  • Page 11: Inputs And Outputs

    2 Inputs and outputs This section explains how to connect sensors and actuators to the WMPro and how to power them. It starts with a description of the available inputs and outputs and a hookup example. The inputs and outputs are then described in detail separately. 2�1 Introduction The WMPro can use 24 V AC or DC, or 12 V DC as the power supply.
  • Page 12 I/O type Number Comments Temperature inputs For 1000 Ω sensors, e.g. Pt1000 or Ni1000. Measur- ing range 800 Ω to 1580 Ω (= -50 °C to +150 °C for Pt1000). They also act as digital inputs. Analog inputs for voltage 0 to 10 V, approx.

  • Page 13: Example

    2�2 Example Later on we will configure inputs and outputs, as well as a controller for a heating central as illus- trated below. 2�3 Electrical connection Here are some examples of different electrical connection options. 2�3�1 Power supply The WMPro can run off a 12 V DC or 24 V AC or DC power supply. If a 24 V power supply is used, the 12 V DC and 24 V DC terminals can be used, each with a 100 mA load.
  • Page 14 2�3�2 Temperature inputs The temperature sensors share just five earth connections (GND). That means that in some places, two wires will use the same terminal. The sensor impedance is about 1000 ohm, and the line impedance is insignificant. 4 ohm corresponds to about 1 degree. Long cables and cables subject to interference must be shielded.
  • Page 15 2�3�4 Digital inputs Digital inputs have an internal 12 V supply via a resistor, and the input must be connected to earth (GND) with a dry contact output. Equipment with open collector or open drain outputs can also be used, but remember that the WMPro GND is connected to the equipment ground – which may cause problems in some situations.
  • Page 16 2�3�6 Digital outputs Digital outputs sink current to earth (GND). The output transistors can handle 36 V DC and 0.5 A. If the WMPro has a 24 V AC/DC power supply, you can connect a supply voltage to the output relay, either 12 or 24 V.

  • Page 17: Communication

    3 Communication You will need a computer with a web browser in order to change settings and access the infor- mation in a WMPro. This section explains how to connect a WMPro to a computer or network. First, there is an outline of the various options that are available, and you will find out how to get started quickly and easily.
  • Page 18 The Connection Wizard is a small program that sets the computer IP address, searches for a con- nected WMPro and opens a browser. The program is available for download from the Support section of the Abelko web site www. abelko.se. It automatically runs a "route add" command and opens a browser.
  • Page 19 3�2�4 Creating a search path Still in the DOS window, type this command: route add –p 10.0.48.94 X.X.X.X and press Enter. (Replace X.X.X.X with your computer's IP address). Your computer will now act as a gateway for WMPro. The "-p" option means that the setting is permanent. You can remove it with "route delete".

  • Page 21 You might have to restart the computer to apply the changes. If your computer is usually connected to a network, you should make a note of the settings so you can restore them when you have fin- ished configuring the WMPro. 3�3�1 Changing the IP address in Windows 2000 and XP Right-click the "My Network Places"...

  • Page 23: Broadband Or Adsl Connection

    To browse to the device you normally need a fixed IP address – the IP address is the address you enter in the browser. If you use a portal service or WDB, you can use DHCP. This means that valid network settings are sent automatically to the device.

  • Page 25: Ntp - Network Time Protocol

    3�7 NTP – Network Time Protocol In NTP, network devices obtain the current time from an NTP server and use it to synchronise their internal clocks. From release 3.4, WMPro has a built-in NTP client. If the option is enabled, the internal clock is regularly synchronised with a specified NTP server and adjusted if the difference is more than 5 seconds.
  • Page 26 3�7�2 Time zone It is also important to set the right time zone. The NTP server does not know which time zone the client is in, so the time needs to be adjusted to create the local time. To set the time zone go to Set- tings/System/Information.

  • Page 27: Modem Connection

    If a WMPro is connected by modem, it cannot be accessed over the Internet. Modem connections are used quite rarely, most people preferring to use ADSL connections. If you are considering using a dialup modem or a GSM modem, see the Abelko support page at www. abelko.se for a description of modem settings.

  • Page 28: Sms Settings

    3�10 SMS settings Starting from release 2.1, you can send alarm text messages via SMS if a GSM or GPRS modem is connected to the WMPro. The modem must be working properly, and must have a SIM card that can be used to send SMS text messages.

