Ah nuts, and here I thought I was so clever

Guess the moral of the story is read the link before you correct people

Thanks to Altenbach for posting the rest of the "bad aspects" in the Rube Goldberg section 😉

That one hurts to look at.

If the heater bit is equal to the old value of the heater bit then the the old heater value is set equal to the value of the heater bit, else set it equal to the heater bit.

I think you need to specify which heater bit you are talking about. I could not even figure out which terminal the "heater local" local belongs to. 😉

For the "output word", we again have the problem of using an indicator as a control...

[JeffOverton]

Which option would you prefer?

LOL, yes. but don't forget to generate an error condition if the two options differ. There might be a government requirement for code redundancy in case of cosmic events. 😄

In that person's defense, that was just a silly example program to demonstrate the subvi-event setup they had.
