Hi
Whenever I've had to do an overall reset on a S7 PLC its just been a case of turn the key (or hold the switch down), let the light flash twice, then let go and turn the key again, the amber light then flashes rapidly and the entire system has had its memory reset.
However, I've just been using a 315 2-DP and this method didn't clear the memory out. I'm assuming its because of the MMC card that was in it.
How do you do an 'overall' reset when there's an MMC card in the PLC?
Sorry if this is an idiotic question and I know that you can just go 'online' and manually delete the blocks but just wondered if there was another way?
Thanks
