Install the PLC, OPC-UA Server and WebIQ Runtime apps on ctrlX CORE (minimum requirement).
We will use OPC UA communication to exchange variables between WebIQ and PLC app on ctrlX CORE. First of all, create a Symbol Configuration on the PLC app with all the variables you want to exchange with the HMI. Login and Run the application.
Open WebIQ Designer and create a new project. To configure the OPC-UA communication, open the IO Manager. Select “Create Entry” to create an IO Handler and add the hightlighted fields.
Note: on crlX CORE verify that the certificates are trusted (otherwise an error concerning the IO Handler creation is displayed).
To create the variables in exchange with the PLC, go to Process Data Manager. Click on the Variables section and use the Browse option.
For more information on how to use the Browse functionality, read the How-To guide WebIQ - Browsing of Variables, Arrays & Structures in OPC UA
To display the variable on screen, go to Layout Manager. Select the Widget you want to display the variable in and link the Item to the Widget.
Save the project. Click on Publish to transfer the project on the runtime.
Go to Home. From the Project List, Start the project you want to display on the runtime.
Go to yourIPaddress:10123/projectname/ using your favourite browser. Insert username and password configured for the project.
You now have your working HMI.
