8.1 Technology controller
Commissioning with STARTER
The "technology controller" function module can be activated via the commissioning wizard.
You can check the actual configuration in parameter r0108.16.
Application example: 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 on TB30) 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 Board 30 (TB30) is used.
