Memory A1S

3 posts in this topic

Hello, I have a question about the memory of A1S. Is there a way to hold the data from counters, timers and other data after a power failure. The A1S has a real time clock on board. So theoretic is should be possible if you ask me. But i cant find the right way to do it. I'm new on this forum. And maybe even with plc. But i know how to program. It would be stupid if a my plc cant remember data after power failure (the internal battery is on full power) Hope somebody can help me, or can confirm that it is isn't possible to do what i want. Thanks, Wesley

In GX Developer, select PLC parameters, then on the Device tab set the ranges to be battery backed.
