This is provided to ignore even if there is an alarm at 4V, and wait for a certain time. Step 207 checks whether a current exceeding the rated current flows to the load and the voltage is not lower than the rated value. If the voltage has become insufficient, the process proceeds to step 216. In step 208, the stabilized power supply 1
In step 1, after the start-up is completed, it is checked whether the battery voltage is normal. If the battery voltage is insufficient, the battery abnormality signal is turned on. Step 211 and subsequent steps are a routine after normal startup.

At step 211, it is checked whether the AC input is undervoltage or overvoltage. If the voltage is undervoltage or overvoltage, the AVR abnormality signal is turned on at step 212.

In step 215, it is checked whether the 24V voltage is insufficient or overvoltage. If the 24V voltage is insufficient or overvoltage, 24V · O
The N signal is turned off, and the 24V output is turned off. In step 217, it is checked whether the AC input is turned off or the OFF switch is pressed. If the AC input is turned off or the OFF switch is pressed, in step 218, the power is turned on after the instantaneous power failure allowable time.
/ OFF signal is turned off and the switching unit 153 is turned off.
At the same time as F, the AC input disconnection signal is turned on to interrupt the CPU 101. CPU 101 turns off AC input signal
Then, processing such as saving the necessary memory contents is performed before the DC output completely disappears. In step 219, the CPU 101 of the control unit 10 waits for the elapse of the processing time when the power is turned off, such as saving the contents of the memory, turns on the memory protection signal, and switches the power supply to the memory to the battery.

The CRTC 213 constantly scans the text RAM 214A, and the CRTC 213 displays the text RAM 2 corresponding to the position where the character on the display screen 201 should be displayed.
When the address of 14A is selected, character information written at that address is output and the CRT I / F 216
Is input to The CRT / I / F 216 converts this input signal into a serial video signal having a dot clock frequency conforming to the specification of the display screen 201 and outputs it to the display screen 201. In this way, of the output data of the control unit 10, display data to be displayed on the display screen 201 is displayed on the display screen 201.

On the other hand, data to be output to the lamp 207 turns on the lamp 207 of the machine operation board 205 via the key I / F lamp output 217. When an operator operates a key or a mechanical switch of the NC operation board or the machine operation board 205, this signal is read out to the MPU 210 via the key I / F / lamp output 217 and is read out by the communication I / F.
The signal is output to the circuit 218 and transmitted to the control unit 10 via the signal switching unit 57.

When the signal switching unit 57 is set on the NC1 side, the operator operates the sequence controller operating unit 2
Even if one key is operated, the data is not transmitted to the sequence control device 56, the data transmitted from the sequence control device 56 to the composite operation board 22 is ignored, and is not displayed on the display screen 201, and the sequence control device operation section 21 is not displayed. Lamp is not turned on. The same applies to the case where the signal switching unit 57 is set on the sequence controller 56 side.

[0049] Upon receiving the erase command in the interrupt waiting state, the identification whether a command for their in step 13. This identification is performed by the axis number selection switch 31 shown in FIG.
Whether the axis number set in 4 matches the received axis number shown in FIG. 5, or the drive type set in the drive type setting switch 315 matches the received drive type shown in FIG. Find out what. For axis 1, select axis number
Switch = 8 and received data is axis number = 1
Interprets this command as a command for itself
Further, when the drive type setting switch = 0, the reception data
Since the data is also a servo drive,
It is understood that it is. If the axis number and the drive unit type match, the process proceeds to step 14 as a command to be executed. At step 14, the flash memory 304A is erased. When the erasure is completed, the control unit 10 notifies the completion of the erasure.
Send to A. The control unit 10A receives the completion of the erasure, and proceeds to step 5 if the erasure of all axes is completed in step 4. The same applies to the second and third axes.
Description is omitted.

