Can't get MOV, COP Instructions to work at all!

I am trying to move N37:0 to N32:101 and cannot get it to work. It has to be something easy. I have a micrologix 1500. I can manually change the datafile value in N32:101 to the desired result but the MOV operation will not do it.

I am very frustrated. There is nothing from the RSLogix 500 software that is telling me that it shouldn't work.

When you say it is not working, what do you mean. It is MOV and then the source and destination......

But (from experience) are you online?, did you test edits and assemble edits? Is something else also writing to N32:101 from somewhere else so that your answer gets rewritten?

I have spend too many times scratching my head only to do a "Doooh" as I find out I was offline the whole time.

It has been a while since I used a SLC500 but the instruction works..........it is usually a loose not behind the keyboard that is the issue ; )P

Also make sure that the LAD routine is enabled. Don't know how many times I have seen that one. Put some instructions into a LAD that is not scanned, and then wonder why the instructions don't do what they are supposed to.

Good Point, I have also had this self induced issue of "No Jump to
Subroutine" .......
