Thus, by storing the position stored for each data group and the version at the time of creation, it can be determined whether or not the data group can be read out.

  As shown in FIG. 8 (b), the setting file created in the new version 2.0 is similar to the setting file created in version 1.0, and the file size, file format version, readable version, and block information with offset. Number, block information with offset, and a plurality of data groups. Since the number of storage location data is two, block A and block B, the number of offset block information is “2”. And the storage position of each block is memorize | stored as block information with an offset.

  The data group stored in the block A in FIG. 8B is a data group whose file format is version 1.0. Therefore, even version 2.0 can be read. The storage position data of the block A is stored as “block information with offset A”. Thus, by storing the position stored for each data group and the version at the time of creation, it can be determined whether or not the data group can be read out.

  In other words, the setting file according to the present embodiment is stored in the image sensor other than the version (first version data) of the computer program (software) installed in the created image processing sensor when the setting file is created. Since the version (second version data) that can be read is stored, it is possible to determine whether there is an additional function, an extended function, or the like from the version difference, and to read the data group from the setting file It can be determined whether or not it is possible.

  FIG. 9 is a view showing an example of screen transition when creating a setting file according to the embodiment of the present invention. When the “USB memory” button 50 shown in FIG. 5A or 5B is selected, a setting file operation screen shown in FIG. 9A is displayed first. When the “collective backup” button 91 on the setting file operation screen is selected, a setting file designation screen shown in FIG. 9B is displayed.

  When the input of the setting file name to be created is accepted in the setting file name setting area 92 of the setting file designation screen and the “execute” button 93 is selected, a writing screen 94 shown in FIG. 9C is displayed. The When the writing of the setting file is completed, a completion screen shown in FIG. 9D is displayed. When the “OK” button 95 is selected, the screen returns to the “inspection mode” screen shown in FIG. 5A or the “setting mode” screen shown in FIG.

  FIG. 10 is a functional block diagram of the setting file reading device 10 of the image processing sensor according to the embodiment of the present invention. In FIG. 10, the setting file reading device 10 includes an imaging device 1 and a display device 2.

  A setting file designation receiving unit 901 of the display device 2 receives designation of a setting file to be read. Information regarding the setting file that has received the designation is transmitted to the imaging apparatus 1. In the present embodiment, the designation is accepted from the user on the touch panel 21. However, the designation may be accepted by a signal from the PLC, for example. Further, when viewed from the imaging device 1, the setting file designation is accepted based on a signal sent from the display device 2. That is, the setting file designation receiving unit 901 may be provided on the imaging device 1 side.

  The data reading unit 902 of the imaging device 1 reads the first version data, the second version data, and the storage position data from the setting file that has been designated by the display device 2. The position indicated by the storage position data may be a physical position or a logical position. For example, when the data group is stored in units of blocks, the data group can be configured by the offset amount of the start position of the block and the size of the block.

  In this case, it is possible to determine whether or not the data group can be read correctly by checking the block size. The size confirmation unit 903 confirms whether or not the block size of the data group matches the block size of the storage location data read by the data reading unit 902. If they do not match, the data group cannot be read correctly.

  The version determination unit 904 determines whether the version of the read second version data is older than the version of the computer program installed in the electronic device to be read. When the version determining unit 904 determines that the version to be read is the same as or the second version data is older, the setting file reading unit 905 determines the first data from the setting file that has received the designation based on the storage location data. Read a group.

  When the version determination unit 904 determines that the version that is the same as the read version or the version indicated by the read second version data is older, the read determination unit 906 reads the version indicated by the read first version data. It is determined whether or not the version is possible. If it is determined that the version is readable, the second data group is read from the setting file that has received the designation.

  If the read determination unit 906 determines that the version is not readable, the read determination unit 906 transmits an instruction to the display device 2 to output a message indicating that the setting file cannot be read. When the message output unit 907 receives a message output instruction from the imaging device 1, the message output unit 907 displays a message indicating that the setting file cannot be read out as an error message on the display device 2.

  FIG. 11 is a flowchart showing the procedure of the file reading process of setting file reading apparatus 10 according to the embodiment of the present invention. In FIG. 11, the main control unit of the display device 2 accepts designation of a setting file to be read (step S1101). Information regarding the setting file that has received the designation is transmitted to the imaging apparatus 1.

  The DSP 132 of the imaging apparatus 1 reads the first version data, the second version data, and the storage position data from the setting file that has been designated by the display device 2 (step S1102), and is specified by the read storage position data. A data group stored at the position is read (step S1103). The position indicated by the storage position data may be a physical position or a logical position. For example, when a data group is stored in units of blocks, the data group can be configured with a block offset amount and a block size.

  In this case, it is possible to determine whether or not the data group can be read correctly by checking the block size. The DSP 132 determines whether or not the block size of the data group matches the block size of the read storage position data (step S1104). If the DSP 132 determines that the sizes do not match (step S1104: NO), the DSP 132 determines that the data group has not been correctly read and instructs the display device 2 to output a read error message. Transmit (step S1105). The main control unit of the display device 2 that has received the instruction to output the read error message displays and outputs the read error message (step S1106).

