Optimum instruction generating unit 69 has progress (Japanese Patent Laid-Open 2009-54056 such as above-mentioned patent document 1,2 Publication, Japanese Patent Laid-Open 2009-54055 publications) disclosed in existing processing function part, therefore do not carry out especially here Explanation.

But, it is by the access target (distribution for each project for being stored in common storage 55 if simply illustrating Storage area) access target is generated in the way of merging access.For example, having project A, B, C, have respectively No. D101, No. D105, In the case of No. D108 distribution storage area, stored the region merging technique untill No. D101~No. D108 as an access target In optimum instruction list 54.

Certainly, due in the processing, also obtaining unwanted data, therefore only by data (No. D101, the D105 of needs Number, each data of No. D108) be stored in the corresponding region of common storage 55.Also, give up should not data.

Generally, the processing via communication line 6 with being connected the communication of equipment 4 more expends the time, thus, even if the number obtained According to amount slightly increase and additional Screening Treatment, processing time can also shorten.

But, it is above-mentioned that address is merged into one like that, number of communications is reduced, is not that one will surely shorten processing time, Therefore the generation of optimum instruction list 54 is not essential.However, in the case of not generating optimum instruction list 54, this method In, also there is the external storage access for being associated hereafter above-mentioned logical process to include to project and show associated circulation The situation that external storage is accessed.

In addition, such as above-mentioned above, each connection equipment 4 of correspondence sets communication processing section 63 and optimum instruction list 54 (to enter one Step has hereafter above-mentioned instruction list 53 etc.).Thus, connection equipment 4 have it is multiple in the case of, communication processing section 63 and optimal Instruction list 54 etc. is also provided with multiple.However, in this explanation, it is not right for communication processing section 63 and optimum instruction list 54 etc. Each connection equipment 4 (4-1,4-2) illustrates, but uniformly illustrates.

In addition, optimum instruction generating unit 69 is entered substantially when for example along with screens switch renewal item list 51 One step with this along with update common storage 55 when, generate corresponding to the storage content of the new common storage 55 most Excellent instruction list 54.In other words, substantially this moment beyond the content of optimum instruction list 54 do not change.But, we In method, have and judge the situation that processing unit 70 makes the content of optimum instruction list 54 change using classification.For example have on hereafter The access target for the grade of logical process portion 64 stated adds the situation into optimum instruction list 54.In addition, at this moment, it is preferable that utilize Optimum instruction generating unit 69 carries out the optimization processing (link of address above mentioned for also including access target of the grade of logical process portion 64 Deng；Address is merged into one etc.), optimum instruction list 54 is generated again.Detailed following article is above-mentioned.

The storage data (" acquisition data ") of project processing unit 62 based on above-mentioned common storage 55 etc., hold to each project The processing being associated the renewal (being switched such as opening image or closing with image) of the row display content.That is, project is handled Portion 62 is such as based on the nearest acquisition data from above-mentioned distribution storage area, it is determined that or the above-mentioned display operation screen of renewal Display content.

The processing of above-mentioned project processing unit 62 is also periodically carried out, and the planning management is carried out by project processing plan portion 65.That is, Project processing plan portion 65 is carried out the planning management of the display renewal processing of projects etc. by project processing unit 62.That is, at project Reason planning department 65 for example regularly recalls project processing unit 62, performs for example that hereafter above-mentioned Fig. 8 processing (in other words, is circulated Perform Fig. 8 processing).

More than, mainly to the decision or renewal processing (refresh process) of the display content for showing projects on operation screen (still, classification judge processing unit 70 except) is illustrated in associated processing function portion or data etc..

On the other hand, such as above-mentioned above, CPU11 also carries out above-mentioned logical process.The logical process performs associated place Logical process portion 64, logical process planning department 67, logical order generating unit 68, logic that function part, data etc. are diagrams is managed to refer to Make list 52 and instruction list 53 (53-1,53-2) etc..

Above-mentioned logical process perform associated processing function portion, data etc. substantially with beyond logical process portion 64 with Past is almost identical, therefore simply illustrates below.

Logical order generating unit 68, will be based on arbitrary access target (any connection equipment 4 for arbitrary logical program Any external storage device arbitrary address) data processing (such as branch process；If~then~else etc.) it is related The information of connection is stored to logical order list 52.Show that concrete example is illustrated after for logical order list 52.

Logical process portion 64 carries out logical order list 52 based on the planning management using logical process planning department 67 Corresponding data acquisition process etc..For example, the above-mentioned access target for being stored in logical order list 52 is stored in into shared storage Device 55, and the instruction generated based on the access target is stored in instruction list (FIFO) 53.

