All this unit will do is automate blowing the boiler tubes and stack, which we are currently doing manually due to the failure of the old Toshiba EX box. Our mechanical services contractor won't even talk to us about it, it's so old...
I haven't started any programming yet, between the forty-eleven other things on my plate and wanting to get a little more pre-planning done.
When I was playing with dBase, I learned a hard lesson about the dangers of building a program piecemeal and then going back and patching it until it worked.

I am proud that the program worked for you. I thought that you might go with the simpler version. You have proved again what I have argued here for years: Lancie1's PLC Rule #1 states that simplicity and more rungs in a PLC program is often more desirable than complexity and fewer rungs.

extra rungs don't form spagetti code
