2 " the BOs relevant with " control "：Individually hair stops " and " AO：Simulation output " is to be related to controlling element in management project When the signal that is exported from PLC to controlling element.It is " BO when the signal is binary data signal：Individually hair stops ".BO=1 It is to make the signal that the action as the controlling element of object is started, BO=0 is to make the action stopping as the controlling element of object Signal.As the example of " BO " signal be heater on-off, illumination on-off, the on-off of air-conditioning, electricity The on-off in source etc..It is " AO when the signal exported to controlling element is analog signal：Simulation output ".It is used as " AO " signal Example be the continuous variable opening and closing signal of valve, dim signal, the temperature command signal of air-conditioning etc. of illumination.

" BI ", " AI " relevant with " monitoring " is that PLC is inputted from monitoring key element when management project is related to monitoring key element Signal.It is " BI " when the signal is binary data signal, is " AI " when the signal is analog signal.

" BI " represents the state of monitoring key element, and when BI=1 represents the state that monitoring key element is being acted, BI=0 represents prison Depending on key element action stop when.Although " BI " is pulse signal, exist and carried out " metering " by counting the pulse signal Monitor key element.Such as ammeter, water meter, gas meter, flow meter.These tables measure its consumption by plectane or annulus rotation.By each One pulse of secondary rotation output carrys out count pulse number, " can measure " their consumption.In other words, ammeter, water meter, gas meter, flow meter Deng not monitored using analog signal, but monitoring is measured using umber of pulse of the pulse signal in binary " BI " 's.The column of " state " and " metering " of " BI " is the input of identical binary signal, still, and whether be used to distinguish in PLC needs Want count pulse number.In other words, if monitoring key element is " instrument " class, zero mark is charged on " metering " column, be not " instrument " During class, zero mark is charged on " state " column.

" AI " is voltage signal or current signal, and temperature is measured by measuring resistance.As described later, " AI " is in PLC In be transformed into data signal from analog signal and send PLC00 to, still, for " Current Voltage " analog signal and " resistance " Analog signal, it is different to the translation circuit of data signal.Therefore, for the classification of the input-output equipment relevant with " AI ", The input-output equipment relevant with " Current Voltage " is expressed as " AI ", the input-output equipment relevant with " resistance " is expressed as " AI-R ", so as to distinguish both.

Return to Fig. 4, when in 46 display management project blank table 31 of display part, the designer of PLC system 10 according to The relevant basic enterprise planning book of the management systems of building 8, by with the controlling element of building 8 and information that to monitor the whole of key element relevant It is input to management project blank table 31 (S22).Designer is carried out to management item on the picture of display part 46 by manually entering The input of mesh blank table 31.In the flow chart of figure 4, the step of showing to be performed by servicing unit 40 in each step with solid box, The step of picture for being shown by the dashed box designer and display part 46 is carried out by the manually input of dialogic operation.This is for aftermentioned Flow chart be also same.

On the input to management project blank table 31, filled in for a controlling element or monitoring key element on worksheet 1 row.For example, it is assumed that when the 7th row fills in a monitoring key element, the name of the monitoring key element is charged in " management project title " Claim, the office number that will handle the PLC of the monitoring key element charges to " PLC innings numbers ", the title that will store the RS plates of the PLC charges to " RS plates Title ".Then, it is determined that the classification for the signal for being input to PLC from monitoring key element is binary data signal or analog signal. When being data signal, judgement is " metering " of " BI " " state " or meters, and zero mark is charged in any column.It is being During analog signal, judgement is " Current Voltage " or temperature detection " resistance ", and zero mark is charged in any column.

To management project blank table 31 inputs multiple controlling elements, the input sequence of multiple monitoring key elements can be any , the management project table 32 of generation is submitted into owner, plate business, Program Generating business etc., thus the arrangement preferably easily to observe Inputted.One of method is to enter the information relevant with monitoring key element with whole controlling elements according to basic enterprise planning secretary first, Then changed with behavior unit and put in order and turn into the arrangement easily observed." again using number " whenever the replacing is carried out from Dynamic change, so that the beginning side of row is less numbering.

