Abstract

PURPOSE:To curtail the number of programs provided on a main device side in order to allow an operating state of plural kinds of subordinate devices which are operated by being subordinate to the main device provided with a microprogram, and provided with a microprocessor, respectively to conform to an operating state of the main device. CONSTITUTION:Restart index data of a subordinate device restart management signal informed to a subordinate device from a main device is constituted, and transmitted to the subordinate device by setting its initial value to '0', and without being aware of the kind of the subordinate device. Subsequently, by updating and transmitting the restart index data without being aware of the kind of the subordinate device, the main device and the subordinate device are synchronized. When the main device is allowed to conform to an operating state of the subordinate device, the operating states can be allowed to conform to each other without considering each separate condition of plural kinds of subordinate devices, therefore, it will suffice that this kinds of program prepared on the main device side is prepared by only one kind, and the number of programs which enter into the main device side can be curtailed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device accommodating a microprocessor, and more particularly to a program for managing such a device.

[0002]

2. Description of the Related Art Conventionally, in this type of system for managing restart of a slave device from a master device, a signal having a meaning to define each operation is transmitted to a slave device from a signal transmitted from the master device to the slave device. It was set according to the individual circumstances of the device.
Therefore, a program (hereinafter, this program is referred to as a slave device restart management program) for executing processing according to the individual circumstances of the slave device is created on the master device side, and the master device side is prepared in accordance with the operating states of the slave devices covering a plurality of types. The program controlled the restart of the slave device from.

[0003]

The problem to be solved is to restart the slave unit on the master unit side in order to match the operating states of the master unit and the slave unit according to each slave unit and individual circumstances of the slave unit. The point is that the amount of programs increases because a management program must be created.

[0004]

According to the present invention, in order to match the operating states of the master device and the slave device, a signal between the master device and the slave device used (hereinafter referred to as slave device restart management signal) is used. , Enter hexadecimal numerical data that increases in increments of 1 from 0, and use this data as common index data to synchronize multiple slave devices from the main device (hereinafter, this data will be used as restart index data. That.)
However, the slave device restart management program on the main unit side sets the restart index data, which increases in increments of 1 from 0, to the slave device restart management signal without considering the characteristics of each slave device, and sends it to the slave device, The device is characterized in that the restart index data from the main device is interpreted according to the characteristics of the slave device, and a process for adjusting the operating state of the state control circuit device to the operating state of the main device is executed.

[0005]

The present invention will be described in detail with reference to the drawings. FIG. 1 is a flow chart showing an embodiment of a slave device restart management program system according to the present invention. In FIG. 1, I represents a variable for storing the restart index data, and as an example of the restart index data, the one shown in Table 1 at the end of “Detailed Description of the Invention” is used. In the flow 5, the initial value “0” of the index is set as the variable I for storing the restart index data. In flow 10, the slave device restart management signal sent to the slave device is edited as shown in FIG. 2, and in flow 15, slave device restart management is sent to the corresponding slave device.
In the flow 20, the processing completion of the slave device restart management signal is received from the slave device.

In the flow 25, it is checked whether or not the transmission of the corresponding index data has been completed. When not completed, the flow returns to the flow 10 and the subsequent data is transmitted according to the flow 10. If completed, flow 30
And make the following index data. At this time, the value of the restart index data expected next from the slave device is set to the variable I based on the signal received from the slave device. Flow 35
Check the restart index data with. If this value exceeds the final value (in this example, 5 is shown), it indicates that the operating states of the master device and the slave device match, and the process is terminated. If not, the process returns to the flow 10 to send the slave device restart management signal having the next restart index data.

Regarding the slave device restart management program of the main device, the definition of the restart index data is determined as shown in the example of Table 1 described at the end of the detailed description of the invention, and the slave device restart management signal is set to the restart index data 0. To the slave device in order. Interpret the information received by the slave device according to the characteristics unique to the slave device, perform the most appropriate processing on the slave device,
A response indicating the end of processing is returned to the main unit. At this time, the main device is also notified of the value of the restart index data expected by the next device. When the master device receives the response from the slave device, it sends the next restart index data that is continuous or the restart index data that the slave device expects. By repeating this, the final restart index data (“5” in this example) is sent, and upon receipt of this response, the operating states of the main device and the slave device match.

[0008]

As described above, the present invention raises the slave unit restart management signal for adjusting the operating states of the main unit and the slave unit from 0 to 1, and the index for adjusting the operating state to the data. By setting the index data having the meaning of, the main device only sends the restart index data to the slave device in order from 0, and the master device and the slave device can be connected without considering the individual conditions of the slave device. There is an advantage that the operating conditions can be adjusted. Therefore, it is effective to prepare one type of slave device operation management program for a plurality of types of slave devices.
