MAN1256-05-EN_EXLW_XLWP_UM 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 the EXLW/XLW PRIME OCS are “sourcing” outputs. This means the output applies a positive voltage to the output pin when turned ON.
MAN1256-05-EN_EXLW_XLWP_UM Relay Outputs Relay outputs are designed to switch loads that typically have high voltage or current requirements or require the isolation that relays provide. NOTE: The design of the EXLW/XLW PRIME OCS does not require external coil power for the relays to function.
MAN1256-05-EN_EXLW_XLWP_UM 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. If you have questions on protection from inductive load, contact Technical Support. Details on devices that may protect outputs can be found in MAN0962.
MAN1256-05-EN_EXLW_XLWP_UM Analog Inputs NOTE: See the data sheet for the EXLW/XLW PRIME OCS model being used for jumper settings. Refer to the Cscape Configuration chapter for more details. The analog inputs on the EXLW/XLW PRIME OCS allow voltage or current measurement from a variety of devices.
Universal Analog Inputs Model 6 Universal Analog Inputs The Universal Analog Inputs on the Model 6 IO board are unique from other Horner X-series input/output cards in that they are configurable through the module configuration instead of having to change jumper settings in order to setup the input type. To configure the Universal Analog input type: 1) Select Analog In to access the Analog Input Configuration menu.

MAN1256-05-EN_EXLW_XLWP_UM High Speed Counter (HSC) Functions The EXLW/XLW PRIME supports two very high 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.
Page 88
MAN1256-05-EN_EXLW_XLWP_UM Rising Edge Signal Falling Edge Signal NOTE: Counter triggers off the rising edge of the signal. Three different options are available to reset the current count. They are: • Configured reset value Counts per When configuring the Totalize function, a value may be specified under the column.
MAN1256-05-EN_EXLW_XLWP_UM 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 HSC Glossary more details.
MAN1256-05-EN_EXLW_XLWP_UM 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 HSC Glossary for more details.
MAN1256-05-EN_EXLW_XLWP_UM 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.
MAN1256-05-EN_EXLW_XLWP_UM Register Match Totalizer & Quadrature counter modes support a register match function. When the accumulator value matches either the Match 1 or Match 2 value configured in the corresponding %AQ registers, a high-speed output can Turn On, Turn Off, or Toggle. An internal %I register mirrors the output state whether the high-speed output is configured or not.
MAN1256-05-EN_EXLW_XLWP_UM 9.10 HSC Functions The high-speed input on the EXLW/XLW PRIME 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).

MAN1256-05-EN_EXLW_XLWP_UM 9.13 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. 9.13.1 Normal When either Q1 or Q2 is configured for Normal operation, the digital output registers %Q1 and %Q2 drives that respective output.
Page 99
MAN1256-05-EN_EXLW_XLWP_UM 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.
Page 100
MAN1256-05-EN_EXLW_XLWP_UM 9.13.4 High Speed Counter Match When either Q1 or Q2 is configured for HSC Output operation, their output state is based on a comparison between the counter accumulator and match registers. Refer to the Functions section for more details. 9.13.5 Stepper Function The EXLW/XLW PRIME supports two stepper functions, one on each high-speed output when in two counter mode.
Page 101
MAN1256-05-EN_EXLW_XLWP_UM The stepper provides two Boolean registers to provide stepper status: A high indication on this register indicates the stepper sequence can Ready/Done be started (i.e. not currently busy) and also when the move is completed. A high indication on this register indicates that one of the analog parameters specified above is invalid or the stepper action was Error aborted before the operation was complete.

MAN1256-05-EN_EXLW_XLWP_UM 9.17 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.
Page 106
MAN1256-05-EN_EXLW_XLWP_UM 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. If 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.

