Hi guys!

I've read some/all post touching this A&E subject in the forum, but if you don't mind (I know you don't 😉), I'd like to wrap up a few points which are confusing us:

1. We have a few SCADA systems (not Ignition) with configured Alarms & Events.
2. We'd like to send the data involving those alarms to Ignition, which we're using just as a data hub for storage and visualization, for consolidation and analysis. We'd like to avoid having to duplicate all the tags and alarms in Ignition.

Is this -theoretically- possible? As I understand:

1. On the SCADA side, I just need an OPC AE Server.
2. On the Ignition side, I need an OPC AE Client, which Igntion still doesn't have, I know but...can we use a third party (TP) OPC AE Client, and connect it -somehow- to Ignition's OPU UA Client. Something like:

TP SCADA -\> TP OPC AE Server -\> TP OPC AE Client -\> Ignition OPC UA Client -\> Igntion

I'm not sure an OPC AE client can output the information in a format that would be readable by an UA client or any other human-readable format that Ignition can ingest.

Thanks and regards.

PD: The usual disclaimer: not an integrator, just a curious challenger.

I doubt there's anything that changed since Kevin's answer last year:

> [@OPC-UA Alarms and Conditions](https://forum.inductiveautomation.com/t/opc-ua-alarms-and-conditions/25033/17):

> You might be able to find a 3rd party OPC UA server that subscribes to events and in turn exposes them as a set of regular variables or something. Not really sure how that would work in practice.

So, maybe.
