Is there a protocol change in v21+ that is not supported by Ignition included drivers?

Yes, that’s exactly right.

Care to elaborate on the details of the protocol change? I do a great deal of low-level work with Ethernet/IP and I hadn’t noticed this.
(I did run into a protocol issue with recent A-B processors, but it affected all firmware versions on the newer processors.)
