Emulation PLC with OPC UA - Problem with connection

Hello,

I have a problem with connect FlexSim with siemens PLC S7-1500 via OPC UA. I am using FlexSim 20.1. I added emulation in toolbox in FlexSim model. I can see OPC server on PLC, i see whole data structure on PLC. But when i add this connection, i cannot start FlexSim simulation. I get exceptions in System Console:

"

exception: Exception Caught in ObjectFunction240__project_library_FlexSimEventHandler_behaviour_eventfunctions_OnReset object: /Tools/Emulation class: /Tools/Emulation

exception: Exception caught in TreeNode::receivemessage()

exception: Executive::__reset()

exception: int Executive::reset()

exception: reset

"

When i delete this connection, i can start simulation without errors. Have you any ideas where is the issue?

Best regards

Software Version:

FlexSim 20.1.2

Hi @Przemysław BS, external connection bugs are almost impossible for us to debug without access to the hardware. The best we could do is point you to the documentation on OPC UA connections:
