Configuration
Make the following decisions when configuring a controller:
1.
What type of process can your process be assigned to?
-->Process type
2.
Should it be possible to influence the measured variable (controlled variable) in one
direction or in both directions?
One-sided or two-sided controller, -->Controller type
3.
What should be the controlled variable (sensor, measured value)? -->Controlled variable
4.
Do you have a disturbance variable that should be active at the controller output?
-->Disturbance variable
5.
Define the parameters for the controller:
– Setpoint, -->Setpoint
– Neutral zone, -->Xn
– Proportional band, -->Xp
– Integral action time (I-value), -->Tn
– Derivative action time (D-value), -->Tv
6.
What should the controller do in the event of a hold (measured error, sensor replacement,
cleaning etc.)?
– Pause or continue with dosing?
– At the end of a hold, continue or restart the control loop (affects I-value)?
7.
How should the actuator be triggered?
– Assign "U" to the output for an actuator which can increase the measured value.
– Assign "Unipolar-" to the output for an actuator which can decrease the measured value.
– Select "Bipolar" if you wish to output the manipulated variable via one current output only
(split range).
8.
Configure the outputs and switch on the controller.
