Overview
IEC 62769-7:2015, titled Field Device Integration (FDI) - Part 7: FDI Communication Devices, is an international standard from the IEC that specifies the elements responsible for implementing communication capabilities within FDI architectural frameworks. As part of the wider IEC 62769 series, this document provides essential guidance for the integration and management of Communication Devices-components that enable connectivity and interoperability among field devices, networks, and enterprise systems in process automation and industrial environments.
Use of FDI Communication Devices, as outlined in IEC 62769-7, is fundamental for ensuring uniform data exchange, scalable network management, and system-wide interoperability in automated processes.
Key Topics
- FDI Communication Devices: Defines both physical and logical entities that implement communication functions within a network using specific protocols.
- FDI Communication Server: Outlines specifications for dedicated OPC UA Servers that provide access to field device networks, enabling centralized device communication and configuration.
- FDI Communication Gateway: Describes devices that bridge different physical networks or protocols, supporting heterogeneous network topologies by enabling communication across various standards.
- Information Model Representation: Specifies how communication devices and their relationships are represented in the FDI Server-hosted Information Model, supporting accurate network topology mapping.
- FDI Communication Packages: Details required content and handling for communication packages, including business logic and connection management.
- Communication Relations: Establishes rules for relationships between physical devices, logical representations, and service objects, ensuring consistent data flow across the automation hierarchy.
- Integration with OPC UA: Leverages OPC Unified Architecture for standardizing device communication and access to device data.
Applications
IEC 62769-7:2015 is vital for a variety of industrial automation and process control applications, particularly where seamless device integration and communication flexibility are required, such as:
- Process Industries (Oil & Gas, Chemical, Power Generation): Ensuring effective field device integration in distributed control systems, enabling monitoring, diagnostics, and remote management.
- Industrial Automation Vendors: Supporting the development of FDI-based hardware, software, servers, and gateways that must comply with global interoperability standards.
- System Integrators: Facilitating integration projects that require bridging legacy systems with modern automation networks, leveraging FDI Communication Gateways for multi-vendor environments.
- Plant Operations and Maintenance: Improving the management of complex device networks by utilizing unified information models and simplified configuration through FDI Communication Servers.
