Output Parameters
This tab appears as follows:
This tab sets properties that effect the value output from the PID controller, and
also determines the override values.
Max Slew Rate Limits how fast the controlled variable output can
change. This limit is in effect only during soft start.
Soft start begins when the functional block is reset
and it ends when the process variable value reaches
the setpoint. Units are percent output change per
scan interval (set in the Heartbeats tab).
A value of 0 disables slew rate limiting (a value of
100 or greater also disables limiting since the output
can change across the whole range each time the
PID executes).
High Limit/Low Limit Determines the upper and lower limits for the
controlled variable. If the PID tries to set the
controlled variable to a value outside of this range,
the value will be clipped to the specified limit.
