Problems solved by technology

[0005] At present, in order to communicate between devices, traditional I / O modules need to connect the external endpoints of the device with the endpoints of the controller one-to-one through wires. This hard-wired connection method requires a lot of energy for on-site assembly and debugging. And with the complexity of the system will increase a lot of hard wiring costs

Abstract

The invention discloses an Ethernet / IP protocol based remote I / O (Input / Output) module with short-circuit protection and self diagnosis function, which comprises a core plate unit and a base plate unit, wherein the core plate unit is used for providing a core microprocessor, an internal memory and a flash memory for a whole system platform so as to guarantee the normal operation of a real-time operation system and Ethernet / IP protocol program, and the base plate unit is used for performing data communication with Ethernet / IP industrial Ethernet and field data communication with an I / O short-circuit protection and self diagnosis unit, acquiring I / O interface state diagnosis data, cutting off the power to carry out short-circuit protection when the I / O interface circuit has short circuit and displaying the state of an I / O interface. The Ethernet / IP protocol based remote I / O(Input / Output) module has short-circuit protection and self diagnosis function, can cut off the power and provideself diagnosis information when an interface power supply has short circuit and can automatically resume work when the fault is shoteliminated.

Description

technical field [0001] The invention relates to the field of communication and embedded system application technology, in particular to an I / O module based on the Ethernet / IP industrial Ethernet protocol with short-circuit protection and self-diagnosis functions. Background technique [0002] In recent years, with the wide application of Ethernet technology in the field of industrial control, Ethernet / IP, as a new industrial Ethernet solution to solve the problems of low data transmission rate, lack of transparency, high software and maintenance costs in the network, has gained more and more attention. focus on. Ethernet / IP is a completely open technology, and this openness makes it popularized all over the world very quickly. Many large companies and research institutions at home and abroad see the business opportunities in this area and start researching one after another. [0003] Domestically, the research on Ethernet / IP communication interface is still in its infancy, ...
