Modeling and Design#

Use this section before creating connection settings or machine nodes.

  1. MES Modeling defines the Resource, hierarchy, contexts, and state model needed by the features.
  2. Architecture and Responsibilities assigns responsibility across the machine, OPC UA Server, Connect IoT, MES, and operator, and connects the architecture to the end-to-end production process.
  3. OPC UA Address Space defines the Resource base node and functional node tree.
  4. Integration Patterns applies the same standard to automated workcells, hybrid stations, and shared OPC UA server deployments.

The project should approve the MES model and the machine interface contract together. Changes to Resource hierarchy, parameter names, or state models can change NodeIds and runtime resolution.
