AppendRecordsToDb is a project designed to demonstrate how to use the RDb.AppendRecord method to add a group of records into a data table. One record (row) in the Data1 data table contains the values of the following tags (columns): RecordTimeStamp, LongInt, String, and Word.

The data that will be logged to the data table is stored in array-type tags named LongArray5, StringArray5, and WordArray5. The RecordTimeStamp value is assembled from the tags MinuteArray5, HourArray5, DayArray5, and the constants c_Month and c_Year before the record is logged to the data table. The BlockSamplingData tag is connected to the Blocking tag property of the data table and to the corresponding button in the visualization window.

The sampling method of the data table is set to Script-controlled (by RDb.AppendRecord procedure) – this means the data can be logged only from a script by calling the RDb.AppendRecord method. The time stamp source is linked to the RecordTimeStamp tag – records don't have to be logged in a chronological sequence.

The InitArrays script is defined via the Script Manager and initializes the array-type tags. This script is executed at project startup via the AfterStartProject script. The SaveArray script is started by pressing the Save array of records button in the visualization window and performs the logging of records to the data table. The values of the RecordTimeStamp, Word, LongInt, and String tags are set and the RDb.AppendRecord method is called inside the "for" statement (this sequence is performed five times). You can view the data logged in the data table via the trend or report viewer.

The RandomValue and Seconds tags defined in the project are used to hold the data received from the external application. The project also contains the RelianceValue tag, which is used to send the data to the external program (you can set its value in the visualization window). The external application is located in the <Project>\Main\Apps folder and it is automatically started upon project startup (the Project Options > Scripts > Other > After run project property specifies the Create_GlobalObject script, which is to run the program). Before the project is started for the first time, the external program needs to be started manually to register the COM object.

The project's main visualization window contains two buttons connected to the scripts that are used to start or terminate the external application. The window also contains three Display components linked to the RandomValue, Seconds, and RelianceValue tags. The Create_GlobalObject and Free_GlobalObject event scripts defined through the Script Manager are designed to start and terminate the external application (the CreateObject method is used to start the external application). The SendNewValue script is designed to send the value of the RelianceValue tag to the external application (this can be achieved by calling the SetValue method of the external application). The last object defined via the Script Manager is a periodic script named Read_ObjValues (its period is 0.3 seconds), which is used to read the values from the external program (the GetRandomValue and GetSeconds methods of the external program are used to read the values).

The external application, which is part of the example project, shows the current values of the two dynamically generated tags and the list of values received from the visualization application. The external program is written in Borland Delphi (Pascal) and supplied including the source code (the source code is located in the <Project>\Main\Apps\Source\External.zip directory).

ExportHistDataToCSV is a project designed to show how to export historical data from a relational database to a text file in the CSV format. It is assumed that the computer on which this project runs is equipped with Microsoft SQL Server with its instance named SQLEXPRESS and credentials preset when installing SQL Server from Reliance Add-On Pack. In case SQL Server has been installed in another way, it is necessary to customize the connection string (Project Options > SQL) and the value of the constant c_ConnectionString in the Define_DataExport script. A data table named IncrementalData is defined through the Data Table Manager. The Reliance SCADA system logs the table's data to the table named IncData contained in the database R_ExportHistDataToCSV in Microsoft SQL Server running on the same computer (both the database and the table will be created with Reliance once the project is started for the first time).

To export the historical data to the file, scripts defined through the Script Manager are used. The export itself is performed by calling the ExportHistDataToCSV procedure, whose definition is contained in the Define_DataExport script. The name of a physical table (in this case, it is "IncData", see the ExportHistDataToCSV script) is passed as a parameter to the procedure. In the same way, it would be possible to export historical data from any other table if multiple tables were contained in the database (it would be enough to pass the name of this table as a parameter to the procedure).

You can export either all the data logged to the table or data from a specific time period (time range). This can be configured in the visualization window named MainWindow. To export all data, deactivate the options Start and End. Otherwise, activate the options Start and/or End and enter the time range's start and/or end. Data export can be invoked by clicking on the Export button (this will run the ExportHistDataToCSV script).

BACnet is a project designed to demonstrate how a device is connected via the BACnet communication driver. BACnet is not only used for defining communication services. Among other things, it is also used to define a number of objects and their properties through which data is presented. In this project, there are tags representing the properties of all Reliance-supported objects.

