ANSI/ISA-62453-315 (103.00.09):2018

ANSI/ISA-62453-315 (103.00.09)-2018, Field Device Tool (FDT) Interface Specification – Part 315: Communication Profile Integration – IEC 61784 CPF 15, defines the field device tool (FDT) interface specification for integrating Modbus communication profiles, specifically Modbus TCP and Modbus Serial Line, into FDT-based industrial automation systems. This standard provides detailed mappings of Modbus protocol parameters to FDT data types within a client/server architecture, enabling device-specific software components called Device Type Managers (DTMs) to interact with field devices from multiple manufacturers in various control environments. It covers essential aspects such as protocol identifiers, physical-layer specifications, address information, communication and transaction services (including reading and writing coils and registers, diagnostics and device identification), broadcast and unconfirmed request handling, channel parameter definitions, network management and device type identification. By adopting this standard, engineering teams can develop and integrate tools that facilitate consistent communication and control across diverse Modbus-enabled devices, supporting tasks like process monitoring, device configuration and troubleshooting while promoting interoperability and structured data exchange in complex industrial networks.
