Controller Enable
Options
• None
• Binary inputs
• Limit switches
• Fieldbus variables
Factory setting
None
In connection with the DIO module, you can select a
binary input signal, e.g. from an inductive proximity
switch, as a source for enabling the controller.
Setup Level
Options
• Standard
• Advanced
Factory setting
Standard
The Setup Level changes the number of parameters that
can be configured.
If you choose "Standard" the other controller parameters
are active nevertheless. The system uses the factory
settings which usually suffice in most cases.
Process type
Options
• Inline
• Batch
Factory setting
Inline
Decide what type of process best describes your
particular process (see the explanation below).
Batch process
The medium is in a closed system.
The task of the control system is to dose in such a way that the measured value (controlled variable) changes from its
start value to its target value. No more dosing is needed once the setpoint has been reached and the system is stable. If
the target value is overshot, a two-sided control system can compensate for this.
In the case of 2-sided batch control systems, a neutral zone is used/configured to suppress oscillations around the
setpoint.
inline process
In an in-line process, the control system works with the medium flowing by in the process. Here, the controller has the
task of using the manipulated variable to set a mixture ratio between the medium and dosing agent such that the
resulting measured variable corresponds to the setpoint. The properties and volume of the medium flow can change at
any time and the controller has to react to these changes on a continuous basis. If the flow rate and medium remain
constant, the manipulated variable can also assume a fixed value once the process has settled. Since the control process
is never "finished" here, this type of control is also referred to as continuous control.
A mixture of both process types can often be found in practice: the semi-batch process. Depending on the ratio
between the flow and the container volume, this arrangement behaves either like a batch process or an in-line
process.