A device named BACnet1 is defined via the Device Manager. Within the device, several tags are defined and divided into folders based on individual BACnet objects. Each folder contains tags whose value allows you to read or write the properties of an object.

The type of object is specified by the Object type option, the property is specified by the Property identifier option. The Instance number option is used to distinguish the objects. The data type of a tag is changed automatically depending on the selected property. However, it can be changed subsequently. To test the example with a real BACnet device, it is necessary to configure these properties based on the real program of the device. Not all objects need to be used within the program and the Instance number option can differ for each object. Not all properties within BACnet objects are compulsory. Thus, some tags might not be updated successfully.

Upon project startup, the tray-type window on the left side contains several buttons used to switch between the windows defined within the project. Individual project windows contain displays and data grids showing objects' data based on tag data types.

This alarm will remain active for the duration of the communication error. This is the difference from the alarm that is automatically triggered by Reliance when an error in the communication with a device occurs. It is an "event" type of alarm – it is triggered, but it does not remain active; Reliance does not check to see if the error condition still exists – this is a drawback).

Within the Modbus1 and Modbus2 devices, the CommError tag of type Bool is defined via the Device Manager. It is an internal tag (not a physical tag from a PLC). In addition, the CommError alarm defined within the same devices is linked to the CommError tag. The alarm is triggered by the leading edge of the tag value (the off-to-on transition).

The Modbus1 and Modbus2 devices are connected to the PC1 computer via the Project Structure Manager. The communication options are defined through the Channel1 object that represents a communication channel. On the Advanced page of the channel properties, there are links to scripts to be executed when communication with the respective device is started, interrupted due to an error, and restored. The full name of the communication channel (device name/channel name, e.g., Modbus1/Channel1) is automatically passed to these scripts. This information is available in the scripts as the value of the SenderName property. This allows you to choose the same scripts for both devices' communication channels.

The Define script, which contains the definition of the SetDeviceCommError procedure, is defined via the Script Manager. On the Advanced page of the script's Properties pane, the Run on thread initialization option is active to execute the script prior to any other script supposed to run in the same thread of execution. The SetDeviceCommError procedure is called from a script named DeviceCommError, which executes every time that an error in communication with the device occurs, and from a script named DeviceCommStarted, which executes every time that communication with the device is started or restored. The SetDeviceCommError procedure has the following parameters:

FullChannelName: the full name of the communication channel (device name/channel name, e.g., Modbus1/Channel1)

CommError: the value of True or False (determines whether there is an error in communication)

The SetDeviceCommError procedure first splits the value of the FullChannelName parameter into the device name and the channel name and then writes the value of the CommError parameter to the internal tag CommError in the respective device by calling the RTag.SetTagValue method. This results in triggering a new alarm or ending the existing one.

Generic_SimpleText is a project designed to demonstrate how the Generic device is used to read data from any device in the form of a text string. A device named Generic1 is defined via the Device Manager. Within the device, several special tags whose values are used for the communication are defined.

The InCount tag's value specifies the number of characters (bytes) received by the tag of type Input buffer.

The InBuffer tag is an array of bytes containing received data.

The InString tag is a string containing received data in a text format.

The OutCount tag's value specifies the number of characters (bytes) sent from the tag of type Output buffer.

The OutBuffer tag is an array of bytes containing data to send.

The Control tag's value is used to control sending data.

In this example project, no data is sent, the Control and OutCount control tags are only used to open the communication port.

The main visualization window contains a button used to open the communication port. To do so, the Control tag's value is set to logical 1 and the number of bytes to send in the OutCount tag is set to 0 via a script.

The two Display components are used to show the received character count and received data in the form of a text string.

The other button is used to reset the received character count and delete the input buffer.

Generic_Teco is a project designed to demonstrate how a communication protocol is implemented and how a device is connected via the Generic communication driver. In this example project, the EPSNET protocol of the Tecomat PLC is chosen.

A device named Generic1 is defined via the Device Manager. Within the device, several special tags whose values are used for the communication are defined.

The InCount tag's value specifies the number of characters (bytes) received by the tag of type Input buffer.

The InBuffer tag is an array of bytes containing received data.

The OutCount tag's value specifies the number of characters (bytes) sent from the tag of type Output buffer.

