Abstract

PROBLEM TO BE SOLVED: To facilitate version-up or a control program. SOLUTION: An external storage device stores the version code and parameter of a control program before version-up and when the version code and parameter are received from the external storage device (step S1), a controller compares the received version code with the version code of the control program stored in an internal ROM (steps S3 and S10). When both version codes are different, the received parameter is automatically changed for the control program of the internal ROM (steps S4-S16) so that version-up of the control program can be easily dealt with.

A control program is stored in the ROM 5b of the control device 5. This control program is for executing the automatic operation and the manual operation described above,
The ROM 5b stores a version code “3 (= latest version)” that specifies the version of the control program. The ROM 5b has been upgraded by replacing a board on which a ROM with version code "1" or "2" is mounted with another board.

An external storage device 30 made of a floppy disk or the like is detachably mounted on the operation panel 2. The external storage device 30 corresponds to a second storage means. The external storage device 30 stores any one of the parameter files in the left, middle, and right columns of FIG. I have. The parameter file on the left column is composed of parameters 1 to 5 necessary to execute the control program with the version code “1”, and the parameter file on the left column contains the version code “1” of the control program. Is given.

The parameter file in the middle row is composed of parameters 1 to 6 necessary for executing the control program of version code "2". The parameter file in the middle row contains the version code of the control program. “2” is given. The parameter file in the right column contains parameters 1 to 3 and parameters 5 to 6 necessary for executing the control program of version code “3”.
The version code “3” of the control program is assigned to the parameter file in the right column.

The parameter file and the version code of the external storage device 30 are previously output from the control device 5 to the external storage device 30 through the communication device 8 when the machining center 9 is operating, as shown in FIG.

As shown in FIG. 5, a parameter setting key 31 is mounted on the front of the operation panel 2. When the controller 5 detects the operation of the parameter setting key 31,
A parameter setting screen is displayed on CRT3. FIG. 3 shows a parameter setting screen. In the left column, "maximum cutting movement speed", "maximum manual movement speed",... "Position loop gain" are parameters, and each number in the right column is a parameter setting value. is there. When the keyboard 4 is operated in this state, the control device 5 rewrites the parameter set values according to the operation contents of the keyboard 4.

FIG. 1 is a flow chart showing the contents stored in the ROM 5b. The control device 5 processes the parameter file and the version code transmitted from the external storage device 30 based on the flow chart of FIG. The file is expanded on the RAM 5b. Hereinafter, the flowchart of FIG. 1 will be described in detail.

When the control device 5 finishes receiving the parameter file transmitted from the external storage device 30 in step S1, the control device 5 proceeds to step S2, reads the version code assigned to the parameter file, and then executes step S1.
3 to determine whether the version code is “1”. For example, when the version code is “1”, the process proceeds to step S4.

The parameter file to which the version code “1” is added is, as shown in the left column of FIG.
It is composed of parameters 1 to 5. On the contrary,
To execute the control program of the version code “3” stored in the ROM 5b of the control device 5, a parameter file including parameters 1 to 3 and parameters 5 to 6 is required. Therefore, when the control device 5 proceeds to step S4, the control device 5 writes the first data of the parameter file received from the external storage device 30 as the parameter 1 into the RAM 5c, and then proceeds to step S5.

At step S5, the control device 5 writes the second data of the parameter file received from the external storage device 30 into the RAM 5c as the parameter 2, and then proceeds to step S6. Then, the third data of the parameter file received from the external storage device 30 is written into the RAM 5c as the parameter 3, and the process proceeds to step S
7, the fourth data of the parameter file received from the external storage device 30 is skipped (deleted), and the process proceeds to step S8.

At step S8, the control device 5 writes the fifth data of the parameter file received from the external storage device 30 as the parameter 5 into the RAM 5c, and then proceeds to step S9. Then, by writing the default value as the parameter 6 to the RAM 5c (addition of the parameter), the parameter file received from the external storage device 30 is changed for the latest control program of the version code "3", and the process is terminated. . Note that the default value refers to a value that does not cause harm in executing the control program, and is specifically an initial value such as “0”.

If the control device 5 determines in step S3 that the parameter file received from the external storage device 30 is not version code "1", the process proceeds to step S10, and determines whether the version code is "2". For example, when the version code is “2”, the process proceeds to step S11.

The parameter file of the version code "2" is composed of parameters 1 to 6 as shown in the middle row of FIG. Accordingly, when the control device 5 proceeds to step S11, the control device 5 stores the first data of the parameter file received from the external storage device 30 in the parameter 1
After that, the process proceeds to step S12. Then, the second data of the parameter file received from the external storage device 30
After writing to M5c, the process proceeds to step S13.

