[quote=“PenCapBlue”]Do you guys keep an up to date product compatibility matrix?
I’m currently working on rolling back a PLC project from V21 to V19 due to Ignition incompatibility, and I did not see any caveats on this page: inductiveautomation.com/products … drivers/ab
Are there any workarounds at the moment?[/quote]
We don’t have a matrix anywhere because it wasn’t previously an issue. I’ll talk to the web guys about getting something up there.
Either way, in 7.6 drivers have clear descriptions in the gateway, and the *Logix drivers have been updated to state that they support firmware v20 and lower.
As for workarounds, just use another OPC-UA server like Kepware that has support for the v21 firmware.
