Hi there, I am accustomed to working with Logix 500 but have a program modification I need to do on a CompactLogix....
I created a timer...no problem.....created a rung with the timer timing bit as an XIC controlling an output...no problem.
In another routine, (about 3 routines down in the routine list) (well, I guess these are all subroutines but they are not conditional,) I am trying to create an XIO instruction with the same Timer Timing bit but when I hover over the bit, its showing as unspecified, and in the "logic verify" results, it says the bit can't be referenced.
The weird thing is, I was able to create the XIO bit with no issues in the same ladder as the timer (a couple rungs below it)..then copied/pasted the instruction into the other ladder and that's where it shows as "bad"....what am I doing wrong?
If in RSLogix 5000 you can't do what I want, how should I get around it?
Thank you.
