I can't connect to Concept PLC Sim32.
Error for Concept 2.5 SR2 and 2.5 SR2:
Unknown Modbus exception code. Error ID: OL9-21504.
Help me, please!
 
One possible explanation for this error is a conflict between Concept and the v6.0 Ethernet MBX driver. Uninstalling the v6.0 Ethernet MBX driver and rebooting the PC will correct the issue.
