Summary of the invention

Herein, the real-world operation situation of above-mentioned PLC system, because the user of PLC system is different and varied with system constructing person, for example, has the following situation that will illustrate.

Above-mentioned what is called " on-screen data " is preserved and carries out in programable display, and what still generate is servicing unit, so, in a lot of situations, also keep on-screen data in servicing unit side.In addition, on-screen data is wanted upgraded version sometimes, sometimes not only preserves latest edition in servicing unit side and also preserves legacy version.

The on-screen data being kept in programable display is latest edition (current version) substantially.Thus, the on-screen data being kept in programable display is considered as to master data, in the time generating upgrade version, the on-screen data of programable display side (master data) is uploaded in servicing unit, and the situation that this on-screen data (master data) is generated to upgrade version as basis is a lot.

In the case, if programable display breaks down, cannot read its on-screen data (master data).

Or, the operator that on-screen data is generated by the operator who generates or trust conventionally manages, but, if operator changes etc., management becomes loaded down with trivial details, the on-screen data being particularly kept in servicing unit is lost sometimes, also on-screen data likely occurs and only remain in the situation of programable display side.In this case, break down and cannot take out on-screen data in the situation that, on-screen data is lost at programable display.

In addition, the on-screen data (master data) of preserving in programable display, implement is tampered, the possibility that certain abnormal operation occurs is large, if in the situation of not finding to distort, to generate accordingly upgrade version etc., the impact of distorting will exist always.

On the other hand, the on-screen data that also has to be kept in servicing unit is the situation that basis generates upgrade version.But in the case, developer etc. likely can generate upgrade version taking the on-screen data of legacy version as basis mistakenly.In the case, while there is the processing having in current version but do not have in legacy version, in upgrade version, no longer include this processing, have problems.In addition, be kept at on-screen data in servicing unit also likely because above-mentioned operator's change etc. is former thereby lose.

Problem of the present invention is, a kind of Display Management System, its server unit, programable display etc. are provided, can adopt the mode of centralized management to save in each programable display each on-screen data that keeps, implements from damage, and can prevent/be suppressed at that the on-screen data that programable display side keeps is tampered and the abnormal operation that occurs, can improve thus reliability.

Display Management System of the present invention is the system that connects programable display and server unit via network, has following structure.

Described programable display has the first on-screen data storage unit of the on-screen data used of this programable display of storage.

Described server unit has the second on-screen data storage unit of the each programable display of storage on-screen data separately.

The wherein one or both of described programable display and server unit has on-screen data judging unit, is used for that judgement is stored in on-screen data in described the first on-screen data storage unit and whether be stored in on-screen data in described the second on-screen data storage unit consistent.

For example, described programable display also has: the described on-screen data of making according to described on-screen data judging unit consistent/inconsistent judged result, control the action control unit of the action of this programable display.For example, in the time that described programable display starts, by described on-screen data judging unit carry out described on-screen data consistent/inconsistent judgement, described operation control unit is in inconsistent situation in this judged result, does not allow the startup of this programable display.

Embodiment

Below, with reference to accompanying drawing, embodiments of the present invention are described.

Fig. 1 is the structural drawing of this routine PLC system (Display Management System).

Illustrated Display Management System has: programable display 10, server unit 20, plotting unit (servicing unit) 30.In addition can be also that the function of plotting unit 30 is contained in the structure in server unit 20.Otherwise or also can in plotting unit 30, there is the function (in these cases, plotting unit 30 also can be considered as not existing) of server unit 20.In addition, the function of plotting unit 30 is the general on-screen data generation of existing existence, editor's subsidiary function., thus arbitrarily user auxiliary carry out on-screen data arbitrarily newly-generated/operation upgraded generates new on-screen data.In addition, it is same with prior art on the on-screen data (source code) that generates is basic, be drawn after the not shown editing machine editor that device 30 has, to programable display 10 distributions such as grade, in the present invention, will not describe this editing and processing one by one but by its omission.

In addition, said in this explanation " on-screen data " is not only the application screen data (existing general on-screen data) that each user generates arbitrarily, for example, also comprise on-screen data that display manufacturer provides etc.In other words, " on-screen data " refers to, is used for carrying out certain demonstration and accepts total data/program of inputting in programable display.

Herein, first, the feature of illustrated Display Management System is roughly illustrated.

First, in prior art, for example in plotting unit (servicing unit), generate new on-screen data (newly-generated version, upgrade version etc.) by user, this on-screen data is downloaded to programable display and keeps, carries out from plotting unit.In addition, in prior art, be replaced with new programable display in the fault because of programable display etc., the on-screen data that plotting unit is kept downloads to new programable display and keeps, implements from plotting unit.

In contrast, in the method, for example, as an example, can adopt the mode from plotting unit (servicing unit) 30 to the download of the on-screen data of programable display 10 according to existing method, but also can adopt the mode of not carrying out downloading.Adopting not when the mode from plotting unit (servicing unit) 30 to the download of the on-screen data of programable display 10, from plotting unit 30, on-screen data is forwarded and preserved to server unit 20, and download to corresponding programable display 10 from server unit 20.

But this is an example, as other example, same with prior art as mentioned above, also can carry out the download of the on-screen data from plotting unit 30 to programable display 10.But, the in the situation that of these other examples, on-screen data must be forwarded and back up preservation from programable display 10 to server unit 20.In addition, now, also can check the on-screen data forwarding to server unit 20 whether normal, only in normal situation, this on-screen data is stored in server unit 20.Thus, can tackle because of situations such as the on-screen datas such as garble are damaged.

The in the situation that of an above-mentioned example, plotting unit 30 for example, in the time of the above-mentioned new on-screen data of each generation (first edition or upgrade version etc.), is all distributed this on-screen data preserve to server unit 20.Now, information identification for (display use certain identify with ID or IP address etc.) that keeps, carries out the programable display 10 of this on-screen data is also sent and is kept at server unit 20 sides together.In server unit 20, for example, in the time preserving the on-screen data of distribution, preserve accordingly above-mentioned identification information.

