Abstract

PURPOSE:To speedily inform an operator that the input sequence of a command is different by checking the input sequence of a series of commands to combine plural commands from an operator console. CONSTITUTION:A command group identification code and the input sequence of the individual command of the command group, namely, the command sequence are inputted and stored in a command sequence storage means 3 beforehand. When the command group having one of command group identification codes is inputted from an operator console 1, the command sequence corresponding to the received command group identification code is outputted to a command sequence comparing means 7, and it is compared with the command to be temporarily stored in a command temporary storage means 6. In the case of the non-coincidence, the fact that the input command sequence is wrong is reported from a processing part 8 to the operator console 1. Thus, when the input sequence of a series of commands is different from the sequence to be specified beforehand, the operator can be speedily informed of it.

[Industrial application field]

The present invention relates to a command sequence abnormality detection method for detecting errors in the input order of a series of commands input to a processing device from an operator console.

Conventionally, operator consoles that are connected to a processing device to set or read internal information of the processing device have mainly had relatively simple functions. Such operator consoles use a method of individually inputting commands to the processing device depending on the content to be processed. For example, when reading a register, the operator console inputs a specific command to the processing device. By inputting a read register command, the contents of the corresponding register in the processing unit were read and sent to the operator console.

However, in recent years, operator consoles have become more sophisticated, and it is now possible to combine multiple commands from the operator console, input them to the processing device, and then edit the obtained information again on the operator console side. Processing has begun.

However, even when multiple commands are input as described above, conventional methods do not perform abnormality detection on multiple commands comprehensively, but only on individual commands. Even if there is an error in the order, that is, the command sequence, the error may not be detected or may be discovered after processing has proceeded.

Therefore, there is a need for a command sequence abnormality detection method that promptly detects the abnormality when there is an error in the command sequence and notifies the operator console of the error.

[Conventional technology]

FIG. 4 is a block diagram of the conventional system, and FIG. 5 is an example of a sequence of the conventional system.

In FIG. 4, when setting or reading the conventional method inside the processing device from the operator console 21,
The operator console individually inputs commands to the processing device 22 according to the content to be processed. For example, when reading a specific register, the operator console 21 inputs a read command to the processing device 22 that includes designation of the register number. The command is sent from the transfer control section 22 of the operator console 21 to the transfer control section 24 of the processing device 23, where the data bits are subjected to serial/parallel conversion, etc., and then transferred to the processing section 25. Processing section 2
In step 5, the input command is decoded, and if it is a register read, the contents of the register with the designated number (not shown) are read and sent to the transfer control unit 24, where the data bits are read. Operator console 21 performs serial/parallel conversion, data transmission control, etc.
The data is sent to the transfer control unit 22 of.

FIG. 5 shows the transmission and reception sequence of commands and data between the operator console 21 and the processing device 23 when register reading processing as described above is performed for a plurality of registers. As shown in FIG. 5, reading processing for each register is performed independently, and for example, when processing data received on the operator console 21 side, it is necessary to read the registers in a certain order. If you enter the reading order incorrectly,
On the processing device 23 side, each command is processed independently and the relationship between commands is not monitored, so errors in the input order of commands are not detected.

[Problem to be solved by the invention]

As described above, in conventional methods, when processing a series of commands, there is no means to detect errors in the command sequence, which may result in errors in the processing results or errors that are discovered after processing has proceeded. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a command sequence abnormality detection method that promptly notifies an operator when the input order of commands from an operator console differs from a predetermined sequence.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention.

1 is an operator console that inputs and outputs commands and data for setting and reading internal information of the processing device;
Reference numeral 2 denotes a processing device that performs processing by controlling storage devices, input/output devices, etc. (not shown) by inputting commands from the operator console 1, etc.; 3 to 8 are various means provided within the processing device 2; It's like that.

3 is a command sequence storage means that assigns a command group identification code in advance to each series of command groups that are continuously input from the operator console 1, and stores the command sequence in advance for each command group identification code; When input information to which the command group identification code is added is received, a command detection means detects and outputs the command group identification code and command from the input information; 6 is a command group identification code temporary storage means for temporarily storing command group identification codes to be outputted to the command sequence storage means 3; 6 is a command temporary storage means for temporarily storing commands output from the command detection means 4 in the order of input; , 7 inputs the temporarily stored command sequence from the command temporary storage means 6 each time a command is input to the command temporary storage means 6, and inputs the command sequence stored from the command sequence storage means 3. 8 is a command sequence comparing means for receiving and comparing the command sequences corresponding to the command group identification codes received from the command group identification code temporary storage means 5 and outputting the comparison results to the processing section described later; From the command sequence comparison means 7, the command
This is a processing unit that receives sequence comparison results and sends abnormality detection information to the operator console if the comparison results do not match.

[For production]

In FIG. m1, a command group identification code is assigned in advance to a series of command groups that are often input successively from the operator console 11 for each command group. For example, a series of processes consisting of a combination of multiple commands, such as reading the contents of all registers, such as a first register read process, a second register read process, etc., is treated as one command group and a command group identification code is assigned. I'll keep it. the command group identification code of a command group having such a command group identification code and the input order of the individual commands of the command group;
That is, a command sequence is input in advance into the command sequence storage means 3 from an input device (not shown) and stored (registered). Note that the command sequence stored in the command sequence storage means 3 can be changed according to a prescribed procedure.

