Figure 9-8 "UA Sample Client" program of the OPC Foundation
A connection to a server end point is only established if the OPC UA client complies with the
security policies of that end point.
Through the information provided by the OPC UA server
OPC UA servers provide a wide range of information:
● The values of PLC tabs and DB components which clients may access.
● The data types of these PLC tags and DB components.
● Information on the OPC UA server itself and on the CPU.
This gives clients an overview and allows them to read out specific information. Previous
knowledge of the PLC program and the CPU data is not required. You do not need to ask
the developer of the PLC program when PLC tags are to be read. All necessary information
is stored on the server itself (for example, the data types of the PLC tags).