In addition, " access process " in following explanation is substantially represented " processing for accessing external storage ".Likewise, " access target " is substantially represented " arbitrary address of any external storage device of any connection equipment 4 ".

Here, the communication processing section 63 of this example not only performs the access process based on above-mentioned optimum instruction list 54, also holds Access process of the row based on instruction list 53.That is, any one instruction (such as hereafter above-mentioned instruction is stored in instruction list 53 130 etc.) in the case of, the instruction is extracted, is conducted interviews processing based on the instruction.Also, by access process result (from access " the acquisition data " of target) store to the corresponding region of common storage 55.

Logical process portion 64, which is waited, is stored above-mentioned " acquisition data " to above-mentioned common storage 55 by communication processing section 62 Corresponding region in, after storage, above-mentioned processing (such as branch process) is performed based on the acquisition data.Particularly branch process In the case of, which in then and else is performed if not knowing if mustn't go to above-mentioned acquisition data, therefore is waited.Cause This, there is the situation that stand-by time is elongated.If in addition, frequently carrying out irregular (sudden) visit along with logical process like this Processing is asked, then the access process that above-mentioned refresh process is associated is impacted, has display content to update time-consuming situation.

Thus, in this method, in the access target with irregular (sudden) access process of logical process, there is frequency The access target of processing that conducts interviews numerously in the case of, the access target is set to include to optimum instruction list 54.Accordingly, for The access target, occurs, progress above-mentioned circulation visit unrelated with irregular (sudden) access process of logical process with whetheing there is Ask, obtain data storage in the corresponding region of common storage 55.

And in the case of access target irregularly the processing generation of (sudden) access, logical process portion 64 is obtained altogether With the storage data of the corresponding region of holder 55.Thus above-mentioned stand-by time, and the also above-mentioned brush of without prejudice to are hardly consumed The associated access process of new processing.Thus, the renewal processing of project display content will not be slack-off.

In addition, also including hereafter above-mentioned burst holder visiting portion 64a (not shown) processing in logical process portion 64 Function.Thus, logical process portion 64 not only carries out hereafter above-mentioned Figure 10, Figure 11 processing, also carry out hereafter above-mentioned Figure 12, Figure 13 processing.Detailed following article is above-mentioned.

Below, above-mentioned various processing function portions and various data are further described.

First, to communication processing section 63, and its detailed processing example is illustrated.

Fig. 6, Fig. 7 are that each communication processing section 63 (63-1,63-2) for example regularly (cyclically) performs external storage respectively The flow chart (1/2) of device access process, (2/2).In addition, not making especially differentiation below, labeled as " Fig. 6 etc. ".

In processing example above-mentioned Fig. 6 etc., the communication process of the associated circulation of above-mentioned refresh process is essentially performed, but Associated irregular (sudden) communication process of above-mentioned logical process is carries out the communication process in the case of necessary.In addition, Irregularly (sudden) communication process is that necessary situation refers to, for example, (instruction from somewhere is represented into the finger of access target Order；Such as hereafter above-mentioned instruction 130) when be stored in above-mentioned instruction list 53.

In addition, the processing of the communication processing section 63 shown in Fig. 6 etc. can be prior art in itself.In addition, the processing is related , should in the various data of connection (optimum instruction list 54, common storage 55, instruction 130 hereafter exemplified by above-mentioned Figure 19) Data structure can also be prior art in itself.But, also there is the situation of the content of data unlike the prior art.That is, most Excellent instruction list 54 has the not only associated access target of the communication process comprising above-mentioned circulation, also comprising above-mentioned bursty communication The situation of the associated access target of processing.Detailed following article is above-mentioned.

For the communication process of above-mentioned circulation, arbitrary holder access instruction is obtained from optimum instruction list 54 first (step S11).This is for example correspondingly to refer to the execution index (not shown) in optimum instruction list 54 to extract as keyword Order.

Here, Figure 19 represents the data structure example of above-mentioned instruction.In addition, optimum instruction list 54 and instruction list 53 are for example It is by the content of the list of instruction 130 as shown in Figure 19.

Instruction 130 exemplified by Figure 19 is by instruction type 131, storage module number 132, (the N number of storage of each storage module 133 Storing module 133) etc. constitute.

Instruction type 131 is such as being " module reading ", " multimode reading " as one.Because these are also existing skill Art, therefore be not described in detail especially, but simple illustration following article is above-mentioned.

