Hello

In HMI project you can only work with HMI Tags. You can use internal HMI Tags that are only inside the HMI or you can use externeal Tags.

for each Datapoint you want to access to in a PLC or an OPC Server you have to create a external HMi Tag.

If you have an internal connection to the PLC (same project or Proxy device) you can browse in the DBs and the HMI tags are created automatically.