Server unit 20 downloads to respectively in corresponding programable display 10 being distributed to each on-screen data of self also preserving.For example, in the time having the new on-screen data sending from plotting unit 30, preserve the on-screen data that this point sent, and download in corresponding programable display 10.But, be not limited to this example.For example also can have a guide look of the programable display that shows that registration is complete, allow user select programable display arbitrarily, thus this on-screen data be downloaded in the programable display of this selection.

In addition, the in the situation that of an above-mentioned example, for example, also can be arranged in newly-installed programable display 10, not keep in advance on-screen data.In the case, can certainly will on-screen data that should programable display 10 be distributed and be preserved to server unit 20 from plotting unit 30.Also can download corresponding on-screen data and keep by the programable display 10 from server unit 20 to this original state, thereby can make this programable display 10 entrys into service.

In a word, also the on-screen data of each programable display 10 can be stored in server unit 20, thus, for example, in the case of the on-screen data of programable display 10 disappears arbitrarily for a certain reason, the on-screen data that also can back up with server unit 20 is by its recovery.Or, the on-screen data of preserving in plotting unit 30 is for a certain reason lost and plotting unit 30 no longer plays a role, also (for example can work on, break down and change in the situation that, use the on-screen data of backup in server 20 at programable display 10).

In order to realize aforesaid operations, for example, as an example, the structure that adopts each programable display 10 can communicate by letter with server unit 20 via certain network with plotting unit 30.This network is for example the internal network such as null modem cable, LAN, internet etc.So programable display 10 also has the communication function communicating via network, such as distributing IP address etc.

On the other hand, server unit 20 also can be described as the on-screen data that can adopt the mode of centralized management to save multiple programable displays 10 from damage.Server unit 20 particularly, in the case of the on-screen data via the each programable display 10 of internet management, can adopt the mode of centralized management to save the on-screen data of multiple programable displays 10 from damage.Server unit 20 is for example to provide the on-screen data of this centralized management and saves the operator's of service server from damage, but is not limited to this example.

Server unit 20 also can have as providing on the internet on-screen data to save the function of the Web server of service from damage.Server unit 20 for example provides the beginning of service, the service such as registration, the renewal of on-screen data of programable display on the internet.In the case, plotting unit 30 has function of browse, and server unit 20 for example shows and is used for accepting the not shown picture that above-mentioned service starts and registers on this browser menu.The user of plotting unit 30, on this not shown picture, carries out starting and the input operation of registering etc. for above-mentioned service.

In the time starting to provide this service, as an example, from carrying out the management of the on-screen data of more than one programable display 10 arbitrarily (generation, preservation, editor's etc.) plotting unit 30, entrust and start to provide service to server unit 20 via network.Now, plotting unit 30 sends the relevant regulations information of self programable display 10 of managing of device (certain identification of using of display with ID, IP address etc.) register to server unit 20.Server unit 20 carries out saving from damage, managing of this on-screen data to registered programable display 10.

, for example, in the time having new registration, server unit 20 is carried out and is used for the on-screen data of registered programable display 10 to be kept at the processing in self installing.In addition, server unit 20 is in the time that the on-screen data of preserving has certain to upgrade (upgrading etc.), and enforcement obtains upgraded edition and is kept at the processing of self installing.

Also can take several different methods to realize these processing.For example, obtain on-screen data new or upgraded edition from the programable display 10 as object (for example, according to backup request described later) via network.Or, plotting unit 30 also can be distributed on-screen data new or upgraded edition storage (in the case, can also forward from server unit 20 to programable display 10 on-screen data new or upgraded edition) to server unit 20 via network.

In any case, according to becoming the state that the on-screen data identical on-screen data keeping with registered each programable display 10 is remained on to server unit 20 sides, carry out certain processing.

In addition, also can utilize the on-screen data that remains on above-mentioned server unit 20 sides, whether the on-screen data that inspection programable display 10 keeps is tampered.

Herein, although the possibility that the on-screen data keeping in server unit 20 sides is tampered is not for " 0 ", lower with programable display 10.

Thus, for programable display 10 arbitrarily, in the on-screen data keeping at this display 10 and the inconsistent situation of on-screen data keeping in server unit 20 sides, being considered as the on-screen data that this display 10 keeps has the possibility being tampered.In the inconsistent situation of on-screen data, (there is the possibility of distorting), if when programable display 10 is startup, do not allow to start, if quit work in the course of work.Because distorting the not shown PLC main body abnormal operation being connected with programable display 10, so, the likely abnormal operation of various control object equipment being connected with PLC main body, therefore, operator's health is also likely caused danger.In the method, before work starts and in the course of work, have or not and distort the generation that can prevent/control this abnormal conditions by inspection.

After becoming permission (OK) and start working in the time that programable display 10 starting or while startup, use at any time or termly in the course of the work the on-screen data that is maintained at server unit 20 sides, the on-screen data of inspection programable display 10 sides has or not to be distorted.Thus, even in the case of the on-screen data of programable display 10 sides maintenances, execution is tampered, the possibility that can tackle before problem becomes is seriously large.

In a word, in the method, the on-screen data that first each programable display 10 is kept, carried out remains in server unit 20, thus, for example, can realize following object.

No longer include on-screen data and only stay the situations such as programable display 10 sides, even if programable display 10 breaks down, also can guarantee that on-screen data can not lose.

Can check the on-screen data of programable display 10 sides to have or not and distort, while particularly startup, test, can make it not start detecting be tampered in the situation that.In addition, in the course of the work by any time/inspection is distorted termly, in the situation that distorting, can tackle immediately thus.

Below, various structures, the function etc. of the Display Management System shown in Fig. 1 are described in detail.

As already described, illustrated Display Management System has: programable display 10, server unit 20, plotting unit (servicing unit) 30.Not special expression in figure, programable display 10 and server unit 20 are connected to the network, can mutually carry out data transmit-receive.This network is for example the external networks such as the internal network such as null modem cable, LAN, internet.In addition, programable display 10 is connected with external unit 100 (PLC main body and control object equipment etc.), but this is not illustrated especially.

