Introduction

This section provides specifications for OPC Unified Architecture application developers. This standard is given for the development of standard interfaces for analysis and design

The standard interface accelerates application development by multiple vendors and seamlessly integrates internal operations.

OPC Unified Architecture Part 4. Services

1 Scope

GB/T 33863 This part of the definition of OPC Unified Architecture (OPCUA) Services (Services). The service described is abstract

Collection of remote procedure calls (RPCs). The service is implemented by the OPCUA server and is called by the OPCUA client. OPCUA customer

All interactions between the terminal and the server are through these services. Since this section does not define a specific RPC implementation mechanism, so this

The partially defined service is abstract. IEC 62541-6 specifies one or more specific mappings for implementation. For example, IEC 62451-6

There is a mapping to the XMLWeb service. In this mapping, the services defined in this section act as Web services in a WSDL contract

Method appears.

Not all OPCUA servers need to implement all defined services. IEC 62541-7 defines the rules that are specified for AND

Specific rules compatible, which interface needs to be achieved.

This section is intended to guide the development of OPCUA client or server applications.
