Update on High Speed ISOBUS
Following on from the very successful High Speed ISOBUS presentation given at the Landtechnik conference in November last year, this edition of the newsletter seemed to be the right time to give a progress update as well as provide a bit more background about Project Team 10. (Just in case you were not at the conference, the information presented can be found on the AEF website in the Activities Section).
Project Team 10 was formed in early 2014 and is currently led by Dave Smart from John Deere and the deputy is Volker Brill from Claas. The number of activities that PT10 had to work on necessitated the formation of five subgroups (SG). SG 1 is investigating the physical layer, SG 3 is investigating the architecture and SG 4 is working on the protocols. Even with the current situation these SGs have been having virtual meetings, some meeting every two weeks, to keep the different activities moving.
SG 2 was investigating the wireless possibilities of a high speed isobus and concluded that it was not the right direction so has since been closed. Meanwhile the simulation group SG 5 has also been closed as they had completed their investigation to determine the maximum data loads for all the different HSI use cases. This simulation work helped the architecture group (SG3), decide on ethernet (1000Base-T1 PHY) as the most suitable architecture.
The protocol group (SG4) are actively investigating whether OPC-UA or SOME/IP would be the most suitable, the first being more “process control” oriented whilst the second is more automotive oriented, a decision on this is expected towards the middle of this year. However, one of the biggest steps forward so far has come from SG1 (Physical layer) with the decision to use the connector design from Rosenberger. This decision was reached after exhaustive analysis of the technical and business documents that each potential connector supplier submitted. Prototypes should be available to order in the last quarter of 2020 and the first production parts are expected in the last quarter of 2021 (just in time for Agritechnica).
So, the High Speed ISOBUS team is actively moving forward and, the work of PT10 will be released in a number of AEF guidelines starting from 2021.