In step 5, a write / verify command is transmitted to the first axis driving device . The write / verify command includes an axis number, a drive type, a command code, a start address, a data length, and a drive S / W as shown in FIG. Since the driving device of the first axis is a servo driving device,
The contents of the command are as follows. Axis number ...... 1 drive type ...... Servo drive command code ...... Write / verification command start address ...... Start address data length of address assigned to flash memory 304A ...... Flash memory capacity drive Device S / W ... Drive device S / W # 1 (servo drive device) Following transmission to the drive device of the first axis , writing to the second axis.
Send a collation command. The contents of the command are
It is the same as the first axis except that it becomes 2. Second axis drive
Sends a write / verify command to axis 3 following transmission to
I do. The contents of the command are as follows. Axis number ..... 3 drive types ..... Spindle drive command code ..... Write / verify command start address ..... Start address data length of addresses allocated to flash memory 304A ..... Capacity drive of flash memory Device S / W... Drive device S / W # 2 (spindle drive device) The drive device 30A uses this reception interrupt to determine in step 15 whether the command is a command to be executed in the same manner as in step 13. I do. If it is a command to be executed, the process proceeds to step 16. In step 16, the driving device S / W is stored in RAM3.
Store at 03. In step 17, writing is performed to the flash memory 304A by the number of bytes specified by the data length from the head address in FIG. 5, and then it is checked whether the writing was successful. When the writing and collation are completed, a message indicating the completion of the writing and collation is transmitted to the control unit 10A.

The control unit 10A receives the completion of the writing / collation, and when the writing / collation of all the axes is completed in step 6, the operation ends. It should be noted that the distinction between “ROM cutting in progress”, “normal termination”, and “error termination” may be displayed by attaching an appropriate LED (not shown) to the control unit 10A or the driving device 30A. Although the case of “error end” is not described in the flowchart of FIG. 3 for convenience of explanation, a flag that can distinguish “normal end” and “error end” is included in the completion signal from the driving device 30A to the control unit 10A. Just attach it. Finally, the power is turned off and the servo memory 113 is turned off.
Is removed, and the system memory 103A is attached to the control unit 10A and the selection number switch 314 on the drive device 30A side is set to the normal operation mode, and the power is turned on again, thereby starting the normal operation.

In this embodiment, the axis selection number switch 314 of the drive unit 30A is set differently from that in the normal operation. However, the command shown in FIG.
If the data structure is configured so that it can be distinguished from the transmitted data, it is not necessary to distinguish between the normal operation and the driving device S / W writing. In the above-described embodiment, for convenience of explanation, the flowchart for batch transmission of the driving devices S / W is used. However, when the capacity of the RAM 303 is insufficient, the command of FIG. Therefore, it is sufficient to transmit the data in appropriate blocks. In this case, steps 5 and 6 are repeated.

The driving device S /
When W is on, the axis number selection switch is set to 0 to 7, and when the driving device S / W is updated, the axis number selection switch is set to 8 to F. In FIG. 8, an AC power supply (not shown)
Is inserted, the control unit 10B and the driving device 30A
Is supplied to the CPU 101 of the control unit 10B.
MPU 1011 in the device and MPU 301 in the drive device 30A
Is reset, the control unit 10B and the driving device 30A
Starts working. First, the operation of the control unit 10B will be described. The system is operated in step 1A. And
The operator displays a drive device S / W program screen by key operation using the menu key 204 of the operation board 20. In step 2A, the operator starts after selecting a menu by operating the keys on the operation board 20. This method will be described with reference to FIG. In the upper half of the display screen 201, a selectable S / W menu and key correspondence table are displayed. In the lower half, a menu corresponding to the axis and a programming status of the driving device S / W can be displayed. The mark indicates the current cursor position, and the operator is displayed on the display screen 201.
The upper half of, in accordance with the correspondence table of the menu and the key of S / W,
Press the key corresponding to the S / W menu. Then , a numeral or alphabet is put in the mark (2), and the cursor moves to the axis 2. When the operator repeats such a menu selection operation to set the final axis (axis n), the menu key 20
The user presses the key corresponding to the start of the inner screen display 201 of No. 4. Then, the transmission in the system operation to the drive device 30A is stopped, and the process proceeds to step 3 to shift to the actual programming operation.

