hi all

i have test software redundancy with two cpu s7-300 315-2dp and redundancy link with profibus cp on simulation

but it goes wrong and fb 101 give me error 8019 on ob35 first cycle and 8013 or 8015 on end of ob 35 cycle.

my question is software redundancy can run on simulation or not ????

i saw some youtube clips that run software redundancy on simulation..

thanks for your help ...

Hello,

If you read our forum, opinions differ - on this topic.

However, I saw my colleagues test the software redundancy of the S7-300 controllers.

Check out the topic below:

Possible to test H/R redundancy with S7 simulation Software.

and read FAQ:

How do you simulate communication between two CPU modules?

I am sure (True, I did not check it personally) that this can be done, the main thing is to configure everything correctly

Try to do everything as in the example, and then test the redundancy)