Module is read；The instruction specified to arbitrary beginning address and data amount check.Address acquisition data from the outset The data in the region of individual quantity.Storage module number 132 is fixed as ' 1 '.

Multimode is read；It is the instruction that the module expanded is read, multiple access targets can be specified.That is, storage module Number 132 is more than ' 2 '.

Storage module number 132 is the number of storage module 133.

In each such as example illustrated of storage module 133, by port 141, equipment 142, address 143 and data amount check Each data items such as 144 are constituted.Port 141, equipment 142 and address 143 represent access target (such as above-mentioned distribution storage area Beginning address).That is, port 141 is identiflication number of the corresponding port of connection equipment 4 of access target etc..Equipment 142 is to visit Ask identification information of storage facilities of access target in the connection equipment 4 of target etc..Address 143 is access in the storage facilities Beginning address of the storage area of target etc..

Also, the storage area of the region representation access target of the amount of the data amount check 144 from the beginning address, the storage The storage data for depositing region are read.

That is, in Fig. 7 etc. processing, by the way that the instruction obtained in above-mentioned steps S11 processing 130 is sent to access mesh Target connection equipment 4 (step S12), the storage of the above-mentioned access target represented in the connection side of equipment 4 from above-mentioned each storage module 133 Region is deposited, storage data is read and replys.If receiving the reply (step S13), " acquisition data " that the reply is included (from The data that the storage area of above-mentioned access target is read) store into the corresponding region of common storage 55.The processing in itself may be used With as in the past, but in the case of this example, in above-mentioned " acquisition data ", have and not only include following of being used for that above-mentioned project to show The associated data of the communication process of ring, also comprising the associated data of above-mentioned bursty communication processing.

Finally, the execution index (not shown) in above-mentioned optimum instruction list 54 is for example made to advance to next instruction (step Rapid S15).That is, the instruction 130 of next process object is specified.

Then, from (the step of instruction 130 for the 130 groups of acquisition beginnings of more than one instruction for being stored in instruction list 53 S16).But, in the case of 130 no ones are instructed in instruction list 53 (step S17 is no), present treatment terminates.

Obtain in the case of any one instruction 130 from instruction list 53 (step S17 is yes), to the processing pair The instruction 130 of elephant also carries out step S12, S13, S14's associated with the instruction 130 obtained from above-mentioned optimum instruction list 54 The almost identical processing (step S18, S19, S20) of processing.

That is, it will be sent in the above-mentioned steps S16 instructions 130 obtained to the connection equipment 4 (step S18) of access target, by This reads storage data from the storage area of access target in the connection side of equipment 4 and replied.If receiving the reply (step S19), " the acquisition data " that then reply is included are stored into the corresponding region of common storage 55 (step S20).

Also, it is last, the request source (such as logical process portion 64) of the instruction 130 of above-mentioned process object is notified to complete (step S21).Logical process portion 64 of the completion notice etc. is received, is stored from the reading above-mentioned steps of common storage 55 S20 Data etc..

Here, Figure 16 (a) represents the data structure example of common storage 55.

In the example shown in Figure 16 (a), the storage data of common storage 55 are by port 81, data name 82, address 83rd, each data item such as data 84, cyclic access counter 85, Burst frequency access counter 86 and upgrading judge mark 87 Mesh is constituted.

Among these, port 81, device name 82, address 83 and data 84 can be identical with conventional, simply enter below Row explanation.

Port 71 is identification information of above-mentioned COM1 etc., and substantially the connection equipment 4 to communication counterpart is identified Information.Equipment 72 is the identification information of the storage facilities (external storage) in the connection equipment 4 of communication counterpart.Address 73 is Equipment 72 is represented in the address of storage area specified in external storage, the data storage from storage area acquisition is in data In 74.In addition, port 71, device name 72 and address 73 are also seen as above-mentioned " the distribution holder equivalent to projects Location ".

Beyond above-mentioned conventional data items, above-mentioned cyclic access counter 85, Burst frequency are also set up in this example and is accessed Counter 86 and upgrading judge mark 87.These are illustrated after, makees brief description here.

First, the associated access target of above-mentioned refresh process is stored and from the access target in common storage 55 Data etc. are obtained, the associated access target of above-mentioned burst access processing and the acquisition data from the access target are also stored Deng.Also, for the record that above-mentioned refresh process is associated, value (+1 as defined in storage is forced in cyclic access counter 85 Deng), and without using Burst frequency access counter 86 and upgrading judge mark 87.On the other hand, for above-mentioned burst access The associated record of processing, forces storage ' 0 ' etc., and use Burst frequency access counter in cyclic access counter 85 86 and upgrading judge mark 87.