In step 3, an erase command is transmitted to the first axis servo. The command is configured as shown in FIG. 5, but in the case of an erase command, the flash memory 304A
, The head address, the data length, and the area of the driving device S / W are blank. Following transmission to the first axis servo, an erasure command is transmitted to the second to n-th axes (final axes). In step 11A, the drive device 30A side is in an operation state in the drive device S / W when the axis selection number switch 314 is 0 to 7, and communicates with the control unit 10B at regular time intervals, and the axis selection number is 8 to In the case of F, a standby state is set as in the first embodiment. In step 12, even when the axis number selection switch 314 is 0 to 7, the reception interrupt can be accepted.
You . When an erase command is received in this interrupt waiting state, it is determined in step 13 whether the command is a command to be executed.
This identification is performed by checking whether the axis number set by the axis number selection switch 314 in FIG. 2 matches the received axis number shown in FIG. 5, and the drive type set by the drive type setting switch 315. It is checked whether the received drive device types shown in FIG. If the axis number and the drive unit type match, the process proceeds to step 14 as a command to be executed. At step 14, the flash memory 304A is erased. When the erasure is completed, the control unit 1 informs that the erasure is completed.
0B. The control unit 10B performs step 4A
Then, the completion of the erasure is received, and a symbol of the completion, for example, a black mark is displayed at the position of the circle corresponding to the position of the axis corresponding to the completion of the erasure on the display screen 201. When erasure of all axes is completed, the process proceeds to step 5.

At step 5, a write / verify command is transmitted to the first axis servo. Write / verify commands include axis number, drive type, command code, start address, data length,
It is composed of a driving device S / W. Following transmission to the first axis servo, a write / verify command is transmitted to the second to n-th axes (final axes). The drive device 30A identifies whether the command is a command to be executed in step 15 at step 15 in the same manner as in step 13, and if the command is a command to be executed, proceeds to step 16. In step 16, the driving device S
/ W is stored in the RAM 303. FIG.
Is written to the flash memory 304A by the number of bytes specified by the data length from the start address of the flash memory 304A, and then it is verified whether or not the data was written correctly. When the writing and the collation are completed, a notification that the writing and the collation are completed is transmitted to the control unit 10B. The control unit 10B receives the completion of the writing / collation in step 6A, and displays a completion sign, for example , a black mark at the position of the circle corresponding to the position of the axis corresponding to the completion of the writing on the display screen 201. I do. The operation ends when all axes are written and verified. Although the case of “error end” is not described in the flowchart of FIG. 3 for convenience of description, the completion signal from the driving device 30A to the control unit 10B includes a flag that can distinguish “normal end” and “error end”. Then, the control unit 10B side receiving this may display, for example, x in the position of the circle corresponding to the position of the axis corresponding to the completion of erasure and the completion of writing on the display screen. Also, during normal operation ,
Since the control unit 10B is in communication with the driving device 30A, the control unit 10B includes a transfer S / W as a part of the system S / W.

Finally, after the power is turned off, the power is turned on again.
Then, normal operation starts. Note that the capacity of the RAM 303 is
8-bit data communication when communication is insufficient or communication is parallel
However, it is possible by the same method as in the first embodiment.

In the second embodiment, an example is shown in which a plurality of drive units S / W are allocated in the system memory 103B. However, the drive units S / W are allocated to the RS-232C device 51 and the secondary memory 5B.

A detailed description of the flash memory program of the drive unit 30A from the control unit 10C of the hierarchy 2 is omitted, but the boot ROM 1013 in the CPU 101 contains the transfer S / W to the drive unit 30A. When the computer 53 gives an instruction to jump to the first address, the process proceeds to step 2 of the first embodiment, so that it can be implemented in substantially the same manner as in the first embodiment.

