Process industries data model

Cognite’s process industries data model—CogniteProcessIndustries—extends the core data model to cater to specific requirements for the process industries. It’s available from the cdf_idm system space.

Process industries concepts

The extended process industries concepts come with matching containers and views.

CogniteMaintenanceOrder

The CogniteMaintenanceOrder concept has properties to represent maintenance orders. A maintenance order is a request or directive to perform maintenance tasks such as repair, inspection, or servicing of equipment or assets. It’s often called a ‘work order’.

Property	Type	Description
mainAsset	Direct relation to CogniteAsset	The primary asset (functional location) the maintenance order refers to.
type	String	The code for the type of maintenance order, for example, ‘PM01’ for ‘Corrective maintenance’.
status	String	The lifecycle status of the maintenance order, for example, ‘Partially complete’. It’s often derived from the ‘SystemStatus’ field in SAP.
priority	Int64	A number that shows how important this maintenance order is. Lower numbers mean it’s more important, and 0 means it’s the most important.
operations	Reverse direct relation list	Lists the individual work items on the maintenance order. An automatically populated list of operations related to the maintenance order.

The following core features and concepts are also available for this concept: CogniteDescribable, CogniteSourceable, CogniteSchedulable, CogniteActivity

CogniteOperation

The CogniteOperation concept has properties to represent operations, a specific part of the work included in a maintenance order. Often called a “work order item”.

Property	Type	Description
maintenanceOrder	Direct relation to CogniteMaintenanceOrder	The maintenance order the operation is related to.
mainAsset	Direct relation to CogniteAsset	The primary asset (functional location) the operation is related to.
phase	String	The code for the phase the operation belongs to. Each operation belongs to a single phase, for example, ‘Scaffolding’.
status	String	The lifecycle status of the operation, for example, ‘Partially complete’. It’s often derived from the `UserStatus` field in SAP.
sequence	Int64	A number that shows the order in which the operations are performed. Lower numbers mean they happen earlier, and 0 means it’s the first operation.
mainDiscipline	String	The primary skill or resource required to perform the operation, for example, “maintenance technician”.
numberOfMainDiscipline	Int64	The number of resources required to perform the operation, for example, the number of required maintenance technicians.
personHours	Float64	The number of hours required to perform the maintenance operation. The duration is calculated by dividing the `personHours` by the `numberOfMainDiscipline`.

The following core features and concepts are also available for this concept: CogniteDescribable, CogniteSourceable, CogniteSchedulable, CogniteActivity

CogniteNotification

The CogniteNotification concept has properties to represent maintenance notifications. Notifications are formal records to report maintenance issues, defects, or requests, starting the process for planning and running maintenance activities.

Property	Type	Description
maintenanceOrder	Direct relation to CogniteMaintenanceOrder	The maintenance order that was created from the notification.
asset	Direct relation to CogniteAsset	The asset (functional location) the notification is related to.
type	String	The code for the notification type, for example, “M1” for “Maintenance request”.
status	String	The current lifecycle status of the notification, for example, “order created”.
priority	Int64	A number that shows how important the notification is. Lower numbers mean it’s more important, and 0 means it’s the most important.
priorityDescription	String	Describes the priority of the notification.

The following core features and concepts are also available for this concept: CogniteDescribable, CogniteSourceable, CogniteSchedulable