Here, if the application method to these counters 86 and mark 87 is simply illustrated, it assumes that performing every time During arbitrary above-mentioned sudden access process, the Burst frequency access counter 86 of corresponding record is set to be counted upwards.And And, in the case that the value of counter 86 exceedes defined threshold value, upgrading judge mark 87 is opened for mark.Also, make above-mentioned The process object of communication cycle processing is not only comprising the record that cyclic access counter 85 is setting (+1 etc.), also comprising upgrading The record that judge mark 87 is opened for mark.

In addition, above-mentioned Burst frequency access counter 86 is periodically reset.Thus, in the value of specified time limit inside counting device 86 Access, that is, in the case of frequently executing access, make in above-mentioned burst access processing, the also visit comprising circulation more than above-mentioned threshold value Ask processing.Also, samely, in this method, the access process to circulation is optimized.Thus, burst is contained to visit Ask that the overall access efficiency of the external storage access process of processing is improved.It is however not limited to the example.Also can be without excellent Change, and above-mentioned burst access processing is merely included in cyclic access processing.

Then, reference picture 8, the processing to project processing unit 62 is illustrated.

Fig. 8 is the process chart of project processing unit 62.

Project processing unit 62 is periodically recalled using project processing plan portion 65 as described above, performs Fig. 8 processing.

In the processing example of diagram, first, the processing of whole records of bulleted list 51 is completed into mark 119 and initialized (mark is closed) (step S31).

Here, Figure 17 (b) represents the data structure diagram of bulleted list 51.

The bulleted list 51 of example illustrated is by item types 111, coordinate 112, size 113, port 114, device name 115th, address 116, the data 117 of each item types and processing complete each data items composition such as mark 118.Project is arranged Each record of table 51 is corresponding with projects of operating display frame.In addition, example illustrated is not limited to, it is further or every Purpose identiflication number etc..

Stored in item types 111 and represent that the project kind of the project kind (switch, lamp, numerical value are shown) recognizes letter Breath.

In addition, port 114, device name 115 and address 116 are the associated storage distribution information of projects, equivalent to Above-mentioned distribution holder address.That is, in the external storage that the device name 115 in the corresponding connection equipment 4 in port 114 is represented The storage area that address 116 is represented is the region (above-mentioned distribution storage area) that the project is distributed.The distribution storage area Storage data represent the current state of the associated control of the project or supervision object.If such as item types 111 are lamp, Flag data lighted or extinguished of indication lamp etc. is above-mentioned storage data.

The data 117 of every kind of item types are image (such as the lamp opening image and lamp closing image of such as project Deng).Coordinate 62 and size 63 represent display location and the size of the item image.

It is back to Fig. 8 explanation.

Then above-mentioned steps S31 processing, by the arbitrary untreated project from bulleted list 51, (processing is completed Mark 119 records associated project for what is closed) as process object (step S32).Also, obtained in common storage 55 The grade of data 84 of the corresponding record of above-mentioned process object project is used as holder information 71 (step S33).

In addition, for example, the port 114 of the port 81, device name 82 and address 84 and above-mentioned process object, setting Standby title 115 and the identical of address 116 are recorded, and are above-mentioned corresponding records.

Here, one of the above-mentioned holder information 71 of Figure 17 (a) expressions.

The holder information 71 of example illustrated is by data 101, cyclic access counter 102, Burst frequency access count Device 103 and upgrading judge mark 104 etc. are constituted.This is for example by the data 84 of above-mentioned corresponding record, cyclic access counter 85th, the content that Burst frequency access counter 86 and upgrading judge mark 87 are replicated.

It is however not limited to which above-mentioned example, such as holder information 71 also can be only above-mentioned data 101.

Also, using the holder information 71 of above-mentioned acquisition, carry out the associated display (step of above-mentioned process object project S34).Certainly, at this moment, data (coordinate 112, size 113 or the item of above-mentioned process object project in bulleted list 51 are also utilized Mesh image etc.) carry out display processing.

Finally, it is used as in bulleted list 51 the processing completion mark 118 of the record of above-mentioned process object project to have handled Into (mark is opened) (step S35).Also, in the case of the remaining untreated record of bulleted list 51 (step S36 is yes), Return to step S32.Above-mentioned steps S32~S35 processing (step is performed to whole records (whole projects) of bulleted list 51 S36 is no), then present treatment terminates.

Then, common storage generation processing unit 66 is illustrated.

Fig. 9 is the process chart that common storage generates processing unit 66.

