Hi guys,
I think, you know this issue... the last power module at the ET200S rack (sometimes) indicates system fault (SF diode) but everything is OK. Till now, nobody explained me this "feature". Is it the terminal module (resistors) which causes this? I was googling an hour, but didnt find anything.o_O
Can you please give me as answer ?
Thanks.
J.