Embodiment 4 FIG. Next, a fourth invention will be described based on an embodiment shown in the drawings. FIG. 13 shows an embodiment of the fourth invention, and is a block diagram showing an internal configuration of the stabilized DC power supply 11 of the numerical controller. In the figure, reference numeral 158A denotes a sequence circuit, which is different from the conventional sequence circuit 158 in that a servo type, a general-purpose input, and a general-purpose output are added. Those denoted by the same reference numerals as those in FIG. 28 indicate the same or the same elements. Here, as for the servo type and general-purpose input, the DC output power is supplied to the control unit 10 when the DC stabilized power supply 11 is in the operating state, and the signals output from the CPU 101 while the CPU 101 is operating are appropriately latched (FIG. (Not shown). General-purpose output is CPU
It is assumed to be an input signal to 101. These input / output signals are signals having an appropriate bit width according to the number of bits of the one-chip microcomputer in the sequence circuit 158A described later. When the one-chip microcomputer has a serial input / output, the servo type and the general-purpose input may be serial input and the general-purpose output may be serial output. in short,
It is only necessary that data can be exchanged with the CPU 101.

FIG. 18 shows an embodiment of the fourth invention, in which the H / W configuration of the numerical controller and the current consumption of the DC output of the stabilized DC power supply 11 are displayed on the display screen 201 of the operation board 20. is there. FIG. 19 shows an embodiment of the fourth invention. For 24 V output of the DC output of the stabilized DC power supply 11, the current consumption is displayed on the display screen 201 of the operation board 20.
FIG. The operation of FIGS. 13 and 14 will be described with reference to FIGS. In the above embodiment, the one-chip microcomputer 1581 is used, and the A / D
Since it takes time to convert analog data to digital data with a converter, analog signals are read at regular intervals using a timer interrupt as shown in FIG. It may be read each time.

In FIG. 17, in step 121, the A / D conversion value of the AC monitor is read, and in the case of undervoltage or overvoltage,
Turn on the AC voltage shortage flag and the AC voltage overvoltage flag. If it is determined that there is no AC input, the AC input disconnection flag is turned on. Here, the AC monitor is an input that has been level-converted, rectified, and smoothed by the auxiliary power supply 157 because the AC input voltage cannot be directly input to the one-chip microcomputer. 5V at step 122,
Reads A / D conversion values of + 12V and -12V, and in case of undervoltage or overvoltage, 5V undervoltage flag, 5V overvoltage flag, 12V undervoltage flag, 12V overvoltage flag, -12V undervoltage flag, -12V overvoltage Turn on the flag. In step 123, the A /
The D-converted value is read, and if the voltage is undervoltage or overvoltage, the 24V voltage undervoltage flag and the 24V voltage overvoltage flag are turned on.

In FIG. 15, when AC input is applied to the rectifier circuit 151 and the auxiliary power supply 157, step 10 is performed.
When the ON switch is pressed in step 1, the process proceeds to step 102.
If the OFF switch has not been pressed in step 102, the process proceeds to step 103. If the OFF switch is pressed in step 102, the process returns to step 101 and waits until the ON switch is pressed. In step 103, the ON / OFF signal is turned ON, and the switching unit 153 is turned ON. As a result, the power converted to DC by the rectifier circuit 151 and the smoothing circuit 152 is switched by the switching unit 153, and the transformer 159, the rectifier circuit 151C, and the smoothing circuit 152C
Through the rectifier circuit 151A, the smoothing circuit 152A,
± 12 V is output via the regulators 154 and 154A. The control for making the output 5 V is performed by the voltage detection circuit 15.
The feedback control is performed to feed back the voltage detected in step 6. When the switching unit 153 is turned on with the 5V output short-circuited, the current detection circuit 15
5A is an overcurrent, and the switching unit 153
Cut off the output of