The OutBuffer tag is an array of bytes containing data to send.

The Control tag's value is used to control sending data.

The PacketName tag provides an easy way to identify the communication packet in the communication statement or in the log file. If this tag is not used, its default name Packet is displayed in the statement.

In addition, an internal tag named Ethernet is defined. Its value determines whether a serial cable or Ethernet is used for communication. The value should be reflected when creating custom communication packets.

The main visualization window contains several controls intended for configuring and controlling the communication itself. The following communication packets can be sent: a packet for establishing communication, a packet for reading a data block from any register and address, a packet for reading/writing data from/to a tag of the selected data type from any address. By pressing the respective button, a communication packet will be created via a script according to the specified configuration settings and sent to the communication channel.

In the middle part of the window, sent and received data is displayed in a tabular format. In the top right corner, the control and status tags' values are shown.

In the bottom right corner, the checking tags' values read from the PLC by the Teco native communication driver are displayed (these tags lie on randomly selected addresses).

In order for the example project to be fully functional, it is necessary that the Ethernet option's value be set in compliance with the channel type specified through the Project Structure Manager.

OPC_DeviceCommStatus is a project designed to demonstrate how to use a script to determine the state of an OPC server by testing the quality of a tag. Via the Device Manager, you have to configure the OPCDevice1 device according to your local OPC server. The OPC group of this device contains an internal tag that is periodically tested in the script (if the tag quality is not 'Good', it means that the OPC server is not connected). For this purpose, the Random_UInt1 tag is used in the project. The project also contains the OPCDevice1Connected tag that, after the script is evaluated, contains information regarding the OPC device connection status and is linked to the Active Text component placed in the visualization window.

In addition, the Define script, which is executed at the thread initialization, is defined via the Script Manager. This script defines the procedure that evaluates the tag quality (it is more effective to define a procedure than to write the code directly into the script's body). The script reads the Random_UInt1 tag value with the RTag.GetTagValue method. Each method of the Reliance objects sets the value of the RError.Code property. If the value of this property is not equal to zero, an error occurs. To ensure that 'Bad' quality of the value is considered an error, the Treat invalid tag value as error option must be enabled (Project Options > Scripts > Other). The procedure is called from the UpdateOPCDeviceCommStatus script with the period of one second.

OPC_RemoteServer is a project designed to demonstrate how to connect Reliance's runtime software to an OPC server that is not running locally. The OPC1 device of type OPC is defined via the Device Manager. The OPC server Prog ID property allows you to select the OPC server for the device (e.g., from the local network). The PC1 computer, to which OPC1 is connected, is defined via the Project Structure Manager. On the Driver page of the device's Channel1, the Connect to driver property is set to On remote computer. Also the computer name is specified (RemotePC). The RemotePC computer is the second computer defined via the Project Structure Manager. This computer's only purpose is to identify the remote computer on which the OPC server is running. It holds the IP address of the OPC server (the Basic page).

Note: This type of connection to a remote OPC server is not advised because of certain drawbacks. The recommended way to connect to an OPC server is via Reliance's runtime software running on the remote computer. This means that the Reliance data server is running on the same computer as the OPC server and connection to other computers of the visualization project is provided via Server Connection Groups or via thin clients.

Teco_Databox is a project designed to demonstrate how to transfer data from/to the Databox memory of the Teco device. Via the Device Manager, the Tecomat1 device of type Teco and its IP address are defined. On the Databox page, the Enable reading/writing Databox option is active and the links to the respective tags defined within the System device are specified. The following tags are defined within the System device: The Control of type Byte tag is used to control the data transfer from/to the databox (0 – ready, 1 – read, 2 – write). The Status tag of type LongInt is connected to the Active Text component placed in the visualization window and indicates the activity that is being performed with the databox (Ready/Reading/Reading completed/Read error/Writing/Writing completed/Write error). The DataLength and DataOffset tags are used to define the range of data to be transferred from/to the databox. The current data range is accessed via the DataBuffer tag of type Array of Byte.

The visualization window contains a Data Grid component (Databox data) that displays the values of the DataBuffer tag and the corresponding index of the data in the databox (the IndexArray tag). The latter tag is automatically updated in the InitIndexArray script every time the databox is accessed (read or written).