" management project " in the sum and building 8 of the quantity of RS plates, PLC quantity by designer according to " management project " Configuration state set.As an example, in the case of figure 1, the sum of " management project " is 350 (reference pictures 11) to row.8 In the case of the PLC of individual slot, if respectively ensuring the slot and standby slot of a communication, can using 6 slots as Input-output equipment is used.If using the standard device that port number is 16 as input-output equipment, the energy in a PLC Enough handle about 100 " management project ".In the case where the sum of " management project " is 350, PLC quantity needs to be 4.

RS plates can store multiple PLC, it is thus possible to store 4 PLC in RS plate, if by the RS plates and RS-0 mono- Play configuration and be configured with the BF of central monitoring device 12, then it is most short that can make network layout.On the other hand, self-configuring is for example carried out Turn into the length from 5F to BF in 5F controlling element and the signal wire of monitoring key element.The quantity of signal wire is at least " management item The quantity of mesh ", thus in the case of figure 1, add up at least 350 signal lines in the laid inside of building 8.Compare laying 350 5 network layouts of signal line and laying, in terms of the cost and from the aspect of signal transmits, particularly preferred the latter.It is therefore preferable that RS plates are dispersed in building 8 and one is not set to.So, it is considered to the setting such as the sum of " management project " and the construction of building 8 The quantity of RS plates and PLC quantity.It is set to the configuration of RS plates in Fig. 1 PLC system 10 in each layer, one is stored in each RS plates Individual PLC.

When the information relevant with all " management project " of the completion in the management project blank table 31 for be shown in display part 46 During input, S22 processing terminates.Fig. 6 shows the example of the management project table 32 manually entered.As described above " management project " Sum be 350, thus one part is illustratively shown in figure 6.Here, showing the different example of the classification of input/output signal Son.For example, showing a part for 150 " management project " that " PLC innings numbers " are 01 in the row of 7 rows~156, these management projects are complete Portion is " BI ", wherein including " state " and " metering ".The row of 157 rows~162 is one that " PLC innings numbers " are 03 " management project " Point, it is the example of " AO ".The row of 246 rows~252 is the part that " PLC innings numbers " are 05 " management project ", is the example of " AI-R " Son.

To at the end of being shown in the manually input of management project blank table 31 of display part 46, designer be shown in it is aobvious Show in " file " label of picture upper side in portion 46, pressed in the call buttons relevant with multiple groups " being registered in database " Button (S24).Fig. 7 shows multiple call buttons 64,66,68,70 in " file " label.Press wherein and " be registered in data The call buttons 64 in storehouse ".Thus, servicing unit 40 is to the additional title of management project table 32 manually entered on display part 46 And storage is registered to management project table database 50 (S26).More than, the processing (S10) of management project table registration terminates.

Fig. 8 is the flow chart for the specific steps for showing the processing (S12) of PLC structural table editors.In the registration of management project table Processing (S10) terminate state after perform S12.In order to start the processing of PLC structural table editors, designer is in the more of file " selection PLC " (S30) is clicked in individual call buttons.Specifically, click on file shown in Fig. 7 multiple call buttons 64, 66th, in 68,70 " selection PLC " 66 (clicks on 1).Thus, servicing unit 40 shows PLC Blank space of construction table 33 in display part 46 (S32).Fig. 9 is the figure for the view data for showing PLC Blank space of construction table 33.Below, by the view data of PLC Blank space of construction table 33 Referred to as PLC Blank space of construction table 33.PLC Blank space of construction table 33 and management project table 32 are same, are also by by multiple rows and multiple The worksheet of multiple cell arrangements as defined in row.The display of line number and row number is eliminated in fig .9.

PLC Blank space of construction table 33 has the basic specification columns of PLC, PLC structures column and beginning XY allocation rules, true as charging to The title bar of fixed PLC item and 3 columns for representing PLC structures.

" subsystem " in title bar is the title of the subsystem of PLC processing." system " is the connection PLC00 and PLC Underlying network systematic name.

