• Create a "Standard project" and select CODESYS Control Win V3 as the device.
  • Define the target system by means of the Network scan.



  • Open the Library Manager and add the following library:
    VisuUtils



  • Insert a visualization in the device tree.
    Then the Visualization Manager is inserted with the visu types TargetVisu and WebVisu.
    Delete both of these are add a RemoteTargetvisualization. Then assign the Visualization to it as the start page.
    In addition, a VISU_TASK is also created automatically.



  • Create a new FB named FB_Iteration and implement the VU.IVisualizationClientIteration interface.



    The following methods are created automatically with the FB:
    EndIteration
    HandleClient
    StartIteration



  • Adapt the FB_Iteration function block as follows:

    Declaration

    FUNCTION_BLOCK FB_Iteration IMPLEMENTS VU.IVisualizationClientIteration
VAR_INPUT
END_VAR
VAR_OUTPUT
END_VAR
VAR
	sRtvName1 : STRING;
END_VAR

  • Adapt the HandleClient method as follows:

    Declaration

    (* This method will be called for each client that is currently within the list
 of active visualization clients.

 .. note:: Please remark that this method will be called from VISU_TASK*)
METHOD HandleClient
VAR_INPUT
    (* The object representing the according client. Will not be 0.*)
    itfClient    : VU.IVisualizationClient;
END_VAR

    Implementation

    IF itfClient.ClientType = VU.VisuClientType.RemoteTargetVisualization THEN
    sRtvName1 := itfClient.GetClientName();
END_IF


  • Adapt the POU PLC_PRG as follows:

    Declaration

    VAR
    fbIteration			: FB_Iteration;
    fbIterateClients	: VU.FbIterateClients;
END_VAR

    Implementation

    fbIterateClients(xExecute:=TRUE, itfClientFilter:=VU.Globals.AllClients, itfIterationCallback:=fbIteration);
IF fbIterateClients.xDone THEN
    fbIterateClients(xExecute:=FALSE, itfClientFilter:=VU.Globals.AllClients, itfIterationCallback:=fbIteration);
END_IF


  • Load the project to the controller and start it.



  • Open the targetvisuremote.cfg file and add the following entries to the CmpVisuHandlerRemote section:

    [CmpVisuHandlerRemote]
    VisuClient.Name=CodesysRemoteClient1

  • After the remote target visu is started, the specified name is shown in the project:
