Event subscriptions are not possible right now.

I’m not sure how to “model” events in Ignition. They don’t fit as tags, so it’s unclear to me where you would define the events filters and where you’d react to or handle events.

Hey Kevin is this something that Ignition might be thinking about supporting at some point. We just encountered our first OPC Server that is using OPC Events and we have no way to subscribe to them. I've not seen an OPC Server implementation like this before either.

We're planning Event support for Ignition 8.3.
