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.
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.
