OPC UA Method call in the PLC restricted to 1 Argument

OPC UA Method call in the PLC restricted to 1 Argument

I found the UA_MethodCall Fb to call a method via OPC UA, but the documentation states that only 1 argument can be used. The method I want to call has 2 input variables and 4 output variables. Is there an update planned for this function block?

Additionally I was wondering if I needed the OPC UA client App to use these FBs or if they work without the App?

With version 1.20 of the PCL app, the CXA_OpcUaClient.UA_MethodCall supports more than one input and output arguments.

The OPC UA client app is also needed, because the PLC client FB's is using functions of the client app.
