WebIQ ctrlX App connecting to an external OPC-UA server

[YUL725]

Hello,

I am using WebIQ app in the ctrlX core, can I built project that connect to an external OPC-UA server ? For Instance to a MLC OPC-UA server ?

Thank you

WebIQ supports any OPC-UA server - simply add your connection in the IO Manager and there you go:

Hello,

I am using WebIQ designer on PC, I configured to connection with IO Manager and added my variables, can test the App on from  PC, works well. Then After I publish the App on the Core , Start the app and  Log onto the WebIQ App on the core , the Page is loading but variables are not updating. It seems that the App does not connect to the MLC OPC-UA Server.  any Idea how to debug this ?

Thanks!

What do you see in IO Manager for the OPC-UA datasource? Does it show "connecting" or "connected"?
Which IP address did you use to connect to your OPC-UA server? Can it be reached from the ctrlX CORE via network?

For example when running your MLC OPC-UA server on your local system using 127.0.0.1 you'd of course have to change the IP address to the relevant external IP address of your system to be able to connect to it from ctrlX CORE.

I had to re-install WebIQ Designer to make it work. I am using 192.168.1.x  address range for all devices
