I am using LM90micro PLC. Lately I observed that it often stops. I presume it has lost the memory. When ever this is switched off, I have to make it to run mode. Can you suggest a remidy please.

The 14-point Series 90 Micro units only have a super cap to back up RAM memory and it can only maintain memory for a few days. The 23 and 28-point units have a battery to backup RAM. If your problem is due to loss of RAM memory you probably need to replace the battery in the larger unit or make sure power is not removed for longer than a few days.
You should check the fault table when you go online with the program. Stoppage could be due to some other fault.
