Each OPC UA server publishes to the OPC UA clients its OPC UA functionalities via nodes
in its address area. You can find the read points or "RfidReaderDevices" under the node
"Objects > DeviceSet" in the address area of the OPC UA server of the communication
modules.
Figure 10-2 Node "Objects > DeviceSet"
You will find the methods/functions listed below under the following path in the address area
of a read point "Objects > DeviceSet > Readpoint_x1".
RFID-specific methods / functions
The integrated OPC UA servers of the communication modules support the following RFID-
specific methods/functions according to the "OPC Unified Architecture for AutoID" for each
read point:
