Tracking
In tracking mode, the PID block output is set directly to the value of parameter
40.50 (or 41.50 ). The internal I term of the PID controller is set so that no transient
is allowed to pass on to the output, so when the tracking mode is left, normal
process control operation can be resumed without a significant bump.
