I forgot to mention that I've also done that. I've went as far as to trying all 5 or so of my spare outputs and each has the same flickering issue though they aren't found anywhere else in the ladder logic.

I have a machine that we added an input to. During the addition of the new input, our maintenance team shorted out an output on the main controller. I thought it wasn't a huge deal as we have another output card with spare outputs. I wired the output to the other card and in my program I just added a line that said -|Local:1:O.Data.8|-----(Local:3:O.Data.4). I was under the impression that this would energize O:3/4 when O:1/8 would normal energize. The output is controlling a valve and the valve does work off of O:3/4 when O:1/8 is running, but it flickers sporadically the whole time. So far I've tried latching the output and taking the load off the output card and nothing has stopped the output from flickering. Any guidance is appreciated!
