BEST MODE FOR CARRYING OUT THE INVENTION An electronic device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

First, as a premise, in the electronic device 1 of the present embodiment, a plurality of operation modes are switched to each other to perform an operation according to each operation mode. Therefore, either the first operation mode or the second operation mode is performed. By setting this as the current operation mode, the operation according to the current operation mode thus set, that is, the operation according to the first operation mode or the second operation mode is performed. Further, it can transmit its own device ID to an external communication destination based on a predetermined communication protocol, and stores a first ID corresponding to the first operation mode and a second ID corresponding to the second operation mode. One of the two corresponding to the current operation mode is transmitted to the outside.

Therefore, by setting either the first operation mode or the second operation mode as the current operation mode, the corresponding device ID can be transmitted while performing the operation according to the current operation mode. As a result, even at the communication destination, the device ID
Based on the above, communication processing / communication control suitable for the operation of the electronic device in the current operation mode can be performed. That is, by changing the setting of the current operation mode of the electronic device, it is possible to flexibly change the purpose of communication, the function used for it, and the like, and it is possible to perform processing suitable for it even at the communication destination.

In the following description, the first operation mode is the normal operation mode for electronic equipment, and the second operation mode is the operation mode for testing or maintenance.
Corresponding to each, the first ID (ID1) is the device ID during normal operation, and the second ID (ID2) is the device ID during testing or maintenance. As an external communication destination, a personal computer or the like that can also be used as a communication destination during normal operation is assumed, and the personal computer or the like is used as an inspection device TST used for testing or maintenance, for example, as shown in FIG. It is described that the inspection system 50 is configured as a whole by connecting via the interface IF such as.

Of course, during normal operation, the interface can be configured in multiple stages and multiple connections, or can be an interface including a network such as the Internet, but these are also the simplest one-to-one connection of FIG. Therefore, the system of FIG. 2 will be described as a representative example.

Here, the above configuration and the test method using it will be described in detail below with reference to the processing (test) flow in the case of inspecting (testing) using the above-described inspection system 50.

As shown in FIG. 1, in this inspection system (test device) 50 and the test method using it, first, in the initial setting (S1), an EEPROM which is a non-volatile memory is mounted (S11), and then, , Its EEP
Predetermined address of ROM, that is, first ID (ID1)
The setting ID is written in the address for use (S12). The EEPROM in this case may also be used as a memory for downloading a program to be described later, or may be another one. The setting ID is an individual ID for each device corresponding to, for example, the manufacturing number, and is the first ID (ID1) here.

When the initial setting is completed (S1), the inspection (test: function test) is prepared (S2). In this inspection preparation (S2), first, as shown in FIG. 2, the inspection device (personal computer or the like) TST is connected (S21).

Here, in the electronic device 1 of the present embodiment, the operation mode at the time of activation can be determined based on the activation condition, and the activation condition includes the condition of key operation at power-on. Therefore, the start condition can be changed by changing the key operation when the power is turned on, and the operation mode at the start can be changed. Here, the power is turned on while the key is operated so as to be in the second operation mode, and the power is turned on (S22).
In the operation mode, the program is downloaded (S23) and the inspection preparation (S2) ends. At this point, the electronic device 1 has been completed as an electronic device for the time being, so that it is possible to proceed to the inspection (test: S3).

As described above, in the electronic device 1, the second
The operation mode is an operation mode indicating test or maintenance, and the second ID (ID2) is an apparatus ID for performing test or maintenance. That is, it is defined as usable as an operation mode and device ID when performing so-called testing or maintenance before shipment or during maintenance. Therefore, when the current operation mode is the second operation mode, the program executed in the first operation mode can be downloaded from the communication destination. Also,
This eliminates the need for the download function as the function in the first operation mode, so that the load of the execution program can be reduced except during the test or maintenance, and the program by the unnecessary and unauthorized download in the first operation mode can be saved. Rewriting can be prevented.

