Embodiment

[0057] Take Modbus device A connected to OPCUA based on TCP as an example:

[0058] 1) Map device A to the OPCUA address space. Device A is mapped to the Object node Device A of OPCUA, and the access mode TCP is set as the FolderType node type. The registers of the device are grouped according to the Modbus register type, and the node type of each group is FolderType. The type node DeviceType inherited from ObjectTypes is designed, and the device IP , port, device number (set automatically by the system) and other attributes are set as Property type nodes, and the Device A node is connected through the HasType Definition type reference, and the node type RegisterValueType inherited from BaseDataVariableTypes is designed, and the register properties, register type and register address are set as The Property type node is connected to RegisterValueType through the HasProperty reference type, and the register node references RegisterValueType through the HasTypeDefination type. ...

Abstract

The invention relates to an OPCUA and DDS protocol signal conversion device, a communication system and communication method. The OPCUA and DDS protocol signal conversion device comprises a protocol conversion module for converting an OPCUA protocol signal sent by an OPCUA server into a DDS protocol signal to be sent to a client, and converting a DDS protocol signal sent by the client into an OPCUA protocol signal to be sent to the server. The communication system and communication method based on the OPCUA and DDS protocol signal conversion devices combine an OPCUA module and a DDS module, not only realize the real-time performance and the low-delay performance of the DDS, but also meet the requirements of dynamic networking and data multiple distribution on demand of a complex system in a distributed network environment.

Description

technical field [0001] The invention relates to the communication field, in particular to an OPCUA and DDS protocol signal conversion device, a communication system and a communication method. Background technique [0002] OPC Unified Architecture (OPC Unified Architecture) is a standard that does not depend on any platform. With the help of this standard, various systems and devices can communicate in the client / server mode in different networks. Since the Foundation released the OPCUA specification in 2006, the specification has been continuously improved, and many domestic and foreign automation equipment providers and software companies have released products that support the specification. [0003] OPCUA is independent of the manufacturer, applications can use it to communicate, developers can use different programming languages ​​to develop it, and different operating systems can support it. OPCUA makes up for the deficiencies of the existing OPC, adding important fea...
