When I see its Attributes, in Retain, the valueNon-Retained is selected. I can't change its value. Please giveme anysuggestion. Attachment retain.JPG (1280 Downloads)

Nothing found as Good other then BAD. When power goesOFF and then ON (in 30s interval), the TimerET value&PT value are same and the Timer output(Q) is ON even if the Timer ET value is 50s while the PT value is 6h10m30s before power goes OFF. I DON'T KNOW, WHY? The link(how can you reduce memory usage with Multi instancing?) describes the way to Multi Instancethen what the use of In-Active Multi Instancein the Timer call options (See the attachement from previous post). Don't forget to tell ifanyone know.

The only way to getthe elapsed time equal to the preset after cycling the power is if the preset time has been reached before powering down..... Its only possible if the Timer hold the elapsed time (means the timer enable input goes to off state from on state) before power off. If the timer is running before power off its NOT work. In that Project, If I0.0 is always on (means its state is high before power off and after power on), then its not work for me.
