[?] IO redundancy error during removing and inserting SM

Post by M_Elhaw » Tue Sep 08, 2015 4:20 am

If anyone can help me in this problem

In our safety system S7-400F/H, During removing and inserting signal module in the ET200M rack, the active IM is changed and during this change all rack became offline and I found this a general problem in this system and not a problem of the rack that I was dealing with it.
We are using active bus that support the hot swapping but I don't know why this problem happen?

Thanks
