Hi all..I have a PID instruction that is only called when a valve is open, when the valve closes the rung for the PID is false. However the PID still "remembers: the last value of the CV so the next time the valve is opened my CV starts from there..Is there any way i get the CV to start from 0 every time the rung goes true?
I have tried writing a 0 to the PID.SO (That holds it at 0 for as long as the write takes place but then jumps back to the old CV)
any help would be appreciated
Thanks
Darren
