Overview
IEC 62769-100:2023 - Field Device Integration (FDI®) Part 100: Profiles – Generic Protocols - defines a standardized FDI profile for Generic Protocols to enable interoperable communication between hosts, gateways, communication servers and field devices. Published as Edition 2.0 (2023), this profile specifies all interfaces required so a host can add support for additional field protocols without changing its core implementation. The standard also identifies protocol specific definitions (PSD) that each protocol must supply (see Annex C) so FDI Device Packages, Communication Packages, Gateways and Communication Servers can operate together seamlessly in hosts that are not natively aware of those protocols.
Key topics and technical requirements
- Profile scope and catalog profile: Defines the catalog and ProtocolSupportFile concepts used to declare protocol compatibility for Device Packages and Communication Packages.
- Device-package association: Mappings for device type identification and device revision enabling consistent package association with devices.
- Information model mapping: Definitions such as ProtocolType, DeviceType mapping and FunctionalGroup identification to map protocol data into the FDI information model.
- Topology elements and discovery: Generic definitions for ConnectionPoint, Communication Device, Communication Service Provider and Network plus a topology scan result schema (Annex A).
- Methods and services: Standardized methods for FDI Communication Servers and Gateways (for example Connect, Disconnect, Transfer, SetAddress), and transfer service parameters (detailed in Annex B).
- Protocol Specific Definitions (PSD): Annex C lists required PSDs (header, ProtocolIdentifier, Address formats, Manufacturer, DeviceModel, Versioning items like ExtendedDeviceRevision) that each protocol implementation must define to ensure interoperability.
- Versioning and compatibility: Support for protocol version information and ExtendedDeviceRevision to manage evolving implementations.
Practical applications and who uses this standard
IEC 62769-100 is intended for:
- Device vendors creating FDI Device Packages for field instruments and controllers.
- Gateway and Communication Server developers implementing protocol interfaces and Communication Packages.
- Host system vendors and system integrators who need to support multiple fieldbus/protocols without redesigning host software.
- Automation engineers and system architects aiming for vendor-neutral device integration, simplified commissioning and consistent device management across protocols.
- Certification bodies and QA teams validating FDI interoperability and protocol conformance.
Benefits include reduced integration effort, predictable device-package binding, standardized topology discovery and a clear route to add new protocol support while preserving host stability.
