Although ISA-95 is an interface standard, the models described in part 1 and 2 of the standard are a good basis for a standardized manufacturing data model. 

Part 3 and 4 of the standard provide a more fine grained modeling, but these models are still based on the basic models that are provided:

  • Resources Models:
    • Personnel Model
    • Material Model
    • Role-based Equipment Model
    • Physical Asset Model
    • Process Segment Model
  • Information Models:
    • Operations Definition Model (How to do something ?)
    • Operations Capability model (What resources are available ?)
    • Operations Schedule Model (What do we like to do ?)
    • Operations Performance Model (What did we do ?)

Easy95 is based on normalizing your data towards the above models. Normalization is a methodology studied by the University of Antwerp to allow you to build growing systems without creating more complexity.

The resource models are mainly used to normalize data coming from the shop floor, because these models describe the base components that make up your plant: people, machines and materials.

The information models are mainly used to normalize data coming from your ERP layer, because here the context needs to be defined between the different resources, so the plant can 'actually' do something.

By building the user interfaces and functional modules towards your models, an abstraction layer is generated which makes the applications independent of the connected system. This way you can build Plant Apps like we are used to an smart phones.

Easy95 provides  a web based platform to implement a so called Operational Information Store (OIS) based on ISA-95.

This OIS can be implemented in any existing landscape and provides a services oriented environment.