BoilerRoom_MultipleServers is a project that adds a second server computer (Server2) to the BoilerRoom_ClientServer project. Server2 communicates to the BoilerRoom2 device. In this case, Server1 only communicates to the BoilerRoom1 device. This project demonstrates how to configure a client computer to access data from both servers at the same time. Each server provides the client with the data and alarms/events from a different device. The most important thing is creating two server connection groups for Client1 through the Project Structure Manager. Each group contains one server connection (Server1, Server2). To avoid displaying the top tray on the Server1 and Server2 computers, the TopTray window is disabled on the Display page (Disabled windows).

BoilerRoom_RedundantServers is a project that adds a second server computer (Server2) and a second client computer (Client2) to the BoilerRoom_ClientServer project. The computers are defined through the Project Structure Manager.

The Server1 and Server2 computers are redundant servers. Server2 is a secondary server to Server1 (primary server). The respective settings have been configured on the Redundancy page of Server2 (redundancy can be switched on/off through the Secondary server option). Only the server that has the active role provides (in this project) the following functions: simulation of tag data using scripts (analogy to communication with devices in a real project), historical data acquisition, alarm/event generation. Under normal circumstances (i.e., if both servers are running and connected with each other), the primary server has the active role. The secondary server has the standby role, i.e., it does not simulate data, all data (current and historical) and alarms/events are acquired from the primary server (it acts as a client towards the primary server). In the event of a primary server failure, the secondary server will assume the active role. Once the connection with the primary server is reestablished, the secondary server will again assume the standby role.

The Client2 computer has been created by duplicating Client1. A second server connection (pointing to Server2) has been added to the server connection group (named Servers) of the Client1 and Client2 computers. The connection priority is set so that Client1 is primarily connected to Server1 and Client2 is primarily connected to Server2. This setup provides load balancing. If one of the servers is not available (e.g., Server1 is terminated), its client automatically connects to the other server. If a client is not connected to its preferred server, the availability of the server with a higher priority is periodically tested. At runtime, you can view the connection status on the Network connections page in the System Information window.

AccessDLLFromScript is a project designed to show how to call functions exported by DLL (dynamic-link library) from a script. The VBScript language, which is used for writing scripts in Reliance projects, does not itself support calling DLL functions. This limitation can be worked around by using a utility called DynaCall, which can, at runtime, create an object-like wrapper around any DLL so that its functions could be called even from VBScript code.

DynaCall utility installation instructions:

1. Unpack the ZIP archive named DynaCall.zip (located in AccessDLLFromScript\Main\Apps) to any directory, e.g., c:\Program Files (the following directory will be created: c:\Program Files\DynaCall).

2. From the command prompt (cmd.exe), register the file c:\Program Files\DynaCall\dynwrap.dll by the following command: regsvr32.exe "c:\Program Files\DynaCall\dynwrap.dll".

Note: If the above command ends with an error, it is necessary to use the following steps:

3. Create a shortcut to cmd.exe.

4. From the context menu of the shortcut, choose the Run as Administrator command and confirm launching the program.

5. Repeat step 2.

The project contains a script named Example1_user32.dll_MessageBox, which makes it clear how to call DLL functions from scripts. The script demonstrates calling the MessageBoxA function from user32.dll (one of the fundamental DLLs of Windows) and can be run by clicking a button located in the main window of the project.

In the script, the below steps are used:

1. Create the DLLWrapper object by the following statement: Set DLLWrapper = CreateObject("DynamicWrapper").

2. Register the respective function by calling the Register method.

3. Call the function as a method of the DLLWrapper object, e.g., Result = DLLWrapper.MessageBoxA.

The steps taken to register the MessageBoxA function must be repeated for all other functions that are to be called.

Important:

1. The object variable DLLWrapper must be declared as local (inside a procedure) in the same way as in the example. If it were declared as global and the DLLWrapper object were not freed (by using Set DLLWrapper = Nothing) before ending the project, the runtime software would hang during ending the program.

2. The DynaCall utility is free of charge and its authors deny any responsibility for damage caused by possible malfunctions of the utility.

AutomaticUserLogOff is a project designed to demonstrate how to automatically log off the current user from the runtime software after a certain time of mouse and keyboard inactivity.