MAN1256-05-EN_EXLW_XLWP_UM CHAPTER 10: SERIAL COMMUNICATIONS 10.1 Overview All EXLW/XLW PRIME OCS models provide two independent serial ports, on the first 8-pin modular RJ45 connector, which is labeled MJ1/MJ2. The MJ1 serial port is RS232 while the MJ2 port is RS485. By default, MJ1 can be connected to the COM port of a PC running Cscape, for OCS programming.
MAN1256-05-EN_EXLW_XLWP_UM Figure 10.1 – Wiring & Dip Switches 10.4 RS485 Termination Proper RS485 termination minimizes signal reflections and improves reliability. Both the MJ2 and MJ3 serial ports allow an internal termination resistor to be placed across pins 1 and 2 by DIP Switch Setting. Only the two devices physically located at the endpoints of the RS485 network should be terminated.
MAN1256-05-EN_EXLW_XLWP_UM 10.6 Cscape Programming via Serial Port The EXLW/XLW PRIME OCS MJ1 and MJ3 serial ports support CsCAN Programming Protocol. If a PC COM port is connected to the EXLW/XLW PRIME OCS MJ1 or MJ3 serial port, Cscape can access the EXLW/XLW PRIME OCS for programming and monitoring. Programming can also be done via the CAN port, USB A port, or Ethernet.
MAN1256-05-EN_EXLW_XLWP_UM CHAPTER 11: CAN Communications NOTE: For additional CAN information, refer to the CAN Networks manual (MAN0799) on the Horner website. 11.1 Overview All EXLW/XLW PRIME OCS models provide A CAN network port, which is implemented with 5- pin connectors. The CAN port allows the EXLW/XLW PRIME OCS to exchange global data with other OCS/RCS controllers and to access remote Network I/O devices (SmartStix, Smart Blocks and Smart Rail Modules).
MAN1256-05-EN_EXLW_XLWP_UM 11.4 Cscape Programming via CAN The CAN port supports CsCAN Programming Protocol. If a PC has a CAN interface installed (via PCI card or USB), and the PC CAN port is connected to the EXLW/XLW PRIME OCS CAN port, Cscape can access the EXLW/XLW PRIME OCS for programming and monitoring. In addition, the EXLW/XLW PRIME OCS supports single-point-programming of all EXLW/XLW PRIME OCS and other OCS/RCS devices that are connected to the CAN port network.

MAN1256-05-EN_EXLW_XLWP_UM 13.4 Device List and Device Configuration Device List The Device List is reached from the Device button on the Protocol Config screen and provides a list of the configured devices on the Network. Devices must be created and exist in this list before corresponding Scan List entries can be created for this device.
MAN1256-05-EN_EXLW_XLWP_UM 13.5 Scan List This can be accessed from the Scan List button on the Protocol Config screen or the Mapping button on the Device List screen and provides a Scan List of the Data Mapping entries. To transfer data between the OCS and remote target, a Scan List must be created that defines each transaction.
MAN1256-05-EN_EXLW_XLWP_UM 13.6 Data Mapping Configuration (Scan List Entry) Update Type This field specifies the direction and what triggers the transfer of data between the OCS and target device for a mapping entry. Polled Read On every transaction scan, a read-only target device register(s) transaction occurs. Polled Read/Write On every transaction scan, a read target device register transaction occurs unless a local register value has changed.
Page 128
MAN1256-05-EN_EXLW_XLWP_UM Polled Read/Write/Init On every transaction scan, a read target device register transaction occurs unless a local register value has changed. The write transaction only updates those local registers that have changed in value. If several non-consecutive local registers (contained in a single mapping entry) change value between transaction scans, it takes several consecutive scans to write each changed register.
MAN1256-05-EN_EXLW_XLWP_UM CHAPTER 14: USER INTERFACE 14.1 Overview This chapter presents the user interface (or operator view) of the EXLW/XLW PRIME and some of the model specific characteristics of the EXLW/XLW PRIME as compared to the rest of the OCS line. This chapter does NOT cover building screens or using the Cscape graphics editor. For instructions on creating screens and using the graphics editor, refer to the Cscape help file [Editing Graphics Based OCS Screens].
MAN1256-05-EN_EXLW_XLWP_UM 14.2 Displaying and Entering Data Figure 14.1 – Example Screen 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 EXLW/XLW PRIME, these graphical objects (through ladder manipulation of attribute bits) can change color, flash, or change visibility to attract operator attention.
MAN1256-05-EN_EXLW_XLWP_UM 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 in Figure 14.2. Once invoked, the operator may touch the appropriate keys to enter a specific value.
Page 132
MAN1256-05-EN_EXLW_XLWP_UM Enter Once the desired value is entered, pressing the key moves that value into the object (and the corresponding OCS register) and the alpha-numeric keypad disappears. Alternately, Enter pressing the key any time before the key cancels the operation, leaves the objects current value unchanged, and the alpha-numeric keypad disappears.
MAN1256-05-EN_EXLW_XLWP_UM 14.4 Screen Navigation To allow the operator to change screens, a screen jump object is generally used. This object may be visually represented as a 3-D button (responding to touch) or remain invisible and logically tied to an OCS register. An optional system ICON may be configured for display along with the legend, which aids in identifying the object as one that causes a screen change, shown below).
MAN1256-05-EN_EXLW_XLWP_UM 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.
MAN1256-05-EN_EXLW_XLWP_UM 14.6 Beeper Acknowledgement The EXLW/XLW PRIME contains 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 enounce that graphical object is not currently accepting the touch input.
MAN1256-05-EN_EXLW_XLWP_UM 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. This section presents a typical configuration thereby providing an introductory description on what the operator should expect.
Page 137
MAN1256-05-EN_EXLW_XLWP_UM Alarm Viewer 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 similar to that shown in Figure 14.6. Figure 14.6 –...
MAN1256-05-EN_EXLW_XLWP_UM 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.
Page 139
MAN1256-05-EN_EXLW_XLWP_UM (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) 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.
MAN1256-05-EN_EXLW_XLWP_UM 14.10 Screen Saver The EXLW/XLW PRIME screen backlight life is typically five (5) years when in continuous use. If the application does not require interaction with the EXLW/XLW PRIME for 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.
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 XL 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.
Page 142
MAN1256-05-EN_EXLW_XLWP_UM 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.
MAN1256-05-EN_EXLW_XLWP_UM CHAPTER 15: VIDEO OBJECT for EXLW/XLW PRIME 15.1 Video Object Overview The Video Object feature allows two options for video type: Stream and Playback. The Video Object trigger is used to start, stop, and pause video, and the System Register provides the status of the video object, which supports various resolutions and frames per second.