Common storage generates processing unit 66 for example when being transferred out every time from project generating unit 61, performs Fig. 9 processing. Project generating unit 61 for example every time based on picture data 22 when bulleted list 51 generates new list (new record), is recalled altogether Processing unit 66 is generated with holder.At this moment, project generating unit 61 will represent that the information of the new list (new record) of above-mentioned generation (refers to Pin) it is sent to common storage generation processing unit 66.

Thus, common storage generates new list (the new note with reference to above-mentioned generation in bulleted list 51 of processing unit 66 Record), obtain (step S51) such as the port 114, device name 115, addresses 116.

Also, based on the acquisition data, (step is judged to whether the record completes to log in common storage 55 Rapid S52).For example, in common storage 55, exist the port 81, device name 82, the port 114 of address 83 and above-mentioned acquisition, In the case of device name 115, the identical of address 116 record, it is judged as logging in completion (step S52 is yes).In this case, not Step S53 processing is carried out, step S54 processing is transferred to.

On the other hand, do not complete in the case of logging in (step S52 is no), the above-mentioned data supplementing is logged on into shared storage Storage 55 (step S53).That is, new record is added in common storage 55, is stored up in the port 81, device name 82, address 83 Deposit each data of the port 114 obtained in above-mentioned steps S51, device name 115, address 116.Also, shifted to step S54.

The record completed in step S54, common storage 55 to above-mentioned login or the record added in above-mentioned steps S53 (it is not to update that can also regard as to middle renewal (+1 etc.) above-mentioned cyclic access counter 85, but regards pressure as so that it becomes setting (being here ' 1 ')).Thus, such as hereafter above-mentioned step S72 is judged as NO.Also, terminate present treatment.

Then, the processing to logical process portion 64 is illustrated.

Figure 10, Figure 11 are the process chart (1/2) in logical process portion 64, (2/2).In addition, do not make especially differentiation below, Labeled as " Figure 10 etc. ".

In addition, such as above-mentioned above here, logical process portion 64 also carries out hereafter above-mentioned Figure 12, Figure 13 processing.

In processing example shown in Figure 10 etc., first, the processing of whole records of logical order list 52 is completed into mark 137 Initialized (mark is closed) (step S41).

Here, logical order 52 is illustrated.

Figure 18 is the concrete example of logical order list 52.

The logical order list 52 of illustrated example has execution condition 121, port 122, device name 123, address 124, life Make line number 125, respectively order 126, processing complete mark 127, the data items such as sub-value 128 on instruction memory.

Port 122, project name 123 and address 124 represent access target.That is, the corresponding connection equipment 4 in port 122 The storage area that address 124 is represented in the external storage device that interior device name 123 is represented is access target.This is accompanied by The access target that the arbitrary logical process accessed to external storage is associated (also has the feelings of referred to as instruction memory below Condition).Also, the associated order of the arbitrary logical process is stored in each order 126 line by line.Also, of the order 126 Number (line number) is stored in order line number 125.

Also, store the condition for performing above-mentioned each order 126 in execution condition 121.This be substantially based on it is above-mentioned The condition of the storage data of access target.For example, in the case that the storage data of above-mentioned access target are the mark of 1, for example Switching from from mark off-mode to mark open mode becomes execution condition 121.In the example, for example logical process portion 63 exists The marker for judgment of above-mentioned access target is in the case of switching from closing to opening, to perform above-mentioned each order 126.

In the judgement that above-mentioned execution condition 121 is associated, for example with sub-value on instruction memory 128.That is, following article Above-mentioned, logical process portion 64 is stored up when newly obtaining the storage data of above-mentioned access target every time based on the acquisition data and instruction Sub-value 128 carries out above-mentioned judgement on storage.It is that mark is opened and sub-value 128 is mark on instruction memory for example to obtain data In the case of closing, it is judged as switching to the state of opening from closing.In addition, it is unrelated with judged result, newly obtain every time above-mentioned During the storage data of access target, stored the acquisition data as sub-value 128 on new instruction memory.

In addition, respectively record (is particularly the execution condition 121, port 122, device name in above-mentioned logical order list 52 123rd, address 124, order line number 125, each order 126 etc.) generated by logical order generating unit 68.This is for example based on arbitrary Logical program generation.The generation processing is existing processing in itself, is not especially illustrated or is illustrated here.Also, logic Processing unit 64 performs Figure 10 etc. processing using the grade of logical order list 52 of above-mentioned generation.It is back to Figure 10 etc. explanation.