The basic specification columns of PLC are to be configured at the table column above right side in fig .9." basic " is represented for constituting " inserting for PLC The model name of seat ", the model name of " power supply " and " slot count ".In PLC Blank space of construction table 33, " socket " is initially set It is set to " BS8 " of standard, " power supply " is initially set to " PS-S " of standard." BS8 " is the socket that slot count is 8, " PS-S " Represent the power supply that power supply capacity is standard.It is " BS8 " linkage with " socket ", " slot count " is " 8 ".Designer can be according to connecting The PLC relation to square plate is connected to, the setting beyond initial setting is altered to.For example, needing the larger " electricity of power supply capacity During source ", power supply capacity larger " PS-L " can be altered to.When thinking increase " slot count ", use and " set up 1 " column and set up " slotting Seat ", can correspondingly increase " slot count ".Although setting change can be carried out by manually entering, but it is also possible to take And instead of, next candidate is shown when clicking on " socket ", " power supply ".

It is corresponding with " slot count " set in the basic specification columns of PLC in the PLC structures column for being configured at left side in fig .9 Ground, shows " slot " of 8 rows.The classification for the equipment for being configured at each slot is charged in " classification " column, in " model name " column Charge to the title of equipment.The port number of equipment is charged in " points " column, " is starting in XY " columns and is charging to the passage pair with equipment The beginning address of " CPU " that answers." CPU " described herein refers to " CPU " shown in the PLC structural tables.

In PLC Blank space of construction table 33, as initial setting, in CPU slot configurations model name " QCPU15k " conduct " CPU " equipment, model name " QCCL " conduct " communication " equipment is configured in slot=0." Q " in these model names is integrated The meaning of circuit, " QCPU15k " represents the CPU integrated circuits that memory capacity is 15k grades." QCCL " is represented in management project table Reflect that " backbone " is " CCL " and is adaptable to the communication integrated circuit of CCL communication network in 32.The port number of " QCCL " is " 32 ", thus " points " are initially set " 32 ".In addition, when with reference to " the beginning XY allocation rules " described below, will The beginning address of " CCL " is set to " 3E0 ", thus " beginning address " relevant with " QCCL " is initially set " 3E0 ".

Designer can change the initial setting of " model name " of " CPU ".For example, in view of needing memory capacity When being set to 40k grades, " model name " change of " CCL " is set as " QCPU40k ".Although can be carried out by manually entering Setting change, but it is also possible to instead, next candidate be shown when clicking on " model name " of " CPU ".

" the beginning XY allocation rules " column for being configured at lower right-hand side in fig .9 is " CPU " corresponding with the passage of each equipment Beginning address.The model name of " CPU " is " QCPU15k ", thus according to the rule by the address of " CPU " of the model name Distribute to the passage of each equipment.Address is 16 bit bases, is needed when generating PLC program.

For example, when input-output equipment is " BO " equipment, distribution represents the address of 3 behind " Y " of output.Will beginning Address is set to 0~F0, thus distributes " BO " equipment for being configured at slot=1 the beginning address of " Y000 ".Set in input and output During for being " AI " equipment, distribution represents the address of 3 behind " X " of input.First beginning address is 300, thus to configuration " AI " equipment in slot=1 distributes the beginning address of " X300 ".

At the end of content check in PLC Blank space of construction table 33, change of initial setting if necessary etc., designer presses The Next button in the picture corner (not shown) for being shown in display part 46 in Fig. 9.Thus, auxiliary program enters next place Step is managed, the selecting switch into PLC innings numbers is shown (S34) in fig. 8.

In S34, servicing unit 40 shows the view data of the selecting switch of PLC innings numbers in the picture of display part 46. In Fig. 10, as display PLC innings numbers selecting switch view data example, selecting switch image 80 is shown.Show herein Show " 00 "~" 05 " of PLC innings numbers, but with halftoning shows the content of reflection management project table 32 and in management project table 32 In " 00 " that does not occur so that can not select.As PLC innings numbers selections (S36), when selecting PLC01, designer presses " 01 " Selecting switch.Thus the selection of PLC innings numbers is carried out, therefore, designer, which presses, (not shown) in Figure 10 is shown in display part 46 Picture corner Next button.

Thus, auxiliary program enters next process step, and in fig. 8, servicing unit 40 is managed project table data The retrieval (S38) in storehouse 50, servicing unit 40 is according to each input/output signal classification management of computing item number (S40).In this place Manage in step, management project table 32 is read from management project table database 50, using PLC innings numbers=01 as the 1st search key, Using the of all categories as the 2nd search key of input/output signal, the number of all categories of input/output signal is calculated PLC01 Amount.In the picture that the result calculated is shown in display part 46.