When a command group having one of the above-mentioned command group identification codes is input from the operator console 1, the command group identification code is inputted first, and then the commands are inputted sequentially from the first command in the command sequence.

When a command group identification code is first input, the command detection means 4 identifies the command group identification code, sends it to the command group identification code temporary storage means 5, and then inputs it to the command sequence storage means 3. Next, when a command is input, the command detection means 4 detects the command in the same manner as described above.
The command is detected and temporarily stored in the command temporary storage means 6. Further, the command temporary storage means 5 notifies the command sequence storage means 3 that the command has been input.

Upon receiving the information, the command sequence storage means 3 outputs a command sequence of the command group identification code corresponding to the command group identification code received from the command group identification code temporary storage means 5 to the command sequence comparison means 7. . On the other hand, the command temporarily stored in the command temporary storage means 7 is also sent to the command sequence comparison means 6 and compared with the command sequence stored in the command sequence storage means 3.

The comparison result is sent to the processing unit 8, and at this stage it is determined whether the first command is appropriate or not. If the comparison result matches, the command input from the operator console 11 is processed, and if they do not match, the command input from the operator console 11 is More operator
Inform console 11 that the input command sequence is incorrect. Thereafter, the above process is repeated every time a command is input.

Note that it is also possible to input a plurality of commands to which no command group identification code is attached, but in this case, abnormality detection is not performed in the command sequence, but abnormality detection is performed in units of individual commands.

[Example] Fig. 2 is a configuration diagram of an embodiment of the present invention, and Fig. 3 is a configuration diagram of an embodiment of the present invention.
FIG. 3 is a sequence diagram based on the configuration diagram of FIG.

In Fig. 2, the same parts as in Fig. 1 are indicated by the same symbols.
11 is a transfer control unit of the operator console 1, 12 is a transfer control unit of the processing device 2, 13 is a command sequence storage circuit, 14 is a command detection circuit, and 15 is a command group identification code input from the operator console 1. 16 is a buffer register (B) for temporarily storing commands; 17 is a command/sequence comparing circuit; 18 is a buffer register (A) for temporarily storing commands; 18 is a buffer register (B) for temporarily storing commands; 19 is a microprocessor that controls each circuit in the transfer control section 2 of the processing device 2; Note that connections between the microprocessor 19 and each circuit are not shown.

In FIG. 2, a command group identification code assigned in advance to each series of command groups input from the operator console 1 and a command sequence for each command group identification code are input in advance from an input device (not shown) to command - Store it in the sequence storage circuit 13. Further, when inputting a command group having one of the above-mentioned command group identification codes from the operator console 1, the command group identification code is added and a series of commands according to the command sequence is input.

Under the above state and conditions, when information is sent from the transfer control unit 11 of the operator console 1, the serially sent information bits are converted into parallel bits in the serial/parallel conversion circuit 18, and the command is detected. The signal is sent to circuit 14. When the command detection circuit 14 first detects a command group identification code, it sends the command group identification code to the buffer register 15.

The buffer register 15 temporarily stores the command group identification code and sends the stored command group identification code to the command sequence storage circuit 13. Next, when a command is input, the command detection circuit 14 identifies the command and sends it to the buffer register 16. buffer register 1
6 temporarily stores the command and sends it to the command/sequence comparison circuit I7, and also notifies the command/sequence storage 813 that the command has been input.

When the command sequence storage circuit 13 receives information about the input command, it outputs the command sequence of the command group identification code previously received from the buffer register 15 to the command sequence comparison circuit 17. The command sequence comparison circuit 17 first compares the buffer register 16 with the buffer register 16.
The command received from the command sequence storage circuit 13 is compared with the command received from the command sequence storage circuit 13, and the comparison result is sent to the processing section 8.

If the comparison results match, the processing unit 8 processes the command input from the operator console 1, and if they do not match, it notifies the operator console 1 that the input command sequence is incorrect. below,
Repeat the above process each time a command is input.

Note that when sending the command sequence stored in the command sequence storage circuit 13 to the command sequence comparison circuit 17, even if the entire command sequence is sent when the command group identification code is received from the buffer register 15, the command is not received. You may send only the relevant command each time. Furthermore, the same effect can be achieved whether the entire sequence from the first command to the latest command is compared or only the latest command after a match is confirmed. Although various modifications can be made to these comparison methods, they are not excluded from the present invention.

FIG. 3 is an example of a sequence based on the configuration diagram of the embodiment shown in FIG. 2 described above.

FIG. 3 shows all N registers (not shown) of the processing device, that is, registers from number 0 to number N CREG 0-
For an example of reading the contents of REG N), the operator
The sequence of sending and receiving commands and data between the console and the processing device is shown. As is clear from the figure,
On the processing device side, each time a command is received from the operator console, the command sequence is compared,
Since it is checked whether the input order of commands is correct, errors in the input order of commands will not cause errors in the processing results, and errors will not be discovered after the processing has proceeded.

Although FIG. 3 shows an example of only register reading, it goes without saying that it can be applied to more complex combinations of commands, and the more complex the combination of commands, the more effective it is.

〔Effect of the invention〕

As explained above, according to the present invention, when processing is performed by inputting a series of commands that are a combination of multiple commands from the operator console, the input order of the commands is checked, so that incorrect processing or This eliminates the need for rework due to discovering errors after processing has progressed, which greatly contributes to improving the input efficiency from the operator console.
