Program code block stops after runtime edit

[davidbgtx]

I have a program code block (Line_Run)that after performing a Runtime Edit, randomly stops. In attached pics you can see that the enable rung is true and the exit rung is false. I have to switch PLC to program mode then back to run to get the code block to run again. Please help

Noticed that PLC was 1.41 version. I updatre to 2.02 and 3.07. Will see if that helps any. Was this a known bug in 1.41?

No bug that I'm aware of.

Probably not a relevant point, but the enable state of the RUN has no effect on a running block. RUN is edge triggered, so it starts a block on input edge, then does nothing.

I would like to see you use the EXIT condition to drive a counter in code that always runs, to confirm that it isn't firing.

in the main or Line_Run code block?

Main. Just drive it with the same input condition as the EXIT.

Yeah, edge triggered, forgot all about that. That's my problem, I've "or"ed the run so it can't restart once I exited. Back to the drawing board, thanks for your help.

Redid the rung for run program Line_Run, and that fixed the issue. Thanks again.
