Micro850 Program Loss - PLCS.net

Hi,
I have a Micro850 that looses its program any time the power is cycled. Any suggestions?
Thank you in advance,
Mike

Hi Mike and welcome to PLCTalk

How is your ground? other than a grounding issue I can think of anything that would cause it... You maybe able to use a 2080-SDMEMRTC-SC and load the program to that or install a UPS and keep it powered up but I think if I had to go that far I would just replace the processor

Thank you! I have been on Rockwell chat for 2 hours and the solution is to replace the 850.
