Overview
IEC TR 62453-51-150:2017 is a Technical Report published by the International Electrotechnical Commission (IEC). The standard belongs to the Field Device Tool (FDT) interface specification series and specifically addresses the communication implementation for the common object model for IEC 61784 Communication Profile Family 15 (CPF 15), which includes Modbus TCP® and Modbus Serial Line® protocols. Its main purpose is to facilitate the integration of these protocols into FDT systems that use a COM-based implementation, promoting seamless interoperability of field devices and engineering tools across various vendors.
This report is intended for use alongside IEC TR 62453-41 and does not itself contain or modify the core FDT specification. Instead, it details the mapping of Modbus parameters to FDT data types and provides guidance for their implementation within industrial automation environments that require standardized device integration.
Key Topics
- Protocol Integration: Information and guidelines for mapping parameters of Modbus TCP® and Modbus Serial Line® into FDT data types, ensuring compatibility and proper communication within FDT systems.
- Common Object Model: Describes how to implement communication services based on the FDT common object model, supporting standardized data handling and device management.
- Data Types and Structures: Specifies the use of various data schemas for Modbus within FDT, including address, communication, and network management data types.
- Method Access: Outlines the function calls and methods (such as IDtmParameter, IDtmSingleDeviceDataAccess) involved in accessing device data and controlling devices over CPF 15 protocols.
- Compliance and References: References additional standards (e.g., IEC 61158-5-15 and the MODBUS Application Protocol Specification) for restrictions and definitions not fully covered in this document.
Applications
Implementing IEC TR 62453-51-150:2017 brings practical value to several domains within industrial automation and process control:
- Engineering Tool Integration: Facilitates integration of a wide range of Modbus-capable field devices into system-wide engineering and planning tools, reducing vendor lock-in and simplifying device management.
- Interoperability: Supports mixed-vendor environments where devices from different manufacturers must coexist and communicate seamlessly within a unified FDT architecture.
- Device Type Manager (DTM) Development: Offers device vendors clear specifications for developing DTMs that conform to Modbus networking standards, ensuring reliable connections to FDT-based host applications.
- System Maintenance and Diagnostics: Allows access to standardized data types and protocol-specific services, enhancing the consistency of maintenance, diagnostics, and device parameterization tasks across fieldbus networks.
