Hello, I have in a system a X20SLX542 Safety and an X20CP0411 PLC. I did not found a hardware limit resources that excludes X20Cp0411 but I noticed that If i start the MappSafety i kill the plc (it gets in the service mode with memory violation). I tested the same software with an X20CP0484-1 PLC …

Looks like it is missing the application because it is not yet downloaded. Remember to use Remote Control for that (NOT SafePLC dialog box because that won’t work until SLX is running correctly!)

See this post for trouble shooting in general.

I don’t know about X20CP0411 but I’d expect some logger messages which could provide some more details…
