2. Description of the Related Art When inspecting a device such as a controller for controlling temperature, a large number of inspection commands are sent to a controller via a communication line, and the controller operates from response messages corresponding to the respective sent inspection commands. Is determined to be normal. Therefore, in order to perform these inspections efficiently, it is necessary to generate a large number of inspection commands with good reproducibility, and JP-A-2-82951 (referred to as prior art 1) and JP-A-4-178858 (referred to as prior art 2). Technology) has been proposed to solve this problem.

In the prior art 1, desired inspection setting data is registered in the storage device in advance by using the inspection setting data registration key. At the time of inspection, the reproducibility of the inspection is improved by performing the inspection according to the inspection setting data registered in the storage device.

In the prior art 2, a personal computer (personal computer 1) that executes a communication program to be inspected according to an input from a keyboard or a mouse, and another personal computer (personal computer 2) different from the personal computer 1 I am preparing. The output of the personal computer 2 is connected to the input terminal of the keyboard or mouse of the personal computer 1. Then, in the personal computer 2, a data file corresponding to the input from the keyboard or mouse is created, and the data of this data file is sent to the personal computer 1.

Therefore, when the communication program is inspected on the personal computer 1 side, data corresponding to this operation is given as data from the data file without operating the keyboard or mouse, so that the reproducibility of the input is guaranteed. To be done. Moreover, the efficiency of the input is improved.

[0006]

However, in the case where the object of inspection is an apparatus manufactured in accordance with the customer's request such as a temperature control controller, the specification of each apparatus is different, and therefore the inspection is performed. The content also needs to be changed according to the specifications. Therefore, when the prior arts 1 and 2 are applied to this inspection, it becomes difficult to share data in the inspection of each device. This means that it is necessary to create a data file of the inspection content corresponding to each device to be inspected, which causes a problem that it takes time to create the data file.

The present invention was devised to solve the above problems, and its purpose is to describe an inspection procedure as a combination of general-purpose inspection contents, and to change the inspection contents, only describe the inspection procedure. It is an object of the present invention to provide an inspection device for a controller, which can reduce the trouble of creating data for inspection by responding with a change.

[0008]

In order to solve the above problems, the controller inspection device of the present invention is connected via a communication line, and when an inspection command is given,
It is applied to an inspection device of a controller that executes an operation corresponding to a given inspection command and returns a response message, and an inspection command file in which a plurality of inspection commands are stored so as to be distinguishable from each other by a command label, and a plurality of inspection command files are stored. The response message file in which the response message of the above is stored so as to be distinguishable from each other by the message label, and the combination of the inspection command and the response message returned from the controller in response to the inspection command is a combination of the command label and the message label,
An inspection procedure file in which each of these combinations is stored in order according to the inspection procedure, and a combination of the command label and the message label is read out according to the order ordered in this inspection procedure file, and the read command label and message label Of a combination of the inspection command file and the response message file to convert the combination of the inspection command file and the response message file into a combination of the inspection command and the response message, and the inspection command that is one of the combinations converted by the procedure conversion unit. When the response message returned from the controller in response to the sent inspection command is compared with the response message that is the other one of the combination and the comparison in this operation determination unit indicates a match. Displays that the operation of the controller is normal, when not exhibit coincidence is a structure in which a display unit for displaying that the controller of the operation is bad.

[0009]

In the inspection procedure file, the combination of the command label and the message label is stored in order according to the inspection procedure. Therefore, the procedure conversion unit reads the combination according to the ordering. Then, from the read combination, the command label is converted into the inspection command by referring to the inspection command file, and the message label is converted into the response message by referring to the response message file. In other words, from the procedure converter,
The combination of the inspection command and the response message is sent in the order according to the inspection procedure.

This combination is a combination of the inspection command to be sent to the controller and the response message that is returned from the controller in response to this inspection command. Therefore, the operation determination unit sends an inspection command that is one of the combinations to the controller, and compares the response message returned from the controller with the response message that is the other of the combinations. When the comparison result shows a match, the display unit determines that the operation of the controller is normal, and displays that fact. If they do not match, it is determined that the operation of the controller is defective, and a message to that effect is displayed.

To do. Further, the response message is compared with the response message returned from the controller 11 in response to the transmitted inspection command.

The display unit 13 is a block for displaying that the operation of the controller 11 is normal when the comparison shows a match and displays that the operation is defective when the comparison does not match, based on the comparison result of the operation determination unit 12. Has become. Similarly, when the operation determination unit 12 indicates that the response message from the controller 11 has not been returned within the waiting time defined by the field 33, the operation failure is similarly displayed.

The inspection content editing unit 18 is a block for creating each of the inspection procedure file 14, the response message file 16, and the inspection command file 17 prior to the inspection of the controller 11.

FIG. 2 is a flow chart showing the operation of the embodiment of the present invention, and FIG. 7 is an explanatory view showing the communication procedure between the operation judging section 12 and the controller 11. The operation of one embodiment of the present invention will be described below with reference to FIG.

Prior to the inspection of the controller 11, the inspection content editing section 18 is used to create the inspection procedure file 14, the response message file 16, and the inspection command file 17.

For example, when the inspection command file 17 is created, an inspection command group required to cover all the models of the controller 11 to be inspected is stored.
The memory is stored in an order that is not related to the inspection procedure. And to identify each check command from each other,
A command label is attached to each inspection command. The waiting time for returning the response message is also stored in the field 33.

