This document provides an Information Model enabling data interoperability between systems in the field, including Controller-to-Controller, Controller-to-Device, Device-to-Device and Controller/Device-to-Compute. It includes base Information Models for devices and controllers, ensuring smooth, high-speed information flow for critical factory and process systems. These systems can include safety systems. It is expected that the Information Models specified in this document will be extended to include other specific device or system types like motion control. For a complete overview, see OPC 10000-80.
This initial scope includes Controller-to-Controller using PubSub for data exchange. A future release will include Controller-to-Device and Device-to-Device. A future release will also include Client Server for data exchange.
