Hi

I have a card err light flashing on a M340 plc.
CPU bmx p34 2020.
The memory card is a 8 mb card.

Is somebody can help with that problem?

 

There may be Memory card battery problem, Don't remove both batteries at a time... replace one by one..

Vijay the m340 memory doesn't have any batteries. Its an sd card and the cpu uploads the program on every power up.
