Topics: Major improvements:
  • New Specifications for Nested Communications were added.
  • The FDI Technology Version variable (FDI_TECHNOLOGY_VERSION) is incremented when a new technology or a change in existing behavior that conflicts with existing behavior is introduced. This variable was added for FDI 1.4.0. FDI Technology version in FDI Specification was inadvertently set to 4 bytes in version 1.4, this is corrected to 2 bytes in version 1.4.1. This is now consistent with the EDDL specification.
  • EDDL predefined variable FDI_TECHNOLOGY_VERSION remains at 0x0104 for this version of the specification.
  • Updates including bug fixes and extended sequence diagram for blob storage.

New Feature: Nested Communication
Nested Communication and supporting features added to enable data exchange between the physical device and the device representation managed by the FDI Server. FDI network infrastructure is supported by switches, remote IO, and other infrastructure devices. The architecture supports device variants, Remote I/O, and Gateways. All configurable modules use the same vendor-specific bus protocol on the client side, while the head station supports the protocol on the server side.