In addition, plotting unit 30 as prior art, for example, can be communicated by letter with programable display 10 via the internal network such as null modem cable, LAN.As prior art, plotting unit 30 also can download to via above-mentioned internal network the on-screen data generating in installing at self in programable display 10, but is not limited in the method this example.As mentioned above, can be also plotting unit 30 sends via said external network mode from the on-screen data generating in installing at self to server unit 20.Certainly, in the case, plotting unit 30 can be communicated by letter with server unit 20 via above-mentioned network.

Above-mentioned programable display 10 is for example illustrated example, has the first memory 11, the operation control part 12 etc. that keep on-screen data.The on-screen data being stored in first memory 11 is the on-screen data that this programable display is used, and this programable display 10 uses this on-screen data to show above-mentioned supervision/control interface etc.

In addition, well-known, on-screen data is generation corresponding to each programable display substantially.So, be maintained at the on-screen data complete difference substantially in each programable display 10.In addition, thus, when any on-screen data of server unit 20 in the screen data group that self is kept forwards to programable display 10, (certainly) is to forward to the programable display corresponding with this on-screen data 10.Certainly, the not special in the drawings expression of server unit 20, but maintenance represents the information of corresponding which programable display 10 of which on-screen data.

To be described in detail operation control part 12 in the back, summary, the on-screen data of making according to on-screen data judging part 2 described later consistent/inconsistent judged result, control the action of this programable display 10.

Server unit 20 has the second memory 21 of each on-screen data that keeps multiple programable displays 10 etc. substantially.In addition, server unit 20 can also have any above (can be also whole) of not shown various function parts, will describe them in the back.

In addition, also can at least in the one (can be also both) in programable display 10 and server unit 20, forwarding portion 1 be set, in programable display 10 and server unit 20 at least one (can be also both), on-screen data judging part 2 be set.

Forwarding portion 1 carries out the forward process of the on-screen data between programable display 10 and server unit 20.That is, utilize forwarding portion 1 in moment arbitrarily, any one of programable display 10 and server unit 20 forwards on-screen data of own maintenance to other one via network.

For example, the forwarding portion 1 of server unit 20 forwards any on-screen data in each on-screen data being maintained in second memory 21 to corresponding programable display 10.The programable display 10 that has received this on-screen data is for example kept at the on-screen data receiving in the first memory 11 of oneself.Or whether the on-screen data that for example utilizes on-screen data judging part 2 to judge to receive is with to remain on on-screen data in first memory 11 consistent.Check and have or not on-screen data to distort by carrying out this consistent/inconsistent judgement.

Or the forwarding portion 1 of for example programable display 10 forwards the on-screen data remaining in first memory 11 to server unit 20.The server unit 20 that has received this on-screen data is for example kept at the on-screen data receiving in second memory 21.Or whether the on-screen data that utilizes on-screen data judging part 2 to judge to receive is with to remain on on-screen data in second memory 21 consistent.Check and have or not on-screen data to distort by carrying out this consistent/inconsistent judgement.Server unit 20 notifies this judged result to programable display 10.

On on-screen data judging part 2 is basic, judgement is maintained at on-screen data in first memory 11 whether with to remain on on-screen data in second memory 21 consistent.Therefore,, as an example, as mentioned above, the on-screen data remaining in any one of programable display 10 and server unit 20 is forwarded to another one, thereby it is consistent/inconsistent that two on-screen datas are compared to judgement each other, but be not limited to this example.For example, not relatively on-screen data each other, but relatively more corresponding with on-screen data only check code (such as cryptographic hash and crc value etc.), judgement is consistent/inconsistent carry out on-screen data consistent/inconsistent judgement.Certainly, at check code each other in inconsistent situation, remain on on-screen data in first memory 11 and to remain on on-screen data in second memory 21 inconsistent.

Operation control part 12 according to above-mentioned on-screen data judging part 2 above-mentioned consistent/inconsistent judged result (have or not and distort) controls the action of this programable display 10.For example, when programable display 10 starts, had or not the judgement of distorting by on-screen data judging part 2.Thus, operation control part 12 in the time starting above-mentioned consistent/be judged as inconsistent (distorting) in inconsistent judgement, do not allow to start and enter error pattern.Under error pattern, for example, carry out alarm output.

On the other hand, in the time starting above-mentioned consistent/be judged as consistent (without distorting) in inconsistent judgement, operation control part 12 allows to start and carries out to start and process, and enters mode of operation.Under mode of operation, carry out common processing action.So programable display 10 uses on-screen data carry out the demonstration of above-mentioned supervision/control interface and accept the processing such as input.

Form according to the mode of carrying out the on-screen data forward process between programable display 10 and server unit 20 by above-mentioned forwarding portion 1, for example, not only can be by the on-screen data back-up storage of programable display 10 in server unit 20, and can carry out the processing of above-mentioned on-screen data judging part 2 and operation control part 12.

In addition, server unit 20 can also have display registration/selection portion 22.

As mentioned above, the programable display arbitrarily 10 of display registration/selection portion 22 new registrations.In above-mentioned example, represent from plotting unit 30 via the network registration example of display arbitrarily., each plotting unit 30 keeps the on-screen data of one or more programable displays 10 of management separately conventionally, also keeps certain information (identification id and IP address etc.) about these programable displays 10.Thus, also can send (can also be on-screen data) such as above-mentioned IP addresses and entrust registration to the display registration/selection portion 22 of server unit 20 via external network from plotting unit 30, thus display registration/selection portion 22 these information of storage.

But be not limited to this example.Such as user waits also can carry out the new registration action of programable display 10 arbitrarily by manual action (action keyboard etc./insertion external memory storage) on server unit 20.In a word, although not special expression in figure, in server unit 20, storage is about the information of the regulation of the programable display 10 of registration.

