Maximum number of usable OPC UA client interfaces
If you create OPC UA client interfaces using the connection parameter assignment, the
number of client interfaces is limited to 40.
Create the OPC UA client interfaces by double-clicking the "Add new client interface" symbol
in the project tree of the "OPC UA communication" area.
The maximum number of OPC UA client interfaces is independent of whether you also use
the CPU as OPC UA server.

Example configuration for OPC UA

The following sections describe how you can use the client interfaces editor and the
connection parameter assignment.
The description is based on a specific example: Two S7-1500 CPUs operate in the system:
One CPU serves as the OPC UA client and the other as the OPC UA server.
You can, of course, also use controllers, sensors and IT systems of other manufacturers as
OPC UA clients or servers. In particular, the data exchange between different systems
(interoperability) is a major advantage of OPC UA.