  If the DSP 132 determines that the sizes match (step S1104: YES), the DSP 132 determines that the data group has been read correctly, and the read version of the first version data is read out. It is determined whether or not the version of the first version data is the same as or older than the version of the computer program (software) installed in step S1107.

  When the DSP 132 determines that the version to be read is the same as the version to be read or the version of the first version data is older (step S1107: YES), the DSP 132 reads the data group by a method similar to the conventional method (step S1108). When the DSP 132 determines that the version of the first version data is newer (step S1107: NO), the DSP 132 compares the read version with the version of the second version data (step S1109).

  When the DSP 132 determines that the version of the second version data is older (step S1109: older), the DSP 132 reads the first data group (step S1110). When the DSP 132 determines that the version of the second version data is the same (step S1109: the same), the DSP 132 reads the first data group and the second data group (step S1111).

  When the DSP 132 determines that the version of the second version data is newer (step S1109: newer), the DSP 132 instructs the display device 2 to output a read error message indicating that the setting file cannot be read. Transmitting (step S1112), the main control unit of the display device 2 displays and outputs a read error message (step S1113).

  Note that the functional block diagram shown in FIG. 10 and the flowchart shown in FIG. 11 are examples, and other configurations may be used. For example, in the functional block diagram illustrated in FIG. 10, the version determination unit 904 and the read determination unit 906 are provided on the imaging device 1 side. However, the present invention is not particularly limited to this. For example, the version determination unit 904 and the read determination unit 906 may be provided on the display device 2 side.

  When the version determination unit 904 and the read determination unit 906 are provided on the display device 2 side, specifically, information related to the version of the computer program (software) installed in the imaging device 1 is transmitted to the display device 2 in advance. The data is stored in the memory by the display device 2. When the designation of the setting file is received from the user, the control unit (CPU or the like) provided in the display device 2 reads the first version data, the second version data, the storage position data, and the data group. Do. Then, it is determined whether or not the sizes of the blocks of the data group match. If it is determined that they do not match, an output instruction and display output of a read error message are performed (steps S1102 to S1106 in FIG. 11). Process corresponding to the process of).

  On the other hand, if it is determined that they match, the control unit of the display device 2 has the same version of the read first version data as the version of the installed computer program (software) or the first version data. Determine whether the version of the version data is older or not, and if it is determined that the version of the first version data is the same as the installed version or older, read the data group in the same way as before (Processing corresponding to the processing of step S1107 to step S1108 in FIG. 11), the first data group is transmitted to the imaging apparatus 1. On the other hand, if it is determined that the version of the first version data is newer, the version of the installed computer program (software) is compared with the version of the second version data (step S1109 in FIG. 11). Process corresponding to the process of).

  When it is determined that the version of the second version data is older, the first data group is read out and transmitted to the imaging device 1, and when it is determined that the version is the same as the version of the second version data. The first data group and the second data group are read out and transmitted to the imaging device 1, and when it is determined that the version of the second version data is newer, an output display and display output of a read error message are performed. Performed (a process corresponding to the process of steps S1110 to S1112 in FIG. 11).

  FIG. 12 is a view showing an example of setting data in the setting file of the image processing sensor according to the embodiment of the present invention. In order to simplify the explanation, the version is assumed to be 1.0, 2.0, and 3.0, the trigger conditions are only representative trigger cycles, and the other set values are only ON / OFF.

  12A shows the settable range of the oldest version 1.0, FIG. 12B shows the settable range of the next oldest version 2.0, and FIG. 12C shows the latest set of version 3.0. Each settable range is shown. As the version is newer, the settable range of the trigger period becomes wider, and the block B does not exist in the first version 1.0.

  FIG. 13 is a flowchart showing a processing procedure for determining a readable version of the setting file of the DSP 132 of the imaging apparatus 1 of the image processing sensor according to the embodiment of the present invention. FIG. 13 illustrates a case where the version of the computer program installed in the created image processing sensor is the latest version 3.0 when the setting file to be read is created. For convenience, the version of “version X.0” is indicated by “X”, and the blocks A, B,... Are indicated by “1”, “2”,.

  In FIG. 13, the DSP 132 initializes an argument i to “1” and an argument j to “M (latest version number)” (step S1301). Here, the argument i indicates a block, and the argument j indicates a version. In the example of FIG. 12, since the block is two blocks A and B, the argument i is “1” and “2”, and the latest version is 3.0, so the argument j is “3” and “2”. , '1'.

  The DSP 132 starts checking block i (step S1302). First, the DSP 132 determines whether there is an additional setting from the immediately previous version (j−1) and whether the additional setting is other than the initial value (step S1303). When the DSP 132 determines that there is an additional setting and the additional setting is other than the initial value (step S1303: YES), the DSP 132 determines that the version older than the version j cannot be read and can read the version j. Is output as a new version (step S1304).

