Hello,
I have a function block that uses a PID control to operate a heater (actually a number of them). The engineer who wrote this is gone and I have no experience with this particular utility. The voltage on the heater ramps up from zero over a number of seconds (about 10 - 30 seconds). We need to increase this time but I don't know which variable controls the time. Would anyone be able to guide me in the right direction? A PDF of the function block is attached.
Thanks for the help,
Rath
