Industrial Ethernet protocol converter

Abstract

The invention discloses an industrial Ethernet protocol converter and relates to a digital information transmission data switch network. The industrial Ethernet protocol converter comprises a hardware part and a software part, wherein the hardware part is composed of a microprogrammed control unit (MCU) module, a power supply module, a RS485 serial interface module, an Ethernet interface module, an external expansion memorizer, a communication state indicating module and a reset and crystal oscillator circuit. The software part comprises an Open transmission control protocol (TCP) protocol stack embedded in a singlechip and a hyper text transport protocol (HTTP) webpage protocol embedded in the singlechip. The hardware part takes the MCU as a central component, and achieves the connection with a Modbus network through the RS485 serial interface and the connection with the industrial Ethernet with the Ethernet interface module, and all the hardware parts cooperate mutually to enable the Modbus network to be communicated with the information of the industrial Ethernet. The industrial Ethernet protocol converter achieves high-speed and real-time communication of on-site equipment of the Modbus network, and overcomes the defects that installing space is large, cost is high and installation is inconvenient in the prior art.