In step 104, the process waits until the 5V and ± 12V outputs reach the rated value and the DC alarm (logical sum of undervoltage / overvoltage alarm of each of the 5V and ± 12V outputs) disappears. In step 105, the AC input disconnection signal is turned off.
And turns on the 24V ON signal. Then, the regulator 154B is turned on, the DC power input to the regulator 154B via the rectifier circuit 151B and the smoothing circuit 152B is adjusted to 24V by the regulator 154B, and 24V is output. Also in this case, if the regulator 154B is turned on while the 24V output is short-circuited,
The current detection circuit 155 detects an overcurrent, and shuts off the output of the regulator 154B. In the NC1D, generally, 5 V and ± 12 V are used inside the control unit 10, but 24 V is a contact input 40 of the operation board 20 and the machine 40.
2 and the contact output 403, 24V may have a considerable inrush current depending on the load. Step 1
Reference numeral 06 is provided as a countermeasure for ignoring any alarm at 24 V during the period of the inrush current, and waits for a predetermined time.

Step 107 checks whether a current exceeding the rated current flows to the load and the voltage is not lower than the rated value. If the voltage is insufficient, step 116 is executed.
Proceed to. In step 108, the DC stabilized power supply 11 is in a state where the start-up is completed. Then, it is checked whether or not the battery voltage is normal.
I do. Step 111 and subsequent steps are routines after normal startup. At step 111, it is checked whether the AC input is undervoltage or overvoltage. If the voltage is undervoltage or overvoltage, the AVR abnormality signal is turned on at step 112.
In step 113, it is checked whether the 5V and ± 12V voltages are insufficient or overvoltage. If the 5V and ± 12V voltages are insufficient or overvoltage, step 11 is executed.
4 to turn off the ON / OFF signal,
53 is turned off. That is, all DC outputs are turned off. In step 115, it is checked whether the 24V voltage is insufficient or overvoltage. If the 24V voltage is insufficient or overvoltage, the 24V ON signal is turned off and the 24V output is turned off in step 116. Step 11
In step 7, it is checked whether the AC input is turned off or the OFF switch is pressed. If the AC input is turned off or the OFF switch is pressed, the servo type is read in step 118, and the power is turned off in accordance with the read type. The power-off process may be various depending on the type of the driving device and the type of the machine. The general-purpose input shown in FIG. 14 can be used when it is desired to change the power-off processing for a type other than the type of the driving device.

Step 118 Example 1 shows the same sequence as the conventional example. In step 1181, the ON / OFF signal is turned off and the switching unit 153 is turned off after the instantaneous power failure allowable time of the NC 1. Then, the AC input disconnection signal is turned on.
Then, the CPU 101 is interrupted. CPU 101 is A
When the C input disconnection signal is turned on, processing such as saving necessary memory contents is performed before the DC output completely disappears. In step 1182, the CPU of the control unit 10 waits for the elapse of the processing time for turning off the power such as saving the memory contents, turns on the memory protection signal, and switches the power supply to the memory to the battery.

The energy of the power supply is supplied to the smoothing circuit 152.
And 152A, 152B and 152C, which vary depending on the AC input voltage, and generally, the higher the AC input voltage, the more energy is stored. Therefore, when the AC input voltage is high, the DC holding time can be made longer than when the AC input voltage is low. Step 118 Example 2 is an example in which the DC output is to be kept ON as long as possible by the power supply by using this. In this case, the withstand against an instantaneous power failure increases. In step 1181A, the AC monitor A
Calculate the 5V voltage holding time and the 24V voltage holding time from the AC voltage and the 5V current and the 24V current which can be obtained from the / D conversion value,
After the lapse of the time, the ON / OFF signal is turned off, and the switching unit 153 is turned off. Then, the AC input disconnection signal is turned ON to interrupt the CPU 101 to notify that the DC power is not supplied, and the CPU 101 performs processing such as saving necessary memory contents before the DC output is completely lost. In step 1182, the CPU of the control unit 10
Waits for the elapse of the processing time when the power is turned off, such as saving the contents of the memory, turns on the memory protection signal, and switches the power supply to the memory to the battery.

