IEC 62453-302:2023

Overview - IEC 62453-302:2023 (FDT interface specification, CPF 2 / CIP)

IEC 62453-302:2023 is Part 302 of the Field Device Tool (FDT) interface specification series that defines how CIP™ / Communication Profile Family 2 (CPF 2) technologies are integrated into the FDT framework (IEC 62453‑2). The standard provides guidance for integrating CIP-based networks - including EtherNet/IP™, DeviceNet™, ControlNet™ and CompoNet™ - into FDT-based engineering tools and Device Type Managers (DTMs). It specifies communication and auxiliary services required for seamless device access and management, but it does not contain or change the core FDT specification.

Key technical topics and requirements

• Scope and intent: integration of CIP technology into FDT interfaces; mapping CIP profiles to FDT services.
• Protocol coverage: CPF 2 profiles based on IEC 61158 and IEC 62026 standards (EtherNet/IP, DeviceNet, ControlNet, CompoNet).
• Structured clauses addressing:
  • Bus category and physical layer identifiers
  • Access to instance and device data
  • Protocol-specific behavior and usage of general data types
  • Protocol-specific common and communication data types
  • Network management data types (node addressing, scanner/master parameters)
  • Channel parameter data types and device identification (topology scan, device-type mapping)
  • Implementation hints (informative annex)
• Interoperability focus: standard data types, mapping tables and behavioral rules to make DTMs interoperable with FDT Frames and engineering tools.
• Normative references: IEC 61158, IEC 61784, IEC 62026 family and IEC 62453‑2 are core referenced documents.
• Editorial/technical changes: third edition (2023) updates include improved support for EtherNet/IP.

Note: CIP, DeviceNet, CompoNet, ControlNet and EtherNet/IP are trade names of third-party organizations; the standard references these names for clarity but does not require use of those trademarks for compliance.

Practical applications

• Integrating CIP-based fieldbus devices into FDT-enabled engineering environments.
• Enabling vendor-supplied DTMs to operate consistently across different control-system tools.
• Standardizing device discovery, topology scanning, channel configuration, and network management for CIP networks in process and discrete automation.
• Supporting system integrators and automation OEMs in heterogeneous networks that combine Ethernet and legacy fieldbuses.

Who should use this standard

• DTM and FDT Frame developers
• Field device manufacturers and firmware engineers
• System integrators and automation suppliers
• Control and instrumentation engineers responsible for network engineering and device configuration
