CP341 Freezed with redundant ET200M

Wacky Posts: 60 Rating: (2)	Hi everyone! I have a set of S7-400H with redundant ET200M and 6 CP341. The system was working without problem until the power supply for ET200M and CP341 are disconnected. After re-supply power to ET200M and CP341, 3 CP341 runs normally, but other 3 CP341 get"freeze". No communications any more and no SF LEDs are shown. Does any experts know the solution? Thanks!

Hi Late, Do you have any information about the block? I used P_RCV_BK (v2.2) and P_SND_BK (v2.7) for the communication of CP341s.
