Beckhoff BC-9000 nonvolatile (remanent) variables working ex

Post by Velund » 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?

you can define it in system manager or ks2000, or may you use FUNCTION_BLOCK Persistent_Data in tcsystembc.... :-) lg peter
