12.6.5 Control loop monitoring
Control loop monitoring monitors the control response during startup of a plant and in the event
of a setpoint step by analyzing the change of the actual value during an output level change.
An alarm is issued if the actual value does not respond according to the specifications.
The alarm signal is available from the digital selector and can be processed further at any time.
