Read write tag values using Ignition's OPC-UA

From an Android APP.
Can this be done?

What do I need to do to accomplish this?

Easiest way would be to find yourself an OPC-UA client SDK that works on Android.

Do you mean I can’t access the OPC-UA from the Ignition Gateway ?
I think it would be faster than trying to handle communications and polling on a andriod device.
Does the gateway support JSON or something similar?

The values aren’t readily available by any other means than OPC-UA.

You could probably use the web-dev module or a custom module using the SDK to serve up SQLTag values in a format of your choosing over a web-based API.

Colby mentions this in the following thread. I have considered using an Android OPC-UA but I didn’t know it would be necessary. … ion#p37962

The best option looks like developing the communications from the Prosys SDK.
I thought you might have exposed some of the functionality of OPC-UA in the designer SDK.
I’m surprised there isn’t an open source solution for this.

Did you come across this one by chance?

I saw it Jordan.
I want to be able to communicate with Ignition through either through a TCP/IP socket
or JSON. I haven’t been able to find any documentation yet for how to do this, but I’m assuming it should be fairly straightforward.
