Mitsubishi A series query

Hello,

I've been fooling around with a HMI lately (Mitsubishi 940GOT). And have an application where I need to adjust a timer value in the plc (Mitsubishi A1S). I have been able to figure this out through the numerical input function on the HMI, but when the power is shut off and returned it resets my data register to 0 (which is undesirable). I have not been able to find a battery back latched register. So I figure most of you more experienced guru's could give me a method that will work. Thanks.

You will find the settings for latched registers under /parameters/-devices.

The default is no latched registers. You can alter this to 'all' or however many you wish to be latched
