Machinery Basic Building Blocks

This building block provides a base structure for monitoring information of a MachineryItem. In Figure 24, the MonitoringType is shown. It provides some sub-structures for grouping different monitoring information. Vendors or companion specifications may add additional sub-structures on the different levels of this building block. The Status Object shall reference the MachineryItemState and OperationMode AddIns, if they are provided by the MachineryItem. The Health of the MachineryItem may be represented by the 2:IDeviceHealthType Interface defined in OPC 10000-100.

Figure 24 – MonitoringType

The building block can be used in parallel to other structures of the MachineryItem or as the main structure of the MachineryItem. In Figure 25 three different examples are shown. X:Machine1 only reference the Monitoring Object under MachineryBuildingBlocks, X:Machine2 has some additional structuring referencing the Monitoring Object in addition, and X:Machine3 references the Monitoring Object also directly to provide it as additional top-level entry point. It is recommended to provide this top-level entry point.

Figure 25 – Usage as Monitoring Entry Point

When the building block is used in combination with the MachineryItemState (see 12) or MachineryOperationMode (see 13), they should be combined as shown in Figure 26. The MachineryItemState and MachineryOperationMode should be referenced as building block from the MachineryBuildingBlocks Object, and in addition, from the Status Object of the Monitoring building block.

Figure 26 – Combination of MachineryItemState, MachineryOperationMode and Monitoring

In B.4, some more detailed examples are given on how to use this building block.

16.2 MonitoringType

The MonitoringType provides entry points for monitoring a MachineryItem and is formally defined in Table 40.
