ISA-95 Equipment Model

The ANSI/ISA-95 international standard is used globally across all industrial sectors to develop automated interfaces between enterprise and control systems. The standard provides a consistent terminology for information and operations models that can be used to describe information flows for batch and continuous processes.

The ISA-95 Equipment model allows you to create an equipment model that matches the hierarchy model described in the ISA-95 standard and map measurements associated with assets to items in the I/O model. All the object classes that can be created in the ISA-95 Equipment model have an equivalent in the ISA-95 hierarchy model and demonstrate the same object linkages allowed in the standard. For example the Enterprise object is the highest in the model hierarchy and can be made up of child Site objects. This continues all the way down the hierarchical model to Control Modules.

All objects in the Equipment model can be given asset codes that match those used in the ERP system to identify the asset.

Batch Tracking

The ISA-95 equipment model objects can be used and linked to Batch Record creation in accordance with the ISA-88 standard. The Batch Tracker object can be linked to equipment objects in the ISA-95 Equipment model as part of the Production Tracking features of system:inmation.

Autonomous Site Operation - Local Cores

Objects in the ISA-95 Equipment Model can be linked to Local Core objects as part of the Autonomous Site Operation functionality. This couples the S95 Site or S95 Area object to that component, meaning Code Execution is done in the chosen Core and is only visible from the context of that component.

If the Code Execution Component property is configured on a specific object, an association indicator will be shown next to the object in the model panel. Hovering over this indicator will display the path of the object assigned to the Code Execution Component property.
