Hi to all,
I have Fault in Siemens ET200S (6es7 151-1aa03-0ab0) from time to time. several of ET200S connect to S7-400 via profibus. occasionally one of the ET200S is not connected and the fault LED are ON in this succession:
1. 8 time the SF LED flashing
2. then 3 time the BF LED flashing in cyclic form
anyone can help my to solve this problem?
Thanking you in advance.