As reference, in whole PLC innings numbers, according to each input/output signal classification, figure 11 illustrates each input The result of calculation of the quantity of output signal.Figure 11 longitudinal axis is PLC innings numbers and its related information, and Figure 11 transverse axis is input and output The classification of signal is " BO ", " AO ", " BI ", " AI ", " AI-R "." BO ", " AO ", " BI " are the F row of Fig. 6 management project table 32 " BO ", " AO ", " BI " of~I row, " AI " is J row " AI：Supply voltage ", " AI-R " is K row " AI：Resistance ".

Describe the example that the quantity of input/output signal is calculated.As first case, in PLC01, in order to calculate " BI " Signal number, using PLC innings numbers=01 as the 1st search key, using input/output signal=" BI " as the 2nd search key, Retrieve Fig. 6 management project table 32.As a result, cell number=150 of hit, thus " BI " is calculated in PLC01 Signal number is 150.As second case, in PLC03, in order to calculate the signal number of " AO ", the 1st inspection is used as using PLC innings numbers=03 Rope keyword, using input/output signal=" AO " as the 2nd search key, retrieves Fig. 6 management project table 32.Its result It is, cell number=12 of hit, thus it is 12 to calculate in PLC03 the signal number of " AO ".As the 3rd, in PLC05 In, in order to calculate the signal number of " AI-R ", using PLC innings numbers=05 as the 1st search key, by input/output signal=" AI- R " retrieves Fig. 6 management project table 32 as the 2nd search key.As a result, cell number=10 of hit, thus meter The signal number for calculating in PLC05 " AI-R " is 10.

In Fig. 10, PLC innings numbers=01 is selected, thus shows in the picture of display part 46 Figure 11 PLC01 calculating As a result a part.When observing the result, " BI "=150, other " BO ", " AO ", " AI ", " AI-R " they are entirely that input is defeated Go out quantity=0 of signal.Designer carries out the confirmation of the result, presses the Next button on picture.Thus, auxiliary program Into next process step, in fig. 8, the setting (S42) of input-output equipment is entered with reference to input-output equipment list.

Input-output equipment list be by with the classification of input/output signal i.e. " BO ", " AO ", " BI ", " AI ", " AI-R " The model name of corresponding input-output equipment is included in the table in table respectively.Standard type is the equipment in port number=16 In, " BO " and " BI " has port number=32,64.The input-output equipment of analog signal includes analog digital converter or number Word analogue converter, consequently only that port number=16.Below, as the model name of input-output equipment, for " BO " and The item name and port number of input/output signal are combined by " BI ", be expressed as " BO16 ", " BO32 ", " BO64 ", “BI16”、“BI32”、“BI64”.Also, for " AO ", " AI ", " AI-R ", it is expressed as and input/output signal identical “AO”、“AI”、“AI-R”。

In S42, servicing unit 40 carries out the setting of input-output equipment according to the following steps.First, reference picture 11 By " BO ", " AO ", " BI ", " AI ", " AI-R " input/output signal number divided by 16, obtain " BO ", " AO ", " BI ", " AI ", The quantity of " AI-R " respective input-output equipment.In PLC01, the quantity of relevant input-output equipment is with " BI " (150/16)=9.375, quantity=0 of the input-output equipment relevant with other input/output signals, thus PLC01 needs The classification and its quantity of input-output equipment are that " BI " is 10.

When obtaining the sum of input-output equipment of needs, by the sum with input and output can be distributed in PLC The slot count of equipment is compared.In the case of PLC01, can distribute to input-output equipment is slot=1~slot =6 this 5.When result of the comparison is (slot count that can be distributed) >=(sum of the input-output equipment needed), according to Each input-output equipment of order-assigned of slot=1~slot=6.It is (slot count that can be distributed) in result of the comparison<(need The sum for the input-output equipment wanted) when, for " BO ", " BI ", determine whether to be applicable the defeated of 32 port numbers or 64 port numbers Enter output equipment.In the case of PLC01, due to (slot count that can be distributed)<(sum of the input-output equipment needed), Therefore, determine whether to be applicable " BI32 " of 32 passages first for " BI ".When being applicable " BI32 ", (input and output needed are set Standby sum)=(150/32)=4.6875, thus " BI32 " need to be 5.It is being set to (slot count that can be distributed)=6 When being compared, (slot count=6 that can be distributed)>(sum=5 of the input-output equipment needed).But, as standby And the slot count prepared is (6-5)=1 slot.When standby slot number is set as into " 2 " in advance, (the slot that can be distributed Number)=4, even if thus be applicable " BI32 ", be also (slot count=4 that can be distributed)<(the sum of the input-output equipment needed =5).Therefore, then determine whether to be applicable " BI64 ".In this case, (sum of the input-output equipment needed)= (150/64)=2.34375, thus " BI32 " is 3.Now, (slot count=4 that can be distributed)>(input needed is defeated Go out the sum of equipment=3).As a result, " BO64 " is set as into 3 for PLC01 input-output equipment.

