Dear all, I came across, one of the S7 400 PLCs (NOT H TYPE) with CPU type 6ES7 414-2XG04-0AB0 with HW ver 2 and FW ver 4.1.0 and during fault all LEDs were blinking initally and when CPU kept in STOP then to RUN, Stop is lit permanenly with EXTF ON and on CP Fault1 and on connected ET200 M modules BF1 fault. Diagnostic buffer is attached. After backup downloading operation normalised, but I wish to know the reasons. It occured on 2-7-10 with event 51 of the attached diagnostic buffer.

If your all LEDs were blinking, then you might have to upgrade your firmware Check Operating System Updates for S7-414-CPUs For Latest Firmware Upgrade Regards, Devesh |
