very easy rslogix500 question, I think

[unsaint32]

I'm embarrassed in advance. It's been a while I touched RSLogix 500. Why am I not getting the internal coil (B3:100/0) come on when the rung is true?

 

[mmedina]

it is probably being used somewhere else in the program
do a "find all" for that bit

is ladder file 12 being called?

No, there is only one OTE, which is the one I circled red in the previous pic.

Ok, what about the word B3:100 - is that being used/cleared/set as a whole word, rather than individual bits?

That's it! No it's not. I always forget that. Thanks.

no problem....another Monday morning head scratching session ended...!

If this is a new routine you've added, are you calling subroutine 12, with a JSR? Looking at that rung, and the other rung where the counter is on but one input condition is false, I'm positive you are not scanning that Ladder 12.

*edit* Sorry - didn't read the post above where you solved it.

You are right. JohnCalderwood had pointed me to that mistake. Thanks.