Thus, display registration/selection portion 22 for example also can have by guide look and shows the complete programable display 10 of registration etc., allows user select the function of programable display 10 arbitrarily.In addition, server unit 20 also can be carried out certain processing to the programable display 10 of selecting.This processing example in this way the uploading of download, on-screen data (back-up storage) of on-screen data or inspection on-screen data has or not and distorts etc.In addition, also can allow user in above-mentioned guide look display frame, select the processing of wanting.

In addition, server unit 20 can also have Standby control portion 23.

On Standby control portion 23 is basic, (be for example the display of being selected by display registration/selection portion 22 from the programable display 10 of handling object arbitrarily, but be not limited to this example), obtain the on-screen data in the first memory 11 that is maintained at this programable display 10, this on-screen data is stored in second memory 21.But, except this basic function, can also there are the data that obtain from programable display 10 of confirmation whether normally, only under normal situation, be stored in the second function of depositing in storer 21.For example, even if it is normal to remain on on-screen data itself in first memory 11, server unit 20 is also likely according to receiving because of certain abnormal mode of the generations such as garble.In Standby control portion 23, after confirming that obtained on-screen data is not abnormal, be stored in second memory 21.

Therefore, Standby control portion 23 receives from the on-screen data that the programable display 10 of handling object sends arbitrarily, this on-screen data is temporarily stored in certain storage part beyond second memory 21, and this on-screen data is returned and send consistent confirmation request to the programable display 10 of transmit leg immediately.

Whether the on-screen data of receiving above-mentioned passback at programable display 10 side joints is with after consistent confirmation request, utilize on-screen data that on-screen data judging part 2 judges this passback with to be stored in on-screen data in first memory 11 consistent.This judged result is replied to server unit 20.

Thus, the Standby control portion 23 of server unit 20 is " unanimously " in the judged result of replying, and the on-screen data of above-mentioned temporary transient storage is kept in second memory 21.On the other hand, be " inconsistent " in the judged result of replying, the on-screen data of discarded above-mentioned temporary transient storage.In addition, then also can again from the programable display 10 of handling object, obtain on-screen data.Certainly, in the case, also return this on-screen data and send consistent confirmation request.Also repeatedly this processing until obtain " unanimously " judgement and on-screen data is kept in second memory 21.

Or, as mentioned above, on-screen data is not temporarily stored in not shown storage part, also can temporarily on-screen data be stored in second memory 21.Then,, with above-mentioned same, passback on-screen data also sends consistent confirmation request.Be " inconsistent " in the judged result of replying, delete the on-screen data being stored in second memory 21.In addition, in the case, also can again obtain on-screen data from the programable display 10 of handling object.Certainly, in the case, also this on-screen data be stored in second memory 21 and return and send consistent confirmation request.Also this processing repeatedly, until obtain the judgement of " unanimously ".Certainly,, in the case of obtaining the judgement of " unanimously ", become on-screen data and be stored in the state in second memory 21.

As mentioned above, store normal on-screen data in second memory 21, then, the above-mentioned reliability of the judgement processing of distorting etc. that has or not that uses that this on-screen data carries out is high.

In addition, server unit 20 can also have on-screen data forwarding distribution portion 24.In addition, simultaneously, plotting unit 30 also can have on-screen data distribution portion 31 thus.

Herein, first plotting unit 30 is described.Plotting unit 31 also has not shown subsidiary function portion 32.This subsidiary function portion 32 itself is existing function, be assisted user generate/edit/upgrade the function of the on-screen data arbitrarily of programable display 10 use arbitrarily.The on-screen data of the new or upgraded edition being generated by this subsidiary function portion 32 is downloaded in above-mentioned programable display arbitrarily 10.This function is also existing capability, not special expression in figure.

Above-mentioned on-screen data sending part 31 is function parts of the on-screen data of the new or upgraded edition of above-mentioned any generation being distributed to server unit 20 via network.In addition, now, also distribute together the information (above-mentioned identification ID and IP address etc.) that represents the programable display 10 corresponding with this on-screen data.

The above-mentioned on-screen data of server unit 20 forwards distribution portion 24 on-screen data of being distributed by on-screen data distribution portion 31 is stored in second memory 21, and distributes to corresponding programable display 10.Thus, this programable display 10 is stored in the on-screen data of distribution in first memory 11.In addition,, in the case of the on-screen data of distribution upgraded edition, also can delete the on-screen data that is stored in the old edition in second memory 21 and first memory 11.

In addition, on-screen data forwards and also can possess the function roughly the same with " on-screen data that inspection institute obtains whether because of garble etc. abnormal function occurs " of above-mentioned Standby control portion 23 in distribution portion 24.But, in the case, return on-screen data to plotting unit 30, so also must possess the function of on-screen data judging part 2 in plotting unit 30.

In addition, server unit 20 can also have subsidiary function portion 25.

Subsidiary function portion 25 can be also the function part identical with the subsidiary function portion 32 of above-mentioned plotting unit 31.

In the case, for example, when generated the on-screen data of new or upgraded edition of programable display 10 use arbitrarily by subsidiary function portion 25, server unit 20 (for example on-screen data forwards distribution portion 24) is stored in the on-screen data of this generation in second memory 21, and distributes to corresponding programable display 10.

Fig. 2 is the action case (one) of aforementioned display device management system.

First, in the method, identical on-screen data is kept to programable display 10 and server unit 20 in both (as long as no distorting etc.) on basic.Be described for this action, below, with reference to Fig. 2, one example is carried out to simple explanation.

As mentioned above, generate new on-screen data (new or upgraded edition) in plotting unit 30 time, plotting unit 30 is distributed this new on-screen data and is kept in corresponding programable display 10 or server unit 20.

Herein, first, the mode that above-mentioned new on-screen data is distributed to corresponding programable display 10 from plotting unit 30 is described.

In the case, first, programable display 10 is kept at the on-screen data of distribution in first memory 11.On the other hand, plotting unit 30 has for example been distributed the information (identification ID etc.) of the programable display 10 of above-mentioned on-screen data to server unit 20 notices.Or, carry out the new registration of this programable display 10.Or the programable display 10 that has been distributed above-mentioned new on-screen data is notified this content to server unit 20.

