We are currently trying to set up an OPC connection from Plant Simulation 13.1 to a Siemens S7-300 plc using a 32-bit Siemens OPC server on another pc.
We managed to setup the connection through the OPCUAInterface and were able to read data from the OPC server. However, when trying to write to the OPC server using the setItemValue method, the following error appears:
Error message when trying to write to the OPC server using the setItemValue method
The Items and Group1 look like this:
OPCUAInterface : ItemsOPCUAInterface : Group1
Additionally, we noticed a likely bug when opening the 'Show Item Values' window:
Bug in Show Item Values
As can be seen, some of the parameters defined in the 'items' table were not written to the 'Show Item Values' table correctly.
We are certain write access is enabled on the variabe we were able to read since we were able to write to it from a test client on the machine on which Plant Simulation 13.1 is installed.
Does anyone have a clue as to where this error might come from?