The LogoffUser script defined via the Script Manager is used to log off the current user by calling the RUser.LogoffUser method. In order for the script to be run after a certain time of inactivity, some parameters in the project's main file (the one with an .rp4 extension) must be altered. The project's main file is a text file that can be opened, for example, with the Notepad program (Notepad.exe). The parameters are stored in a section named [Section50] and have the following meaning:

Param0 – the inactivity time period (in milliseconds) after which the script specified by Param2 should be run

Param1 – determines whether to run the script specified by Param2 (0 – disabled, 1 – enabled)

Param2 – the ID of the script to be run

Note: The script ID is displayed in the bottom left corner of the Select Script dialog box.

Example:

[Section50]

Param0=20000

Param1=1

Param2=10

CustomRecipeEditor is a project designed to demonstrate how to use visualization windows and scripts to implement the features of the Recipe Editor, which is available at runtime. This should be done in cases where a customer requires to edit recipes through a form (not by editing values on the list of recipe items through the Recipe Editor).

A recipe type named Product01 is defined via the Recipe Manager. This recipe type contains 4 items named Param01, Param02, Param03, and Param04. Each item is connected to the corresponding same-named tag defined within the PLC1 device. When loading a stored recipe into the PLC1 device, the value of the respective item is written into these tags. To edit the recipe through visualization windows, one auxiliary tag must be defined for each recipe item (this auxiliary tag is of the same type as the corresponding tag in PLC1). The auxiliary tags are called editing tags. They are defined within the System device with the same names as the tags in PLC1. Each recipe item is connected to the corresponding editing tag. Also, each editing tag is connected to the corresponding Display component located in the EditRecipe_Product01 window. The Display components allow you to edit the values of the recipe items. To show the EditRecipe_Product01 window, click on the Edit Recipe button in the main visualization window (Product01). The EditRecipe_Product01 window can be used to choose a recipe from the list of already stored recipes, edit it, and save it under the specified name. The Product01 window can also be used to load or delete the selected recipe by clicking on the respective buttons.

DeclareArrayVar is a project showing how to define and use global and local array variables. The main visualization window contains two buttons that start the UseGlobalArrayVar and UseLocalArrayVar scripts.

An event script named Define used to declare the global variable GlobalArrayVar1 is defined via the Script Manager. This script is executed only once and prior to all other scripts, because the Run on thread initialization property on the Advanced page is enabled. The script is also executed upon a possible forcible termination of the thread. Each global array variable has to be declared only once to avoid the Type mismatch error.

The UseGlobalArrayVar script writes data to the global variable GlobalArrayVar1, whereas the UseLocalArrayVar script modifies only a local variable named LocalArrayVar declared inside the DoSomethingWithLocalArrayVar procedure.

DownloadAndSaveFile is a project designed to show how to download and save a file defined by a URL to a local computer. The project's main functionality is done in the DoDownloadAndSaveFile script. This script downloads the file based on the string values of the FileURL and FileName tags. The FileURL tag is linked to the corresponding Display component in the visualization window and defines the source file name and address (the URL has to be entered with the leading http://). The FileName tag is linked to the second Display component and defines the target file. To execute the script, press the Download File button.

The CreateObject command is used to create an instance of the MSXML2.XMLHTTP object. The open and send methods of this object are used to make the connection. The file is saved to the disk via the methods of the "ADODB.Stream" object.

ExtractBits is a project designed to demonstrate how to use scripts to extract bits from an integer tag and store the bit values in tags of type Bool.

Within the System device, the following tags are defined via the Device Manager: Status01 and Status02 of type Byte, Bits_Status01 and Bits_Status02 of type StatusBits, which is a data structure (defined via the Data Structure Manager). The Bits_Status01 (or Bits_Status02) tag is a structured tag that contains several nested tags of type Bool to which a script will write the value of the respective bits of the Status01 (or Status02) tag.

The Define script, which contains the definition of the ExtractBits procedure, is defined via the Script Manager. On the Advanced page of the script's Properties pane, the Run on thread initialization option is active to execute the script prior to any other script supposed to run in the same thread of execution. The ExtractBits procedure is called from the StatusChanged procedure that is called from the same-named script. The StatusChanged script executes every time the value or quality (validity) of the Status01 tag (or Status02) changes. This is ensured by linking the Status01 and Status02 tags to this script on the Device Manager's Scripts page. The quality (validity) is always changed upon project startup.

