Creating virtual devices in the ACCON OPC UA Server
22. January 2024 – Video

How to create a virtual device
To use virtual devices, you must configure them in advance in the Address Space Configurator of the ACCON OPC UA Server. Carry out the following steps there:
- Create or load a project: Create a new project or open an existing project in the ACCON OPC UA Server.
- Add a virtual device: Create a new device and set the type to "Virtual device".
Alternatively, operate an existing device virtually: To do this, open the device and click on Show advanced options. In the Virtual Device Mode section, simply activate the option Use this device as a "virtual device". - Add virtual symbols/variables: You can now add your virtual symbols via Configure address space. There are then three different options:
- Create manually via Add variable: Here you can define the variable name, data type and initial value directly in the user interface.
- Create via Virtual Symbols XML file: Load a corresponding Virtual Symbols XML file by selecting it on the right-hand side and then clicking on Load. You can now add individual symbols or all symbols at once to the address space. A separate video on the creation and structure of a Virtual Symbols XML file will soon be available on our YouTube channel.
- Importing UA NodeSets: More information on this soon in a separate tutorial.
- Transfer the project to the server: To do this, simply click on Transfer project to server on the start page of the Address Space Configurator and confirm.
- Using virtual symbols in the UA Client: You can now open your UA Client application and see the virtual symbols there. These can be used in the same way as other variables.