Thus, for example aforementioned display device registration selection portion 22 has the function that shows the complete programable display complete list of registration as mentioned above, and, wherein also can display update the complete list of the programable display of on-screen data and the programable display of new registration.

For example, the programable display that user etc. show from guide look, select arbitrarily, after programable display, to carry out the processing of the on-screen data of the selected programable display of back-up storage.For example, above-mentioned Standby control portion 23 carries out these processing, but is not limited to this example.Or, even if user does not select, for all programable displays 10 that have on-screen data renewal etc., also can automatically carry out the processing of this on-screen data of back-up storage.

For example, Standby control portion 23 sends backup request (S1) to the programable display 10 of above-mentioned selection.Thus, the programable display 10 that receives this backup request is for example by its forwarding portion 1, and the on-screen data being kept in self first memory 11 is sent to (S2) to server unit 20.Certainly, now, also send together the identifying information (identification ID and IP address etc.) of the display 10 of transmit leg.Server unit 20 receives after these on-screen datas, is kept in self second memory 21 (S3).In addition, now, also can carry out the abnormal test processing (garble etc.) of above-mentioned Standby control portion 23.

But, be not limited to above-mentioned example.For example, even if user does not select one by one, also can automatically from the programable display 10 as object, obtain on-screen data back-up storage.As mentioned above, the programable display 10 after on-screen data upgrades and the programable display 10 of new registration can be differentiated, so also can automatically send above-mentioned backup request to these each programable displays 10.

As mentioned above, server unit 20, in the case of the on-screen data of the programable display 10 of registration is updated, obtain the on-screen data of this upgraded edition, and back-up storage is in the second memory 21 of self from this programable display 10.Or server unit 20, in the case of the new registration that has programable display 10, is obtained this on-screen data from this programable display 10, and by its back-up storage in the second memory 21 of self.Like this, all the time, make (if not distorting etc.) to be stored in on-screen data in first memory 11 and to be stored in on-screen data in second memory 21 identical.

Below, the mode that above-mentioned new on-screen data is distributed to server unit 20 from plotting unit 30 is described.In addition, now, plotting unit 30 also sends the identifying information (IP address etc.) of the display 10 corresponding with this on-screen data together.

In the case, server unit 20 is stored in the new on-screen data of above-mentioned distribution in self second memory 21 (S4).Then, the new on-screen data being stored in second memory 21 is distributed to (download) (S5) to corresponding programable display 10.In addition, also can automatically carry out this download, or also can show and allow user select by above-mentioned guide look, thereby distribute (download) to the programable display 10 of selecting.In addition, do not describe one by one, as mentioned above, in server unit 20, can differentiate programable display 10 and new programable display 10 of registering after on-screen data upgrades, show this programable display 10 so can have a guide look of, this programable display 10 is downloaded to new on-screen data automatically.

In a word, the programable display 10 that sends new on-screen data (download) from above-mentioned server unit 20 is kept at downloaded on-screen data self first memory 11 (S6).

In addition, be not limited to this example, for example, above-mentioned new on-screen data also can be in server unit 20 waits the 25 at random generations by above-mentioned subsidiary function portion by developer.In the case, server unit 20 is stored in this new on-screen data in second memory 21, and distributes (download) (S5) to corresponding programable display 10.

In addition, do not describe one by one, certainly, in the time of communication, also receive and dispatch together the information that represents the transmit leg/sending destinations such as IP address.

As mentioned above, whether on basic, (if not distorting) makes to be stored in on-screen data in first memory 11 and to be stored in on-screen data in second memory 21 identical, thereby utilize these data to check like that as described below the on-screen data that remains on programable display 10 sides to be tampered.

This is distorted inspection and processes at any time/execution termly in the time of the startup of programable display 10 or in the course of work.

Distort inspection processing if start this,, in the example of Fig. 2, first, programable display 10 sends judgement request (S7) to server unit 20.The server unit 20 that receives this judgement request sends on-screen data request (S8) to requesting party's programable display 10.The programable display 10 that receives this on-screen data request sends (S9) by the on-screen data being stored in self first memory 11 to server unit 20.

In addition, be not limited to above-mentioned example, for example, also can not carry out the processing of above-mentioned S7, S8, but also send together judgement request in the time of the processing of S9, in server unit 20, carry out on-screen data about sending in S9 unanimously/inconsistent judgement.

The server unit 20 that has received the on-screen data that judges object according to the processing of above-mentioned S9 carries out unanimously/inconsistent judgement by the on-screen data judging part 2 of self.That is, the on-screen data that server unit 20 (its on-screen data judging part 2) relatively receives and the on-screen data being kept in self second memory 21, judgement is consistent/inconsistent (have or not and distort).Judged result is replied to programable display 10 (S10).

The programable display 10 that has received this judged result is carried out the action corresponding with the judged result receiving by its operation control part 12.For example, distorting in inspection processing in the time starting, is consistent (OK: consistent in judged result; Without distorting) situation under, operation control part 12 allows to start and entrys into service (entering mode of operation).In addition, for example distorting in inspection processing in the time starting, is inconsistent (NG: inconsistent in judged result; Have and distort) situation under, operation control part 12 not permit can start, for example enter error pattern.

In addition, for example, in the course of the work at any time/distorting in inspection processing of execution termly, is consistent (OK: consistent in judged result; Without distorting) situation under, operation control part 12 remains in operation.On the other hand, be inconsistent (NG: inconsistent in judged result; Have and distort) situation under, operation control part 12 shuts down, for example, enter error pattern.

Herein, by way of exception, server unit 20 is not preserved on-screen data in the second memory 21 of self, replys this content to display 10, or replys consistent (OK: without distorting) as judged result to display 10.Thus, the processing in the time starting, force start display 10.In addition, in the case, server unit 20 also can be stored in the on-screen data of obtaining from display 10 second memory 21, but also can resend above-mentioned backup request.

But, be not limited to this example, for example, in the processing of above-mentioned S9, as mentioned above, also can not send on-screen data, but send the check code corresponding with on-screen data.In the case, server unit 20 (its on-screen data judging part 2) judges that whether the check code that receives is consistent with the check code corresponding with being kept at on-screen data in self second memory 21, thereby judges whether consistent.

