6 OPC 40082-4 Information Model overview

The task of a dosing system is to bring material into the production process. This can be done in a continuous or discontinuous manner (batch) or a combination of both (see Figure 1 for an example). The material can be gravity fed or controlled and combined with an optional starve feeder (e.g. for extrusion).

Figure 1 – Dosing System example

The information model defined in this specification models the complex structure of a dosing system as follows:

The top level ObjectType DosingSystemType contains the objects for machine identification, machine state and configuration of the complete dosing system. The individual components are modelled in the OperationType with all properties required to monitor and control the operation of the system.
