Hi everybody
We have been having repeating emergency stops on our crane due to passivation of the F-module(PROFI safe V2, safety-related).
Some of the communication between modules are wireless.
CPU 315F-2 PN/DP :6ES7 315-2FH10-0AB0/V2.3
PROFINET IO device interface module IM 151-3 PN HF (ERTEC200) for ET 200S electronic module, supports packing :6ES7 151-3BA20-0AB0
Digital output module DO 4xDC24V/2A, PROFI safe V2, safety-related :6ES7 138-4FB02-0AB0
Step7-V5.4 and I am using S7 Distributed Safety, version V5.4+SP5
1)I have tried to change the read back time from 50 to 200ms in the Digital output module DO 4xDC24V/2A, PROFI safe.
2)Save and compile.
3)Download to module.
When I changed to online mode there is a mark on the DO module, message: faulty module.
I also looked at Collective signature off the safety program it was different online/offline.
It seems that the Fail-safe programming is blocking the restart of our CPU?
The only way I could make the machinery run again was to install a complete backup of the entire program. And change the read back time to 50ms again.
What am I doing wrong?
I need to change the read back time.
I would appreciate if somebody can replay to me on this issue
Thanks in advance
