Are you meaning OEM279    Reverse Run?
What exactly are you trying to do as I think you need to feedhold before you can reverse, then again its something I never use so could be wrong.

Hi
Im building a wire edm.
the electronic feedback unit on the machine monitors the burn cycle and requests the drive software to pause and then reverse a short way before continuing on with the job.
This is represented by a single line giving a a high or low logic level to the drive software.
Pause alone is not enough a small amount of backing of is reqd.

I am not sure how easy that would be to achieve. I am no expert at VB so probably best left to others but I would think you would have to use a macropump and have it looking at the input and  the Run LED for its backup and then Input and Single block LED for its restart. Reason you will want it to look at the LEDs is you will only want things acting on the input whilst you are actually running code.

I will have a messs around and see if I can come up with something but as said my VB skills are crap.

This in the macropump seems to work fine if you are looking at Input1 for your signal.
