Industrial on-site equipment data acquirer of multiple industrial buses

Abstract

The invention relates to an industrial on-site equipment data acquirer of multiple industrial buses, specifically relates to a protocol conversion and communication device between different industrial buses. The industrial on-site equipment data acquirer of multiple industrial buses is characterized by comprising a central microprocessor, a power supply module, a signal acquisition module, a communication interface and a clock module, wherein the central microprocessor is respectively connected with the power supply module, the signal acquisition module, the communication interface and the clock module. The industrial on-site equipment data acquirer of multiple industrial buses is not only applicable to large systems, but also applicable to small systems which are simple in network framework and low in required cost, and is wider in application range.

Description

technical field

[0001] The invention relates to an industrial automation equipment. Specifically, it is a protocol conversion and communication device between different industrial buses. Background technique

[0002] At present, with the rapid growth of the network access market, the process data acquisition of industrial field equipment in the existing market has high requirements on factors such as real-time performance, anti-interference performance and environment. China 200610025002.1 patent specification discloses a process data acquisition method for industrial field equipment, which configures acquisition terminals, OPCServer, telegrams and data points in MuhiLink for PLC equipment supporting the OPC protocol. For the data communicated through XCOM, configure communication terminal, message, channel and other information. Call the one provided by MuhiLink or XCOM. API read and write interface, write and read text. The read message is parsed according to the messa...
