Control Network trends towards using open, transparent communication protocol gradually, and at the ICP/IP protocol support of using on the Ethernet interconnected based between the heterogeneous network of xenogenesis operating system, be real open system communication protocol, become and carried out at present the interconnected de facto standards of heterogeneous network in the world.Its opening communication problem in industrial control field that makes obtains satisfactory solution.Because the Ethernet interface chip is very general, cheap, has used Ethernet as main communication interface in many industrial communications and automation application.
Briefly, Industrial Ethernet has following advantages:
Numerous advantages with commercial Ethernet, as: at a high speed, open, be widely used, technology maturation;
Instrument, the device network of the manufacturing network in the commerce Net of factory, workshop and field level is integrated;
In conjunction with the WEB function, make ecommerce, material supply chain and the ERP etc. of factory form unified integral body; The past Ethernet fails to enter industrial control field, mainly be because CSMA/CD (the Carrier Sense Multiple Access with Collision Detection that Ethernet adopts, the visit of CSMA/CD point) is a kind of uncertainty or randomness communication mode, can not satisfies the place user demand of the exigent Industry Control of real-time and certainty.But along with the continuous development of ethernet technology, its network transfer speeds improves constantly, and the network that bandwidth reaches gigabit occurred; And full duplex transmission and high speed switching technology also make the certainty of Ethernet and real-time problem be well solved, and after having overcome all deficiencies in the past, Ethernet enters the industrial circle nature, and when the water comes, a channel is formed.
Widely used in the world at present Industrial Ethernet standard has: the Modbus TCP of HSE (Fast Ethernet), the Schneider Electric exploitation of EtherNet/IP, the FF exploitation of RockwellAutomation and ODVA exploitation and the Profinet of Siemens exploitation, they are promoted by corresponding enterprise and tissue respectively and use.
Summary of the invention
The object of the present invention is to provide a kind of multi-protocol industry Ethernet Adaptation Unit, this adapter is useful in communication node, protocol converter, integrated circuit board and protocol gateway aspect, as interface product independently, realize the equipment access industrial Ethernet of band serial port, can be used as the cutting point of elevator system performance, realization system upgrade again.
For achieving the above object, technical scheme of the present invention is: its hardware comprises processor, ethernet controller, outer extension memory, serial ports controller, coupling separation filter, RJ45 interface, DB9 joint, DC power supply.Its software be comprise communication protocol software, based on the configuration software of PC,
Beneficial effect of the present invention: have Ethernet interface and serial port, the Ethernet side is supported Modbus/TCP and two kinds of agreements of EtherNet/IP simultaneously, the serial ports side is supported the Modbus rtu protocol, can be linked into Modbus/TCP or EtherNet/IP Industrial Ethernet to the field apparatus that has the Modbus interface, make equipment network more flexible, simplify and reduced the workload and the cost that original industrial equipment are linked into new Industrial Ethernet greatly, have certain economic to be worth and actual benefit.
Below in conjunction with drawings and Examples to the adapter of the present invention detailed description of making comparisons.
