short identifier used to uniquely identify an X.509v3 Certificate.
Note 1 to entry: This is the SHA1 hash of DER encoded form of the Certificate.
way to serialize OPC UA Messages and data structures.
a value that is used when no other value is known or available.
suite of tools and/or programming languages used to create software.
specification on how to implement an OPC UA feature with a specific technology.
Note 1 to entry: For example, the OPC UA Binary Encoding is a Mapping that specifies how to serialize OPC UA data structures as sequences of bytes.
a sequence of zero or more octets without any length prefix.
Note 1 to entry: an OctetString is not defined as a DataType and only used in this document when a ByteString is not appropriate.
Protocol which ensures the integrity and privacy of UA Messages that are exchanged between OPC UA applications
combination of DataEncodings, SecurityProtocol and TransportProtocol Mappings
Note 1 to entry: OPC UA applications implement one or more StackProfiles and can only communicate with OPC UA applications that support a StackProfile that they support.
full-duplex communication link established between OPC UA applications.
Note 1 to entry: A TCP/IP socket is an example of a TransportConnection.