Above-mentioned steps S41 processing is performed, then using each record of above-mentioned logical order list 52 as dealing with objects successively Repeat the processing between the step S42- steps S46 of diagram.

That is, with reference to the untreated record (logical order) (step S42) from above-mentioned logical order list 52, for example, know The access target (instruction memory), the data i.e. data for obtaining or storing from the access target are not obtained from common storage 55 84 (step S43).That is, the port 81 in common storage 55, device name 82, address 83 and above-mentioned process object are for example obtained Port 122, device name 123, the identical of address 124 record in data 84.

Also, sub-value 128 etc., the data of decision instruction holder in data 84 and above-mentioned instruction memory based on acquisition Whether change (step S44).Such as above-mentioned one like that from mark close change turn to mark open (or vice versa, from mark beat Open change turn to mark close) etc. in the case of, whether the data of decision instruction holder change (step S44 is yes).The feelings Under condition, further, based on above-mentioned execution condition 121 etc., judge whether to perform triggering (step S47).

In above-mentioned one, close change from mark and turn in the case that mark opens, being judged as performing triggering, (step S47 is It is), step S48 processing is performed, step S49 processing is performed afterwards.On the other hand, in above-mentioned one, open and become from mark In the case of turning to mark closing, it is judged as being not carried out triggering (step S47 is no), step S48 processing is not performed, directly Perform step S49 processing.

Step S48 processing be perform successively in the logical order of above-mentioned process object above-mentioned each order 126 processing (according to Secondary execution the first row~Nth row).Also, with the execution successively of each order 126, accessed in each arbitrary external storage During generation, such as, using the burst holder visiting portion 64a (not shown) with logical process portion 64, perform hereafter above-mentioned figure The processing of 12 grades.To each logical order, step S48 processing, therefore Figure 12 etc. processing are only carried out when step S47 is to be Middle external storage, which is accessed, becomes irregular (sudden) external storage access process.In addition, representing the information of access target For example comprising extremely order 126.

In addition, step S49 processing is by sub-value on above-mentioned instruction memory in the logical order of above-mentioned process object 128 processing being updated using the above-mentioned steps S43 data 84 obtained.

Also, it is last above-mentioned processing is completed the processing completion (mark of mark 127 in the logical order of above-mentioned process object Open) (step S45).

Also, (step S46 is in the case of the remaining untreated record (logical order) of above-mentioned logical order list 52 It is), return to step S42.If the state (step S46 is no) without untreated record (logical order), terminates present treatment.

The external storage access process that Figure 12, Figure 13 are accompanied by logical process is (i.e. above-mentioned irregular (sudden ) access process) process chart (1/2) in logical process portion 64 when occurring, (2/2).In addition, not making special area below Point, labeled as " Figure 12 etc. ".

In addition, such as above-mentioned above, Figure 12 etc. processing can also be regarded as with the (not shown) sudden of logical process portion 64 The content that holder visiting portion 64a is performed.But, in the present invention, do not carried especially for sudden holder visiting portion 64a And, the situation for being denoted as the content of the execution of logical process portion 64 is more.

In processing above-mentioned Figure 12 etc., logical process portion 64 recognizes irregular (sudden) access process of above-mentioned generation Access target, the data of the access target be stored in as above-mentioned data 84 in shared data 55 in the case of (in other words, comprising In the case of the access process of circulation), obtain the data 84.This is for example, first, it is determined that whether above-mentioned access target logs in In common storage 55 (step S61).This is for example, the port 81, device name 82, address 83 and above-mentioned access target (should Port, device name, address) identical record be present in common storage 55 in the case of, be judged as having logged in (step S61 is yes).

Also, if above-mentioned access target is not logged in holder 55 (step S61 is no), then by the access target Xindeng Record is in common storage 55 (step S62).This is for example to add new record in common storage 55, (should by above-mentioned access target Port, device name, address) store in the port 81 of the new record, device name 82, address 83.In addition, the new record is followed Ring access counter 85, Burst frequency access counter 86, upgrading judge mark 87 are set as predetermined original state. That is, such as cyclic access counter 85 and Burst frequency access counter 85 are set to initial value ' 0 '.Upgrading judge mark 87 is set Closed for mark.

Then, from common storage 55 obtain the record (the associated login of above-mentioned access target complete record or on State new record) data 84, cyclic access counter 85, Burst frequency access counter 86, upgrading judge mark 87 as storage Storage information 71.These sentence as above-mentioned data 101, cyclic access counter 102, Burst frequency access counter 102, upgrading Disconnected mark 104 and obtain (step S63).