The same applies to the creation of the response message file 16, a plurality of response messages corresponding to all of the inspection commands are stored in random order, and a message label for identification is added.

On the other hand, the inspection procedure file 14 is created according to the inspection contents of the controller 11 to be inspected.

In this preparation, for each of the inspection procedures ordered by the numerical value of the field 50, the inspection command to be sent to the controller 11 is stored as a command label, and the returned response message is stored as a message label. That is, in the inspection procedure file 14, both the numerical value that is the command label and the numerical value that is the message label are stored in association with each of the numerical values that indicate the order of the inspection procedure.

By the above operation, each file 14, 16,
When the preparation of 17 is completed, the inspection becomes possible, and the controller 11 to be inspected is bidirectionally connected to the operation determination unit 12 by a wireless communication line.

The procedure conversion unit 15 uses the inspection procedure file 14
The command label “1” whose inspection procedure is “1” in field 50 is read and the command label “1” is converted into an inspection command by referring to the inspection command file 17. The inspection command converted at this time is
This is a system start-up command for instructing initialization of the controller 11 (step S11). This command and data indicating the waiting time are sent to the operation determination unit 12.

The operation judging section 12 sends this inspection command to the controller 11 (procedure f1 in FIG. 7) and judges whether or not the response message is returned from the controller 11 within the waiting time. When the response message is not returned within the waiting time, the fact is sent to the display unit 13 and the display unit 13 displays a malfunction (steps S12, S13, S18).

On the other hand, the procedure conversion unit 15 reads the message label "1" corresponding to the inspection procedure "1" and refers to the response message file 16 to convert the message label "1" into a response message. Then, the converted response message is sent to the motion determination unit 12
Send to.

Therefore, when the response message is returned from the controller 11 within the waiting time (procedure f2), the operation determination unit 12 determines whether the response message sent from the procedure conversion unit 15 and the response message returned from the controller 11 are returned. Make a comparison. Then, the comparison result is sent to the display unit 13 (steps S14 and S15).

At this time, the display unit 13 displays that the correspondence to the inspection command at this time is defective only when the comparison result does not show a match (steps S16, S).
18).

Thereafter, the same operation is repeated corresponding to the inspection procedure "2" of the inspection procedure file 14, and the inspection command indicating the setting of the target temperature of all the channels is sent to the controller 11 (procedure f3). Further, a corresponding response message is returned from the controller 11 (procedure f
4). Then, the message label corresponding to the inspection procedure “2” is converted into a response message and compared with the response message from the controller 11.

These operations are repeated for all the inspection procedures in the inspection procedure file 14. Then, the inspection ends (step S17), and when no error occurs, the display unit 13 displays that the operation of the controller 11 is normal.

FIG. 6 shows the contents when the inspection procedure file 14 is different. The inspection procedure file 1 shown in FIG.
While 4 is a file that instructs standard inspection,
The inspection procedure file 14a is a file added with an inspection as to whether or not the temperature increase signal indicating the temperature increase of the control target (for example, the extruder) of the controller 11 is normally transmitted (illustrated in FIG. 6). In the range, the inspection procedure file 14a shows that the inspection items "8" and "12" have been added.

The inspection operation of the controller 11 by the inspection procedure file 14a is the same as the operation already described, and the number of inspection loops increases with the addition of inspection items.

The inspection procedure file 14a shown in FIG.
Is created by using the inspection content editing unit 18 to insert numerical data or move numerical data based on the file 14 shown in FIG.

That is, the inspection procedure file in which the inspection of the temperature rising signal of each control channel of the controller 11 is added is created by the extremely simple operation of editing the numerical data of 1 to 2 digits. This is the controller 1
The same applies to the case of creating the inspection procedure file when the specifications of No. 1 are different, and the creation of the inspection procedure file corresponding to the inspection content is a simple task.

As described above, in the present embodiment, since the configuration in which both the command label and the message label are shown as numerical values is used, the work of creating the inspection procedure file 14 can be simplified. ing.

The present invention is not limited to the above-described embodiment, and the controller 11 to be inspected has been described as having a configuration for controlling the temperature, but in the case of inspecting a controller for performing any other control. The same can be applied to.

For the inspection procedure file 14, 1
The case where two files are used has been described, but reference numeral 14
It is possible to configure the block to which a plurality of inspection procedure files are stored so that the command label and the message label of the inspection procedure file corresponding to the controller 11 to be inspected are guided to the procedure conversion unit 15. .

[0045]

According to the controller inspection device of the present invention, there are provided an inspection command file in which a plurality of inspection commands are identifiable by command labels and a response message file in which a plurality of response messages are identifiable by message labels. An inspection procedure file that stores each combination of an inspection command and a response message returned from the controller as a combination of a command label and a message label in order according to the inspection procedure is provided. Then, the procedure conversion unit obtains the inspection command and the response message from the command label and the message label indicated by the inspection procedure file, and causes the operation determination unit to inspect the controller using the inspection command and the response message. It is configured. Therefore, the change of the inspection content can be dealt with only by changing the description of the inspection procedure, so that it is possible to reduce the trouble of creating the data for the inspection. Also, when the inspection command or response message itself is changed, only the corresponding file needs to be changed, so it is possible to flexibly deal with changes in various data required for controller inspection. ing.
