3. Add variables…..
Now you are ready to add “Tag Groups” – Right-click the level 2 of the configuration and select “Insert Slave/Data block”, and enter a name for the tag group. The “Tag Group” is a way to organize your data points in the OPC UA Server. Once done adding the needed tag groups, add the variables to the tag group(s). Right-click the “Tag group” and select “Insert variable” and configure the following:
- Select the application variable to map
- Write the OPC Tag name – the name visible to the OPC UA Clients
- Select whether the OPC UA Client has “Read Only” Or “Read/Write”-access to the variable.
