Write/Read Safety Signals over OPC UA

Post by francesko95 » Wed Jul 03, 2019 7:08 am

Hello to all,

I am a student from Croatia, and i am working on virtual commissioning. I am using Visual Components and KEPServerEx on my PC and NETtoPLCSim with TIA Portal on the PC of my College. everything is working fine except the Safety Signals. The Virtual PLC can Write safety Signals to OPC UA Server and i can read them, but when i try to send signals to the plc it overwrites them. Is it possible to write safety signals to a opc Server and to the plc or...
I am also using plcsim advance to simulate the plc.

Thanks you.

Hello, I am from Brazil, and also learning about virtual commissioning, I am using NX and trying to communicate with TIA Portal. Could you share KEPServerEX software? Thanks in advance.
