Re: [Emc-users] integrating a spindle fault signal in a modular way?

Ugh... I realized I was trying to reply on this thread from a different email account and the mails didn't come through. In any case, I ended up solving this with a classicladder program for estop and a separate one to delay the spindle fault estop signal until one second after the machine was

Now I find myself with two ladder logic programs and needing to add a new way to get to the estop state. I don't seem to be able to determine a clean, modular way to do that. I can run the two classicladder programs in one file and hook up the inputs and outputs as necessary of course, and
