Last time, I showed how to install the Ctlx Works and Ctlx PLC Apps and launched a simple PLC application. This time, I would like to introduce the Real Data Layer function, which is very convenient for exchanging data between Ctrlx PLCs. That functionality is also available in ctrlX CORE and ctrlX COREvirtual.
The example below is actually a Data Layer concept. To put it simply, different applications such as PLC-Runtime, NodeRed, C/C++ can exchange data via the layer. It is an image similar to TwinCAT’s ADS and Siemens’ S7 Communication.

Open your project from ctrlx PLC Engineering, and create the Symbol Configuration by Application>Add Object>Symbol Configuration.
Check the Include Comments XML and Support OPC UA features options and Add it.
Symbol Configuration is created.
Program
Since we have to use the variables we want to create Symbols inside your project, we will temporarily add 1 program.

Download
Before downloading the program, first change the IP address of VirtualControl-xxxx’s Network Adapter from the Control Panel.

Login again and confirm with Yes.
Program is downloaded.
Run your Runtime Application.
Result
From Web Server, click Settings > Data Layer.
If you expand plc>app>Application>sym, you can see the GVL defined earlier and the variables in it, and you can also check the current value.
