Embodiment
Embodiment 1.
Fig. 1 is the structural drawing of the error processing system 100 of embodiment 1.
Error processing system 100 is the systems of carrying out the process relevant with the mistake that there occurs in the production equipment 10 forming FA system.Error processing system 100 possesses production equipment 10, PLC20, GOT30 (example of interface arrangement), error database 40, AP server 50 (apps server).
Production equipment 10 has multiple, for each production equipment 10, is provided with PLC20 and GOT30.Be connected respectively by network between production equipment 10 and corresponding PLC20, between PLC20 and corresponding GOT30, between each GOT30 with error database 40, between error database 40 with AP server 50.Network between each GOT30 and error database 40 and between error database 40 and the AP server 50 sometimes traffic is restricted to below regulation.
Fig. 2 is the GOT30 of embodiment 1 and the functional structure chart of error database 40.
GOT30 possesses message storing section 31, error code obtaining section 32, database retrieval portion 33, inner search part 34 and display part 35.
Error database 40 possesses error message storage part 41.
Fig. 3 is the figure that the information that the message storing section 31 of embodiment 1 stores is shown.
Message storing section 31 is GOT30 has, stores error message memory storages in inside.Message storing section 31 is for each error code storage errors message.Error code is the identifier of the mistake that there occurs.Error message is the information of the content representing the mistake that there occurs simply.
Fig. 4 is the figure that the information that the error message storage part 41 of embodiment 1 stores is shown.
Error message storage part 41 is memory storages of storage errors message etc.Error message storage part 41 for each of device id, language and error code, storage errors message and disposes of information.Device id is the identifier of production equipment 10.Language is the identifier of the description language of error message.Error code and error message described above.Disposes of information which type of is implemented for the mistake that there occurs to dispose and wait, whenever to the information becoming reference during error handling.
Fig. 5 is the process flow diagram of the process of the error processing system 100 that embodiment 1 is shown.
Make a mistake in production equipment 10 (S101).PLC20 detects the mistake (S102) that there occurs in production equipment 10.PLC20 is the device controlling the action of production equipment 10/monitor, if so make a mistake in production equipment 10, can easily detect.
So the error code obtaining section 32 of GOT30 obtains the error code (S103) corresponding with the mistake that there occurs from PLC20.Error code obtaining section 32 monitors the internal storage of PLC20, can detect PLC20 and mistake be detected.In addition, error code obtaining section 32 can obtain from PLC20 the error code representing the mistake that PLC20 detects.
If error code obtaining section 32 achieves error code, then database retrieval portion 33 using the language of the device id of the production equipment 10 that is connected to via PLC20, display error message and error code as key word, the error message storage part 41 (S104) of retrieval error database 40.In addition, about the language of display error message, be set to by settings such as the users of GOT30.
The result that retrieved, when having a record corresponding with key word (having in S104), database retrieval portion 33 obtains error message and disposes of information (S105) from this record.Then, display part 35 shows the error message and disposes of information (S107) that are achieved by database retrieval portion 33.
On the other hand, the result that retrieved, (in S104 nothing) when the record not corresponding with key word, inner search part 34 is using error code as key word, and searching message storage part 31, obtains error message (S106).Then, display part 35 shows the error message (S107) achieved by inner search part 34.
Fig. 6 is the figure that the picture example that display part 35 shows is shown.
Display part 35 shows the various measured values 351 relevant with production equipment 10 and makes the switch 352 etc. of production equipment 10 action when usual.In S107, display part 35, in the mode to the information adding shown when usual, shows error message in message display field 353.
In addition, the supvr of error processing system 100, via AP server 50, is suitable for the error message storage part 41 safeguarding error database 40.
Fig. 7 is the figure of the maintenance picture example that error message storage part 41 is shown.
Safeguarding in picture, be presented at the guide look of the information stored in error message storage part 41.Supvr is by selecting the information, the update information press renewing button, lastest imformation that need to safeguard.In addition, supvr presses register button, makes the additional hurdle display of new error code, adds the information relevant with new error code.
The traffic of the network between each GOT30 and error database 40 is restricted to below regulation sometimes.In this case, whenever transfer to the unitary management based on error database 40 from the state of the data of mismanagement code and error message in each GOT30, cannot all data be extracted from each GOT30 and be registered in error database 40.Therefore, be difficult to once by data batchmove to error database 40.
In the error processing system 100 of embodiment 1, about the error code stored in error database 40, GOT30 exports the error message achieved from error database 40, about the error code do not stored in error database 40, exports the error message stored in GOT30.Therefore, in the error processing system 100 of embodiment 1, can apply flexibly the data stored in GOT30 continue use, meanwhile, gradually by data batchmove to error database 40, transfer to unitary manage.
Sometimes researcher etc. are from coming factory abroad.Under these circumstances, the display language of handoff error message is provisionally needed.
In the error processing system 100 of embodiment 1, for the error message registered in error database 40, display language can be switched.Therefore, in the error processing system 100 of embodiment 1, the switching of the display language of interim error message also easily can be tackled.
Usually, when safeguarding GOT30, need the production line stopping comprising the production equipment 10 being provided with GOT30.Therefore, it is possible to the time of implementing the maintenance of GOT30 is very limited.
After having imported error database 40, the message storing section 31 of Maintenance free GOT30 in principle.Therefore, the maintenance of error message becomes easy.In addition, in order to safeguard error message, also without the need to stopping production line.
In addition, the input-output unit of GOT30 is common touch panel, does not possess the keyboard as hardware, and only has the keyboard as software.Therefore, in GOT30, the load of operation to operator of the words such as input error message is large.
After having imported error database 40, the message storing section 31 of Maintenance free GOT30 in principle.Therefore, also alleviate the load of operator simultaneously.
