Abstract

The invention discloses a gateway for realizing Internet communication between an EtherCAT (Ethernet for Control Automation Technology) industrial Ethernet and a WorldFIP (Factory Instrumentation Protocol) field bus and a realization method thereof. The gateway comprises an EtherCAT bus protocol controller, an EtherCAT bus transceiver, a main control unit, a WorldFIP bus protocol controller and a WorldFIP bus transceiver, wherein the main control unit is connected with the EtherCAT bus protocol controller and the WorldFIP bus protocol controller respectively; the EtherCAT bus protocol controller is connected with the EtherCAT bus transceiver; and data exchange between the EtherCAT bus protocol controller and the WorldFIP bus protocol controller is realized by using the main control unit. According to the invention, the Internet communication between the EtherCAT industrial Ethernet and the WorldFIP field bus is realized, and the EtherCAT industrial Ethernet and the WorldFIP field bus can be used together in the same industrial control system.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a gateway for realizing interconnection communication between EtherCAT industrial Ethernet and WorldFIP field bus and its realization method Background technique [0002] As industrial control systems in various industries have increasingly higher requirements for automation and the amount of data in the system increases, the advantages of industrial Ethernet are becoming more and more obvious. For example, in the field of locomotive control network, the requirements for locomotive automation and comfort are getting higher and higher. The amount of on-board data such as train operation control, passenger information system, and multimedia is also increasing rapidly. Traditional field buses such as CAN, DeviceNet, PROFIBUS, and WorldFIP are gradually emerging. The defects of low transmission rate, limited application support and poor compatibility have become the bottleneck restr...