MAN1256-05-EN_EXLW_XLWP_UM CHAPTER 16: REMOVABLE MEDIA 16.1 Overview All EXLW/XLW PRIME OCS models provide a Removable Media slot, labeled Memory Card, which supports standard microSD Flash memory cards. MicroSD cards can be used to save and load applications, to capture graphics screens and to log data for later retrieval. Figure 16.1 –...
MAN1256-05-EN_EXLW_XLWP_UM 16.3 File System for microSD cards The microSD Memory 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 EXLW/XLW PRIME OCS and can write files that can be read by the EXLW/XLW PRIME OCS. However, the EXLW/XLW PRIME OCS does not support long filenames, but instead implements the 8.3 filename format.
MAN1256-05-EN_EXLW_XLWP_UM 16.5 Using Removable Media to Log Data Using Read and Write Removable Media function blocks, an application ladder program can read and write EXLW/XLW PRIME OCS register data in the form of comma-delimited files, with a .CSV extension. These files are compatible with standard database and spreadsheet PC programs.
MAN1256-05-EN_EXLW_XLWP_UM 16.7 Using Removable Media to View and Capture Screens The EXLW/XLW PRIME OCS File System uses bitmap files with the .BMP extension or JPEG files with the .JPG extension to store EXLW/XLW PRIME OCS graphic screen captures. To view a captured EXLW/XLW PRIME OCS screen, use the Removable Media Manager to find and highlight the desired .BMP or .JPG file, and then press Enter.

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 EXLW/XLW PRIME can act as either a Master or a Slave.
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.
MAN1256-05-EN_EXLW_XLWP_UM 20.4 Modbus Addressing Table for EXLW/XLW PRIME Units To access EXLW/XLW PRIME registers, 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).
The OCS has safety circuitry built into the charging IC and additional external protection including fusing. These circuits were closely evaluated by UL and Horner engineering for use in hazardous environments. November 10, 2021 181 | 201...

MAN1256-05-EN_EXLW_XLWP_UM 21.7 Replacing the Rechargeable Backup Battery The XLW has an advanced battery system that uses a rechargeable lithium-ion battery. The battery powers the real time clock when power is removed. To store registers, the battery continues to power the OCS for less than a second after external power is removed. In this time the registers and other retentive data is saved to internal flash memory.

MAN1256-05-EN_EXLW_XLWP_UM CHAPTER 23: MAINTENANCE 23.1 Firmware Updates The EXLW/XLW PRIME OCS products contain field updatable firmware to allow new features to be added to the product at a later time. Firmware updates should only be performed when a new feature or correction is required. Warning: Firmware updates should only be performed when the equipment being controlled by the EXLW/XLW PRIME OCS is in a safe, non-operational state.
2) Save Firmware files to microSD card or USB, these are the removable media devices. 3) Update the firmware through the controller’s Firmware Update function NOTE: Files from the Horner website come as a .ZIP file which need to be unzipped and placed in the root of the drive for them to function properly.
If any of the version numbers are incorrect, verify the correct files were copied to the removable media device and repeat the steps above. For more Firmware Update information refer to the Firmware Update Manual, MAN1011, which can be found on the Horner website. November 10, 2021 191 | 201...
