Its correct, i use that PLC for many control things, and this failure is cause of the battery. For quickly reparation can use litium batteries CR 1220 instead of MR1220. All this works as long as have a backup the program of plc. For Fatek i recommend save the program in Drive or USB for future repairs.

@@mshahidazeemi3701 Can you be more specific with your question? I didn't get it. What do you want to know? How to upload a program to a plc? or recover the plc program?

[@omargarcialechuga7205]

@@mshahidazeemi3701 if you want to recover the program from the plc, but it marks the error of the flashing light, unfortunately the program was lost. I had this problem a few months ago, and the program was uploaded 10 years ago, fortunately the company I gave service to had a backup of the program.
