G120 Redundancy: how can setup system architecture and which type of Switch should use?

AutoGen_6024931

Hello mark1507

Thank you for reply, 

It is really bed news. Because Here I cant change from Profinet to Profibus.

But my concern is that it is good that S2 Redundancy in siemens system but there are many other 3rd party devices which do not support S2 Redundancy. It will be good that we have some device that convert S1 protocol to S2 protocol so that we can able to communicate other system also.

Now customer are saying that it is limitation of our system. which left bad impression of Siemens. 

Thank you.

 Hello Autogen_6024931,

Did you managed to solve the problem.?

I have the same problem but with siemens own G120 drives which does not supports System redundancy S2. From the siemens documents it is not recommended to connect S1 devices to PCS7 Redundant system. 

Please suggest me any possible way i have to follow to get communication with G120 drives.

Thankyou in advance.