  • Page 29: Login Settings

    The WMPro will usually attempt to send the first text message straight away. If this attempt fails for some reason, the WMPro initially waits five minutes before trying again. If it still does not work, the system waits for 10 minutes this time, followed by 15 minutes between attempts. The phone bill can quickly mount up if you set the alarm thresholds too low or if the system trig- gers lots of alarms for some other reason.
  • Page 30 3�11�1 Broadband login Enter the IP address of the login server and the username, select "Set", and enter the password. Choose a "Keep-alive interval" (how often you want the WMPro to log in) and click "Update". If you have specified a DNS server in 3.5, you can type the name instead of the IP address. (For example mail1.telia.com if Telia is your ISP).

  • Page 31: Monitoring Communication

    3�12 Monitoring communication If you are using a modem to connect a WMPro, the modem can sometimes hang. Contact with the installation is lost, and someone has to physically go to the modem and switch it off and on again. If you connect the power supply to the modem via a digital Communication output (DU8), the WMPro can restart the modem by itself...

    3�13 If all else fails Factory settings If you forget the IP number you configured for a WMPro, The WMPro can easily be reset to you will no longer be able to browse to it. If an operator the original factory settings. panel is connected, you will be able to view and change the IP number from there.

  • Page 33: Functions

    4 Functions This section is a general description of how the WMPro works. There are several ways of ap- proaching the subject, and the best description for you depends on what you are interested in. Most users do not need to worry about the details. That is why 4.2 describes how the WMPro works when it is used for standard tasks.

  • Page 34: Standard Controllers

    4�2 Standard controllers Before you can control something, you need to tell the WMPro what you want it to control. Using the controller tool, you can specify what kind of installation you are running. Before starting the con- troller tool you should configure all the inputs and outputs you will be using, and give them names. This makes the configuration process easier.
  • Page 35 Databases input and output at all. A channel is not just a passive con- tainer for data – it can also modify the information flowing through it. It can be used to scale the information and carry out conversions, for exam- ple volts to kPa for a pressure sensor.

  • Page 36: Definitions

    The scripts are stored in text form in the device, so there is no need for a compiler or other tools. If you use the controller tool, it creates the script and uploads it to the device, so the device knows what you want it to do.

  • Page 37: Sensors And Actuators

    5 Sensors and actuators This section explains how to change the settings for various types of sensor and actuator. The settings relate to the sensor type and to the information you want to store in the databases. You can also go to the channel page to change some of the settings directly. 5�1 Configuring sensors and actuators Sensors and actuators When you connect a sensor or actuator to a WMPro, you...

    Click on the name to start the configuration tool. Java must be installed on your computer. If you see a message similar to "Do you want to install and run signed applet distributed by Abelko", answer Yes.
  • Page 39 Click Apply Settings to upload the new settings to the device. Click Measure to obtain a new read- ing to check plausibility. Click Reload Settings to import the settings that were saved last. Important: Make sure you save the sensor settings before starting database configuration. You can use the drop-down list box at the top to quickly switch to another sensor or actuator.
  • Page 40 The hour and day databases have more options for you to choose from. Choose mean value as the database entry type, then click Add Database Entry to include it in the database. A new line appears in the field underneath, showing the entry for that particular sensor. Details of the highest and low- est room temperatures may also be interesting, so let's include them too.

  • Page 41: Temperature Sensors

    When you have finished changing the database settings, upload them to the WMPro by clicking Ap- ply Database Settings. If you want to change the name of a sensor, you will need to delete the old database settings and then create new ones. When you add or remove values to/from a database, the WMPro will be un- able to correctly interpret the remaining data.

  • Page 44: Analog Outputs

    5�5�3 Counters If you are using a pulse generator to measure a flow, the same sensor can be used to measure consumption. Alongside the four digital inputs that can be used as frequency inputs, there are four counter inputs. These inputs do not receive data from other sensors – instead they count pulses from the same sensor.
  • Page 45 The databases can accommodate up to 50 values per row. The number of rows, and therefore the stored history, is limited by the available memory. Because the available memory is constant, more values per row mean less space for rows. In other words you need to make choices about what you want to store, so that the databases cover the period you are interested in.

