<Parameter update method-1>
Next, a parameter value update method using the controller of this embodiment will be described. In the update method described below, it is assumed that the worker wants to update the set value (parameter value) of the parameter number “CNT25” and the worker remembers the term “sitting retry counter”. (See FIG. 6). The “seating retry counter” refers to the number of times that the workpiece transfer robot re-executes the workpiece mounting operation when the workpiece mounting state on the headstock chuck is not appropriate.

  The parameter value update method includes a keyword input process, a search target selection process, a keyword search process, a search result display process, and a parameter value update process.

  In the keyword input process, first, the operator touches the keyword search button 40 shown in FIG. Next, the computing unit 20 shown in FIG. 1 switches the screen 23 to the keyword input screen 23b shown in FIG. Subsequently, the operator inputs “sitting retry counter”, which is a term he / she remembers, into the input field 41 via the keyboard 24 shown in FIG.

  In the search target selection step, the operator selects a desired search target (device comment, parameter name, manual) from a plurality of search targets. Specifically, the worker inputs a check mark in the selection field 42 regarding these three search targets.

  In the keyword search process, first, the operator touches the search execution button 45. Next, the arithmetic unit 20 shown in FIG. 1 searches for data including the “seating retry counter” from the data in the storage unit 21 (however, device comments, parameter names, and data associated with the manual). And the calculating part 20 switches the screen 23 to the search result display screen 23d shown in FIG.

  In the search result display step, the arithmetic unit 20 shown in FIG. 1 displays “sitting retry counter” in the input field 41 shown in FIG. 3 in the keyword display field 46 as shown in FIG. Further, the calculation unit 20 lists data including a device comment, a parameter name, and a “seating retry counter” in the manual in the search result display field 47. The worker visually recognizes the data related to the parameter value that he / she wants to update, that is, the data on the first line, from the enumerated data.

  In the parameter update process, first, the operator touches the data on the first line in the data in the search result display field 47. Next, the computing unit 20 shown in FIG. 1 switches the screen 23 to the parameter display screen 23e shown in FIG. As shown in FIG. 6, the calculation unit 20 surrounds the “sitting retry counter” with a thick frame C and highlights it. Subsequently, the operator inputs a new parameter value (for example, 3) of the parameter number “CNT25” in the first line of the parameter value display field 50. 1 rewrites the parameter value of the parameter number “CNT25” from 2 (old value) to 3 (new value) in the program of the storage unit 21. In addition, the calculation unit 20 displays whether or not the parameter value is updated in the parameter value update column 51. Finally, the operator touches the close button 52. The calculation unit 20 illustrated in FIG. 1 ends the parameter value update method.

<Parameter update method-2>
Next, another parameter value updating method using the controller of this embodiment will be described. FIG. 7 shows a schematic diagram (part 2) of the keyword input screen. FIG. 8 shows a schematic diagram (part 2) of the search result display screen. FIG. 9 shows a schematic diagram (part 2) of the parameter display screen. In the update method shown below, it is assumed that the worker wants to update the set value (parameter value) of the parameter number “SVP012” and the worker remembers the number “300”. (See FIG. 9). Moreover, in the update method shown below, only a different part from said <parameter update method-the 1> is demonstrated.

  In the keyword input process, the operator inputs “300”, which is a number he / she remembers, into the input field 41 shown in FIG. 7 via the keyboard 24 shown in FIG. In the search target selection step, as shown in FIG. 7, the operator selects a desired search target (abnormal data, parameter value) from a plurality of search targets. In the keyword search step, the calculation unit 20 shown in FIG. 1 searches for data including “300” from the data in the storage unit 21 (however, abnormal data and data associated with parameter values). In the search result display step, the computing unit 20 shown in FIG. 1 displays “300” in the input field 41 shown in FIG. 7 in the keyword display field 46 as shown in FIG. In addition, the calculation unit 20 lists abnormal data and data including “300” in the parameter value in the search result display field 47. The worker visually recognizes the data related to the parameter value that he / she wants to update, that is, the data on the first line, from the enumerated data.

  In the parameter update process, the operator inputs a new parameter value (for example, 250) of the parameter number “SVP012” in the first line of the parameter value display field 50 as shown in FIG. Then, the arithmetic unit 20 shown in FIG. 1 rewrites the parameter value of the parameter number “SVP012” from 300 (old value) to 250 (new value) in the program of the storage unit 21.

<Effect>
Next, the effect of the controller of this embodiment is demonstrated. As shown in FIGS. 3 and 7, an input field 41 is displayed on the keyword input screen 23b. For this reason, as shown in FIGS. 5, 6, 8, and 9, the operator can easily reach a desired search result from the enormous amount of data stored in the storage unit 21.

  Further, as shown in FIGS. 3 and 7, a search target and selection column 42 is displayed on the keyword input screen 23b. For this reason, the operator can narrow down the search target in advance and then perform a keyword search for the search target. Therefore, it is possible to improve the efficiency of search work.

  Further, as shown in FIGS. 5 and 8, the data in the search result display field 47 of the search result display screen 23d can be selected in units of lines. When the operator touches any data in the search result display field 47, the calculation unit 20 shown in FIG. 1 changes the screen 23 from the search result display screen 23d shown in FIGS. 5 and 8 to the parameters shown in FIGS. Switch to the display screen 23e. For this reason, the operator can easily confirm whether or not the selected search result is a desired search result.

  Further, as shown in FIGS. 6 and 9, the keyword is highlighted and surrounded by a thick frame C on the parameter display screen 23e. For this reason, the operator can easily confirm whether or not the selected search result is a search result related to the keyword.
