Object 'Data Source Manager'dl-permalink__symbolPermalink

Symbol: _visu_icon_data_sources

The object is used as a node for data sources below it. At least one data source has to exist. An application with the data source manager communicates with remote devices.

Command 'Add Object' > 'Data Source'

Function: The command opens the “Add Data Source” dialog.

Call

  • Menu bar: “Project”

  • Context menu in the “Devices” view of the CODESYSperspective

  • Context menu in the “Data Sources” view of the “HMI” perspective

Requirement: The “Data Source Manager” object is selected that should have an additional data source.

Dialog 'Add Data Source'

“Name”

Example: ‎Data_Source_A‎

“Select data source type”

Data source type that matches the controller configuration in order to establish communication.

  • “CODESYS Symbolic”:

    Requirement: The local device is a CODESYS HMI.

    The data is transmitted by means of symbolic monitoring. This requires that symbols are configured in the symbol configuration of the remote PLC application.

    Note: As long as the symbol configuration is not impacted by an application change, you have the advantage that the application in the local device does not have to be updated.

    Hint: Use this communication connection unless there are no resources available in the remote PLC for a symbol configuration.

  • “CODESYS ApplicationV3”:

    The data is transmitted via the CODESYS address protocol. This requires that the address information between the remote PLC and the local device match. Otherwise a connection cannot be established.

    Advantage: A symbol configuration is not required in the remote application.

    Note: For changes to the remote application, the local application has to be updated (for example, the HMI application).

    Hint: Use this communication for embedded or mini PLCs when there are no available resources for the symbol configuration.

  • “OPC UA Server”:

    Data is transferred from an OPC UA server to the local controller via a TCP connection.

“Add”

Opens the “Initialize Data Source - Provider settings” dialog. The contents of the dialog depend on the selected data source type.

The remote PLC should be running and the remote PLC application loaded and started.

Dialog 'Initialize Data Source Wizard - Provider settings' (for 'CODESYS Symbolic')

The settings of this dialog are described in the following chapter: Object 'Data Source' - Tab 'Communication".

The dialog is used to configure the connection initially when you have selected “CODESYS Symbolic” as the data source type. The communication is done by means of symbolic monitoring. The configuration can be modified later in the editor of the data source on the “Communication” tab.

Dialog 'Initialize Data Source Wizard - Provider settings' (for 'CODESYS ApplicationV3')

The settings of this dialog are described in the following chapter: Object 'Data Source' - Tab 'Communication".

The dialog is used to configure the connection initially when you have selected “CODESYS ApplicationV3” as the data source type. The communication is done by means of address monitoring.

Dialog 'Initialize Data Source Wizard - Provider settings' (for 'OPC UA Server')

The settings of this dialog are described in the following chapter: Object 'Data Source' - Tab 'Communication".

The dialog is used to configure the connection initially when you have selected “OPC UA Server” as the data source type. The communication takes place over a TCP connection.

Dialog 'Initialize Data Source Wizard - Browse data items'

The settings of this dialog are described in the following chapter: Object 'Data Source' - Dialog 'Choose Variables'.

Function: You can select the variables for data transmission from the variables of the remote PLC. By clicking “Finish”, the data source is initialized and the data types and variables (data interface) are declared below the folder “DataSources_Objects”. You can modify the settings in the editor of the data source object.

Call: Automatic