The setting procedure of above-mentioned input-output equipment be only intended to explanation example, in addition the step of, only Use and expect number the need for the standby slot count that can be distributed, each input-output equipment of result of calculation based on Figure 11 With the list of input-output equipment.

When carrying out the setting of input-output equipment in S42, servicing unit 40 is carried out to PLC Blank space of construction table 33 accordingly The distribution (S44) of input-output equipment.In the case of PLC01, " BI64 " is distributed respectively to slot=01~slot=03.So Afterwards, with reference to " beginning XY allocation rules ", the beginning XY addresses of BI equipment are " X100 ", thus " BI64 " of slot=01 is distributed The beginning XY addresses of " X100 ".For " BI64 " of slot=02, " 20 " of 16 bit statement corresponding with 64 passage amounts of staggering And " X140 " is distributed, distributed " X180 " for " BI64 " of slot=03, " 20 " of the 64 passage amounts that further stagger.

The result being allocated is shown in the picture of display part 46 by servicing unit 40 as the PLC structural tables 34 after editor (S46), and store arrive management project table database 50.Thus, the process step of PLC structural tables editor terminates.

In above-mentioned example, the editor of the PLC structural table 34 relevant with PLC01 terminates, be then able to carry out with it is other The editor of PLC structural tables 34 relevant PLC02~PLC05.In this case, S12 is returned to, is repeated from S30 Process step.Instead, also can after the editor of the PLC structural table 34 relevant with PLC01 terminates, continue for The input-output equipment edited in PLC01 PLC structural tables 34 carries out PLC input/output lists editor (S14).Below, explanation is pressed Method according to the latter carries out the PLC input/output list editor relevant with the input-output equipment in PLC01 PLC structural tables 34 (S14) the step of when.

Figure 13 is the flow chart for the specific steps for showing the processing (S14) of PLC input/output list editors.In PLC structural tables S14 is performed after the state that the processing (S12) of editor terminates.In order to start the processing of PLC input/output list editors, designer's point " input/output list generation " (S50) hit in multiple call buttons of file.Specifically, file illustrated in fig. 7 is clicked on Multiple call buttons 64,66,68,70 in " input/output list generation " 68 (click on 2).Thus, auxiliary program enters next Individual process step, the selecting switch that input-output equipment is entered in fig. 13 is shown (S52).

In S52, the image of the selecting switch of display input-output device in the picture of display part 46 of servicing unit 40 Data.As the example of the view data of the selecting switch of display input-output device, selecting switch image 84 is shown in Figure 14. It is shown in the left side of selecting switch image 84 being selected in the selecting switch image 80 of PLC innings number illustrated in fig. 10 The part of PLC innings numbers.Here, the result of reflection PLC structural tables editor (S12), display " 01 " is used as the PLC offices being selected Number.The right side of selecting switch image 84 is the image for selecting input-output equipment.Here, the class of display input-output device It is not " BO ", " AO ", " BI ", " AI ", " AI-R ".As being illustrated in Figure 12, in PLC01, input-output equipment is only Having " BI64 ", this is a kind of, thus designer's selection " BI ", presses the selecting switch of " BI ".Thus, input-output equipment is carried out Select (S54).

At the end of the selection of input-output equipment, designer presses the picture (not shown) for being shown in display part 46 in Figure 14 The Next button in face angle portion.Thus, auxiliary program enters next process step, and in fig. 13, servicing unit 40 is carried out PLC input and output blank tables are shown (S56).

