otherwise ignored by the Canvas 7. Any additional touch activity is also ignored by the Canvas 7 f or approximately one second thereafter. It is possible for the application to temporarily disable the screen saver by generating a positive transition to %SR57.16 (coil only) at a rate faster than the screen saver timeout value. This may be desired while waiting for alarm acknowledgement. 14.11 Screen Brightness The Canvas 7 p rovides a feature that allows screen dimming for night operation. To enable this feature, the application must access and control system register %SR57 (Display Backlight Brightness). Screen brightness is continuously variable by driving ...
Page 154: Touch Screen Pressure
Chapter 14: User Interface 14.12 Touch Screen Pressure The Horner Canvas series OCS controllers have a resistive touch screen that allows mechanically detecting touch events. The resistive touch screen works by measuring the resistance between two layers of conductive film. NOTE: T ouch creates contact between resistive circuit layers, closing a switch. With a unique change to the touch monitoring firmware user can measure the pressure being exerted on the touch screen. This feature has been added in some Horner Canvas series controllers. This allows the OCS programmer to be notified of the touch pressure and it can configure the pressure required to accept a touch event. There are two system registers that provide this touch feature: %SR9 (I/O Name - TCH_PRESSURE) - Records the highest-pressure level of the last touch on the screen that exceeds the threshold value set in %SR10. This is a range of 0 to 3000. Zero (0) indicates no pressure and 3000 is the maximum amount of pressure that can be measured. %SR10 (I/O Name - TCH_PRESSURE_TSH) - This register sets the pressure threshold to indicate a touch. A value of 200 is typically the lightest touch, 600 is moderate and 1000+ is a heavy touch. These new features allow customizing the feel of the touch screen and can be used to add unique user interface features such as having different operations depending on the force of the touch.

The Memory Card slot is equipped with a “push-in, push-out” connector and a microSD card can be safely inserted into the Memory Card slot whether the Horner controller power is On or Off.
Page 164: 1: Microsd File System
Chapter 16: Removable Media 16.1.1: microSD File System The microSD Memory Card slot uses the PC-compatible FAT32 File System. This means that a PC, with a microSD-compatible card reader, can read files that have been written by the Horner controller and can write files that can be read by the Horner controller. However, the Horner controller does not support long filenames, but instead implements the 8.3 filename format. This means that all file and directory names must consist of up to eight (8) characters, followed by an optional dot, and an optional extension with up to three (3) characters. Directories and sub-directories can be nested up to 16 levels deep as long as each path name string does not exceed 147 characters. 16.2: Using the Removable Media Manager The Removable Media Manager is an interactive Horner controller screen that performs the following functions: a. Display total capacity, and available space in kilobytes b. Browse file and directory lists c. Delete files and directories d. Format a microSD card e. Load and save application programs f. View screen capture bitmaps The Removable Media Manager can be accessed via the System Menu or by using Cscape to place a Removable Media Manager object on an application graphics screen.

Page 165: Log Data
16.3: Log Data Using Read and Write Removable Media function blocks, an application ladder program can read and write Horner controller register data in the form of comma-delimited files, with a .csv extension. These files are compatible with standard database and spreadsheet PC programs. In addition, an application ladder program can use Rename and Delete Removable Media function blocks to rename and delete files. 16.4: View and Capture Screens The Horner controller File System uses bitmap files with the .BMP extension or JPEG files with the .JPG extension to store Horner controller graphic screen captures. To view a captured Horner controller screen, use the Removable Media Manager to find and highlight the desire .BMP or .JPG file, and then press Enter. To capture an Horner controller screen, turning on the assigned Screen Capture Control Register will capture the current Horner controller graphics screen and write it to the microSD card using the assigned Screen Capture Filename. Before capturing an Horner controller screen, Cscape must first be used to assign a Screen Capture Control Register and Filename in the application. To do this, first open the User interface menu then select the Screen Capture item of the Config menu and then enter a Control Register and Filename. To capture an Horner controller screen, turning On the assigned Screen Capture Control Register will capture the current Hornercontroller graphics screen and write it to the microSD card using the assigned Screen Capture Filename.

