Intermediate Asset Model

Intermediate asset model leverages both Tagname Dictionary (Historian API) and MES Efficiency (MES API) parts and their capabilities of configuring and hosting asset model information.

For more information, see the Manage the efficiency model section in the AVEVA Insight Help.

Scenario

Scope of this scenario is to define 3 dimensions and 1 measure calculation such as:

• Asset dimension reflects all Asset and Plant available as part of the Equipment Efficiency Model.

• Batch dimension as type of Time Defining Dimension reflects all batches that have been operated against existing assets. This dimension returns all batches (batch ID, Start Time, End Time, etc.) per key fields such as Asset and Plant.

• UtilizationEvent dimension as type of Time Defining Dimension reflects all utilization events and their reason that assets have been exposed to. This dimension returns all utilization event (Event ID, Start Time, End Time, etc.) per key fields such as Asset and Plant.

• Power measure’s calculation computes the energy spent by the context of Asset, Plant, Batch, and UtilizationEvent.

The Asset dimension is populated by retrieving all equipment and location (hierarchy) from the Equipment Efficiency Model (MES API).

The Batch dimension retrieves all tagnames matching the criteria BIGateway_Dimension eq ‘Batch’ and subsequently returns all historical events associated to this tag list.

The UtilizationEvent dimension retrieves all utilization events (MES API).

The Power calculation retrieves all tagnames matching the criteria BIGateway_MeasureCalculation eq ‘Power’ and subsequently returns aggregated historical data associated to per requested time slice.

Configuring Tagname Extended Property

Here is an example of JSON file for creating Tagname Extended Properties leveraging Intermediate asset model concept.

Sample:

{

"metadata": [

{

"TagName": "Asset0001.Batch",

"BIGateway_Asset": {"DataType":"String", "Value":"Asset0001"},

"BIGateway_Dimension": {"DataType":"String", "Value":"Batch"},

"BIGateway_MeasureCalculation": {"DataType":"String", "Value":""}

},

{

"TagName": "Asset0001.Power",

"BIGateway_Asset": {"DataType":"String", "Value":"Asset0001"},

"BIGateway_Dimension": {"DataType":"String", "Value":""},

"BIGateway_MeasureCalculation": {"DataType":"String", "Value":"Power"}

}

]

}
