Updated FDI Specifications Released

New Specifications for Nested Communications and More

This release introduces a standardized approach for implementing nested communications in FDI, enabling Host Applications (FDI Servers) to access end devices through intermediate networking infrastructure.

For developers, the new specifications define how switches, gateways, remote I/O and other communication devices are represented and integrated within FDI, providing a common mechanism for reaching end devices across mixed-topology architectures.

FDI Release Highlights

New and updated specifications as part of this release:

• New: FCG_TS62769-6-300 - FDI Technology Mapping for Gateway Plugins

• New: FCG_TS62769-9 - FDI Gateway Devices

• Updated: FCG_TS62769-4 - FDI Packages as well as other specification parts have also been updated to support nested communications and modular device architectures. 

Additional technical updates:

• Correction of the FDI_TECHNOLOGY_VERSION variable from 4 bytes to 2 bytes to align with the EDDL specification

• FDI_TECHNOLOGY_VERSION remains 0x0104

• An extended sequence diagram for blob storage

• Additional specification clarifications, corrections, bug fixes, as well as existing documents 

Review and Plan for Adoption

Developers should review the the updateed FDI specifications and evaluate how the new nested communication capabilities can be adopted in current and future FDI implementations.
