Multiple Exit Conditions

[condonagon]

Hello!
I am currently attempting to program a BCS-462 in a new nano brewery. I am very new to this stuff, but I am figuring some things out. In our brewery we will be running two mash's side by side, followed by two boils side by side. I want to program the BCS so that both mash's are in the same process. The problem I ran into was with the exit conditions. When I set two exits, (each mash tun reaching temp) if one mash tun is a few degrees behind, it pushes ahead because the first condition had been met. Is there a way to set it up so that both heat independently, but wont move to the next state until BOTH conditions are met? I have it set up now with each mash on a different process, but would prefer if they were both together.

Thanks for your help!

Technically, you could do it as one process, but you would need multiple states. Since you can't do a logical AND between exit conditions, you'd need your initial state where both are heating, then you'd need another state where Mash #1 is at temp but Mash #2 is still heating plus a 3rd state where Mash #2 is at temp, but Mash #1 is still heating. You would need 3 states to do it. Honestly, I really think 2 processes would be better. Will you always be doing 2 mashes and 2 boils simultaneously? Might it be better if they were staggered by some time to allow you to do mash-in, hop additions, etc. for each batch? Even cooling or hose switching could benefit from a few minutes of staggered time between the two.