As shown in PLC01 PLC structural tables 34, " BI64 " has 3, is respectively arranged at 1~slot of slot 3.Therefore, aobvious Show the view data of 3 PLC input and output blank tables 35 of the overlapping display in portion 46.Figure 15 is the 1st PLC input and output blank table 35 View data, be related to " BI64 " for being configured at slot 1.Below, the view data of PLC input and output blank table 35 is referred to as PLC input and output blank table 35.PLC input and output blank table 35 and management project table 32, PLC structural tables 34 are same, be also by The worksheet of multiple cell arrangements as defined in multiple rows and multiple row.The aobvious of line number and row number is eliminated in fig .15 Show.

PLC input and output blank table 35 has the title bar for charging to the item for determining the PLC and shows that the input and output are set The input/output information column of standby input/output information.Title bar reflects the record of the PLC structural table 34 relevant with PLC01, case Part name, subsystem, system, office number, board name directly turn to remember the record of PLC structural tables 34 automatically.

Input/output information column is to show the input-output equipment i.e. terminal of " BI64 " and relevant with the PLC i.e. PLC01 Controlling element or monitoring key element between relation relation table.Controlling element and monitoring key element are used in management project table 32 Management project title is represented, thus input/output information column shows the input-output equipment i.e. terminal and management project of " BI64 " Relation between title.Plate business and Program Generating business are according to such input relevant with each input-output equipment in each PLC The information on output information column, carries out the making of various plates and the generation of PLC program.

Positioned at the marge on input/output information column " model name ", " slot number " and " beginning XY " charge to and the input Output equipment is " BI64 " relevant basic item.On its content, when selecting the input-output equipment, in PLC structural tables Directly turn note record corresponding with the input-output equipment in 34 PLC structures column.In above-mentioned example, " model name " from Dynamic to turn note " BI64 ", " slot number " turns note " 1 " automatically, and " beginning XY " turns note " 0100 " automatically.

" the pin number " on input/output information column is the terminal number of the input-output equipment." CH " is that the input and output are set The channel number of standby i.e. " BI64 "." address " is " CPU " the i.e. address of " QCPU15k " in the PLC." title " is management project table " management project title " in 32.The standard type of input-output equipment is 16 passages, and terminal is 20 terminals, thus in standard " pin number " is recorded in PLC input and output blank table 35 in advance to 20, " CH " is recorded to 16." BI64 " is 64 passages, thus Passage " 1 "~passage " 64 " is recorded to " CH " in advance in PLC input and output blank table 35, " pin number " recorded in advance The terminal number of " 1 "~" 80 ".Also, " beginning XY " is " 0100 ", in advance to " address " record " X100 "~" X13F " for reflection. Show that part thereof of " pin number " arrives " 1919 " in Figure 16, " CH " is arrived " 34 ", address to " X121 ".

Because " pin number " " 1B04 "~" 1B01 " etc. is vacant, thus designer can use these pins to install The common terminal of power supply.For example, the common terminal of PLC01 power supply can be set as COM1, vacant pin number is set COM1.At the end of content check, necessary additional setting in PLC input and output blank table 35 etc., designer is pressed in Figure 16 The Next button in the picture corner (not shown) for being shown in display part 46.Thus, picture of the servicing unit 40 in display part 46 The view data of label screen illustrated in fig. 7 is shown in face.

Designer clicks on " input/output signal distribution " (S58) of the call buttons of file.Specifically, Fig. 7 is clicked on " input/output signal distribution " 70 (clicking on 3) in multiple call buttons 64,66,68,70 of the file of middle explanation.

Thus, auxiliary program enters next process step, and in fig. 13, servicing unit 40 is managed project table data The retrieval (S60) in storehouse 50, servicing unit 40 for the PLC the input-output equipment, to PLC input and output blank table 35 successively Distribute input/output signal (S62).The process step is performed according to the following steps.

First, management project table 32 is read from management project table database 50.Then, it is used as the 1st inspection using PLC innings numbers=01 Rope keyword, by the classification of the corresponding input/output signals of model name i.e. " BI64 " of the input-output equipment with selecting i.e. " BI " is extracted " management project title " successively as the 2nd search key according to the order of line number from small to large.