Also, based on above-mentioned holder information 71, determine whether cyclic access object (step S64).This is in step Cyclic access counter 102 is that more than ' 1 ' situation or upgrading judge mark 104 are mark in the holder information 71 that S63 is obtained In the case that note is opened, it is judged as cyclic access object (step S64 is yes).

In addition, in the case that above-mentioned this is recorded as new record, certainly, step S64 is judged as NO.

Even in addition, the content crossed for the access target that logical process is associated by hereafter above-mentioned " upgrading ", step Rapid S64 is judged as YES.That is, included for such a access target to above-mentioned cyclic access object.Thus, should be with above-mentioned item Mesh shows that associated cyclic access processing is together accessed.Detailed following article is above-mentioned.

In the case of having cyclic access object, the data 84 (data 101 in holder information 71) obtained in step S63 It is the data that should be obtained in this access process.That is, handled and obtained from the storage area of above-mentioned access target using cyclic access Newest (recently) data taken should be stored as data 84.Thus, in this case, being performed using the data 84 obtained Defined logical process.Also, the login that above-mentioned access target in common storage 55 is associated is completed to the burst frequency of record Rate access counter 86 is updated (+1 is incremented by) (step S68), terminates present treatment.

On the other hand, it is not in the case of cyclic access object (step S64 is no), to perform existing access process.That is, Generation includes the above-mentioned instruction 130 of above-mentioned access target (port, device name, address), is added and is stored in instruction list 53 (step S65).Also, the instruction 130 of 63 pairs of communication processing section performs above-mentioned Fig. 6 etc. processing, wait above-mentioned steps S21's Access the progress that completion event is notified.Also, once receive and access completion event and notify, at this moment should the above-mentioned record number According to newest (nearest) data that above-mentioned access target is stored in 84.Thus, the data 84 (step S67) are obtained, using obtaining The data 84 taken perform above-mentioned defined logical process.Also, to the note that above-mentioned access target in common storage 55 is associated The Burst frequency access counter 86 of record is updated (+1 is incremented by) (step S68), terminates present treatment.

In the associated existing access process of above-mentioned sudden access, the stand-by period for having above-mentioned steps S66 becomes non- Situation about often growing.This is for example, forcing the situation of the 130 wait orders of other instructions stored in instruction list 53.With This is relative, in the case of being judged as YES of above-mentioned steps S64, the data 84 from the acquisition of common storage 55 can be utilized to be immediately performed Logical process.That is, processing time can be shortened.The mailing address that the instruction 130 of instruction list 53 is associated is stored in addition, can mitigate The processing load in reason portion 63.Also, the access process for hindering above-mentioned refresh process associated is reduced using sudden access process.

Even in addition, the access target associated on logical process relation becomes also as described below by " upgrading " The object of the optimization of above-mentioned optimum instruction generating unit 69, therefore can efficiently obtain the data of access target.Detailed following article institute State.

Above-mentioned " upgrading " etc. judges that processing unit 66 is carried out by classification.

Figure 14, Figure 15 are process chart (1/2), (2/2) that classification judges processing unit 66.In addition, not making below especially Distinguish, labeled as " Figure 14 etc. ".

Classification judges that processing unit 66 is periodically executed the processing shown in Figure 14 etc..

First, each record of common storage 55 is repeated into step S71 as dealing with objects successively to process object ~S78 processing.

I.e., first, the data 84 for dealing with objects record, cyclic access counter 85, Burst frequency access counter are obtained 86th, upgrading judge mark 87 is used as holder information 71 (step S71).But, in the following description, without using holder information 71 above-mentioned ' 101 ', ' 102 ' etc. symbol, but directly use above-mentioned ' 84 ', ' 85 ' etc. symbol.

Using above-mentioned holder information 71, it is first determined whether being classification object (step S72).At above-mentioned logic What the sudden access of reason was associated is recorded as being classified object.Thus, the cyclic access counter 85 of above-mentioned process object record In the case of more than ' 1 ', process object record is the associated record of above-mentioned refresh process, therefore is judged as it not being classification pair As (step S72 is no).

On the other hand, in the case of the deficiency of cyclic access counter 85 ' 1 ' (being ' 0 ' in this example), process object record is sentenced Break to be classified object (step S72 is yes), next, it is determined that whether process object record is upgrading object (step S73).This is example Such as, in the case that the value of the Burst frequency access counter 86 of process object record is more than first threshold set in advance, sentence Break as upgrading object (step S73 is yes).Also, in this case (step S73 is yes), pass through the upgrading by record is dealt with objects The mark of judge mark 87 is opened, and is made its " upgrading " (step S74).Also, shifted to step S77.

