Posted 25 May 2011 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 Share this post Link to post Share on other sites
Posted 25 May 2011 In GX Developer, select PLC parameters, then on the Device tab set the ranges to be battery backed. Share this post Link to post Share on other sites