  • Page 46: Manual Control

    5�8�2 Names When you add statistical values to a database, they are automatically named by adding a prefix to the sensor name. If you click the Database tab in the View menu to open a database, you can choose the values you are interested in by name. You can use the channel list to change the name of a sen- sor, even if the databases already contain statistical information for that sensor.

  • Page 47: Controllers

    6 Controllers This section explains how to configure various types of controller. The settings determine which inputs and outputs are used and how they influence each other. 6�1 Configuring controllers Controllers To configure a controller, you need to tell the WMPro The WMPro is supplied with a tool which sensors and other inputs and outputs to use, and for configuring controllers.
  • Page 48 Control functions: A heating central controller has the following control functions: constant or compensated, with or without pump(s) and one or two actuators in sequence. 6�1�1 Controller for heating centrals Control functions To illustrate, we are going to define a new controller for a A heating controller has the fol- heating central.

There is a New option in A heating controller has the fol- the list of control outputs. You should choose this option if lowing pump options: you are using a "three-state actuator".
  • Page 50 Set value displacement There are two types of set value displacement: simple digital displacement, in which the size of the displacement is specified in the controller tool; and a displace- ment channel for more advance displacements. Examples include room compensation. Select the controller curve.
  • Page 51 P-area The P-area defines the devia- tion necessary in order to obtain a 100% output signal from the controller. The P-area is centred on the set value, so if the P-area = 10 K and the set value is 20 °C, the output signal is 50% when the actual value is 20 °C.
  • Page 52 Specify the delay, the email option and the alarm type for pump feed- back. The delay is time between the moment the feedback loop is inter- rupted to the moment the alarm is triggered. This value also specifies the delay before starting the spare pump or twin pump if they are installed.

  • Page 53: Viewing Controller Data

    6�2 Viewing controller data The "View" menu now contains separate tabs for each controller. Open a controller The controller data appears at the top of the page. You are not able to modify this data. If there is a curve, it appears in the middle of the page. You can use drag-and-drop to alter the breakpoints. For more advanced curve settings, see section 8.

  • Page 55: Controlling Three-State Actuators

    6�3�5 Transducer A transducer supplies the actual value to the controller. Two transducers can be connected to the WMPro, and they can generate the actual value in three different ways: the sensor with the lowest temperature, the highest temperature or the mean value of the two sensors. One of the transducers can also be used for the minimum threshold.

  • Page 56: Viewing Actuator Data

    When setting the period time, remember that the minimum running time is 1 second. When you have finished changing the settings, click Save. The WMPro now generates a script and restarts. The program also creates a configuration page under the View menu, called Actuator 1. You will not be able to see the menu until you reload the page.

(OUTSIDE, not (Limit 1 < Value > Limit 2)). Enter values for Limit 1 = 55 ºC and Limit 2 = 65 ºC. Enter times for On-filter and Off-filter.
  • Page 64 7�5�5 Deleting alarms To delete an alarm, select it then click the "Delete" button in the edit dialog. You cannot delete alarms that are being used by scripts. 7�5�6 Action channels If you select a channel as an action channel (this is optional) it will change according to the alarm status.
  • Page 65 The device has restarted because of a software error. Make a note of the circum- stances around the time the error occurred, and send the system log file to Abelko. If the error occurred some time ago, the information about the error is likely to have disappeared from the system log.

  • Page 67: Curves

    8 Curves This section explains how to create and change new and existing curves for compensated con- trollers, sequences, etc. 8�1 Control curves Control curves are used in order to influence the set value in the controller. You can use up to ten different curves in the WMPro. A curve tool is provided to help you create new curves and edit existing ones.
  • Page 68 You will now see the first curve in chart form. At this stage Curve tool you can select any of the nine other curves to edit them. You can find the curve tool in the Some of the curves will have names, while the others are advanced settings.

  • Page 69: Sequence Curves

    8�1�4 Editing a new curve Select a curve that has not been edited before, for example Curve 4. On the chart page, you can see there are only two breakpoints. In most scenarios, this will not be enough. To add more breakpoints, click Curve settings and enter the number you need.