At step S13, the control device 5 writes the third data of the parameter file received from the external storage device 30 into the RAM 5c as the parameter 3, and proceeds to step S14. Then, the fourth data of the parameter file received from the external storage device 30 is skipped, and the process proceeds to step S15.

At step S15, the control device 5 writes the fifth data of the parameter file received from the external storage device 30 into the RAM 5c as the parameter 5, and proceeds to step S16. Then, as the sixth data of the parameter file received from the external storage device 30 is written to the RAM 5c as the parameter 6, the parameter file received from the external storage device 30 is changed to the latest control program stored in the ROM 5b. Then, the process ends.

When detecting that the parameter file received from the external storage device 30 is the version code "3", the control device 5 determines "NO" in step S10 and proceeds to steps S17 to S21. Then, 1 to 3 of the parameter files received from the external storage device 30
The fifth data is written into the RAM 5c as parameters 1 to 3 and 5 to 6, and the process ends.

According to the above embodiment, the version code stored in the external storage device 30 is compared with the version code stored in the ROM 5b, and if they are different, the version code stored in the external storage device 30 is stored. RO parameter
It is determined that the control program cannot be used for the control program stored in the M5b, and the parameters stored in the external storage device 30 are changed for the control program stored in the ROM 5b. For this reason, the user operates the keyboard 4 to input all the parameters, or stores the data stored in the external storage device 30 in the RO.
Since there is no need to change the control program for the M5b, it is possible to easily cope with an upgrade of the control program.

An external storage device 30 is detachably mounted on the control device 5. Therefore, the parameters and the version code before the version upgrade can be stored in the external storage device 30. Unlike the case where the parameters and the version code before the version upgrade are stored in the internal RAM 5c, the Even when the internal ROM 5b and the internal RAM 5c are exchanged together (when the ROM 5b and the RAM 5c are mounted on the same board), the parameters can be changed for the control program of the internal ROM 5b.

Further, since the parameters are added or deleted from the parameter file from the external storage device 30, it is possible to cope with the increase or decrease of the parameters. In addition, a default value was set for the parameter when the parameter was added. This eliminates the need to operate the keyboard 4 to input parameters when adding parameters. At the same time, since the machining center 9 is controlled based on the default value, for example, the following excessive operations of the machining center 9 are prevented.

In the case of the high-speed moving maximum speed shown in FIG. 3, the limit speed of the motor is 5000 mm / min. Therefore, 8
If the value of 000 mm / min is set as a parameter, the motor may be broken when the machining center 9 is operated. In the case of the fast-forward time constant shown in FIG. 3, the limit value of the machining center 9 is 160. Therefore, if a value smaller than 160 is set as a parameter, the machining center 9 may be broken.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described. The external storage device 30 stores one of the parameter files in the left, middle, and right columns of FIG.

The parameter file in the left column includes a non-common file composed of parameters 1 to 5 and a parameter 1
The common file is composed of the common files 1 to 18. The non-common file is assigned a version code “1”, and the common file is assigned a version code “A”.

The parameter file in the middle row includes a non-common file composed of parameters 1 to 6 and a parameter 1

The parameter file on the right column is composed of a non-common file composed of parameters 1 to 3 and parameters 5 to 6 and a common file composed of parameters 11 to 18. Version code “3” is assigned, and version code “A” is assigned to the common file.

The ROM 5b of the control device 5 stores information for inhibiting the change of the common file of the version code "A". The control device 5 reads the parameter file from the external storage device 30 in step S1 in FIG. Upon reception, the process proceeds to step S2. After reading the two version codes assigned to the parameter file, the process proceeds to step S22.

At step S22, the control device 5 expands the first to eighth data of the common file of the version code "A" received from the external storage device 30 into the RAM 5c without changing them as parameters 11 to 18. After that, the process moves to step S3. Then, the version code of the non-common file received from the external storage device 30 is compared with the version code “3” of the ROM 5b.

If the controller 5 determines in step S3 that the two version codes are different, the non-common file is stored in the RAM for the control program of version code "3".
5c, a parameter file including a common file and a non-common file is set. FIG. 11B
Shows how the parameter file is changed.

If the version code from the external storage device 30 is "1", the parameter 6 is added and the parameter 4 is deleted from the parameter file from the external storage device 30, and the version code "3" is set. Is set. Also, the external storage device 30
If the version code from the external storage device 30 is “2”, the parameter 4
Is deleted, and a parameter file of version code “3” is set. The parameter file and the version code of the external storage device 30 are input in advance from the control device 5 to the external storage device 30 through the communication device 8 when the machining center 9 is operated.

According to the above embodiment, the parameters of the external storage device 30 are classified into those corresponding to the control program in the ROM 5b and those not corresponding to the control program in the ROM 5b. Since only those which do not correspond to the control program of the ROM 5b are changed, the processing speed is increased.
