Commissioning

The commissioning window helps you commission the PID controller. You can monitor the
values for the setpoint, process value and the output values for heating and cooling along
the time axis in the trend view. The following functions are supported in the commissioning
window:
● Controller pretuning
● Controller fine tuning
Use fine tuning for fine adjustments to the PID parameters.
● Monitoring the current closed-loop control in the trend view
● Testing the controlled system by specifying a manual PID output value and a substitute
setpoint
● Saving the actual values of the PID parameters to an offline project.
All functions require an online connection to the CPU.
The online connection to the CPU is established, if it does not exist already, and operation of
the commissioning window is enabled by means of the "Monitor all"
the trend view.
Operation of the trend view
● Select the desired sampling time in the "Sampling time" drop-down list.
All the values of the trend view are updated in the selected sampling time.

Value recording is started. The current values for the setpoint, process value and output
values for heating and cooling are entered in the trend view.
● Click the "Stop" icon if you want to end the trend view.
The values recorded in the trend view can continue to be analyzed.
