Survey of a tentative project phase #4

After the successful completion of phase #3 of the industry funded and OSADL steered community project: "Building an Open Source OPC UA over TSN Ecosystem", there were plans to start phase #4 and further develop next generation real-time Ethernet. Everybody was invited to suggest features that should be included in phase #4. The outcome of this survey was considered when drafting the Letter of Intent of phase #4 referenced below.

Project phase #4 (completed)

Tasks and priorities

The project activities are broken down into work packages as described below. All following software components planned to be developed and support planned to be delivered will be governed under the conditions of the Letter of Intent:

  1. High priority
    • Load and store information data model at run time through configuration file (not statically compiled in firmware)
    • Implement “reverse connect feature” as described in "OPC 10000-7 - Part 7: Profiles", chapters 6.6.5 Reverse Connect Server Facet and 6.6.75 Reverse Connect Client Facet
    • Complement the ongoing project to update the OPC client/server release to version 1.05 without overlapping with the parts already commissioned
    • Implement support of PubSub state machine according to OPC10000-14, chapter 6.2.1
  2. Medium priority
    • Companion specification selection in the build system for fast integration
    • Automatic size-reduction of the information model by white-listing and dependency resolution
  3. Low priority
    • Further CPU and memory optimizations for resource constrained devices (identify, document and implement optimizations for memory and CPU footprint)
