OPC UA basic methods/basic functions
The integrated OPC UA servers of the communication modules support the following OPC
UA basic methods/basic functions:
● OPC UA server basic functions according to the "Micro Embedded Device Server Profile"
of the OPC Foundation.
As an extension of the "Micro Embedded Device Server Profile":
– "Standard DataChange Subscription Server Facet"
– "Standard Event Subscription Server Facet"
– "SecurityPolicy - Basic128Rsa15"
– "SecurityPolicy - Basic256"
– "SecurityPolicy - Basic 256Sha256"
– Maximum 5 OPC UA client connections
● "Full AutoID Server Facet" according to the specification "OPC Unified Architecture for
AutoID" (Release 1.00). Each reader interface stands for a read point and thus for an
independent "AutoIdDevice" or "RfidReaderDevice". This means that each
communication module supports as many read points as the number of devices that can
be connected.
● On an communication module, an OPC UA client can be connected as a second
application to a PROFIBUS main application.
For an OPC UA client to also be able to connect, the "Parallel" parameter must be
selected in the WBM in the "Communication > OPC UA" menu. This case is intended
purely for diagnostics purposes, so write access is no longer possible here for OPC UA
clients.
The assignment of the OPC UA read points to the connected devices is derived from the
read point names. You can find these in the read point attributes.

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.
