I've successfully tested both out-of-order/direct-to-historian and in-order/flush (replay) S&F modes (on both MQTT Engine tags and reference tags) using 4.0.19 Transmission/Engine modules.
I'm now curious if the latter (replay) method will flush/replay the cached data all the way through Ignition's OPC UA server - and if an OPC client will successfully log those historical values (if it's writing to a CSV or DB, for example).
It seems it should work in theory, but testing thusfar has failed to validate that.
Any thoughts on the matter @wes0johnson?
