Dual-port-random access memory (RAM)-based embedded common Ethernet/Internet protocol (IP) communication interface device

Abstract

The invention discloses a dual-port-random access memory (RAM)-based embedded common Ethernet/Internet protocol (IP) communication interface device, which comprises a core board unit and a bottom plate unit, wherein the core board unit is used for receiving, transmitting, analyzing and processing the data information of an Ethernet/IP industrial network and external equipment, providing an indication logical for an indication circuit in the bottom plate unit, fixing system information and providing software support for the whole device; and the bottom plate unit is connected with the core board unit to form a whole by a core board interface circuit, and is used for communicating with the Ethernet/IP network to exchange Ethernet/IP data, communicating with the external equipment to exchange external data, providing a standard circuit interface for the external equipment, interconnecting the communication interface device and the external equipment, indicating the current working condition of the communication interface device and providing power supply and resetting functions for the communication interface device. The dual-port-RAM-based embedded common Ethernet/IP communication interface device has high universality, and can exchange Ethernet/IP data information with any external equipment when the external equipment meets the specifications of the interface circuit in the communication interface device.

Description

technical field [0001] The invention relates to the technical field of industrial network communication, in particular to an embedded universal Ethernet / IP communication interface device with wide versatility. Background technique [0002] In recent years, the industrial automation control system has been developing in the direction of intelligence, informationization and networking. Among all network technologies, Ethernet technology based on TCP / IP protocol has become a de facto standard network, extending standard TCP / IP Ethernet to the field of industrial real-time control, and is comparable to the common industrial protocol CIP (Common Industrial Protocol1). Combined, industrial Ethernet Ethernet / IP is formed. [0003] Since the development of Ethernet / IP is not long, and it has just started in China, the promotion of Ethernet / IP in my country is facing various problems, such as high development costs and a serious shortage of professional technicians, etc., which rest...
