CNC Systems Information Model
This specification was created by a joint working group of the OPC Foundation and VDW. It defines an OPC UA Information Model to interface and exchange data with Computerized Numerical Control (CNC) systems.
It allows to access data provided by a CNC system, namely parameters, state data, process and command data, alarm notifications and files. Access covers both read and write access. Thus, the following use cases may be covered:
- Setup: The CNC data interface provides data that can be used for setting up a production system controlled by a CNC. This refers first of all to production commissioning data (e.g. job description, tool data etc.) but implies to a certain extent as well CNC configuration data (e.g. axis parameters, cycle time etc.), as needed for engineering.
- Operation: The CNC data interface may be used for operating a production system controlled by a CNC and therefore serves as a connection point for user interfaces.
- Observation: The CNC data interface may be used for observing a production system controlled by a CNC and therefore serves as a connection point for monitoring and diagnosis applications and for user interfaces.
The specification is still in release candidate status (March 2015)