  When the DSP 132 determines that there is no additional setting or that there is an additional setting and the additional setting is an initial value (step S1303: NO), the DSP 132 sets the setting data in the immediately preceding version (j-1). It is determined whether it is within (step S1305). When the DSP 132 determines that the version (j-1) is not within the settable range (step S1305: NO), the DSP 132 determines that the version older than the version j cannot be read and can read the version j. The version is output (step S1306).

  When the DSP 132 determines that the version (j-1) is within the settable range (step S1305: YES), the DSP 132 determines whether the last block is checked (step S1307). ). When the DSP 132 determines that the block is not the last block (step S1307: NO), the DSP 132 increments i by “1” (step S1308), returns the process to step S1302, and repeats the above-described process.

  When the DSP 132 determines that it is the last block (step S1307: YES), the DSP 132 determines whether j is 2 or less (step S1309). When the DSP 132 determines that j is greater than 2 (step S1309: NO), the DSP 132 decrements j to “1”, initializes i to “1” (step S1310), and returns the process to step S1302. The above process is repeated.

  When the DSP 132 determines that j is 2 or less (step S1309: YES), the DSP 132 outputs version 1 as a readable version (step S1311).

  Considering the example of FIG. 12, first, the block A is checked, and since there is no additional setting from the previous version 2 and all the set values are within the settable range of the version 2, the block B is checked. Proceed with Also for block B, since there is no additional setting from version 2, which is the previous version, and all the set values are within the settable range of version 2, j is decremented to ‘2’, and the process returns to step S1302.

  For block A, since there is no additional setting from version 1, which is the immediately preceding version, and all the setting values are within the settable range of version 1, the process proceeds to checking block B. The block B does not exist in the version 1 that is the immediately preceding version, but since all the setting values of the block B are initial values, the version 1 is output as a readable version.

  Note that the version of the first version data may be checked after reading the first data group. FIG. 14 is a flowchart showing another procedure of the file reading process of setting file reading apparatus 10 according to the embodiment of the present invention. In FIG. 14, the main control unit of the display device 2 accepts designation of a setting file to be read (step S1401). Information regarding the setting file that has received the designation is transmitted to the imaging apparatus 1.

  The DSP 132 of the imaging apparatus 1 reads the first version data, the second version data, and the storage position data from the setting file that has been designated by the display device 2 (step S1402), and is specified by the read storage position data. The data group stored at the position is read (step S1403). The position indicated by the storage position data may be a physical position or a logical position. For example, when a data group is stored in units of blocks, the data group can be configured with a block offset amount and a block size.

  In this case, it is possible to determine whether or not the data group can be read correctly by checking the block size. The DSP 132 determines whether or not the block size of the data group matches the block size of the read storage position data (step S1404). If the DSP 132 determines that the sizes do not match (step S1404: NO), the DSP 132 determines that the data group has not been correctly read and instructs the display device 2 to output a read error message. Transmit (step S1405). The main control unit of the display device 2 that has received the instruction to output the read error message displays and outputs the read error message (step S1406).

  When the DSP 132 determines that the sizes match (step S1404: YES), the DSP 132 determines that the data group has been correctly read, and the version of the read second version data is read out. It is determined whether the version of the version data of the computer program (software) installed in the same or the second version data is older (step S1407).

  When the DSP 132 determines that the version to be read is the same as the version to be read or the version of the second version data is older (step S1407: YES), the DSP 132 reads the first data group (step S1408), and the first version data It is determined whether or not the version indicated by is a readable version (step S1409). When the DSP 132 determines that the version is readable (step S1409: YES), the DSP 132 reads the second data group (step S1410).

  When the DSP 132 determines that the second version data is newer (step S1407: NO) and when the DSP 132 determines that the version data cannot be read (step S1409: NO), the DSP 132 reads the setting file. An instruction to output a reading error message indicating that the reading cannot be performed is transmitted to the display device 2 (step S1411), and the main control unit of the display device 2 displays and outputs a reading error message (step S1412).

  As described above, according to the present embodiment, when the setting file is created, the version of the computer program (software) installed in the created electronic device is stored as the first version data. Since the version that can be read is stored as the second version data, it can be determined whether there is an additional function, an extended function, or the like based on the version difference, and the data group can be read from the setting file. It can be determined whether or not. Therefore, when multiple electronic devices are operated under the same operating conditions, since there is no additional setting data, the setting data is within the settable range of all versions. Even if created, the setting file can be read out in all electronic devices, and it is possible to avoid the occurrence of a malfunction such as a malfunction due to a difference in version.

  The present invention is not limited to the above-described embodiments, and various changes and improvements can be made within the scope of the present invention. For example, the present invention is not limited to the case where an image processing sensor is used as an electronic device, and the same effect can be expected as long as the electronic device is operated under the same operating conditions in the production line. Moreover, in the said Example, although the imaging device 1 and the display apparatus 2 became a different body, the image processing sensor with which both were united may be sufficient. Further, whether or not the setting file can be read can be determined by the imaging device 1 or the display device 2. For example, after determining whether or not reading is possible on the display device 2, only a readable data group may be transmitted from the display device 2 to the imaging device 1.
