In the process automation industry, Integration Technologies principally refer to software standards developed to assist in assuring multi-vendor interoperability between field instrumentation and host systems. As technology advances the integration challenge increases and standard must evolve or new standards created to meet the challenge.
FieldComm Group plays a key role in the process automation industry for integration technologies as owner or co-owner of several major specifications:
- FDI Technology (Field Device Integration)
- PA-DIM (Process Automation - Device Information Model) [OPC-UA based]
- EDDL (Electronic Device Description Language)
FieldComm Group, FDT Group, OPC Foundation, and PROFIBUS & PROFINET International are the co-owners of the FDI specification. FieldComm Group develops and maintains the FDI Specifications in its working group structure, establishing and controlling new technology developments and enhancements that support the needs of the process automation industry. FDI Technology is a globally recognized standard and is published by the IEC as IEC 62769.
FieldComm Group is the developer, co-owner and standards organization for the PA-DIM Specification. Based on OPC UA specifications and co-owned with the OPC Foundation, PA-DIM describes an information model for process automation instrumentation that can be integrated with IT and OT systems that support OPC UA technology.
DeviceInfo refers to a FieldComm Group member standard that standard that describes key information about HART devices in commonly used JSON and XML notation. DeviceInfo files are created automatically by FieldComm Group tools. The files are typically used in lightweight edge gateways as part of a large IIoT system.
The Electronic Device Description Language (EDDL) is a complete purpose built language and is is still the predominant technology used to create driver files for field instrumentation. EDDL includes device description, user interface, and functions/methods for configuring, modifying, and maintaining field instrumentation.
