1394 IMC S Class Compact Error

Can someone help me out I'm getting a Setup Data Memory Fault I looked it up and I don't quite understand what's going on. How can the setup values change? I can re-download the program and reset and the fault goes away and then it comes back in a few day so far today I had to reset it 2 times. This never happened in the 7 years this has been in service. I just tried and lock the memory using the key have to see if it happens again. I'm open to any idea's thanks for the help.

Still having the same problem is there a battery that retains the memory in this unit??

Is it an S-Class or a 1394?

It seems (from ancient memory) that there is a battery, much like a PC clock backup battery on one of the main boards in an S-Class...not sure about the 1394.

Are you seeing this error in a terminal window in GML Commander? If so, what version of Commander are you running?

EDIT: See page 856 of the manual in the link above for info about the different types of memory, and how it is backed up and used.

It's a IMC S Class catalog no. 4100-234 and I'm using GML Commander version 4.03

Every time we power down the program is gone.

Alright, I don't have a manual for that hardware, and didn't find anything good at ab.com.

Next opportunity:

Power down, open the door, remove the bracket holding the cards in place and slide them out very carefullly. Look for a watch type battery that looks like what is used in older PCs.

IIRC, it might be on the power supply board, but it has been a long time.

I also recall that there is a memory protect jumper that can be added, but I might be mixing it up with the Creonics units or the 1394. I do know that the Creonics were more prone to problems with the memory protect jumper removed, but don't recall if this is a separate feature on the S-Class or if it was replaced by the keyswitch. If you can find out where that jumper goes, I don't see much harm in adding one.

Here's the manual of this unit. It seems that there is a backup battery for the RAM memory.

I've looked everywhere and can not find a battery anywhere

Do you have a spare? Maybe you should install the spare, and send this one to a repair shop and have them replace the battery/memory.

In chapter 2 I found this text:
(write-protected battery-backed RAM).

So maybe you have to raplace the hole RAM...
