Compare with other field bus system, the great advantage of PROFIBUS is to have stable international standard EN50170 and guarantees, and has generality through the practical application checking.The field of having used at present comprises processing and manufacturing. process control and automation etc.Market survey confirms, PROFIBUS accounts for the market of open industrial field bus system above 40% in Germany and European market.
In the development﹠ testing of PROFIBUS-DP equipment, adopt the PROFIBUS communication card usually, this PROFIBUS communication card is installed on the PCI groove of PC, thus realize with its slave station (or main website) equipment between communicate by letter.
Yet, in the aforesaid way, not only use inconvenience, and input cost height (a PROFIBUS communication card needs several thousand yuan).In addition, produce the manufacturer's test inconvenience with this kind communication function module, test is slow, and efficient is low, the cost height.
The utility model content
The technical problems to be solved in the utility model is, at above-mentioned employing PROFIBUS communication card cost height, awkward problem, provides a kind of testing apparatus of the PROFIBUS-DP of simulation master station communication.
The technical scheme that the utility model solves the problems of the technologies described above is, a kind of testing apparatus of the PROFIBUS-DP of simulation master station communication is provided, comprise the computer with RS232 communication port, the adapter that is used for RS232 port commentaries on classics RS485 port and the host computer unit that is used to use realization of RS485 communication protocol and PROFIBUS-DP communication apparatus communication, described adapter is connected to the RS232 communication port, and described host computer unit is positioned at described computer.
In the testing apparatus of simulation PROFIBUS-DP master station communication described in the utility model, described adapter is connected to the PROFIBUS-DP communication equipment by twisted-pair feeder.
In the testing apparatus of simulation PROFIBUS-DP master station communication described in the utility model, described adapter is independent of described computer and is plugged into the RS232 communication port by serial ports.
In the testing apparatus of simulation PROFIBUS-DP master station communication described in the utility model, described adapter is built in the case of computer and port exposes case of computer.
The testing apparatus of implementing simulation PROFIBUS-DP master station communication of the present utility model has following beneficial effect: by adapter and host computer unit, realized and the communicating by letter of PROFIBUS-DP communication equipment, the development﹠ testing cost of PROFIBUS-DP equipment can be effectively reduced, and production test efficient can be significantly improved.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of testing apparatus first embodiment of simulation PROFIBUS-DP master station communication of the present utility model;
Fig. 2 is the schematic diagram of testing apparatus second embodiment of simulation PROFIBUS-DP master station communication of the present utility model;
Fig. 3 is the schematic diagram of application of the testing apparatus of simulation of the present utility model PROFIBUS-DP master station communication.
Embodiment
All attached the RS232 serial communication interface on the general computer, in order to satisfy RS485 communication protocol and physical layer, the utility model is adding on the RS232 serial communication interface that a RS232 changes the adapter of RS485 and (has a lot on this adapter market, and it is very cheap), realize transition of communications by upper computer software simultaneously, thereby realized and the communicating by letter of PROFIBUS-DP equipment, can directly apply to the development﹠ testing of PROFIBUS-DP equipment.
As shown in Figure 1, be the schematic diagram of testing apparatus first embodiment of simulation PROFIBUS-DP master station communication of the present utility model.In the present embodiment, the testing apparatus of simulation PROFIBUS-DP master station communication comprises computer 11 and adapter 14, wherein computer 11 includes RS232 communication port 12 and upper computer software 13, and adapter 14 is plugged on the RS232 communication port 12.
As shown in Figure 2, be the schematic diagram of testing apparatus second embodiment of simulation PROFIBUS-DP master station communication of the present utility model.In the present embodiment, the testing apparatus of simulation PROFIBUS-DP master station communication comprises computer 21 equally, and different with first embodiment is that adapter 23, RS232 communication port 22 and upper computer software 24 all place in the computer 21.
As shown in Figure 3, be the schematic diagram of application of the testing apparatus of simulation of the present utility model PROFIBUS-DP master station communication.Control end 31 (for example computer shown in Fig. 1 or 2 and adapter) is connected to PROFIBUS-DP communication equipment 32 by twisted-pair feeder, and wherein at control end 31, the twisted-pair feeder interface is plugged into transducer.
Because PROFIBUS communication protocol mode is communicated by letter identical with general RS485, it provides RS485 port physical layer working method, use identical physical medium (RS-485/FO) because of FMS/DP again, so the utility model is combined in the order wire that has also therefore saved special-purpose PROFIBUS-DP card and the sort of costliness of other I/O mouth on the same cable with them.
