I have problems loading the PLC program into the internal CPU flash memory, particularly in the middle of the procedure Concept tells me that a communication failure occured.

Has anyone a solution or advice about it?

 

If you have non-A version (140 CPU43412), then make sure that you have the latest IEC firmware loaded, nowadays latest is 1.21.

If you have A version (140 CPU43412 A), then make sure that you have the latest IEC firmware loaded, nowadays latest is 1.30.

If these still don't help, contact your nearest Schneider Sales office to ask a replacement for your CPU.

Good luck.

 

Hello,
Eclipse shows this as latest firmware for 140CPUX341XA Flash Exec v1.29 04/05 - please advise where to find 1.30.

Regards,
