TT_ZX Posted February 13, 2012 Report Share Posted February 13, 2012 I had a customer ring yesterday with an error on the screen: Stop Mode Fatal Error 003.004.00 No Application It seems that the PLC lost its memory while it was powered up and running. I haven't been backing the program up to flash for various reasons. Has anyone seen this before. I checked the battery and this was ok, not that it should matter because the PLC was powered up the whole time. I have seen PLC's get corrupt memory before but never lose there memory completely. What happens if the memory in the V1040 gets corrupt? Quote Link to comment Share on other sites More sharing options...
