Commissioning
The "technology controller" function module can be activated by running the commissioning
wizard. Parameter r0108.16 indicates whether the function module has been activated.
Example: Liquid level control
The objective here is to maintain a constant level in the container.
This is carried out by means of a variable-speed pump in conjunction with a sensor for
measuring the level.
The level is determined via an analog input (e.g. AI0 TM31) and sent to the technology
controller. The level setpoint is defined in a fixed setpoint. The resulting controlled variable is
used as the setpoint for the speed controller.
In this example, a Terminal Module (TM31) is used.