In the NC1, the 24 V DC output is used for a power circuit such as a relay, an EL display of an operation board, a motor power supply of a floppy disk, and the like.
Since it is open to machine manufacturers, it is also used for various devices connected to NC1. In this case, the relay is instantaneously driven, a large rush current exceeding the specification of the DC stabilized power supply 11 flows to the EL display or the floppy disk, and the 24 V output drops instantaneously.
And the 24 V output is turned off, or the regulator 154B is turned on by the current detection circuit 115 shown in FIG.
In general, in the rising sequence, 5V which is the control power supply is first supplied and the power supply is 2
It is a rule to leave 4V. On the other hand, with respect to the falling sequence, in many cases usually no problem, on the relationship between open 24V to the machine manufacturer, depending on the equipment to be connected, out unexpected output momentarily, malfunction device connected It is conceivable that some troubles such as leading to trouble may occur. Assuming such a case, Step 118 Example 3 is an example in which 24 V, which is the power supply, is dropped first in the fall sequence, and then 5 V, which is the control power supply, is turned off. 24V · O after the instantaneous power failure allowable time of NC1 in step 1181B
The N signal is turned off, and first, 24V is turned off. Then
After a certain time, the ON / OFF is turned off, and the switching unit 1
53 is turned off. Then, the AC input disconnection signal is turned on,
An interrupt is issued to the CPU 101. When the AC input disconnection signal is turned ON, the CPU 101 performs processing such as saving necessary memory contents before the DC output completely disappears.

In step 1182, the control unit 10 waits for the lapse of the processing time when the power is turned off, such as saving the contents of the memory, and turns on the memory protection signal to switch the power supply to the memory to the battery. Step 118 Example 4 is Step 11
Eighth Modification of Example 2 is an example in which 5 V is to be held to the last minute. In step 1181C, 5V A /
The D-converted value is always read, and the moment when the 5V voltage drops from this is captured, the ON / OFF signal is turned off, and the switching unit 153 is turned off. Then, the AC input disconnection signal is turned on.
Then, the CPU 101 is interrupted. CPU 101 is D
Before the C output completely disappears, processing such as saving required memory contents is performed.

At step 1182, C of control unit 10
The PU waits for the elapse of the processing time when the power is turned off, such as saving the contents of the memory, and turns on the memory protection signal to switch the power supply to the memory to the battery. In the case where the AC input temporarily drops due to an instantaneous power failure and returns, the 24V smoothing circuit 152B
If the energy stored in the power supply is lost before the energy stored in the 5V smoothing circuit 152C, 24V drops momentarily but the 24V signal is not turned off. Turn ON again.
Step 118 Example 4 can be used when such circumstances allow.

Although the case of an instantaneous power failure is not described in the flowcharts of FIGS.
, The AC input is interrupted, and the process proceeds to step 118. In step 1181, step 1181A, step 1181B, and step 1181C, if the AC input is recovered after the time when normally the ON / OFF signal should be turned off has elapsed, that is, the AC input interrupt flag Is turned off,
Return to step 111 without turning OFF.
In this case, even if an instantaneous power failure occurs, the DC output of the stabilized DC power supply 11 does not need to be turned off. Further, a method of setting the servo type in the sequence circuit 158A is shown in FIG.
MPU 301 can read the contents,
Communication is made to the control unit 10, which can be automatically set because the CPU 101 can output it as a general-purpose input to the sequence circuit 158A of the stabilized DC power supply 11.

