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.
