Hello
system is Q06UDEH
GX developer 8116W
Large system 2 PLcs with 60K lines of code between them, SFC ladder,
Issue, all conditions HIGH, coil not ON or visa versa (not all condition ON but coil high) also happen with data comparisons, moves etc.
what i have looked at so far,
-batch monitor confirms HIGH/LOW states
- programs all scanned (all 35 of them)
-no MC control ( some CJ and for NEXT seems unrelated)
-force history is clear - not willing to rest CPU as this is a large press and it is running
-widespread condition throughout the code
- only monitor one window at a time
Q - is there some monitor setting that I haven't found?
over lapping registers
Have gone online with original backup just to make sure something didn't happen with the read.
No way i'm doing an edit when I cant tell whats going on with this.
thanks!