Another advantage of using a one-chip microcomputer for the sequence circuit 158A is that, in connection with the seventh embodiment, a flash memory device in a numerical controller connected to a host computer via a network or the like is provided. When the system memory and the machine control memory are programmed, when verifying whether or not the programming has been performed correctly, the supply voltage to the flash memory may be originally kept at 5 V.
It can be said that it is safer to change the voltage to 5.5V. For this purpose, in FIG. 13, the general-purpose input of the sequence circuit 158A is set to a 5V voltage change command, and the command value is changed by the CPU 101 at the time of comparison. For example, assuming that the general-purpose input is 2 bits, “00” is 5 V, “01” is 4.5 V, and “1” is “1”.
If “0” corresponds to 5.5V and an electronic volume (not shown) or the like whose resistance value changes by a pulse input is used as the 5V adjustment output of the sequence circuit 158A, the CPU 101
The circuit becomes simpler than driving this electronic volume directly, and a change in voltage of 5 V with respect to the command value is 4.75.
V, 5.0V, and 5.25V can be easily changed. In short, NC1 can be used as a high-grade ROM writer.

Embodiment 5 FIG. In the stabilized power supply device 11 according to the fourth embodiment, each DC output has a power supply sequence, and a microcomputer and NVRAM are used as a sequence circuit. If a power failure occurs, this history is stored in NVRA
Write to M1584. And NVRAM
The internal state of 1584 is determined by the CPU 10 as a general-purpose output signal.
1 can be received and displayed on the display screen 201 of the operation board 20 through the operation board I / F 104,
The history of instantaneous power failure can be displayed on the display screen of the operation board.

In FIG. 13, the 5V output and the 24V output have current detection circuits 155A and 155, respectively.
Since the signal is input to the / D converter via the filter circuit 1583, the measured value of the current consumption can be known. Also,
For the H / W configuration of the driving device 30A, see the driving device 30A.
Since the control unit 10A and the control unit 10A have communication means, the type of the driving device for each axis can be known by the above-described method. This is displayed on the display screen 201 of the operation board.

Embodiment 7 FIG. In the stabilized power supply device of the sixth embodiment, each DC output has a power supply sequence, a sequence circuit for controlling the power supply sequence is configured using a microcomputer, and a current value of the DC output is input to the sequence circuit. By this, the graph of the measured DC output current can be divided into the minimum current, the maximum current in the operating state, and the rated current allowed for the stabilized power supply device, and can be displayed on the operation board in a bar graph for each color. . 19 shows one embodiment of the fifth invention, a view among, graphic representation for the current consumption of the 24V current consumption in FIG. 18. Since the 24V DC output is open to the machine maker, it changes depending on the connected equipment and the operating state of the NC. In the figure, red is the rated current of 24 V, blue is the minimum current in the operating state, and yellow is the variation that changes every moment. In FIG. 14, a one-chip microcomputer 1581

Embodiment 8 FIG. Next, a sixth invention will be described based on an embodiment shown in the drawings. FIG. 20 shows an embodiment of the sixth invention, and is a block diagram showing the overall configuration in a case where a sequence control device such as a multi-axis controller or a PC shares a display screen of an operation board 20A which is an NC display device. FIG. In the figure, the sequence controller 56 is directly connected to the operation board 20A. 24 and 30 denote the same or equivalent elements. FIG. 21 shows an embodiment of the sixth invention, and is a detailed block diagram mainly showing the operation board of FIG. FIG. 22 shows an embodiment of the sixth invention, and is a block diagram showing an internal configuration of the operation board control printed board 208 in the case of a system having a CRT controller on the operation board control printed board 208 side. In the figure, 214 is a text RAM having twice the storage capacity of the text RAM 214A, and 218A is a second communication I / F circuit, which is connected to the sequence control device through a connector 219D.

