desuhardi Posted August 8, 2006 Report Posted August 8, 2006 What is different between 6ES5 955-3LC41 and 6ES5 955-3LC42 ? I use 3LC42 on base unit with S5 CPU, and CPU can't run, stop led was blinking. But if use 3LC41, CPU can run properly. If I use 3LC42 on extension base unit, without CPU, it is okay. All jumpers inside power supply unit are same. Please help if somebody know about this. Thank you Quote
gregoryg Posted August 16, 2006 Report Posted August 16, 2006 (edited) Maybe this would help you... Signals like battery fault (MB-NB), voltage monitoring (BA-EX) can be passed to CPU and as I remember can cause stop of the CPU.
