Asset Management

Physical assets represent the real-world structure of your organisation, following the ISA-95 hierarchy. They form the backbone for linking tags and energy data to the right part of your business.

The physical asset hierarchy

Enelyzer follows the ISA-95 (S95) standard structure for modelling business assets. The S95 equipment model defines a hierarchy of logical entities that represent different aspects of production.

Hierarchy Mapping in Enelyzer

• Enterprise

  • Represents an entire company or a division within a company.

  • In Enelyzer: represented as a Facility.

• Site

  • A physical location of a business unit within the company.

  • In Enelyzer: represented as a Building.

• Area

  • A physical location within a Site that encapsulates a certain aspect of production.

  • In Enelyzer: represented by a Building Unit.

• Work Centers

  • Entities below Area, such as Process Cells, Production Units, Production Lines, and Storage Zones.

  • Groupings of equipment that you want to report on, control, schedule, or otherwise treat as logical entities within an Area.

  • In energy management applications: ideally each work center contains one or more (energy consumption) sensors.

  • In Enelyzer: only active in the Business Activity module, represended by a Work center.

• Work Unit

  • A smaller logical grouping of equipment for reporting, scheduling, or controlling execution.

  • In Enelyzer: represented as a Machine Group.

  • A Machine Group can contain other Machine Groups or Machines. Examples:

    • A Cooling installation is a Machine Group consisting of different components (compressor, heat exchangers, evaporator).

    • A Production line can also be a Machine Group, which itself contains other machine groups such as cooling installations in the line.

Notes: Equipment modules and control modules are not part of the base S95 standard. They are added as extensions of the model to unify the model with the S88 standard ISA-88 (S88) standard.
