Re: [foxboro] Some things to talk about

How about adding an Integral deadband to PIDA blocks, so that when the
process is within the deadband, the Integral action is turned off. We
have many loops within our plant where the controller cannot control
right on setpoint, so, there is a constant small swing around the
setpoint, with the controller output having a sawtooth pattern. An
Integral deadband would help eliminate that.