The following parameters are passed to the ExtractBits procedure:

The name of the device in which the source tag is defined: System

The name of the source tag: Status01 (or Status02)

The name of the device in which the target tag is defined: System

The name of the target tag (including the character used to separate the structured tag and its nested tags): StatusBits01/ (or StatusBits02/)

The array containing the numbers of bits to extract: BitNumbers_StatusBits = Array(0, 1, 4, 5)

The array containing the names of the fields of the StatusBits data structure (in the same order as bit numbers in the BitNumbers_StatusBits array): BitTagNames_StatusBits = Array("ManualMode", "EmergencyMode", "CheckDevice", "Error")

To display the data of the structured tags of type StatusBits, the same-named window template is used (see the Window Manager). This template contains Display components linked to particular fields of the StatusBits data structure. The template is embedded into the window named MainWindow through a Container component. The window also contains a Display component that is used to display the value of the Status01 (or Status02) tag and enables you to change it.

The solution described above has proven to be very convenient. There may be many tags like Status01 each of which contains status information on a machine used in the industrial process being visualized. It is very easy to add a new status tag. Simply duplicate the Status02 and Bits_Status02 tags. There is no need to modify the existing scripts and add new scripts.

CheckHDSerialNumber is an example project designed to demonstrate how to easily protect a project from being launched on an unauthorized computer. After the protection is activated, the project is bound to the hard disk serial number and cannot be run on another computer. Two tags named HDSerialNumber and CheckEnabled are defined through the Device Manager. The first one contains the serial number, the other one is used to activate/deactivate the protection.

Three scripts are defined through the Script Manager. The UpdateHDSerialNumber script is intended for updating the disk serial number in the HDSerialNumber tag. The ExitRuntimeModule script is used to terminate the project. The ProjectRun script is used to compare the current disk serial number to the value of the HDSerialNumber tag. If the numbers do not match, the Dlg_ProjectCannotRun dialog window is displayed. After the dialog is confirmed by clicking the OK button, the project is terminated.

All instructions listed below are also shown in the visualization window.

Disk check activation instructions:

1. Start the runtime software.

2. Save the current hard disk serial number to the HDSerialNumber tag (click on the Save HD serial number button).

3. Terminate the runtime software.

4. Bring up the Device Manager. On the Advanced page of the CheckEnabled tag's properties, activate the Save last value option.

5. Start the runtime software.

6. Start checking the hard disk serial number (click on the Check serial number check box).

7. Terminate the runtime software.

Disk check testing instructions:

1. Start the runtime software.

2. Change the saved value of the HDSerialNumber tag (using the Display component).

3. Terminate the runtime software.

4. Start the runtime software.

LogMessage is a project designed to demonstrate how to log a text string to a file from a script. The button located in the main visualization window is used to start the LogMessageTest script that contains the LogMessage procedure. This procedure is defined within the Define script (also the functions for custom date and time formatting are defined within this script). Access to the file is done via an object named "Scripting.FileSystemObject" (the OpenTextFile method of this object is used). If this method is called with the filename as a parameter, a new object is created (the numerical parameter defines the opening method, 1 – read only, 2 – write, 8 – append, and the logical parameter defines whether the file should be created if it doesn't exist). Now, you can call the WriteLine method of this object and write an arbitrary text string to the file.

If the button located in the main visualization window is pressed at runtime, a new directory named Logs is created in the <Project> directory. The ScriptLog.txt file is created in this directory. The file contains lines with a current date, time, and example text string.

ScriptTypes is a project designed to demonstrate how to use different script types. The main visualization window contains five panes, each demonstrating features of one script type. The first pane introduces the Periodic script – the angle value is periodically incremented. The second pane introduces the Data change script – if you change the value of A, B, or C, the result is automatically recalculated. The third pane introduces the features of the Key script – if you press the F5 button, a dialog window is shown (all scripts run in the same thread and, therefore, other scripts are paused if the dialog is shown).

The fourth pane introduces the Condition script – if you enter a number greater than 10 into the Display component, a dialog window is shown. The last pane introduces the Event script – the buttons are linked to the digital tags. An alarm/event is defined and starts if the tag value changes from logical 0 to logical 1. The Alarm script is linked to the event of alarm/event start. The script reads the text of this alarm and shows it in a dialog window.