  • Page 70: Curves For Three-State Actuators

    If you need more breakpoints you can open the curve in the edit window by clicking Curve settings. Click Save if you have made any changes, then open the curve for sequence 2. In sequence 2, the output voltage stays at 0 V until the output signal reaches 50%, climbing to 10 V when the output signal is 100%.

  • Page 71: Curves For Room Compensation

    8�4 Curves for room compensation A control curve is an easy way of setting the displacement if you want the controller to use compen- sation based on the room temperature. The chart below shows a curve with +3 K compensation at 15 ºC, no compensation between 19 and 21 ºC and –10 K at 30 ºC.

Continue in the same way for the next column until you have included all the database channels you are interested in. If there are not enough columns you will need to set up a new transfer.

  • Page 83: 11 Channels And Parameters

    11 Channels and parameters All variable data in the WMPro is handled by channels. There are 200 channels, of which the first 44 are reserved for the I/Os. Parameters store data that can only be changed by the user. 11�1 Channels All the variable data in the WMPro is handled by channels.
  • Page 84 When you check one of the boxes for the hour and day databases, the first unoccupied channel is reserved for this purpose. That means that the database channels will not be in any particular order. This does not really matter, but you may prefer things slightly more organised. In that case, simply wait until you have finished configuring everything else before adding the databases.
  • Page 85 11�1�4 Manual control You might need to set an analog input, say, to a particu- lar value during setup or service. All analog and digital outputs can do this automatically, but you can also set other channels manually. This function is time limited in case you forget that it is activated.

There is a solar collector on the roof, and we want to automatically start a pump when the temperature on the roof is three degrees higher than the bottom of the storage tank, and stop it when the difference has decreased by one degree.
  • Page 99 Select row function. In this example, we want to Edit parameter value. Select the parameter you want to edit, which in this case is "Diff.temp Sun- panel" We can also enter a help text if necessary. The parameter name is self-explanatory here so this field can be left blank.

  • Page 101: Graphical Programming

    15 Graphical programming This section is about graphical programming and a few other functions in the Advanced menu. The idea is to help you learn how to use the graphical programming tool, which opens up the powerful capabilities of the WMPro that are not available in the standard controllers. We cannot cover the rest of the Advanced menu as this would take too much space.
  • Page 102 Above the workspace there are two drop-down list boxes under Inputs. Change the input from CHANNEL to CALENDAR. In the list box underneath, choose the calendar function you want to use. Click Add Input. The red square in the workspace now contains an icon for the calendar function (a stylised clock).

  • Page 103: Inputs

    The program is now finished, and all you need to do is click Save. Since the tool creates and uploads a user script file, the WMPro has to restart. You will be unable to use the device for a few minutes. 15�3 Inputs An input is a data source that provides information to the graphical program.

  • Page 104: Operators

    Operators are icons that you add to the workspace between the inputs and the outputs to increase the range of things the program can do. The operators are classified by the number of inputs they have and by the type of signals they use. All operators have one output, to the right. They can have one, two or three inputs.

  • Page 105: Connecting Operators

    15�6 Connecting operators There are certain rules you need to follow when you connect the operators in the workspace. An input can only be connected to an output. The connection is made from left to right, in other words the input must be one column to the right of the output. An input can only be connected to one output, but a single output can be connected to multiple inputs.

  • Page 106: Example - Solar Collector

    15�9 Example - solar collector In the next example, we will program the control system for a solar collector pump. It will work like this: If the temperature in the solar collector is three degrees higher than the temperature at the bottom of the storage tank, the pump will start running and continue until the difference drops to two degrees.
  • Page 107 Next, create five inputs – two channels, two parameters and one calendar. Start by clicking on the square in the top left, select the input called "Sunpanel roof" and click Add Input. Click on the square underneath and insert "Accumulator bottom". Click on the next square down.
  • Page 108 Next, we need an operator that switches to on when the upper output is on, and off when the lower output is on. We will use an RS toggle switch. Click on the square in the fifth column of the second row, and add the RS operator.

  • Page 109: Example - Room Compensation In Controller

    15�10 Example – room compensation in controller We will now use the programming tool to add room compensation to the controller we configured earlier. We will need a room sensor, a control curve and a channel for set value displacement. Config- ure the room sensor as described in 5.3.