FIG. 23 shows an embodiment of the sixth invention, and is a detailed block diagram mainly showing the text RAM 214 of FIG. In the figure, 2141 is a text RA
The RAM, which is the main body of M214, stores the screen display data of the control unit in the lower address half, and the screen display data of the multi-axis controller in the upper address half. Reference numeral 2142 denotes MPU addresses A0 to A13, 21 output when the MPU accesses the RAM 2141
43 is an MPU for writing data to the RAM 2141
The data contents of the data buses D0 to D7 are character code data. 2144 is CRTC 213 RAM
The CRTC lower addresses A0 to A12 and 2145 output when accessing 2141 are the highest address A1.
3, 2146, the access of the RAM 2141 is performed by the MPU 21
A multiplexer for switching between the 0 side and the CRTC 213 side; 2147, a RAM address bus of the RAM 2141; 2148, a RAM data bus of the RAM 2141;
149 is a buffer between the MPU 210 and the RAM data bus of the RAM 2141, 2150 is a latch,
The output data of 2141 and the CRTC raster address are latched. 2151 is an MPU 210 control signal,
2152 and 2152A are flip-flops.

Next, the operation will be described. In this embodiment, since the communication I / F circuit is provided on both the control unit side and the sequence control device side in the operation board control printed board 208, the display screen 201 displays the control unit side. Also, even when the display is performed on the sequence control device side, it is possible to communicate with both the control unit side and the sequence control device side. Output data of the control unit 10 is periodically transmitted to the communication I / F circuit 218. The output data includes both display data to be displayed on the display screen 201 and data to be output to the lamp 207 in the machine operation board 205 in the numerical control operation unit 21. MP
U210 discriminates the output data according to a program written in the ROM 211 in advance, and display data to be displayed on the display screen 201 is written in the first half of the text RAM 214. This is done as follows. It is assumed that the multiplexer is on the MPU side by an arbiter (not shown). MPU 210 sets M to the MPU address bus.
When PU addresses A0 to A13 2142 are output, RA
MPU addresses A0 to A13 are input to the M address bus. At the same time, MPU data D0
To D7 2143 are output and input to the RAM data bus 2148 through the buffer 2149. Thus, the display data of the control unit 10 to be displayed on the display screen is written. Since the data is NC data at this time, A1
3 is a LOW level.

The output data of the sequence controller 56A is also transmitted to the communication I / F circuit 218A periodically. This output data includes both display data to be displayed on the display screen 201 and data to be output to the lamp 207 in the sequence control device operation unit 21A. MPU 210 is R
In accordance with a program written in advance in the OM 211, display data to be discriminated from the output data and displayed on the display screen 201 is written in the second half of the text RAM 214. This is performed in the same manner as in the case of the control unit 10 described above, but this time A13 is at the HIGH level. Thus, writing to the text RAM is always possible.

Next, the display on the display screen 201 will be described. The CRTC 213 constantly scans the text RAM 214. More specifically, when the CRTC 213 accesses the text RAM 214, an arbiter (not shown) sets the multiplexer 2146 to the B side, that is, the CRTC.
Is on the side. The CRTC 213 address is CRTC
The lower addresses A0 to A12 and the multiplexer 21
The data is input to the RAM 2141 through 46. RAM 21
Flip-flop 214 as the highest address of 41
5 is input. The output of the flip-flop 2145 is set to a LOW level in the case of display on the control unit side, and to a HIGH level in the case of display on the sequence control device side.

Now, assuming that the display on the control unit side is performed, the highest address of the RAM 2141 is at the LOW level, and the data on the control unit side is stored in the RAM data bus 2.
148. This is the character code corresponding to the position where the character on the display screen 201 is to be displayed. This code is latched by the latch 2150 together with the CRTC raster address, and
15 addresses are input. Then, the character generator 215 outputs data that is character information obtained by decomposing the character in units of pixels on the screen, and outputs the CRT · I
/ F216. The CRT I / F 216 converts this input signal into a serial video signal having a dot clock frequency conforming to the specification of the display screen 201, and
Output to 01. Thus, the display data to be displayed on the display screen 201 of the output data of the control unit 10 is displayed on the display screen 201.

On the other hand, data to be output to the lamp 207 is transmitted via the key I / F / lamp output 217 to the NC operation unit 2.
The lamp 207 of the first machine operation board 205 is turned on .

In the case of the display on the sequence controller side, R
