Abstract

PURPOSE:To facilitate an easy movement of each device with the output of a typewriter and to attain the quick collection of information with low cost, by securing a sequential operation among devices and providing a sequence state information storing part and a typewriter interface function into each device together with a type writer connected to the outside of the device. CONSTITUTION:The information is transferred between devices 1 and 2 via an information transfer line 3. If a defective transfer state of information occurs under such conditions, the typewriters 4 and 5 are connected to both devices 1 and 2 respectively to give indications to deliver the sequence state information to both devices. As a result, the sequence state information on the device 1 is delivered to the typewriter 4 via a typewriter interface line 6. While the sequence state information on the device 2 is delivered to the typewriter 5 through a typewriter interface line 7 respectively. These sequence state information on both devices 1 and 2 delivered to both typewriters 4 and 5 are analyzed to study the reason for defective transfer of information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for collecting operating status information of devices that exchange information using the IEEE 488 protocol.

[Conventional technology]

If you want to know the operating status of a device that conventionally exchanges information using the IEEE 488 protocol, you can micro-trace using a logic analyzer or the like to measure the operating status at-
I was analyzing.

[Problems to be solved]

In the conventional system described above, when a failure occurs in the exchange of information between devices and an attempt is made to determine the cause, it is necessary to trace the microprogram of each device to find out its behavior. For this purpose, two expensive logic analyzers are required, which poses a problem in that the cause cannot be quickly investigated.

[Means for solving problems]

The present invention solves the above problems and is based on the IEEE
When information is exchanged between devices using the 488 protocol, each device performs sequential operation by microcontrol, and each device has a 7-sequence status information storage unit and a typewriter interface function, In response to an instruction from the typewriter, the sequence status information of each device is outputted to the typewriter.

〔Example〕

Next, an example thereof will be explained with reference to FIG.

FIG. 1 is a block diagram showing an embodiment of an information gathering method according to the present invention.

In the figure, 1 and 2 are devices for transmitting and receiving information, 3 is an information transmitting and receiving line, 4 and 5 are typewriters (TTY), and 6.
7 is a typewriter interface line.

Next, its operation will be explained. The device 1 and the device 2 exchange information through an information exchange line 3.

If an information exchange failure occurs in such a state, typewriters 4 and 5 are connected to device 1 and device 2, respectively, and sequence status information is sent from typewriters 4 and 5 to each connected device (not shown). The sequence state information of the fruiting device 1 is output to the typewriter 4 through the typewriter interface line 6, and the sequence state information of the device 2 is output to the typewriter 5 through the typewriter interface line 7. Typewriter 4.
The sequence status information between device 1 and device 2 outputted in step 5 is analyzed to determine the cause of the information exchange failure.

〔Effect of the invention〕

As explained above, according to the information collection method of the present invention, the device is operated in sequence, the device is provided with a sequence status information storage section and a typewriter interface function, and a typewriter is connected to the outside. Since the movement of each device can be easily determined based on the output of the typewriter, information can be collected quickly and at low cost.

Claims (1)

[Claims] When transmitting and receiving information between devices using the IEEE 488 protocol, each device performs sequential operation by microcontrol, and each device has a sequence status information storage unit and a typewriter interface function, and receives and receives information from the typewriter. An information gathering method characterized in that the typewriter is configured to output sequence status information of each device according to an instruction.
