Hi All,

I'm stumped.

I've a couple of subroutines in a Modicon controller (Quantum, 984LL). I debugged the subroutine and started writing a second routine for a similar task. When I went on-line I noticed that the 1st routine was running but the 2nd routine was labeled "SKIPPED".

On further investigation I noticed that the bottom leg (Subroutine Error) of the JSR block was on. I thought that there might be a problem with the code so I changed the reference to the working routine. Same results.

I searched a bit and couldn't find anything on what causes the bottom leg of the JSR to pass power.

Any ideas?

Thanks,