Here, the structure of the electronic device 1 that should be completed when the inspection preparation (S2) is completed will be summarized. In the electronic device 1 at this time, the first ID (ID1) and the predetermined second ID (ID
2) is stored, and the first ID (ID) and the second ID (ID
Any one of 2) can be selected and transmitted as the device ID (see FIG. 2), the ID to be written as the first ID (ID1) is input as the write ID from the outside, and the ID writing instruction is input from the outside. The write ID can be written accordingly.

That is, in the electronic device 1 at this time, both the first ID (ID1) and the second ID (ID2) can be read (transmitted) as the device ID, and the first ID (I
D1) can be rewritten. Therefore, if the first ID indicates an abnormal value due to unwritten or other reasons, it is possible to use the second ID (ID2) for the time being and proceed with the communication function and other tests in which the device ID should be used. Further, the first ID (ID1) is later rewritten to a valid ID.

Since the second ID is defined to be usable as a device ID at the time of so-called testing or maintenance before shipment or during maintenance, the second ID (ID2) is the read ID (communication ID10 in FIG. 2). When it is selected, the ID writing instruction is validated, and otherwise, it is invalidated. As a result, useless (illegal) ID writing can be prevented when the other than the second ID (the first ID) is selected.

Next, the operation mode and the read ID at the start of the inspection (test: S3) will be explained. Here, for the time being, the first operation mode and the first ID (ID
1).

As described above, in the electronic device 1, the first ID
Since either the first operation mode corresponding to or the second operation mode corresponding to the second ID can be set as the current operation mode, the read ID (communication ID) and the current operation mode are switched in association with each other. In this case, the start condition can be changed by changing the key operation when the power is turned on, and the operation mode and the read ID at the start can be changed. In addition to this, from the communication destination (here, a personal computer or the like: inspection device TST). The designated ID is received, and the operation mode and the read ID after the designated ID is received can be determined based on the received designated ID.

Therefore, here, first, the inspection device TS
By transmitting the first ID (ID1) from T as the designated ID, the operation mode and the read ID (communication ID) at the time of starting the inspection (test: S3) are the first operation mode and the first ID (ID1), respectively. To do. When this form is viewed from the communication destination (inspection device TST: personal computer, etc.) side, the operation mode of the electronic device 1 is changed (to the first operation mode) by transmitting the designated ID (here, first ID: ID1). Possible and changed device ID (first ID: I
D1) can be received from the electronic device 1. That is, as seen from the communication destination, the electronic device 1 is an electronic device that can flexibly change the function to be used by the designated ID and can send the device ID corresponding thereto.

First operation mode and first ID (ID1)
When the inspection (test: S3) is started in the selected state, first, the setting ID, that is, the first ID is read. In other words, the test target ID (test ID: communication I in FIG. 2)
As D), the first ID (ID1) is read (transmitted via the interface IF: S31).

Then, the read setting ID
It is determined whether or not (first ID: ID1) is an abnormal value (S
32). The setting ID is the individual ID for each device, as described above.
However, since the value corresponds to the manufacturing number and the like, if the writing is normally completed, the value is usually within a predetermined range. Therefore, a value that is close to what is called an indefinite state can be determined as an abnormal value.

When it is determined that the set ID is not an abnormal value (S32: No), a test for normal operation (test routine: test for first operation: first ID function test) is performed, and if there is an error (S351: Yes). ), It is dealt with (S352), and the problem (abnormality etc.) is analyzed or solved (S35).

On the other hand, when the setting ID is determined to be an abnormal value (S32: Yes), the fact (abnormality) is notified by, for example, displaying it on the monitor of the inspection device (PC or the like) TST. (S33), the designated ID is the second
By setting the ID (ID2), the second operation mode and the second ID are switched.

