Embodiment Construction

[0016] refer to figure 1 According to the actual on-site use and integration of the gateway completed by the present invention, the cooperation of the PC configuration software and the OPCUA gateway embedded software is required, the PC configuration software completes the generation and download of the mapping relationship file, and the embedded software completes the reception and interpretation of the mapping relationship file And execute, the corresponding equipment can be connected through the Modbus and Profibus interfaces on the OPCUA gateway, and can be integrated with OPCUA-equipped SCADA and other software / systems through OPCUA as a unified interface.

[0017] refer to figure 2 , for Profibus devices to OPCUA address space, mainly consider device mapping and point item mapping, for Profibus device attribute parameters are slave station address, communication rate, corresponding to OPCUA is IP address, subnet mask and default gateway; for Profibus data points The it...

Abstract

The invention discloses a method for automatically mapping multiple industrial protocols to an OPC UA address space. Functionally, the method comprises a mapping relation generator, a mapping relation file downloader, a mapping relation file receiver, a mapping relation interpreter and a mapping relation executer; the mapping relation generator mainly realizes the function of automatically mapping Profibus (Process Field Bus) and Modbus industrial protocols to the OPC UA address space and outputs mapping relation files; the mapping relation file downloader realizes the function of downloading the mapping relation files to an embedded OPC UA gateway; the mapping relation file receiver matches with the mapping relation file downloader and realizes the function of receiving the mapping relation files; the mapping relation interpreter interprets the automatic mapping relation used by the generator so as to construct memory mapping relation; the mapping relation executer realizes functions of converting, reading, writing and subscribing the data between the Profibus and Modbus devices and the OPC UA uniform interface. According to the invention, the functions can be realized on any platform; the bottom layer site data and the upper layer monitoring and management system in the industrial automatic field are integrated.

Description

technical field [0001] The invention relates to the field of industrial automation, and is applied to data standardization and integration in the field of industrial automation, in particular to the PROFIBUS-DP / PA bus protocol, MODBUS bus protocol and OPCUA protocol in the field of industrial control. Background technique [0002] PROFIBUS is the abbreviation of Process Field Bus (Process Field Bus), which officially became the international standard of field bus in 1989, and is also the national standard of China. It consists of three compatible parts such as PROFIBUS-DP and PROFIBUS-PA. Among them, PROFIBUS-DP is applied to the field level, and is used for communication between the device-level control system and distributed I / O to ensure fast and effective data transmission; PROFIBUS-PA is suitable for process automation, which can connect sensors and actuators to On a shared bus, it can be applied in the field of intrinsic safety. Profibus field bus occupies a dominant...
