Notes:
- Certain device drivers do not have a list of Register Names in the DeviceHub Add/Edit Tag form. These are Free Tag PLCs. For Free Tag requirements, see Device Connectivity Issues.
- For the Register Name, in the DeviceHub Add/Edit Tag form, map the OPC server tags to the client using this format: ns=1;s=tagname.
- Example: ns=2;s=Demo.Static.Scalar.Boolean
- Server Name currently is not used, however, an entry must be made in this field.
- The Browse icon displayed on the device tile means that this PLC uses Browse Tags. See Add Tags for more information.
When you Add Tags to the connected device, use the following tag/register mapping table.
