Description
Defines the minimum time it takes for the setpoint to decrease
from 100% to 0%.
Setpoint decrease time.
Freezes, or defines a source that can be used to freeze, the
setpoint of the process PID controller. This feature is useful
when the reference is based on a process feedback
connected to an analog input, and the sensor must be
serviced without stopping the process.
1 = Process PID controller setpoint frozen
