Dear All,

I am using CP-341 ( 6ES7341-1CH02-0AE0 ) and step 7 v5.5. sp4 and I want to configure it as a slave. I have installed parameter assignment tool also. After installing I can see parameter button enabled in my hardware, in properties of CP. But I cannot select modbus slave in protocol selection. Please find attached error screenshot and installed software.

I have tried reinstalling several times. All other drivers are selectable, like ASCII or 3946R. But Modbus slave gives error.

Please give any solution.

Kbv.

Hello Duris_I,

Thanks for reply.

You are right. I had to install Modbus-Slave319.exe also. and now its working.
