In order to further specify actual operation flow process of the present invention, please refer to Fig. 3, utilize the embodiment process flow diagram of graphic operation setting for input/output module system of the present invention.Its step comprises: at first, the user connects signal generation device 2 and controlled device 3 earlier in input/output module 11, is step S301, and is able to carry out graphic monitoring sets interface 10 on computing machine 9, sets rule to produce figure, is step S303.Then, input/output module 11 is connected in computing machine 9, so that being received graphic monitoring, the rule treatments unit 110 in the input/output module 11 sets the figure setting rule that interface 10 is produced, be step S305, so, the input signal that the just further again received signal generation device 2 of input/output module 11 is produced, and set rule according to figure and change and computing, and then produce control signal and control the controlled device 3 that is connected, be step S307.
Refer again to Fig. 4, be Application Example synoptic diagram of the present invention.Present embodiment is to illustrate with controlling of factory's weighing check.Its environment for use is to suppose in the online conveying belt 4 of plant produced, and be provided with a pressure transducer 5 midway in conveying belt 4, and conveying belt 4 is that the running by a motor 6 drives running, and the power supply of whole conveying belt 4 is to switch switch 7 by one to control.Present embodiment mainly is in order to carrying out the QC check of a determinand T, and whether the weight that is used for detecting determinand T meets 100 kilograms, and the scope of allowable error is ± 1 kilogram.Wherein pressure transducer 5 is that the weight that is used for being measured is converted to voltage output, makes weight and voltage produce related (as: 100 kilograms is 5 volts of outputs, makes to be 4.95～5.05 volts when considering error range).
So the previous operations person of being to use connects pressure transducer 5 and change-over switch 7 respectively with the input block 111 of input/output module 11 earlier, the output unit 113 with input/output module 11 connects a motor 6 and an attention device 8 again.
And then, the user just formally the graphic monitoring on computing machine 9 set the operating and setting that interface 10 carries out diagram form, select to be set at the reception simulating signal with the input block 111 pairing input interfaces 101 that pressure transducer 5 is connected, and the input of further carrying out range of condition is set, and is set at 4.95～5.05 volts with the range of condition with the simulating signal input; And the input block 111 pairing input interfaces 101 that change-over switch 7 connects are selected to be set at receiving digital signals.Identical, the output unit 113 pairing output interfaces 104 that motor 6 connects are selected to be set at the output simulating signal, and the output that further is set at specific currents is with enough CD-ROM drive motor 6; And the output unit 113 pairing output interfaces 104 that attention device 8 connects are selected to be set at the output digital signal, and the generation that further is set at voltage is with activation attention device 8.
Moreover the symbol figure of selection representative " AND " computing in computing interface 102 down could be by the computing of computing interface 102 with the state that the signal of representing to be received must be set up at the same time.And in the present embodiment owing to for the better simply flow process of controlling, do not adjust and do not need to adjust interface 103 through state again, therefore state adjust only be set in the interface 103 unconditional by getting final product.At last, after setting was finished, the user sets the above-mentioned figure that setting produced the regular input/output module 11 that is loaded into again can make input/output module 11 carry out controlling of weighing check.
Then, because the power supply of whole conveying belt 4 must be opened, therefore when the user switched to the state of conducting (On) with change-over switch 7, the digital signal input DI that change-over switch 7 is produced was high levels signal (High), and the power supply of this expression conveying belt 4 is unlocked.This moment the determinand T that pressure transducer 5 can sensings enters weight, as if the pressure that is sensed by pressure transducer 5, and when the simulating signal input AI that is converted to voltage that incites somebody to action is 4.95～5.05 volts, input/output module 11 just can carry out " AND " computing behind digital signal input DI that receives and simulating signal input AI.And because digital signal input DI and simulating signal input AI both are the states that belongs to establishment, therefore just can to receive trigger pip be high levels signal and produce the control signal (being respectively digital signal output DO and simulating signal output AO) that sets through the user respectively to the output unit 113 in the input/output module 11, produce a caution effect and meet with the representative check and make digital signal output DO be controlled attention device 8, the AO of simulating signal output simultaneously is able to starter motor 6 determinand T to be transferred to next check outpost of the tax office with the running that drives conveying belt 4.
Opposite, when if input/output module 11 received digital signal DI or simulating signal AI one of them or both have incongruent state, after for example user's weight of change-over switch 7 not being switched to the determinand T that conducting state and/or pressure transducer 5 sensed is converted to voltage is not between 4.95～5.05 volts, pass through " AND " computing after in the input/output module 11 this moment, and generation then must be low level signal (Low) to the trigger pip of output unit 113.So, just can't make attention device 8 produce caution, simultaneously can starter motor 6 do not drive the running of conveying belt 4 yet.
In addition, when input/output module 11 is controlled the weighing check, also can be synchronously by response status signals with input/output module 11 at present performed to stage or the graphic monitoring that passes back in the computing machine 9 of state set interface 10, allowing other user be able on computing machine 9 to understand in real time present operation situation, and reach the effect of monitoring.
In sum, the present invention finishes the effect of setting the logic control rule by the operation of diagram form, not only can make input/output module initiatively carry out operation independent and handle.More can allow the user during input/output module is operating, be able to set interface and see the progress (comprising effects such as structure connected in series and feedback control) that whole rule is carried out in real time by graphic monitoring, and, more clearly provide with activation and select to set or even express real time status owing to be by patterned demonstration.Whereby, input/output module system not only can be reached have the purpose of enough simply adjusting control law, and made things convenient for and be applied to neatly among the various simple and easy monitoring environments.
But; the above; only be the detailed description and the accompanying drawing of specific embodiments of the invention; be not in order to restriction the present invention; protection scope of the present invention should be as the criterion with the protection domain of claims; any those skilled in the art in the field of the invention, can think easily and variation or modify all can be encompassed within the protection domain of this case.
