Then, it waits for a response from the connected device 4 to this command (step S3).
  • This command includes information (allocated memory address) for specifying an access destination such as the device name 71 and address 72, and the connected device 4 reads data from the storage area indicated by the allocated memory address, and reads the read data. The response process is sent back. However, if data read fails for some reason, a memory read error or the like is returned.

It is determined that it has occurred (step S4, YES), and "error" is stored in the column of the error information 55 in the record corresponding to the processing target record in the shared memory 45 (step S6).

  • step S7 After executing any of the processes in steps S5 and S6, it is checked whether or not an unprocessed record remains in the memory list 101. If it remains (YES in step S7), the process returns to step S2. If it does not remain (step S7, NO), this process ends.
  • FIG. 8 is a processing flowchart of the item processing unit 43. As described above, the processing in FIG. 8 is cyclically executed under the management of the item processing schedule unit 42.

Thereafter, the processes in steps S12 to S19 are repeatedly executed until NO in step S19 described later.
  • step S12 an arbitrary record among the records in which the flag 67 is “unprocessed” is set as a processing target record, and the device name 64, the address 65, etc. are obtained by referring to the processing target record (step S12), using these, the corresponding record in the shared memory 45 is searched and its data is acquired (step S13). That is, for example, a record whose device name 52 and address 53 are the same as the device name 64 and address 65 is the corresponding record. Then, the data 54 and error information 55 of the corresponding record are acquired as memory information 102 (step S13).
  • the memory information 102 includes data 81 and error information 82 shown in FIG. 9C, which are the acquired data 54 and error information 55 described above. Based on the memory information 102, it is determined whether or not a specific error (communication error, memory read error, etc.) has occurred (step S14). This is determined by whether the error information 82 is “error” or “normal”. Naturally, if the error information 82 is “error”, it is determined that a specific error has occurred (step S14, YES), and the process proceeds to step S16. On the other hand, if the error information 82 is “normal”, it is determined that there is no specific error (step S14, NO), and the process proceeds to step S15.

  • step S14 when there is a specific error (step S14, YES), an item drawing process at the time of an error by this method using the information of the processing target record and the error display image data 47 is performed (steps S16 and S17).

  • step S17 a process of drawing the specific mark (!) At the coordinates determined in step S16 (for example, developing on the RAM 13) is performed (step S17). Before that, the item drawing process similar to step S15 may be performed, but this process may not be performed.
  • the graphic controller 15 displays the drawing data on the RAM 13 on the display. Therefore, in the processing example described above, a specific mark (! Is displayed in the upper right corner of the image of the item in which the specific error has occurred.

Abstract

Selon la présente invention, une unité (44) de traitement de communication lit des données provenant d'une zone de stockage prédéterminée affectée pour chaque élément dans une mémoire à l'intérieur d'un appareil (4) connecté et stocke celles-ci dans une mémoire partagée. À cet instant, en cas de défaillance de lecture de données associée à un élément arbitraire, des informations d'erreur associées à l'élément sont stockées dans la mémoire partagée. Une unité (43) de traitement d'élément, par rapport à l'élément pour lequel les informations d'erreur ont été stockées, affiche des données (47) d'image d'affichage d'erreur correspondant à l'image d'élément.
