BCS Programming State Question
 
Hey guys,
Could someone give me a hand with the programming of a state?

In a 40 minute period, I would like my pump to come on 3 times for 2 mins to circulate water in my HLT.

How would I set up the program to do this?

Any help would be appreciated,
Thanks in advance!

Im still very new to this as well so take it for what its worth,

if you have an available process you could use you hlt process to spawn a seperate process specifically dedicated to this once you hit desired temp.

state 0 would start timer0, exit condition would be when timer 0 >=11
on exit cond goto state 1

state 1 would be pump control on, timer enable continue from previous state
exit condition would be when timer 0>-13
on exit cond goto state 2



then you would basically repeat that two more times,

not 100% sure but that would be my first try..

kosmokramer is on the right track, switching states by the timer will work.

HLT Heat process starts Pump process at beginning of cycle.

Pump process starts in state 0 with pump off and exits to state 1 at 8 minutes.
Pump process state 1 has pump on. Exits state 1 to state 0 at 2 minutes.

HLT Heat process stops Pump process at end of cycle.

pump then runs between 10 & 12 minute, 22 & 24 minute and 34 & 36 minute timings.

Thanks for the heads up, I'll take a look at trying to program these states this week and possibly brew this weekend.
