As shown in Figure 3, when the operational approach 30 of the HMI device of the embodiment of the present invention starts, firstFirst, in step S301, M viewing area of the display unit of described HMI device shows respectivelyFor the HMI of M controlled device, wherein M is the integer more than 1 and less than or equal to N.Connect, in step S302, detection user is for the control of the i-th viewing area in described M viewing areaSystem operation, wherein i is the integer more than 0 and less than or equal to M.Then, in step S303, according toI-th controlled device shown by described i-th viewing area is controlled by described control operation accordinglySystem.Hereafter, in step S304, receive the current operational information from described i-th controlled device, andDo not receive the current operational information of other controlled device.Then, in step S305, according to working as of being receivedFront operation information updates the display of the HMI on described i-th viewing area, and keeps other viewing areaDisplay constant.After performing step S305, the operational approach 30 of HMI device terminates.
In order to make it easy to understand, illustrate the operation of the HMI device shown in Fig. 1 below in conjunction with Fig. 4Each step of method 30.Fig. 4 (A) and Fig. 4 (B) is to illustrate HMI according to embodiments of the present invention respectivelyThe schematic diagram of the HMI display example of the operational approach 30 of equipment.Here, for convenience of explanation, stillAs in background section, assume that controlled device is PLC, and assume M=4.It should be noted thatThe situation that all controlled devices being intended to be connected HMI device as user monitor simultaneously and controlTime, N=M；And when user only needs that certain in the armamentarium being connected HMI device is several supervisesDepending on and control time, N > M.
Based on assumed above, as shown in Fig. 4 (A), in step S301, showing at described HMI deviceShow and show the HMI for 4 controlled devices respectively on 4 viewing areas of unit.Specifically, at HMIThere are 4 viewing areas 401,402,403 and 404 on the display unit of equipment, they are respectively intended toThe HMI of display PLC1, PLC2, PLC3 and PLC4.So, user can simultaneously monitor and controlPLC1, PLC2, PLC3 and PLC4.Specifically, generally comprise in the HMI of each controlled deviceThe current operational information of controlled device and control knob etc., thus user can pass through current operational informationMonitor the current operating conditions of controlled device, and by the operation of control knob etc. is come controlled deviceIt is controlled.
As shown in Fig. 4 (A), in the HMI for each controlled device, such as with being labeled as letterThe rectangle of sum combinatorics on words and the oval current fortune representing the element shown in HMI, i.e. controlled deviceRow information and control knob etc..Such as, in for the viewing area 401 of PLC1, PLC1 is shownCurrent operational information A1, A2 and control knob A3, show in for the viewing area 402 of PLC2Go out the current operational information B2 of control knob B1 and PLC2, in the viewing area 403 for PLC3In show current operational information C1, C2 and control knob C3 and C4 of PLC3, and forThe viewing area 404 of PLC4 shows current operational information D1, D2 and the control knob of PLC4D3 and D4.
It should be noted that represent in HMI with difformity, the most different size of geometirc illustrationThese elements are to show in each HMI that shown element can concrete according to different controlled devicesSituation and different.Such as, control knob can be designed as rectangle or ellipse etc..The most such as, controlled setStandby current operational information can be to be the form such as text, picture, and picture occupied area is likely to bigger than text,Etc..Therefore, above-mentioned geometirc illustration is merely exemplary, does not limits the invention.
Assume that user is intended to by being operable to the control knob A3 in viewing area 401 to PLC1It is controlled, say, that, it is assumed that i=1.Therefore, in step S302, user is for the 1st in detectionThe control operation of viewing area 401.Here, when the display unit of HMI device is touch sensitive display unit,The operation of control knob A3 such as can be passed through finger directly on touch sensitive display unit by user by userClick on this control knob A3 to realize.Or, the display unit at HMI device is not to touch display listDuring unit, user such as can also be by the such as mouse etc. of HMI device to the operation of control knob A3Other input equipment realizes.
After step S302 detects that user is for the control operation of the 1st viewing area 401, in stepRapid S303, controls the 1st controlled device PLC1 accordingly according to described control operation.SpecificallyGround, HMI device according to detected user to operation button A3 operation, such as can by willOperation information about this control operation sends to PLC1 to control PLC1 accordingly.
Now, in step S304, HMI device receives the current fortune from the 1st controlled device PLC1Row information, and do not receive the current operational information of other controlled device.Then, in step S305, HMIEquipment is aobvious according to the HMI's on described 1st viewing area 401 of current operational information renewal receivedShow, and keep the display of other viewing area constant.Fig. 4 (B) further illustrates after step S305Content shown on the display unit of HMI device.
Specifically, by compared with Fig. 4 (B) and Fig. 4 (A) it is seen that, owing to HMI device passes throughStep S305 and step S306 have received the current operational information of PLC1 and according to deserving from PLC1Viewing area 401 for PLC1 is updated by front operation information, so in viewing area 401The element of display there occurs change.Such as, the operation information A2 of original PLC1 shown in Fig. 4 (A)With current operational information A4 and the control knob that control knob A3 has become the PLC1 shown in Fig. 4 (B)A5 and A6.But, due to HMI device in step s 304 not from other three controlled device PLC2,PLC3 and PLC4 receives current operational information, and therefore in step S305, HMI device keeps otherThe display of three viewing areas 402,403 and 404 is constant, i.e. viewing area 402 in Fig. 4 (B),403 is identical with Fig. 4 (A) with the element shown in 404.
As can be seen here, by the operational approach of above-described HMI device according to embodiments of the present invention30, when some controlled device is only controlled by user, the only display information of this controlled device occursChange, and the display information of other controlled device will not change.It is thus possible at same HMI deviceThe while of upper and monitored independently of one another and controlled multiple controlled device, it is simple to user operation.
Above, shown in Fig. 4, give the operation by using the HMI device shown in Fig. 3Method 30 on same HMI device simultaneously and monitor independently of one another and control multiple controlled deviceConcrete example.Should be understood that the value of above M and i is merely exemplary, the invention is not restricted to this.