In error database 40, also stored for disposes of information together with error message.Then, GOT30, when showing the error message achieved from error database 40, also shows disposes of information in the lump.By display disposes of information, the time of operator to the error handling that there occurs can be shortened.
As described above, in embodiment 1, gradually data can be shifted to error database 40, transfer to unitary management, but by making to have the project (language, disposes of information etc.) do not had in message storing section in error message storage part, error message can be made more substantial.In addition, if preferentially registration needs the error message of the project (language, disposes of information etc.) do not had in message storing section 31, then useful information can be provided with few labour.
Embodiment 2.
In embodiment 2, the method can carrying out the maintenance of error message is efficiently described.
In embodiment 2, be described centered by the part different from embodiment 1.
When transferring to the unitary management based on the data of error database 40, while the data that detailed survey stores in each GOT30, be registered in error database 40 successively.But in FA system, it is preferential for producing product, operator hurries almost to have no time to attend to the process relevant with error message be truth.Therefore, the structure by really needing preferentially to be registered in the error message of the registration of error database 40 error database 40 is needed.
Fig. 8 is the GOT30 of embodiment 2 and the functional structure chart of error database 40.
The functional structure of GOT30 is identical with the GOT30 of the embodiment 1 shown in Fig. 2.Error database 40, except the function that the error database 40 of the embodiment 1 shown in Fig. 2 possesses, also possesses historical store 42, history efferent 43.
Fig. 9 is the figure that the information that the historical store 42 of embodiment 2 stores is shown.
Historical store 42 is the memory storages information relevant with the mistake that there occurs being stored as history.Historical store 42 storage errors code, device id, generation date-time, recovery date-time, operator ID.Error code and device id described above.It is the information representing the date-time that there occurs mistake that date-time occurs.Restoring date-time is the information representing the date-time that mistake has been eliminated.Operator ID is the identifier of the operator employing GOT30 when there occurs mistake.
Figure 10 is the process flow diagram of the process of the error processing system 100 that embodiment 2 is shown.
The process of S201 to S204 is identical with the process of the S101 to S104 shown in Fig. 5.
If retrieved in S204, then the historical store 42 of error database 40 will have received the date-time of key word as generation date-time, the device id and error code that become key word are mapped with the operator ID of GOT30, are stored as history (S205).In addition, operator ID is registered to GOT30 when the use of GOT30, sends together when being sent to error database 40 by key word.In addition, herein, whether the result that no matter retrieved in S204 has the record corresponding with key word, all stores the history about all error codes retrieved in S204 (all error codes namely achieved in S203).
The process of S206 to S208 is identical with the process of the S105 to S107 shown in Fig. 5.
With reference to the error message etc. shown in S208, operator is to error handling, and mistake is eliminated.So operator presses the carriage return button etc. that input error that GOT30 has eliminates, and eliminates (S209) PLC20 notification error.Now, carriage return button such information that is pressed also is sent to error database 40.The historical store 42 of error database 40 is pressed the date-time of such information as recovery date-time using receiving carriage return button, is stored in the record storing corresponding device id, error code, generation date-time etc. (S210).
If history efferent 43 is via AP server 50, accept instruction from the supvr of error processing system 100, then the history that historical store 42 stores is outputted to AP server 50.Supvr, with reference to the history outputed, via AP server 50, safeguards error message storage part 41.
Such as, history efferent 43 extracts error code in the error code comprised in history, that do not store in error message storage part 41, and the device id etc. stored in the record identical with this error code exports together.Thus, supvr can be informed in error code in the error code do not stored in error message storage part 41, that represent the mistake that in fact there occurs.About the mistake that in fact there occurs, the possibility being thought of as generation is higher than other mistakes, so represent that the error code of this mistake preferentially should safeguard and register such as applicable error message, the error code of disposes of information.
In addition, such as, history efferent 43 is according to generation date-time and restore date-time, calculates and restores the recovery time that spends, exports together with recovery time and device id etc.Extend about recovery time, method of disposal is the possibility of reason to have operator not know.Therefore, represent that the error code of the mistake that recovery time is long preferentially should safeguard and register such as applicable error message, the error code of disposes of information.
In addition, history efferent 43 also can export history according to the arrangement of recovery time order.In addition, history efferent 43 also only can export the information that recovery time is reference time more than.
As described above, in the error processing system 100 of embodiment 2, the history of the mistake that there occurs can be prestored, safeguard error message etc. with reference to history.Therefore, it is possible to the error message really needing to register to error database 40 is preferentially registered in error database 40.
In error database 40 when registration error message, register the error message be more suitable for, and registration disposes of information.Therefore, compared to reference to the error message that registers in GOT30 to error handling, can recovery time be shortened with reference to the error message registered in error database 40 to error handling.Therefore, by by needing the error message of registration to be preferentially registered in error database 40, can recovery time be shortened, and the work efficiency of production line can be improved.
In addition, in history, comprise the operator ID of the operator in fact to error handling.Therefore, supvr, when such as registering the error message about the long error code of recovery time etc., also can register operator ID in disposes of information.Thus, when there occurs identical mistake afterwards, the operator that can determine in fact to this error handling according to operator ID, so from the operator in fact to this error handling, can ask about method of disposal.
In addition, historical store 42 also can go back " disposes of information of operator " that storage list is shown as the disposal content that dealer has carried out.
Such as, after also can pressing carriage return button in S209, can in advance from the disposes of information of menu setecting operator, using the result that have selected as the disposes of information of operator, be stored in historical store 42.In addition, also in a menu, can selecting " other ", when have selected other, the disposes of information of operator can be inputted from other AP server 50.
When safeguarding error message etc. with reference to history, by referring to the disposes of information of the operator of reality, the error message, the disposes of information that are more suitable for can be made.