In addition, " upgrading " here refers to, the sudden access process for making process object record associated is included in above-mentioned In the associated cyclic access processing of refresh process.

In addition, process object record is judged as it not being in the case of upgrading object (step S73 is no), to judge process object It is degradation object (step S75) when record.This is for example, dealing with objects the value of the Burst frequency access counter 86 of record not In the case of foot Second Threshold set in advance, it is judged as degradation object (step S75 is yes).Also, in this case (step S75 is yes), by the way that the upgrading judge mark 87 for dealing with objects record is marked into closing, make its " degradation " (step S76).Also, Shifted to step S77.

That is, in this example, the associated sudden access process of process object record becomes to be included in cyclic access processing State after, be not limited to maintain the state all the time, also have from cyclic access processing and remove the situation of (carry out " degradation ") Situation.In addition, therefore as described above, even in step S64 in the case of being, also execution step S68 processing is (to burst Frequency access counter 86 is updated the processing of (+1)).

In addition, above-mentioned first threshold and the value of Second Threshold can arbitrarily be set, it is preferable to set into satisfaction " first threshold The condition of≤Second Threshold ".

In addition, in the case that step S75 is judged as NO, being directly transferred to step S77 processing.In addition, classification judges mark In the case that note 87 is closed for mark, also forcibly step S75 can be judged as NO.

Figure 14 etc. processing is regularly performed (every specified time limit) as described above, at this moment, by aftermentioned step S77 Processing, make process object record Burst frequency access counter 86 be back to original state (' 0 ').Thus, Figure 14 etc. The value of Burst frequency access counter 86 during processing represents the number of times for producing sudden access within above-mentioned specified time limit (to every The number of processing for Figure 12 that individual access target is produced along with logical process).

Here, suppose that having arbitrary specified time limit A and the specified time limit B after it.And, it is assumed that due to specified time limit A In the associated sudden access of arbitrary access target occurrence frequency it is higher, therefore Figure 14 when specified time limit, A passed through Deng processing in perform step S74 upgrading processing.Accordingly, for the access target, the figure in specified time limit after which In the processing of 12 grades, step S64 is yes, but in this case also performs step S58 processing as described above.Here, suppose that by , can also be in rule in the case that the occurrence frequency of the associated sudden access of above-mentioned access target is relatively low in specified time limit B Step S76 degradation processing is performed in Figure 14 when B passes through between periodically etc. processing.

No matter also, above-mentioned step S72, S73, S75 judged result, the Burst frequency for recording process object Access counter 86 is original state (removing ' 0 ') (step S77).Also, there is remaining untreated note in common storage 55 (step S78 is yes), return to step S71 in the case of record.

Each record of common storage 55 is recorded as above-mentioned process object successively, above-mentioned processing is performed, to whole (step S78 is no) is transferred to step S79 after record processing is performed.

The processing of step S79, S80 is the common storage 55 after the processing based on above-mentioned steps S71~S78, then secondary Into optimum instruction list 54.

I.e., first, the common storage 55 after processing based on above-mentioned steps S71~S78, generates cyclic access holder List 72 (step S79).This is in each record of common storage 55, to extract all records for meeting rated condition, be based on The record generation cyclic access holder list 72 of the extraction.Condition as defined in above-mentioned is that cyclic access counter 85 is more than 1, Or upgrading judge mark 87 is opened and (meets a wherein side).

In addition, the processing of step S79, S80 is that each port (connection equipment 4) is performed into processing as dealing with objects successively. Thus, strictly speaking, further comprising port of the port 81 for process object in above-mentioned rated condition.

Here, Figure 16 (b) represents the concrete example of cyclic access holder list 72.

In example shown in Figure 16 (b), cyclic access holder list 72 is made up of device name 91, address 92.The example In son, the device name 82 of each record of said extracted, address 83 are stored in device name 91, address 92.

Also, send the cyclic access holder list 72 of generation to optimum instruction generating unit 69 etc., utilize optimal refer to Generating unit 69 is made to generate new optimum instruction list 54 (step S80).In addition, utilizing the optimum instruction of optimum instruction generating unit 69 The generation processing of list 54 is prior art disclosed in above-mentioned patent document 1,2 etc., therefore is not illustrated especially herein.

Finally, in the case of having untreated port (step S81 is yes), return to step S79, for next processing pair The port of elephant also carries out the processing of above-mentioned steps S79, S80.Also, if processing (step S81 is no) is performed to full record, tie Beam present treatment.
