At present, at PLC switch board design field, while checking and accepting PLC switch board, need two people to coordinate and carry out verification, people short-circuited terminal after switch board is arranged, and another person observes and shows result before switch board.This method, in checking procedure, often because two people before and after switch board understand differently to be caused, cause verification to leak item or check errors, and two is difficult for realizing per capita.Meanwhile, this method of calibration has consumed a large amount of time, work efficiency is reduced, and have some verify errors, and accuracy rate is low.
Utility model content
The inefficiency and the low technical matters of accuracy rate that in order to solve existing method of calibration, exist, the utility model provides a kind of PLC cabinet IO point calibration equipment and method of calibration thereof.
The technical scheme that the utility model technical solution problem is taked is as follows:
A PLC cabinet IO point calibration equipment, comprises cabinet, touch-screen, electric power incoming line plug, Switching Power Supply and plc communication cable; Touch-screen is arranged on the front panel of cabinet, and Switching Power Supply is arranged on the inside of cabinet; Electric power incoming line plug is arranged on the side panel of cabinet, and is connected with Switching Power Supply, and electric power incoming line plug is touch-screen power supply by the 220V alternating current of access after Switching Power Supply is converted to 24V direct current; The PORT COM of touch-screen is connected with plc communication cable, and guides to the side of cabinet; Touch-screen is connected with PLC by plc communication cable, the check results of touch-screen for showing that each I/O of PLC to be verified is ordered.
The beneficial effects of the utility model are: this equipment, when verification PLC cabinet, only needs a people can complete verification task, and not only work efficiency is high, but also can avoid the generation of various check errors, and accuracy rate is high.
Accompanying drawing explanation
Fig. 1 is that the utility model PLC cabinet IO point calibration equipment removes cabinet top cover structural representation afterwards.
Fig. 2 is the verification view of switching value in the utility model.
Fig. 3 is the verification view of analog quantity in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
As shown in Figure 1, PLC cabinet IO point calibration equipment of the present utility model comprises that cabinet 1, touch-screen 2, electric power incoming line plug 3, Switching Power Supply 4 and two ends are with the plc communication cable 5 of attachment plug; Touch-screen 2 is arranged on the front panel of cabinet 1, and Switching Power Supply 4 is arranged on the inside of cabinet 1; Electric power incoming line plug 3 is arranged on the side panel of cabinet 1, and is connected with Switching Power Supply 4, and electric power incoming line plug 3 is touch-screen 2 power supplies by the 220V alternating current of access after Switching Power Supply 4 is converted to 24V direct current; The PORT COM of touch-screen 2 is connected with plc communication cable 5, and guides to the side of cabinet 1; Touch-screen 2 is connected with PLC by plc communication cable 5, the check results of touch-screen 2 for showing that each I/O of PLC to be verified is ordered.During use, the PLC of every type is connected on touch-screen 2 by the plc communication cable 5 of corresponding types separately.
The method of calibration of PLC cabinet IO point calibration equipment comprises the steps:
The first step, according to the type of PLC to be verified, select the configuration program in notebook computer; The process of establishing of described configuration program is: first according to the actual configuration parameter of PLC to be verified, count that switching value input is counted, switching value output is counted, analog input is counted and analog output is counted; Then design switching value display frame, each switching value input/output point form with pilot lamp on this picture is shown; Last design simulation amount display frame, shows each analog input/output point form with percentage on this picture;
Second step, notebook computer is connected with touch-screen 2 by plc communication cable 5, and calibration equipment is switched on;
The 3rd step, until the picture of touch-screen 2, enter under program and fill after picture, will under the selected configuration program of the first step, install in touch-screen 2;
After installing under the 4th step, configuration program, calibration equipment power-off, and take off touch-screen 2 is connected use plc communication cable 5 with notebook computer;
The 5th step, PLC to be verified is connected on touch-screen 2 to calibration equipment energising by plc communication cable 5;
The 6th step, according to Practical Project requirement, successively the I/O point of PLC to be verified is carried out to verification, assay is directly presented on touch-screen 2.
Embodiment:
As shown in Figures 2 and 3, take Siemens PLC as example, touch-screen 2 adopts MT508S model touch-screen, and Switching Power Supply 4 adopts 6EP1332-1SH42 model, and plc communication cable adopts Siemens 6ES7972-0CB20-0XA0 model Programme Line.Software configuration: configuration picture on touch-screen 2, thereby the I/O state of demonstration PLC.
PLC for SIEMENS S 7-200 number: designer is according to the experience of a plurality of engineerings, and each I/O point quantity that designs this PLC is as follows:
Digital quantity input DI 24 points;
Digital output DO 16 points;
Analog input AI 20 points;
Analog output AO 1 point.
PLC for Siemens S7-300 model: designer is according to the experience of a plurality of engineerings, and each I/O point quantity that designs this PLC is as follows:
Digital quantity input DI 96 points;
Digital output DO 32 points;
Analog input AI 32 points;
Analog output AO 1 point.
PLC for Siemens S7-400 model: designer is according to the experience of a plurality of engineerings, and each I/O point quantity that designs this PLC is as follows:
Digital quantity input DI 128 points;
Digital output DO 32 points;
Analog input AI 32 points;
Analog output AO 2 points.
The selection picture of PLC model is set on touch-screen 2, and disparity items enters the I/O effect picture of different PLC.Wherein, DI and DO point be take pilot lamp as state demonstration, and this verification of the bright expression of pilot lamp is qualified, and pilot lamp goes out and represents that this verification is defective; AI and AO o'clock be take 0～100% numerical value as effect value, and numerical value is that this verification of 0 expression is defective, and numerical value is that correct percentage represents that this verification is qualified.
