Logo Plc - Time To Hold The Program After Power Fail

hi all

We are using LOGO PLC in some of our plants. Can any one tell me if the power fails, how long it can hold the program, without the memory card inserted in it.

Sanjay,

You'd get more response if you post in the live question and answer section.

But to answer your question, I've hade several logo that power would be shut down to them for weeks, the program is still there but I would have to reset the date and clock on them.

Hope this helps

I have gad some (same unit, different brand) hold the program for weeks, but a couple did drop program after a couple of days. It sems most a goood for a month or more.

Your personal results may vary.

Highway mileage will be higher.
