OPC UA 1.02, Client

see also protocol(s)

OPC UA 1.02, Client is used to connect one or more OPC UA servers. The implementation is based on the OPC UA specification version 1.02.

The functional range of OPC UA Client / Server is defined by predefined profiles or facets (see part 7 of the OPC UA specification). The requirements in fully automated environments of communication gateways do not correspond to all predefined conformity points of a profile. Accordingly, the functional range of the OPC UA Client protocol stack is not described by a predefined profile, but consists of different, individual functional units (see tables below). All listed profiles, facets and function blocks relate to the document "OPC Unified Architecture Specification Part 7: Profiles Release 1.02 April 7, 2013", which provides the detailed definition of the function.

The protocol stack OPC UA 1.02, Client was tested with the following UA servers:

Definition of "Hot (2)" according to chapter 6.4.2.3, Non-transparent redundancy, "OPC Unified Architecture, Part 4, Release 1.02"

The client receives the same information from more than one server by sampling and publishing on more than one server. This mode ensures that there is no interruption in the data stream and no data loss. The client should ensure that it detects duplicate data and it must process two data streams.