Screen Capture - The screen capture function allows a bitmap or jpeg image of the displayed OCS screen to be written to the Removable Media card. c. Filename Counters - The filename counters can be accessed wherever Removable Media functions require a path name. A typical application is the auto-incrementing of a file name when doing screen captures. d. File Select - File Select is used to specify the register block that is used with the Removable Media Manager object ‘Write Selected Filename’ option. 16.7: Filenames The RM function blocks support the flash with a Windows standard FAT-16 file system. All names must be limited to the “8.3” format where the filename contains eight characters a period then a three-character extension. The entire filename including any path must be less than or equal to 147 characters. When creating filenames and directories, it is sometimes desirable to include parts of the current date or time. There are six special symbols that can be entered into a filename that are replaced by the OCS with current time and date information.

Page 179: Autoload
Chapter 18: Fail-Safe System 18.6: AutoLoad This System Menu option allows the user to specify whether the OCS automatically loads the application AUTOLOAD.PGM located in Removable Media. When the AutoLoad setting is enabled (set to YES), it can either be manually initiated or automatically initiated at power-up. The automatic initiation will happen only in the following two cases: When there is no application program in the OCS and a valid AUTOLOAD.PGM is available in the removable media of the device. When the program residing in onboard memory is corrupted and a valid AUTOLOAD.PGM is available in the removable media of the device. AutoLoad can be manually initiated when the SYS-F3 key is pressed (OCS can be in any of the following mode – Idle/Run/DOIO). This also requires a valid AUTOLOAD.PGM to be present in the removable media of the device. When the AutoLoad setting is not enabled (set to NO), OCS will be in IDLE mode and the application is not loaded. If the AUTOLOAD.PGM is security enabled, the user will be prompted to enter the password before loading the application. The application will be loaded from the Removable media only after getting the correct password. %SR164.6 can be set to enable AutoLoad feature. No = Does not load AUTOLOAD.PGM a utomatically w hen application program is absent or corrupted. Enable AutoLoad Yes = Loads AUTOLOAD.PGM file a utomatically f rom Removable Media when application program is absent or c orrupted. Page 179 of 206...

When the AutoRun setting is disabled (NO), the OCS remains in the IDLE mode after a Restore Data or AutoLoad operation. %SR164.5 can be set by putting the system into RUN mode automatically, once an AutoLoad has been performed or an Automatic Restore has occurred. If for any reason the AutoLoad-Run (Loading the AUTOLOAD.PGM automatically and OCS put in RUN mode) sequence does not succeed, a pop-up message box saying "AUTO-LOAD-RUN SEQUENCE FAILED" will be displayed. It will also show the reason for its failure. On acknowledging this message box, the AutoLoad-Run sequence will be terminated, controller will return to the first user-screen and will be placed in IDLE mode. No = OCS will be in IDLE m ode after AutoLoad or Automatic Restore. Enable AutoRun Yes = OCS will automatically b e placed into RUN mode after AutoLoad or A utomatic Restore. “Enable AutoLoad” displays the following options: No = Does not load A UTOLOAD.PGM automatically when application program is absent or corrupted.

Chapter 19: Modbus Communications Chapter 19: Modbus Communications 19.1 Modbus Slave Overview 19.2 Modbus Master Overview 19.3 Modbus Addressing Table For complete Modbus instructions, please refer to the Help file in Cscape. Modbus (serial) is a popular, de-facto standard protocol that allows industrial devices from multiple manufacturers to easily share data in real-time. For Modbus serial communications, the Canvas 7 c an act as either a Master or a Slave. Modbus protocol (serial) allows for one master and multiple slaves. The master always initiates the conversation by sending a request to a particular slave. Only the addressed slave will send a response when the request is completed. Should the slave be unable to complete the request, it returns the appropriate error response. Should the slave be unable to respond, the master’s ...
Page 184: Modbus Master Overview
When acting as a Modbus master, there are two primary mechanisms used by the Canvas 7 t o allow the user to specify the data to be read/written from/to the slaves. Modbus Master Function Block—This is for serial only. This is an advanced feature that should only be used in rare occasions. Protocol Config—The Protocol Config is configured in the Hardware Configuration dialog box in Cscape (serial). Refer to the Modbus Addressing section. This is the preferred method in most applications. After the protocol has been selected from the dropdown menu, the Network, Devices, and Scan List become available. The Protocol Config is configured on three different levels: Network—Parameters, such as the polling rate of the data scan, are specified along with timeout values, retry, and re- acquisition settings. Serial configuration, baud rate, parity, etc. are also set here. Devices—For every slave to be polled, configuration details are added in the Devices dialog box. This includes Slave ID (serial). Under Device Type, the Modbus addressing style matching that specified in the slave’s user documentation may be selected. For instance, some slaves specify Modbus addresses (i.e. 40,001), and others specify offsets (i.e. 0000). Hex or Decimal—Some specify addresses in hex, and others in decimal. By allowing the user to select the Modbus addressing style for each slave on the network, minimal address conversion is required. Also, if the slave is another Horner product (i.e. another OCS), the “Native Addressing” option can be selected (i.e. %R1, %M17, etc.), and this skips the conversion to Modbus style altogether. Scan List—This is where the specific Modbus addresses to be read/written from/to each slave are specified. Up to 32 words of data can be read at the same time. NOTE: Once configuration has been completed on the Network and Devices level, Modbus data can be directly read/written from graphics objects in the Cscape screen editor. This is available even if the Modbus register is not listed on the scan list. Page 184 of 206...
Page 185: Modbus Addressing Table
To access Canvas 7 r egisters, a Modbus Master must be configured with the appropriate register type and offset. This is usually accomplished with one of two methods: Method 1: The first method uses Traditional Modbus References, in which the high digit represents the register type, and the lower digits represent the register offset (starting with Register 1 for each type). Since only four register types can be represented in this manner, Canvas 7 M odbus Function Blocks pack several Canvas 7 r egister types into each Modbus register type. Starting addresses of each Canvas 7 r egister type are shown in the Traditional Modbus Reference column of the Mobus Table. Method 2: The second method requires the Modbus Master to be configured with a specific Modbus Command and Modbus Offset. The supported Modbus commands and the associated offsets are also illustrated in Modbus Table. Canvas 7 Modbus Master Mapping Expanded Trad. Modbus Maximum Modbus Reference Modbus Ref.

