Beckhoff BC-9000 nonvolatile (remanent) variables working ex
Posted: Sat Sep 19, 2009 11:24 am
Can someone share some tested example of working with nonvolatile storage in Beckhoff BC series PLC?
All I need is to keep few vars through power-off and allow remote UI to read it out at startup and set them when necessary.
Is there any way other than "shadowing" them in RAM, read at startup and compare on each cycle, with writing on change only?