  • Page 111: List Of Operators

    15�11 List of operators Logical operators: and, or, exclusive or (a or b, but not both) and not (inversion). Comparison operators: a compared to b. If the condition is met, the output signal is 1, otherwise it is 0. The four mathematical operators: a + b, a – b, a * b and a / Mathematical functions: sine, cosine, absolute value and square root.
  • Page 112 If the b input (enable) is true (anything other than 0), the output signal is equal to the a input. If the b input is 0, the operator keeps using the old value as the output signal. In other words the signal is frozen. The RS toggle switch sets the output to 1 if the set input (a) is true.

  • Page 137: 18 External Units

    18 External units External units are units of various kinds that a WMPro is able to share information with as the master. Examples include expansion units to increase the number of available inputs and out- puts, a PLC or other subsystem, meters, etc. The WMPro uses RS485 to communicate with exter- nal units.
  • Page 138 WMPro expansion port. It is a proprietary protocol for Abelko units only. AeACom differs from the protocols supported by GFBI in that there is no need to configure the address, and the update times are highly predictable.

  • Page 139: Type Definitions

    Alternatively you might be interested in statistical values rather than all the individual values. The script language includes a routine for handling groups of external units of the same type. You can use the routine to calculate the mean value, the highest and lowest value and other statistics from a group of sensors.

  • Page 140: Setup

    18�3 Setup The "External units" section appears at the bottom of Settings/Advanced. This is where you can change the settings of particular external units. The units (all 100 of them) are listed in the Setup tab. They are colour-coded – unused units are white, GFBI unit are yellow and WMShare units are sky blue.
  • Page 141 The fields under Parameters contain communication and other settings. The external unit on the right is an expan- sion module with five digital outputs. Here, the Address field contains the Modbus address used by the device and the other fields are settings that are sent to the device. You can link parameters to channels, and if you have done so, it is the channel that determines which settings are sent to the device.

  • Page 142: Viewing External Units

    18�4 Viewing external units There is also an External units command in the View menu. Click the command to display a list of all activated units. Each unit has a header row followed by all the values handled by that unit. The maximum number of values is ten.

  • Page 143: Channel Connections

    Note that the list of external units is not updated until you click on Exter- nal units again in the menu. The sta- tistics, on the other hand, are updated every time you click on a header row. If you have not defined any external units, this page is empty.

  • Page 144: Emails From External Units

    The default value will be the channel value before the WMPro has established contact with the unit on startup. The Use default value field can be toggled between "As startvalue" and "As startvalue & on error". Choose the second option to also use the default value if there is an error in the external unit, in other words if the WMPro loses contact with it and it appears in red on the View page.
  • Page 145 You can define up to four recipients and configure emails for up to ten dif- ferent sensor types. The recipients are the same for all external unit emails. Click on an email row to display the Edit email dialog. Select the device type and the frequency.

    Seneca is an Italian company that produces a range of modules with inputs and outputs, using Modbus to communicate. If you go to the Abelko web site you can download .gpss type defini- tions for four Seneca modules. One of the modules has five relay outputs, one has five digital inputs, one has four analogue inputs and one has three analogue outputs.

  • Page 148 Abelko will add more type definitions for units as they are created and after they have been tested. You can also write your own type definitions, or you can ask Abelko to add support for a particular type of unit. There are more Seneca I/O modules that communicate via Modbus, not to mention the other manufacturers.

  • Page 149: Wmshare

    18�8�2 Combining units The WMPro and GFBI are both able to switch easily between different protocols and speeds. But certain units may be confused by communication they do not understand. Most protocols include protective mechanisms making it highly unlikely that they will misinterpret or become confused by extraneous traffic, but a lot depends on the particular imple- mentation in different units.
  • Page 150 The WMShare export tab contains 20 key/channel pairs. Choose a key name that is known to all the devices that will access the value. For example OUTDOOR would be a suitable name for an outdoor temperature you want to distribute. If there is an outdoor sensor at T1, for example, select that chan- nel to export.
  • Page 151 To import the outdoor temperature we defined in the export tab, we need to define a type with the key OUTDOOR. You should also give the type definition a name that actually means something – for example Outdoor temperature. 18�9�3 Defining a WMShare unit To create a WMShare unit, go to Settings/ Advanced/External units, then Setup.