Fig. 3 is the action example (its two) of aforementioned display device management system.

In addition, the difference of Fig. 3 and Fig. 2 is, on-screen data judging part 2 is arranged in server unit 20 in Fig. 2, is arranged in programable display 10 this point in Fig. 3.Therefore, the action of Fig. 3 is slightly different from the action of Fig. 2, but identical action is also many, so, below only to describing with the difference of Fig. 2, the explanation of the roughly the same action of omission or simplification and Fig. 2.

In Fig. 3, have or not the action of distorting to describe to being used for judging.

In the situation of Fig. 3, programable display 10 is carried out and is had or not the judgement processing of distorting termly in the time starting or in the course of work.If start to carry out this processing, first, send on-screen data request (S11) to server unit 20.Thus, server unit 20 (its forwarding portion 1) sends (S12) by the on-screen data being kept in self second memory 21 to requesting party's display 10.

Thus, the on-screen data judging part 2 of display 10 is carried out the on-screen data that is kept at server unit 20 sides and consistent/inconsistent judgement (judgement have or not distort) that is kept at the on-screen data in self first memory 11.The operation control part 12 of display 10 is carried out the action control of this display 10 according to the judged result of on-screen data judging part 2 (have or not and distort).This is illustrated, so the description thereof will be omitted.

In addition, when server unit 20 receives above-mentioned on-screen data request, in the second memory 21 of self, do not have on-screen data, this situation is replied to requesting party's display 10.Thus, the on-screen data judging part 2 of display 10 is considered as not distorting forcibly.Thus, operation control part 12 particularly allows to start in the time starting, thereby enters above-mentioned mode of operation.Thus, can prevent the situation that programable display 10 cannot start.

In addition, in the case, server unit 20 becomes the state of the on-screen data of this display 10 of back-up storage immediately.That is, after server unit 20, send backup request immediately to above-mentioned on-screen data requesting party's display 10, the display 10 that has received this request sends the on-screen data being kept in self first memory 11 to server unit 20.The server unit 20 that has received this on-screen data is kept at this on-screen data in the second memory 21 of self.Certainly, now also can carry out the inspection processing (inspection whether because of the reasons such as garble produce extremely) of above-mentioned Standby control portion 23 in the on-screen data receiving.

Fig. 4～Fig. 8 represents the sequence of movement of the each processing action shown in above-mentioned Fig. 2 and Fig. 3.

In addition,, in Fig. 4～Fig. 8, be expressed as in the drawings " POD10 " in order to simplify programable display 10.Equally, in order to simplify, server unit 20 is expressed as " server 20 " in the drawings.

First, Fig. 4 (a) represents the sequence of movement of backup actions.

As already described, as an example, also can utilize the display registration selection portion 22 of server unit 20 to show that user can select the not shown selection picture of required display etc., in this selection picture, guide look shows the programable display 10 that registration is complete, allows user select display 10 arbitrarily.In addition, can also have a guide look of and show various instructions, select for user, for example, have " backup " instruction etc.

Thus, in above-mentioned selection picture, user selects required programable display 10 to select after " backup " instruction simultaneously, and server unit 20 sends above-mentioned backup request to selected display 10.In addition, as already described, be not limited to such example, server unit 20 for example, in the case of the programable display 10 that has new registration, also can send backup request to this display 10.Or server unit 20 is for example distributed the notice of on-screen data of upgraded edition to programable display 10 arbitrarily in the case of having from plotting unit 30, also can send backup request to this display 10.Or, as mentioned above, have or not while distorting in judgement, also can be in the case of not sending backup request the on-screen data corresponding with the second memory 21 of self.

The display 10 that has received above-mentioned backup request sends the on-screen data being stored in self first memory 11 to server unit 20.Server unit 20 is kept at the on-screen data receiving in the second memory 21 of self.In addition, now also can carry out above-mentioned " whether the on-screen data that inspection receives is normal ", be only kept under normal circumstances in second memory 21.

For example, the on-screen data of as mentioned above, registering each complete display 10 in server unit 20 sides is for example stored in, in the second memory 21 of this server unit 20,, also can according to referring to Fig. 4 (b) illustrated like that for distorting judgement, but be not limited to this.For example, in the case of remaining on for a certain reason the on-screen data of display 10 sides disappears, thereby by back-up storage the on-screen data in server unit 20 download in display 10 can be corresponding.Particularly not in the situation such as normal work, especially bring into play significant effect at plotting unit 30 for a certain reason.

Or, in the case of breaking down, programable display 10 is replaced with new programable display 10, and the on-screen data by back-up storage in server unit 20 downloads in new display 10, thereby can be corresponding.But, in the case, the identifying information of each programable display 10 for example, must changing from plotting unit 30 to server unit 20 notices in advance and after changing etc.

In a word, preserve the on-screen data of each programable display 10 in server unit 20 sides, particularly preferably preserve suitable on-screen data.Suitable on-screen data refers to, such as upgraded edition (latest edition) on-screen data or normal on-screen data etc. (as mentioned above, discarded because of garble etc. become abnormal on-screen data).

For backing up, for distorting judgement, while downloading to one of them of display 10, the on-screen data that is kept at server unit 20 sides is important, in the time occurring in server unit 20 sides and do not preserve the situation of suitable on-screen data, must solve as early as possible this abnormal conditions.An example for this processing illustrates.

Fig. 4 (b) is the figure of the sequence of movement while representing to start.

In addition, this is the sequence of movement corresponding with Fig. 2., represent that on-screen data judging part 2 is positioned at the situation of server unit 20 sides, but as mentioned above, be not limited to this example.

In programable display 10, the operating powers such as user are connected or are started after replacement, and display 10 starts to start to be processed, and first, sends above-mentioned judgement request to server unit 20.The server unit 20 that has received this judgement request is replied display 10 as response by above-mentioned " on-screen data request ".Thus, display 10 sends the on-screen data being kept in self first memory 11 to server unit 10.

