I haven’t got clear answer for how Ignition should provide tag data for external softwares. OPC UA is just a driver, not provider for ignition tags, I guess, as written in topic Adding tags to "Ignition OPC-UA Server" thru designer
Or is there some new features for UA ignition tag publishing now?
3rd party modules, as Cirrus Link MQTT modules could be answer, but requires extra costs.
Of course http service or python tcp-listener could be used to listen connections and deliver tag data, but this requires some work to get it work efficiently.
But isn’t there standard way to read/write tags. We are trying to fit Ignition for our purposes, and normally tags can be published minimum via OPC DA/UA at least, without any extra cost.
How f.ex. Ignition graphic client for example reads/writes tags?
Thank you all in advance for support and answers : )
