s7 300 313c

Hi, I'm new here & fairy new to s7 problem solving. My system is a s7 300 313c connected to multiple Lenze 9300 servo's & vector drives, on our op7 we have got a 'ram memory failure' error after experiencing a general power failure & reboot of system. My initial thought was the s7 backup battery was faulty, Siemans informed us that there is no backup battery. I noticed that someone remarked about a battery failure. Our s7 has a MMC card, please help! thanx Edited 5 Jul 2009 by robertsafrica

Hi. But in the simatic manager query nodes accessible something anserw. if nobody anserw, and the led blink in the same time maybe you have problem with MMC before consulting Here Only if you are sure the MMC is Fault you can try to formatted it. ....I don't remenber about 'ram memory failure' never see it.... bye

Thanx Gixramones, this info has helped, confirms my initial diagnosis. We need to get a 'Prommer' to format & reprogram MMC. bye
