Alarm and Events Feature in PubSub Application|OPC UA Standard|Forum|OPC Foundation

Hello,

I am an end programmer who aims to gather data from several PLCs and publish this data via OPC UA Publisher. Generally, I intend to publish data in a cyclic manner, and so far, it has been successful.

However, in some specific scenarios, I would like to publish data only under certain conditions. Upon reviewing the OPC UA specification document, it seems that ‘PublishedEventData’ is exactly what I need.

However, I came across this post on the Issues page:

It appears that it hasn’t been addressed since December 2, 2022. Is there any possible way to publish data in a non-cyclic manner now?

If this is currently under development, as a .NET developer, is there a way I can contribute to or assist you guys?
