3.5 SP Ramp Set Up Group
Introduction
A single setpoint ramp [SPRAMP] can be configured to occur between the
current local setpoint and a final local setpoint over a time interval of from 1 to
255 minutes.
SPRATE lets you configure a specific rate of change for any local setpoint
change.
You can also configure a 12-segment program from a Ramp/Soak profile.
You can start and stop the ramp/program using the RUN/HOLD key.
PV Hot Start is standard and means that at power up, the setpoint is set to the
current PV value and the Ramp or Rate or Program then starts from this value.