Then, for multiple " the management project titles " that extract, " duplication " line number minimum " management project title ", and " stickup " is in " title " of " CH "=1 of PLC input and output blank table 35.In Fig. 6 management project table 32, at PLC innings Number=01, in management project title corresponding with " BI ", the management project title of minimum line number=7 is " low temperature PACACP State ".Therefore, it is automatic " duplication " portion of management project table 32 from worksheet using " replicating ＆ to paste " function of making list procedure Point, and " stickup " is in " title " of " CH "=1 of PLC input and output blank table 35 in other worksheet automatically.Then, for Multiple " the management project titles " extracted from management project table 32, according to the order of line number from small to large automatic " duplication " " pipe Manage project name ", and according to the order of " CH " number from small to large automatic " stickup " PLC input and output blank table 35 " title " In column.In addition, for " BI ", in management project table 32, " the management project of circles mark will be attached with to " metering " of " BI " Title ", the automatic note that turns is in the adjacent " class signal in corresponding " title " column of PLC input and output blank table 35 together with " metering " Not " in column.So, servicing unit 40 carries out PLC to PLC input and output blank table 35 successively automatic distribution input/output signal Input/output list editor simultaneously shows its result (S64).

Figure 16 shows the PLC input and output after editor for first PLC innings numbers=01, input-output equipment=" BI64 " Table 36a.In Fig. 6 management project table 32, relevant " management project title " shows 7 row~25 with PLC innings numbers=01, " BI " OK, for the row of wherein 16 rows~22, " metering " to " BI " is attached with circles mark.Correspondingly, by Fig. 6 management project table " the management project title " of the row of 32 7 rows~25 directly turns to remember " CH "=1~19 in Figure 16 PLC input/output lists 36a " title " on.Also, in " signal classification " column of " CH "=10~16 in Figure 16 PLC input/output lists 36a, reflection Circles mark in " metering " of the row of 16 rows of Fig. 6 management project table 32~22, is recited as " measuring ".So, Fig. 7 is merely clicked on " input/output signal distribution " 70, the content of management project table 32 be the automatic note that turns in PLC input/output lists 36a, go forward side by side Row PLC input/output lists 36a editor.

So far, the editor of the PLC structural table 34 relevant with PLC01, configuration PLC01 slot=1 " BI64 " PLC Input/output list 36a editor terminates.Figure 17 is the flow chart for showing the later step that servicing unit 40 is carried out.In S66, Judge " whether having been completed to fully entering output equipment ".In above-mentioned example, on PLC01, do not complete with being respectively configured In the relevant PLC input/output lists 36 of slot=2,3 " BI64 ".Therefore, S66 judgement is negative, therefore " returns to B " (S68)。

" initial step that B " refers to return to PLC input and output editor (S14) is returned, Figure 13 S50 is thereby returned to. Here, servicing unit 40 in the selection (S52) of input-output equipment option and installment slot=2 " BI64 ", and carry out with Step afterwards, thus, PLC input/output list 36 of editor's configuration at " BI64 " of slot=2.Therefore, it is being again introduced into S66 When, because the relevant PLC input/output lists 36 of " BI64 " with configuration in slot=3 are not yet completed, thus S66 judgement is no It is fixed, into S68, again return to S50.Here, option and installment is in slot=3 in the selection (S52) of input-output equipment " BI64 ", and later step is carried out, thus, PLC input/output list 36 of editor's configuration at " BI64 " of slot=3.Therefore, When being again introduced into S66, for the fully enter output equipment relevant with PLC01, the editor of PLC input/output lists 36 terminates, Thus S66 judgement is affirmative, can enter S70.

In S70, whether servicing unit 40 judges " having been completed to whole PLC innings numbers ".It is only right in above-mentioned example PLC01 complete PLC structural tables 34 editor and PLC input/output lists 36 editor, still, for other PLC02~ The editor of PLC05, PLC structural table 34 and the editor of PLC input/output lists 36 do not complete.Therefore, S70 judgement is negative, " return to A " (S72).

" initial step that A " refers to return to PLC structural tables editor (S12) is returned, Fig. 8 S30 is thereby returned to.Cause This, above-mentioned steps are repeated to PLC02~PLC05 respectively.The explanation of its details is to repeat, thus is omitted, and is used Figure 18~Figure 21 illustrates " AO " and " AI-R " of input-output equipment.
