7.7 FeederType
The FeederType represents a device that transports material in an uncontrolled or controlled way. In the second case, the Feeder acts as a dosing unit. A feeder transports the material to a defined destination. This can be directly a barrel zone, but also another feeder which collects materials from several feeders above.

7.7.1 Name
The Name Property gives the name of the feeder/dosing unit and is used as reference in the Target. Unique within the extruder
7.7.2 Description
The Description Property gives a description of the feeder/dosing unit.
7.7.3 IsPresent
The IsPresent Property provides information if the feeder/dosing unit is physically installed and connected.
7.7.4 IsActive
The IsActive Property provides information if the fedder/dosing unit is active in the current production.
7.7.5 Target
The Target Property provides information to where the feeder brings the material. This can be a barrel zone (ExtrusionTemperatureZone) but also another feeder. The value of the Target Property shall be equal to the value of the Id Property of the relevant ExtrusionTemperatureZone or feeder.
NOTE: The Id Property is modelled inside the MeasuringDeviceType which is the basis for all zones.
7.7.6 IsControlled
The IsControlled Property provides information, if the feeder is controlled (by a valve, screw, …) or not (material just falls through by gravity).
7.7.7 Mode
The Mode Property provides information, how the throughput of the feeder is controlled.
| Name | Value | Description |
| ONLY_CONVEYING | 0 | The throughput is not controlled. The feeder only transports the material (e.g. by screw, conveyor belt) or the material is only falling through a feed opening |
| OTHER | 1 | Throughput is controlled, but in another mode than these below |
| GRAVIMETRIC | 2 | The throughput is controlled by a gravimetric dosing system. |
| VOLUMETRIC | 3 | The throughput is controlled by a volumetric dosing system. |
| LIQUID | 4 | The throughput of liquid material is controlled by a pump. |
| BATCH | 5 | The throughput is controlled by a batch dosing system. Note In this case, each material has an own feeder although there is only one physical system. |
7.7.8 Throughput
Current throughput of the feeder/dosing unit in mass per time (e.g. kg/h). Although the modelling rule for this node is optional to cover also pure feeders, it is mandatory for dosing units. The MonitoredParameterType is defined in OPC 40083.
