In the conventional numerical controller configured as described above, the parameters relating to the MAP are fixedly stored in the storage unit or set and stored by operating the input device of the numerical controller. , But this parameter may need to be changed. For example, there are cases where it is desired to change the MAC layer parameters such as the maximum number of retries when transmission fails or the token holding time of the own device. However, it may not be possible to change these parameters at the factory floor. In some cases, the parameter can be changed by the operator's operation of the input device of the numerical controller, but since the content of the parameter is difficult,

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a numerical control device capable of detecting a communication frequency band used in a MAP trunk when power is turned on. is there.

When a MAP network is constructed, the level of the network must be adjusted because a coaxial cable is used for the MAP trunk. In the conventional numerical control device configured as described above, the operator changes the parameters and the like for each numerical control device, adjusts the output level of the modem of the numerical control device connected to the MAP main line, and There were problems such as level adjustment.

When connecting the device to the MAP main line,
Although it is necessary to set and connect a predetermined individual non-overlapping address, when connecting the conventional numerical controller configured as described above to the MAP main line, it is necessary to set a logical address already connected to the MAP main line. If the same address as another device constituting the ring is set, there is a problem that communication cannot be performed with the client without entering the logical ring, and the cause cannot be notified to the operator.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. When a device having the same address is already connected to a MAP main line when connecting to a MAP main line, an alarm is displayed. It is another object of the present invention to provide a numerical controller capable of reinitializing a predetermined specific MAC address or network address, entering the logical ring, notifying a client of an abnormality, and displaying an alarm on the client side. It is assumed that.

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

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 an instruction from the control means 6a, and the format that the numerical controller 1 can handle. Is determined (step S
5). If the determination is YES, the process proceeds to step S6, and NO
In the case of, the process moves to step S13.

If the format can be handled by the numerical controller 1, the floppy controller 18 controls the floppy drive 16 to read the file name list data from the floppy 30 via the floppy input / output interface 17 and store it in the storage unit 5. Register with. Next, the control means 6a
The file name list data registered in the storage unit 5 is displayed on the display device 2 via the output interface 9 as a file name list 98 as shown in FIG. 5 (step S).

Is displayed, and at the same time, a file input is instructed to the parameter table selection input instructing means 20. The parameter selection input instructing means 20 instructs the floppy control unit 18 to read the specified file by a command from the control means 6a. When reading the file specified by the operator from the floppy 30 via the floppy drive device 16, the floppy control unit 18 registers the specified file in the storage unit 5 in the same operation as when the file name list is registered in the storage unit 5. (Step S9).

Next, the control means 6a reads information from the MAP interface 11 and determines whether or not a communication path (connection) has been established with the client (step S10). When the result of the determination is YES, the process proceeds to step S11, and when the result is NO, the process proceeds to step S12.

When a connection has been established with the client, the control means 6a
To the communication end. The MAP interface 11 disconnects the connection with the client in response to an instruction from the control unit 6a (step S11), and performs a termination process. Thereafter, the control unit 6a displays “M” on the message display unit 109 of the display device 2 via the output interface 9.
At the same time as "AP interface initialization in progress" is displayed, the MAP parameters 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 a format that can be handled by the numerical controller 1, an error message such as "file name cannot be read" is displayed on the message display unit 109 as shown in FIG. Step S

This corresponds to each item (MAC of FIGS. 2 and 3)
In the example of the layer parameter, variable data of up to three levels can be set for parameters for each of eight items, transmission frequency band / reception frequency band, communication frequency band detection priority, modem output level, and the like. Three parameter tables in which the parameters of the items are combined and grouped are provided in advance (to facilitate batch change of MAP-related parameters at the factory site). However, the present invention is not limited to this. For example, data of the number set for each parameter of each item is stored, and the parameter of the data value selected by the selection signal for each parameter of each item is stored. The change may be made by taking out the change. This method requires only a short time in the case of a partial parameter change, and requires less memory than a table memory.
