Abstract
The utility model relates to an industrial network communicator which comprises an analog digital conversion interface, a communication interface and a central processing unit, wherein the analog digital conversion interface is connected with the central processing unit by a parallel interface, and the communication interface is connected with the central processing unit by a parallel interface. The utility model is characterized in that the central processing unit is also connected with a communication protocol conversion board by the communication interface; the communication protocol conversion board is also connected with a PROFIBUS protocol module by a MODBUS communication protocol. The utility model solves the problem of the communication of a Profibus-DP industrial bus, supports the seamless connection with Simens PLC, and realizes the two-way communication of data. The CPU in the MSP 430 series is used as the central processing unit so that the equipment is compact and flexible. The utility model also has the advantages of low cost, easy commercialization, strong interference resistance capacity and wide applicable temperature range. The utility model can reliably work under various adverse conditions, and can conveniently realize multi-machine and distributed control.
Description
Technical field
The utility model belongs to the device that interconnects between a kind of different industrial network, is a kind of industrial network communicator specifically.
Background technology
Quite extensive with the PLC headed by the Siemens, DCS application at present, the Profibus-DP fieldbus of its support is also quite universal.The various devices that supplier provided such as the various transducers of domestic rise, actuator, secondary meter are also replaced the relevant device of external import gradually, but support not enough to the interface that bus connects.
Summary of the invention
The purpose of this utility model provides and a kind ofly makes various relevant devices can hang up the Profibus-DP fieldbus easily, realizes the industrial network communicator of the intercommunication of data, to remedy the deficiencies in the prior art part.
To achieve these goals, the utility model is made of analog-to-digital conversion interface, communication interface and central processing unit, its analog-to-digital conversion interface links to each other with central processing unit by parallel interface, communication interface is connected with central processing unit by serial line interface, is characterized in: central processing unit also is connected with the communications protocol change-over panel by communication interface.
Above-mentioned communications protocol change-over panel also is connected with the PROFIBUS protocol module by the MODBUS communications protocol.
The utility model solves the communication problem in the Profibus-DP industrial bus, supports and the seamless link of Siemens PLC C, realizes the two-way intercommunication of data.Utilize MSP430 series CPU as central processing unit, make that equipment is small and exquisite flexibly, cost is low, be easy to commercialization, and antijamming capability is strong, the adaptive temperature wide ranges, under various adverse circumstances, can both work reliably, can realize multimachine and distributed control easily.The utility model is mainly the practical application of energy data volume crossing and develops, and it is little to possess volume, and antijamming capability is strong, and is easy for installation, the characteristics that ability to communicate is strong.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
The utility model is made of analog-to-digital conversion interface, communication interface and central processing unit, its analog-to-digital conversion interface links to each other with central processing unit by parallel interface, communication interface is connected with central processing unit by serial line interface, central processing unit also is connected with the communications protocol change-over panel by communication interface, and the communications protocol change-over panel also is connected with the PROFIBUS protocol module by the MODBUS communications protocol.
As shown in Figure 1, digital quantity input and analog quantity input peripheral interface equipment convert the parallel port signal of digital quantity to by the analog-to-digital conversion interface, insert the MSP430 central processing unit; Another possesses the ancillary equipment of RS485 digital quantity communication interface then by RS232 and the translation interface realization of RS485 and docking of central processing unit MSP430, digital quantity signal after central processing unit MSP430 changes these carries out processed, be sent to HMS/3000 communications protocol change-over panel by other one road RS232 private access, data are sent in the data buffer zone of HMS/3000 according to the MODBUS communications protocol of simplifying version, be responsible for the driving of PROFIBUS agreement by HMS/3000, finish and the communication that possesses the PLC/DCS of PROFIBUS ability to communicate.
The utility model address dial-up adopts decimal system mode, and an address high position is metric ten, and the address low level is metric position.For example: the high-order dial-up in address is 6, and address low level dial-up is 3, and then Shi Ji device address is metric 63.The effective address scope is: 0～99 (0～63H).The utility model working power is DC24V, the about 40mA of individual module electric current demand is necessary in order to allow module energy steady operation suitably leave certain power supply surplus, the DC24V power supply can be the power supply that this machine of PLC carries, but must guarantee the necessary power supply capacity of PLC work, also can be other DC power supply (as using switching power supply) of autogamy, must guarantee power supply quality (as selecting the few industrial stabilized voltage power supply of high-quality of the little electromagnetic radiation of ripple).
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
