Omron DM

[khoi]

Hi everyone,

I am a newbie and I was trained that Omron DM is not retained memory and I think it cannot hold data incase power off.

But in fact, I find that DM can hold data if power off even if I remove the battery.

Anybody can explain me more clearly.

Thank you

Hi.

You are right , the DM can retain their contents.

Some words in the DM Area can be saved to the built-in EEPROM backup memory using Auxiliary Area

bits. These words are specifically referred to as the backed up words in the DM Area