Page 191 Chapter 20: Firmware Updates Screen Caching on Boot-up Go to User Interface > Configure > Display Settings for enabling screen caching on boot-up option. To optimize graphics responsiveness at run-time, all user screens must be cached. This option allows a choice of whether caching occurs at boot-up, or immediately after boot-up. With this option "checked" - caching is included in boot-up and no screens will be accessible by the user until boot-up is complete. This will extend boot-up time depending on the number and complexity of user screens. With the option "unchecked" - caching occurs after boot-up and user screens are accessible sooner. During caching, a banner will appear on the screen, and graphics responsiveness will be noticeably slower. In either case the logic scan is not impacted. The logic scan will be active during caching whether o r not it is included in the boot- up process.

Check diagnostics to ensure controller passed self-tests. View Diags in System Menu or in Cscape, click Controller/Diagnostics. 3. Check data sheets to ensure proper wiring. 4. Ensure that hardware jumpers and software configuration for I/O match. 5. Check data sheets for voltage and current limits. 6. Take ladder out of the picture. From Cscape set controller to “Do I/O” mode. In this mode inputs can be monitored, and outputs set from a data watch window in Cscape without interference from the ladder program. Some I/O problems are only a result of a mistake in the ladder program. WARNING: Setting outputs ON in Do I/O mode can result in injury or cause machinery to engage in an unsafe manner depending on the application and the environment. 22.3: CsCAN Network For complete information on setting up a CsCAN network, refer to CAN Networks manual (MAN0799) by using Horner's Documentation Search page. Network status, node ID, errors, and baud rate in the controller System Menu are all in reference to the CsCAN network. These indications can provide performance feedback on the CsCAN network and can also be used to aid in troubleshooting. Page 198 of 206...
Page 199 Chapter 22: Troubleshooting 22.3.1: CsCAN Network Troubleshooting Checklist 1. Use the proper Belden wire type or equivalent for the network as specified in the CAN Networks Manual, MAN0799. 2. The Horner O CS does not provide 24VDC to the network. An external voltage source must be used for other devices such as SmartStix I/O. 3. Check voltage at both ends of the network to ensure that voltage meets specifications of attached devices. 4. Proper termination is required. Use 121Ω (or 120Ω) resistors at each end of the network. T he resistors should be placed across the CAN_HI and CAN_LO terminals. 5. Measure the resistance between CAN_HI and CAN_LO. If the network is properly wired and terminated, there should be around 60Ω. 6. Check for duplicate node ID’s. 7. Keep proper wires together. One twisted pair is for V+ and V- and the other twisted pair is used for CAN_HI and CAN_LO. 8. Make sure the baud rate is the same for all controllers on the network. 9. Assure shields are connected at one end of each segment—they are not continuous through the network. 10. Do not exceed the maximum length determined by the baud rate and cable type. 11. Total drop length for each drop should not exceed 6m (20’). A drop may include more than one node. The drop length adds to the overall network length.
