OPC UA server interface configuration

A server interface combines nodes of an OPC UA address space of a CPU into a unit, so that a

specific view on this CPU is provided for OPC UA clients.

Each server interface defines one or more namespaces in the OPC UA server of the CPU.

STEP 7 (TIA Portal) differentiates between the following types of server interfaces:

• Companion specification

For this type of server interface, you use a Companion Specification created by a

workgroup, for example.

The workgroup is typically composed of members of the OPC Foundation and another

industry organization who have jointly specified an OPC UA information model for a

specific purpose (for example, for data exchange with RFID devices or with injection

molding machines).

This information model is realized in the form of OPC UA nodes in the address space of an

OPC UA server. OPC UA clients can access these OPC UA nodes.

You can also use the server interface type "Companion specification", for example, to

download company-internal information models, e.g. in SiOME.

If you implement a certain companion specification in your project, you apply the

specifications of this companion specification into your project as server interface.

For "Companion specification"-type server interfaces, you can import multiple namespaces

which the Companion specification uses.

Additional information on companion specifications is available here (Page 245).
