Fx2N-32MT low battery

[glavanov]

Hello all,

I was asked to visit a remote location facility with non working machine equipped with Fx2N-32MT PLC.

No much info on the problem, but from what i know, the battery is gone and the program wont run.

So i guess, that the program in ram is gone. Not much familiar with Fx2N series...

No memory cassette installed under the front cover and no program backup of any form.

What are my options here?

you'll have to reprogram the PLC. unless you have a backup of the program

[glavanov]

So if can get the program from the manufacturer, replace the battery with new one and load the program with GX W2 should work until the battery dies again, right?

[Gambit]

It should. But maybe also some values need to be entered but the manufacturer of the machine should know.

Thank you Gambit! :)

Where did you have this issue?  I literally had the same issue with the same model PLC yesterday.

Program ended up being corrupted.   It even claimed that the T76 was really X5 when using Find Device.

I'll be on site next week, but they send me photos of the PLC and the battery was teared from the wires and missing. I assume intentionally.

I am facing 100% program loss.

Well be sure to remember your programming cord!