Thus, whether consistent the on-screen data that server unit 20 relatively receives and the on-screen data being kept in self second memory 21, judge both.Judged result is replied to display 10.For example, in the situation that both are consistent, will check consistent (OK: without distorting), in inconsistent situation, will check inconsistent (NG: distort) to reply display 10.

Thus, in the situation that replying inspection consistent (OK), display 10 continues to start to be processed, and enters common duty (mode of operation) after startup.On the other hand, in the situation that replying inspection inconsistent (NG), end to start and process, enter error pattern, for example, export alarm etc.

Like this, in the situation that likely distorting, do not allow the startup of display 10.In the situation that on-screen data is tampered, programable display 10 abnormal operations, thus, likely abnormal operation of external unit 100 (PCL main body and control object equipment etc.).In the method, can prevent this abnormal conditions.

In addition, not only in the time starting, as shown in Fig. 5 (a), (b), in the course of the work also at any time/carry out termly the above-mentioned judgement of distorting, like this, even do not distort in the time starting, the in the situation that of distorting in the course of the work after startup, detected immediately and shut down etc., can be reduced thus the possibility that above-mentioned abnormal conditions occur.

For example, as shown in 5 (a), programable display 10 for example sends the on-screen data being kept in self first memory 11 termly to server unit 20.In addition now for example also preferably send together, the instruction of the regulations such as above-mentioned judgement request.

The server unit 20 that has received this on-screen data (and judging request etc.) judges that received on-screen data is whether with to be kept at on-screen data in self second memory 21 consistent, judges thus that the on-screen data that remains on programable display 10 sides has or not to distort.Judged result is replied to display 10.For example, in the situation that both are consistent, will check consistent (OK: without distorting), and in inconsistent situation, check inconsistent (NG: distort) to reply display 10.

Inspection consistent (OK) in the situation that, programable display 10 works on, and the in the situation that of inspection inconsistent (NG), for example, after the measure such as take to quit work, enters error pattern, carries out alarm output etc.

Above-mentioned on-screen data consistent/inconsistent judgement processing (on-screen data is distorted judgement) in, use on-screen data itself, be still not limited to this example.For example, also can use the only check code corresponding with on-screen data (such as cryptographic hash and crc value etc.).

Fig. 5 (b) is illustrated in the above-mentioned sequence of movement that uses the example of cryptographic hash in judgement processing of distorting.

The cryptographic hash of the on-screen data that programable display 10 is for example preserved self in the course of the work termly sends to server unit 20.In addition now for example preferably also send together, the instruction of the regulations such as above-mentioned judgement request.In addition all generate, the cryptographic hash of on-screen data in display 10 1 sides at every turn.

Server unit 20 judges that the cryptographic hash of the on-screen data whether cryptographic hash that receives preserve with self is consistent.In addition, now also can all generate in server unit 20 1 sides the cryptographic hash of on-screen data at every turn, but also can generate and store in advance.

In the situation that cryptographic hash is consistent, server unit 20 is replied inspection consistent (OK: without distorting) to display 10, rechecks next time and tests inconsistent (NG: distort) in inconsistent situation.

In addition, also can replace cryptographic hash and for example use crc value etc.

Fig. 6 represents to use the example of the molar behavior order in the situation of above-mentioned cryptographic hash.

In illustrated example, in server unit 20, user registers selection portion 22 by aforementioned display device and selects display 10 arbitrarily, sends above-mentioned backup request to the display 10 of this selection.In addition, as already described, send backup request and be not limited to such situation, the description thereof will be omitted herein.

The display 10 that has received above-mentioned backup request sends the on-screen data being kept in self first memory 11 to server unit 20.Server unit 20 is kept at the on-screen data receiving in self second memory 21 (in addition, before this, also can be described above, whether the on-screen data that inspection receives is normal, only in normal situation, be kept in second memory 21), and calculate the cryptographic hash of the on-screen data that receives, and be kept in storer etc.In addition, in figure not represent, but also can by the generation of the preservation of on-screen data and cryptographic hash, preserved notify to display 10.

In addition, certainly, cryptographic hash consistent/inconsistent expression on-screen data consistent/inconsistent.

Then, display 10 carry out for the above-mentioned course of work at any time/processing that regular judgement is distorted.

; display 10 is for example on-screen data of reading and saving in the first memory 11 of self termly in the course of the work; and this on-screen data is intactly sent to server unit 20, or calculate the cryptographic hash of this on-screen data, and this cryptographic hash is sent to server unit 20.

Herein, if to using the example of cryptographic hash to describe, server unit 20 receives after above-mentioned cryptographic hash, the cryptographic hash relatively receiving be kept at the cryptographic hash in above-mentioned storer, whether unanimously judge both.Server unit 20, in the situation that cryptographic hash is consistent, is replied inspection consistent (OK: on-screen data is not distorted) to display 10, rechecks next time and tests inconsistent (NG: on-screen data is distorted) in the inconsistent situation of cryptographic hash.

Below, Fig. 7 (a), (b) represent the sequence of movement that above-mentioned Standby control portion 23 tests while processing.

In Fig. 7 (a), server unit 20 such as,, according to above-mentioned certain triggering (user selection, appointment etc.), sends above-mentioned backup request to corresponding programable display 10.

The display 10 that has received this backup request sends the on-screen data being kept in self first memory 11 to server unit 20.The server unit 20 that has received this on-screen data is kept at this on-screen data in the second memory 21 of self.But this is interim preservation just, not established data, is deleted according to assay.

Above-mentioned Standby control portion 23 carries out above-mentioned inspection processing (on-screen data that inspection receives whether because of the reasons such as garble occur abnormal).Therefore, Standby control portion 23 returns (also sending together the instruction of the regulation that is used for abnormal test etc.) by the above-mentioned on-screen data receiving to the display 10 of transmit leg, carries out unanimously/inconsistent judgement in display 10 1 sides, and inspection has or not abnormal.