That is, the second ID (ID2) is the default I common to the devices (of the same model or version).
As D, a predetermined second ID corresponding to the transmitted second ID is transmitted as the device ID instead of the first ID (ID1).
Perform a functional test. As a result, even when the first ID to be read as the device ID shows an abnormal value due to other reasons such as unwritten, it is possible to proceed with the functional test defined as the second functional test.

In the second functional test in this case, the first functional test for testing the same function as the functional test performed when the transmitted first ID is determined to be a normal value.
Includes ID functional test. Therefore, even when the first ID to be read as the device ID shows an abnormal value due to unwritten or other reasons, the first ID functional test (test routine: first operation test: S35) is performed, and the first ID function test is performed later. 1 Problems that are discovered after rewriting the ID to a valid ID can be discovered ahead of time.

When the inspection (S3) is completed, it is judged whether or not there is an ID abnormality (S4), and if there is no abnormality (S4:
No), the inspection is completed and the product is shipped (S6).

On the other hand, when there is an ID abnormality (S4:
Yes), after the setting ID is written again (S5), the same inspection is performed again (flow shown in F10 of FIG. 1 to S3). That is, when there is an ID abnormality, the second
The second function test is performed by changing the operation mode and the second ID. Since the ID write function test (S5) of writing the write ID is included as part of the second function test,
When the first ID shows an abnormal value due to unwritten or other reasons, the first ID can be rewritten.

By the way, in this inspection system (test device) 50 (and the test method therefor), the first ID can be rewritten by the ID writing function test, but the second ID can be written as the writing ID. That is, since the first ID can be matched with the second ID, if the test on the second ID is completed before that, it is possible to test only the function of the reading (sending) system of the first ID, and the problem is found. In such a case, the problematic part can be easily isolated.

Further, as a matter of course, by the above-mentioned ID writing function test, as the writing ID to be originally written, for example, the individual ID corresponding to the manufacturing number or the like for each device can be written. Further, the steps from the writing of the second ID to the test may be performed after the end. That is, since the function test for the individual ID can be performed, for example, if the common function test with another device that can test the first ID in accordance with the second ID is completed, only the function unique to the individual ID is completed. It is possible to test, etc., and when a problem is found, it becomes easy to isolate the problem part.

As described above, in this inspection system (test device) 50 (and the test method therefor), the first
Both the ID (ID1) and the second ID (ID2) are the device I.
Read as D (can be sent) and have the first ID (ID
The electronic device 1 capable of rewriting 1) is set as a test target.
The electronic device 1 is caused to transmit a first ID (ID1) as a device ID, and it is determined whether the transmitted first ID (ID1) is a normal value or an abnormal value. Therefore, if the first ID (ID1) indicates an abnormal value due to unwritten data or another reason, then
For the time being, it is possible to use the second ID (ID2) to advance the communication function and other tests that should use the device ID, and later rewrite the first ID (ID1) to a valid ID.

In the conventional case, when the ID abnormality is detected, the setting ID is written (S1) in the initial setting (S1).
It was necessary to start over from 2) (flow indicated by F100 in FIG. 1). Further, in the above description, in the writing of the setting ID of the initial setting (S1) (S12), the conventional setting (of the individual ID) is performed. However, the ID abnormality occurs in the first inspection (test: S3). Even if there is, it can be rewritten and re-inspected, so the first setting ID is written (S1
2) can be omitted.

Similarly, writing the first setting ID (S
In 12), the common ID (default ID: second ID (ID2)) is written instead of the individual ID (first ID: ID1), and the test in the second operation mode (second functional test) is performed in the first inspection (S3). After performing the above step, the individual ID (first ID: ID1) may be written again as the set ID (S5), and the normal operation in the first operation mode may be inspected. In addition, individual ID (first ID: ID
1) has no functional meaning and is the second functional test.
If only the ID is sufficient, the retest can be omitted (F20 flow in FIG. 1).

In the above description, the first inspection (S
At the start of 3), the first operation mode and the first operation mode are temporarily set.
Although the ID is used, similarly to the above, first, the inspection is performed in the second operation mode and the second ID, and then the inspection in the first operation mode and the first ID, that is, the inspection for the normal (functional) operation is performed again. You can also do it.

