00 is a sequence control unit for setting internal state data of 00.

When an alarm or error occurs in the numerical control device, the operator uses the display device (not shown) such as a CRT of the numerical control device 800 or the operation board (not shown) to detect the alarm or error. In order to release the alarm, the internal state data of the numerical control device stored in the internal state memory 11 is referred to, which internal state has caused the alarm or error, and the alarm or error is released. The internal state data of the numerical control device that can be referred to include the history of alarms and errors that occurred in the numerical control device, the history of operator operations, the history of input / output signals between the machine and the numerical control device, and the generation of the history. There is time etc.

FIG. 9 shows an example of a conventional communication mode in which the operator refers to the internal state data of the numerical controller from the host. The operator sends a command from the host 1 to the numerical controller 800 to read the internal state data. In the numerical controller 800, the input / output processing unit 3 is
The designated internal state data is read from the internal state memory 11. The numerical controller 800 transmits the read internal state data to the host 1 as a response. This allows
The operator can refer to one piece of internal state data of the numerical control device. For example, in the case of alarms and errors of numerical control devices, there are servo alarms, program errors, machine alarms, etc., and there are various ways to deal with them, so numerical values must be set in order to make appropriate judgments and corrective actions. It is necessary to know the internal state data of the control device in as much detail as possible. Further, in order to know the internal state data of the numerical control apparatus in detail, the internal state data of the numerical control apparatus that is inevitably referred to becomes large, and the operator performs the above operation by the number of necessary internal state data of the numerical control apparatus. I was repeating.

For example, 8 am every day for processing work management
Hour, or a specific time every Friday at 5pm,
When confirming the internal state data of the numerical control device such as the number of workpieces machined or the operating time of the machine, the operator goes to the installation place of the numerical control device 800 or the host 1 at every specific time when the data is required, and then the internal state data I was doing a read operation.

Although the operator has been operating the machine as described above, all that the numerical control device can automatically perform is described in the work instruction data, and this is executed in batch processing so that only the operator can perform the operation. It is proposed that the operator only do what he cannot. Figure 1

In the conventional numerical control apparatus, the number of operations by the operator is large, which is a work burden on the operator. Further, even with a numerical controller having a batch processing function, there is a problem in that management of batch data is difficult. In the conventional numerical control device, when an alarm or an error occurs, the operator releases the alarm or the error by using a display device (not shown) such as a CRT of the numerical control device or an operation board (not shown). Therefore, the history of alarms and errors that have occurred in the numerical control device,
The operator's operation history, the history of input / output signals between the machine and the numerical control device, and the internal state data of many numerical control devices such as the generation time of these history are referred to. However, since the internal state data of these numerical control devices include many things that are unrelated to the cause of the alarm or error that you want to clear, the operator cannot determine which internal state data caused the alarm or error. It is necessary to determine if there is any and cancel the alarm and error, and the time required for this work depends on the experience and knowledge of the operator. For this reason, there is a problem that an operator who has little work experience cannot easily cancel an alarm or an error, which causes a delay in work.

Further, in the conventional numerical control device, an operator can perform batch processing control by operating a key on an operation board (not shown) of the numerical control device, but when the operator controls the numerical control device from the host. There is a problem that the batch data search processing of the numerical control device and the batch processing control of each numerical control device cannot be performed without going through the sequence control unit 9 or the sequence control unit 9 and the machining program processing unit 5. there were.

Further, in the conventional numerical control device, numerical control such as the number of workpieces to be machined and machine operating time is performed at a specific time such as 8 am every day or 5 pm every Friday for machining work management. When confirming the internal state data of the device, the operator has to go to the installation location of the numerical control device or the host and perform the read operation of the internal state data at every specific time when the data is required. This work has no problem if the duration is short, but there is a problem in that it takes a burden on the operator if the duration is long.

FIG. 4 is a flow of a process in which the batch processing unit 4a stores the internal state data in the numerical controller 100 in the data storage unit 12, which will be described with reference to the batch data shown in FIG.

In step 101, when the batch data instructions are sequentially executed, it is checked whether the batch data instructions store the internal state data of the numerical controller 100. This check is done by @DATASV in Figure 2.
@DA with the instruction (DATASV3.CLG, 64)
Based on the data TASV, it is determined that the batch data instruction stores the internal state data of the numerical control device 100. Batch data instructions are @DATAS
If the data is V, the process proceeds to step 102, and if the data @DATASV does not exist in the batch data, the process proceeds to step 105.

When it is desired to read out a plurality of internal state data required for knowing the internal state data of 0 in detail, the host 1 sends a command for starting batch processing to the numerical controller 200, and the input / output processing unit 3b performs batch processing. The command is transmitted to the control unit 13a. The batch processing control unit 13a activates the batch processing unit 4b, and the batch processing unit 4b reads out the necessary internal state data of the numerical control device 200 registered in the batch data from the internal state memory 11 and stores it in the data storage unit 12. To do. Next, the operator sends a command for outputting the internal state data stored in the data storage unit 12 from the host 1 to the numerical control device 200, and the input / output processing unit 3b stores the necessary numerical control data stored in the data storage unit 12. Since the internal state data of the apparatus is output to the host 1, the stored internal state data of the numerical control apparatus can be collectively referred to. Therefore, the operator registers the internal state data of the numerical control device 200 necessary for the batch data, and the host 1 sends the above-mentioned two commands to the numerical control device 200 to perform the necessary numerical control. It is possible to refer to the internal state data of the device.

When the number of internal state data of the numerical controller required is only one, the operator sends a command to read the internal state data from the host 1 instead of the command to start the batch processing. It is also possible to refer to necessary internal state data.

If the batch processing is to be canceled due to some factor during the execution of the batch processing, the operator sends a command for canceling the batch processing from the host 1 to the numerical control device 200, and the batch processing section 4b executes the batch processing. Stop execution of the process.

Example 3. FIG. 7 is a block diagram of essential parts of a numerical controller according to an embodiment of the fourth invention. In the figure, 300 is a numerical controller, 2c is a control unit, 3b is an input / output processing unit, 4b is a batch processing unit, 13b is a batch processing control unit, and 14 is a time setting unit. Numerical control device 300
Is different from the numerical controller 100 shown in FIG. 1 in that a batch processing control unit 13b and a time setting unit 14 are provided, and processing is added to the input / output processing unit 3b and the batch processing unit 4b. There is.

The time setting unit 14 performs a process of outputting a start command to the batch processing control unit 13b at each time set by the operator.

The batch processing control unit 13b includes a time setting unit 1
In response to the activation instruction from 4, the processing for activating the batch processing unit 4b is performed.

For this reason, the operator uses the numerical control device 30.
When it is desired to read the internal state data of 0 every specific time, the internal state data of the numerical controller 300 to be read is registered in the batch data, and the specific time for executing the batch processing unit 4b is set in the time setting unit 14 by The numerical control device 300 itself can store the internal state data at the set time.