The display 10 that has received the on-screen data of above-mentioned passback utilizes its on-screen data judging part 2 to judge that this on-screen data receiving is whether with to be kept at on-screen data in self first memory 11 consistent.Judged result (OK/NG: consistent/inconsistent) is sent to server unit 20.Certainly, consistent in the situation that, be consistent (OK), in inconsistent situation, be inconsistent (NG).

In addition, be not limited to this example, for example, Standby control portion 23 also can generate the check code corresponding with the above-mentioned on-screen data receiving, and this check code is returned to the display 10 of transmit leg.In the case, display 10 generates the check code corresponding with being kept at on-screen data in self first memory 11, judge that whether this check code is consistent with the check code of above-mentioned passback, thereby obtain above-mentioned judged result (OK/NG: consistent/inconsistent).

The Standby control portion 23 of server unit 20 carries out the processing corresponding with this judged result (OK/NG: consistent/inconsistent).,, in the situation that judged result is inconsistent (NG), delete the on-screen data being kept in above-mentioned second memory 21.As mentioned above, for example again send backup request to display 10.On the other hand, in the situation that judged result is consistent (OK), work on.

In Fig. 7 (b), server unit 20, according to above-mentioned certain triggering, sends above-mentioned backup request to corresponding programable display 10.

The display 10 that has received this request sends the on-screen data being kept in self first memory 1 to server unit 20.The server unit 20 that has received this on-screen data is temporarily stored in this on-screen data in not shown storer beyond second memory 21 etc.

Above-mentioned Standby control portion 23 carries out above-mentioned inspection processing (on-screen data that inspection receives whether because of the reasons such as garble occur abnormal).Therefore, Standby control portion 23 returns (also sending together the instruction of the regulation that is used for abnormal test etc.) by the above-mentioned on-screen data receiving to the display 10 of transmit leg, carries out unanimously/inconsistent judgement in display 10 sides, and inspection has or not abnormal.

The display 10 that has received the on-screen data of above-mentioned passback utilizes its on-screen data judging part 2 to judge that this on-screen data receiving is whether with to be kept at on-screen data in self first memory 11 consistent.Judged result (OK/NG: consistent/inconsistent) is sent to server unit 20.

The Standby control portion 23 of server unit 20 carries out the processing corresponding with this judged result (OK/NG: consistent/inconsistent).,, in the situation that judged result is inconsistent (NG), delete the on-screen data being temporarily kept in above-mentioned not shown storer.As mentioned above, for example again send backup request to display 10.On the other hand, in the situation that judged result is consistent (OK), the on-screen data being temporarily stored in above-mentioned not shown storer is kept in the second memory 21 of self.

Fig. 8 (a) represents that plotting unit 30 sends the sequence of movement in the mode of on-screen data to server unit 20.

In Fig. 8 (a), plotting unit 30, in the time there is certain on-screen data distribution triggering, sends via network this on-screen data to server unit 20.On-screen data sends to trigger and refers to, for example, for the programable display 10 of being managed by this plotting unit 30, generates the situation of above-mentioned on-screen data newly or upgraded edition, but is not limited to this example.For example, can say and entrust and be newly registered in the medium situation of server unit 20 having generated on-screen data and programable display just in the course of the work 10, produce on-screen data distribution and trigger.

In a word, when the on-screen data of programable display 10 is distributed from plotting unit 30 to server unit 20 arbitrarily, server unit 20 is kept at the on-screen data of this distribution in second memory 21.Server unit 20 also forwards to corresponding programable display 10 on-screen data being kept in second memory 21, distribute.In addition, as already described, plotting unit 30, in the time sending on-screen data, also sends the identifying information of corresponding display 10 etc. together.

Programable display 10 receives the on-screen data that forwards, distributes from above-mentioned server unit 20, and this on-screen data is kept in first memory 11.In addition, certainly, in programable display 10, now use the on-screen data being kept in first memory 11 to carry out work.

Fig. 8 (b) represents that plotting unit 30 is to the sequence of movement in the mode of each programable display 10 download screen data.

In Fig. 8 (b), plotting unit 30, in the time there is certain on-screen data distribution triggering, is distributed (download) by this on-screen data to corresponding programable display 10.In addition, on-screen data distribution now triggers and refers to, for example, generate the situation of on-screen data new or upgraded edition for the programable display 10 of being managed by this plotting unit 30.

Programable display 10 is kept at the on-screen data of downloading from plotting unit 30 first memory 11.Also can will there be the advisorys such as on-screen data renewal to server unit 20, but in illustrated example, carry out this notice by plotting unit 30.Display 10 after for example the on-screen data of download being kept in first memory 11 is successfully notified download to plotting unit 30.

Plotting unit 30 in above-mentioned programable display 10 after download screen data, is notified after above-mentioned download success, notifies the identifying information etc. of the programable display 10 of above-mentioned download side and content that on-screen data upgrades etc. via network to server unit 20.The server unit 20 that has received this notice for example sends above-mentioned backup request to corresponding programable display 10.In addition, as already described, corresponding programable display 10 is the displays that represent above-mentioned identifying information.

As already described, the display 10 that has received above-mentioned backup request sends the on-screen data being kept in first memory 11 to server unit 20, and server unit 20 is kept at received on-screen data in second memory 21.In addition, also can confirm before this that on-screen data is not abnormal.

In addition, as already described, server unit 20 may not be limited to the outside that is connected with external networks such as the internets place of display 10 (particularly away from) computer installation.For example, server unit 20 also can, by internal networks such as LAN, carry out the transmitting-receiving of above-mentioned on-screen data and various instructions etc. with each programable display 10.

But, as an example, at server unit 20, the on-screen data of multiple programable displays 10 is passed through to certain external network (such as internet etc., but be not limited to this example) collect, forward, and carry out in the situation of centralized management, for example can obtain cost-saving effect etc.

; even if also can preserve, manage the on-screen data of multiple programable displays by existing plotting unit (servicing unit), but be fundamentally the management of (each scene/each user etc.) in the built-in system connecting with internal networks such as LAN.The responsible official etc. of management plotting unit all must be set for each scene and each user in addition.
