  1. GX Works3: Device comment edits won't "take".

    check the manual to see if this range is an internal assigned bit. example Normally OFF  normally OFF,  timer 1sec , 0.1 sec., etc    
  2. line true M bit coil not ON

    Thanks Luke i'll try and figure out HMIs and other PLC,  unfortunately no mapping between hardware supplied, might be difficult to get a starting point I did just find some M0Z0 instructions thinking this may be a little above my pay grade.....
  3. line true M bit coil not ON

    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!
