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:

OPC UA methods
Scan
Synchronous execution of inventories
The detected transponders are directly returned.
ScanStart, ScanStop
Trigger the read points to start inventories.
The detected transponders are delivered by means of events (Rfid-
ScanEventType).
KillTag
Destroy transponders.
This function is only supported by UHF readers.
LockTag
Lock areas on the transponder.
This function is only supported by UHF readers.
SetTagPassword
Set transponder-specific passwords.
This function is only supported by UHF readers.
ReadTag
Read out transponder data.
WriteTag
Write transponder data.