Next, returning to the description of FIG. In the above example, the first operation mode is the normal operation mode of the electronic device 1, and the second operation mode is the operation mode for testing or maintenance.
(ID1) is the device ID during normal operation, and the second ID (ID
2) Device ID for testing or maintenance
And In this case, in the above example, the first ID (ID1)
Is stored in an EEPROM which is a rewritable memory, and the second ID (ID2) side is not specified,
Since it is a predetermined value, it may be fixed as a level signal by a clamp or the like in a logic circuit, or may be stored as a fixed value in a memory similar to the first ID. Further, in the above-mentioned example, the second ID side is set to the predetermined value, but it is possible to assume that rewriting is possible similarly to the first ID side.

Also, the external communication destination is assumed to be
Although the inspection device TST is composed of a personal computer or the like that can also be used as a communication destination during normal operation, if the electronic device 1 has a plurality (here, two) of device IDs and can transmit them selectively, the communication destination Then, since it is recognized as a plurality of devices (two devices) connected in multiple stages or in multiple stages by the same connection as a hub, it is possible to prepare by preparing a driver (a concept including hardware and software) corresponding to each ID. In the above example, the driver DRV1 in normal operation corresponding to the first ID (ID1) in the first operation mode and the driver DRV1 in test or maintenance corresponding to the second ID (ID2) in the second operation mode This can be dealt with by preparing a DRV2 (corresponding to the above-mentioned description, a special (during test) process such as download + corresponding to a process during normal operation).

In other words, as shown in FIG. 3, in the conventional electronic device 100, basically one device ID is provided for each device.
Since it has only (ID10), communication using different functions of the electronic device 100 cannot be performed, and even if a plurality of (two) drivers DRV1 and DRV2 are prepared on the communication destination side, the communication destination side Although it could not be handled unless it was installed or set up again each time, in the electronic device 1, since a plurality (two) of device IDs can be selectively used, a plurality of (two) drivers DRV1,
By preparing the DRV2, it is possible to deal with it without re-installing the driver.

In the example of the electronic device 1 described above, the driver DRV1 on the normal (function) side may not have a download function unnecessary for the user.
The load on the driver can be reduced (inevitably the capacity is also reduced), and the situation where the download function (wrong) operates due to careless operation by the user and an abnormality occurs is prevented. it can.

In this example, the driver DRV1 corresponds to the "normal operation (normal)" of the first ID, and the driver DRV2
The second ID is "maintenance (download etc.) + normal", but the driver DRV2 is only "maintenance (download etc.)" and the second ID (ID
For 2), driver DRV1 + driver DRV2
You may make it correspond with.

As described above, in the electronic device 1 of this embodiment, by setting either the first operation mode or the second operation mode as the current operation mode, the operation according to the set current operation mode is performed. , Is capable of transmitting its own device ID to an external communication destination based on a predetermined communication protocol, stores a first ID corresponding to the first operation mode and a second ID corresponding to the second operation mode, and stores these One of them, which corresponds to the current operation mode, is transmitted to the outside. Therefore, by setting either the first operation mode or the second operation mode as the current operation mode, the corresponding device ID can be transmitted while performing the operation according to the current operation mode.

As a result, even at the communication destination, the device ID
Based on the above, communication processing / communication control suitable for the operation of the electronic device in the current operation mode can be performed. That is, by changing the setting of the current operation mode of the electronic device, it is possible to flexibly change the purpose of communication, the function used for it, and the like, and it is possible to perform processing suitable for it even at the communication destination.

In the above example, the device IDs are used by distinguishing between the normal operation and the test operation, but in addition to this, communication (function, etc.) different for each model, series, and version is used. If so, it is possible to apply such as preparing a device ID in accordance with it. In addition, of course, other changes can be made as appropriate without departing from the scope of the present invention.
