Write/Read Safety Signals over OPC UA

[francesko95]

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.

Which version of Visual Componets are you using? What kind fo license do you have?
I've just find out about Visual Components, and I'm looking for some kind of demo version to try it out, but I couldn't find one yet.
Any comment would be appreciated.

Thanks!
