[Problems to be Solved by the Invention] In the conventional numerical control device configured as described above, the parameters related to the MAP are either fixedly stored in the storage unit or set and stored by operating the input device of the numerical control device. If the parameters were registered in the department, the parameters could not be changed even if they needed to be changed, or the parameters were somehow changed by the operator's operation of the input device of the numerical control device. However, since the contents of the parameters are difficult to understand, there have been problems such as the operator not being able to easily change the parameters.

[0008] This invention was made to solve the above-mentioned problems, and it provides software that allows MAP-related parameters to be edited in advance on a personal computer.
The edited parameter table is registered in a storage medium such as a floppy disk, and necessary parameters are read from the parameter table registered in the storage medium by an operator's operation of an input device or by a reading instruction from a client such as a host computer. It is an object of the present invention to provide a numerical control device that can easily change parameters related to MAP by downloading the MAP to a MAP interface.

[0009] Furthermore, when a problem such as a failure occurs in the network and it becomes necessary to check the parameters related to the MAP of the device connected to the MAP main line, the conventional numerical control configured as described above is used. The only way to check the parameters of the device is to check them on each individual numerical control device, and there have been problems such as the inability to check them all at once on the client.

[0010] The present invention was made to solve the above-mentioned problems, and the client requests the numerical control device connected to the MAP main line to send parameters related to the MAP.
The parameters that initialized the interface are sent to the client, and the client can check the parameters related to the MAP of each numerical control device all at once, or the parameters specified by the client can be sent from the numerical control device side to the client, and the parameters of each numerical control device can be checked. The object of the present invention is to obtain a numerical control device that allows a client to check specific parameters of the control device all at once.

[0011]Also, there are three communication frequency bands used on the MAP main line, but when connecting a conventional numerical control device configured as described above to the MAP main line, it is necessary to know the frequency being used in advance.

It is necessary to set and connect a predetermined individual unique address, but when connecting a conventional numerical control device configured as described above to the MAP main line, it is necessary to set a predetermined individual address that does not overlap. If the same address as another device forming the ring is set, there are problems such as not being able to communicate with the client without entering the logical ring, and not being able to notify the operator of the cause.

[0016] This invention was made to solve the above-mentioned problems, and when a device with the same address is already connected to the MAP main line when connecting to the MAP main line, an alarm is displayed. Furthermore, the object is to obtain a numerical control device that can reinitialize with a predetermined specific MAC address or network address, enter the logical ring, notify the client of an abnormality, and display an alarm on the client side as well.

First, when software for editing parameters related to MAP is started on a personal computer, a screen as shown in FIG. 2 is displayed on the display device of the personal computer. Figure 2
203 is the MA when item #2 is hit with the mouse.
Displays the contents of the X RETRY LIMIT parameter. The operator sets parameters #1 to #8 using the data input section 204 on the screen (step S1
). Next, the operator operates the ESC key on the personal computer to display the file registration menu display 205 in FIG. 3, and selects the file name [A:M RETRY. PRM] and comment [transport retry count 6], and register the parameter table in the floppy disk 30 inserted into the personal computer (step S2). The operator performs step S
1 and step S2 to remove the floppy disk 3.
Register several types of parameter tables in 0.

Next, the operator inserts the floppy disk 30 in which the parameter table is registered into the floppy drive device 16 of the numerical control device, operates the input/output keys on the input device 3, and inputs the information of the parameter table into the input interface. 8 to the control means 6a. The control means 6a controls the output interface 9 according to the input information.
By sending a command to the display device 2 via the controller, the display screen of the display device 2 is switched to the data input screen 103 shown in FIG. 4 (step S3).

Next, when the operator operates the "floppy" menu 100 of the menu display key 105 in FIG. 4, the display screen of the display device 2 is displayed in FIG.

At the same time, the control means 6a instructs the floppy control section 18 to read into the storage section 5 a list of file names registered in the floppy disk 30.

The floppy control unit 18 checks format information such as the number of cylinders, the number of sectors in a cylinder, the sector size, and the file system of the floppy 30 according to instructions from the control means 6a, and determines the format that can be handled by the numerical control device 1. (Step S)
5). If the determination result is YES, proceed to step S6; NO
In this case, the process moves to step S13.

If the format can be handled by the numerical control device 1, the floppy control section 18 controls the floppy drive device 16, reads the file name list data from the floppy 30 via the floppy input/output interface 17, and stores it in the storage section 5. Register. Next, the control means 6a

Next, the control means 6a reads information from the MAP interface 11 and determines whether a communication path (connection) has been established with the client (step S10). If the result of this determination is YES, the process moves to step S11, and if the result is NO, the process moves to step S12.

[0054] When a connection is established with the client, the control means 6a uses the MAP interface 11
The communication terminal instructs the terminal to terminate communication. The MAP interface 11 cuts off the connection with the client (step S11) according to the instruction from the control means 6a, and performs termination processing. Thereafter, the control means 6a displays "M" on the message display section 109 of the display device 2 via the output interface 9.
"AP interface initialization in progress" is displayed, and at the same time, the parameters related to MAP registered in the storage unit 5 are read out and the MAP interface 11 is initialized again (step S12).

If it is determined in step S5 that the format is not one that can be handled by the numerical control device 1, an error message such as "File name cannot be read" is displayed on the message display section 109 as shown in FIG. Step S
13).
