`

`
`
`The present invention pertains to an electronic device, and in particular to an electronic
`
`device that has a data transmission function and that is able to monitor the data transmission
`status.
`
`Prior Art
`
`In recent years, many types of electronic devices, such as personal computers,
`programmable controllers, various types of terminal devices, and NC devices, have been
`provided with a data transmission function in order to connect to another electronic device.
`
`Hitherto, a device known as a so-called protocol analyzer has been utilized to know the
`data transmission status of these electronic devices. When measuring, a protocol analyzer is
`connected to the circuit and used, and it is possible to display the data on the circuit and the
`status of modem control signals.
`
`Problems the Invention Is to Solve
`
`Nevertheless, a communication status monitoring system that uses the above-mentioned
`protocol analyzer has the following sorts of problems.
`
` A protocol analyzer must be used while directly connected to the circuit of the
`electronic device, so the protocol analyzer must be provided, and time and effort are required to
`connect it to the circuit.
`
` A protocol analyzer needs a display device, but the electronic device usually has a
`display device too. The fact that the monitor means cannot utilize the display device of the
`electronic device is uneconomical.
`
` A data communication status monitor is needed by various different users, both large
`and small. However, with conventional systems, a small user without a protocol analyzer cannot
`monitor the data communication status.
`
`In view of these problems, it is therefore the object of the present invention to provide an
`electronic device that can monitor the electronic device's transmission/reception data and the
`control status of circuit control signals using the electronic device itself.
`
`Configuration of the Invention
`Means for Solving the Problems
`
`In order to achieve the above-mentioned object, in the present invention an electronic
`device that has a data transmission function is provided with: an instruction unit that specifies a
`circuit and instructs display of the transmission status of the specified circuit, a current status
`detection unit that detects the current status of transmission control signals for the circuit
`specified by the instruction unit, a control signal status display editing unit that edits the current
`status of transmission control signals detected by the detection unit into display data, a
`transmission/reception data display editing unit that edits transmission/reception data for the
`circuit specified by the aforementioned instruction unit into display data, and a display
`processing unit that displays display data edited by the aforementioned control signal status
`editing unit and/or the aforementioned transmission/reception data display editing unit on a
`display device.
`
`Operation
`
`An electronic device in accordance with the present invention has a built-in monitor
`means which utilizes a part of members that perform the basic functions of the electronic device.
`
`
`

`
`Kyocera PX 1023_8
`
`

`

`
`
`Along with carrying out the basic functions of the electronic device, the [monitor means]
`displays transmission/reception data and/or the control signal status on the display device, based
`on instructions from the instruction unit.
`
`Embodiments
`
`Below, embodiments of the present invention shall be described with reference to
`drawings.
`
`FIG. 1 is a block diagram showing the first embodiment of the present invention.
`
`In the drawing, 1 is a modem, 2 is a transmission interface, 3 is a transmission control
`unit, 4 is a transmission/reception processing unit, 5 is internal circuitry, 6 is a reception data
`buffer, and 7 is a transmission data buffer. Also, 8 is a keyboard, 9 is a display circuit number
`storage unit, 10 is a display output control storage unit, 11 is a circuit control signal status
`accumulation unit acting as a current status detection unit, and 12 is a control signal status
`display editing unit. In addition, 13 is a transmission/reception data editing unit, 14 is a display
`processing unit, and 15 is a display device (CRT).
`
`The modem 1, transmission interface 2, transmission control unit 3,
`transmission/reception processing unit 4, reception data buffer 5 [sic], and transmission data
`buffer 6 [sic] perform data transmission between another electronic device (not shown in the
`drawing) and the internal circuitry 5 according to the RS-232 standard. These members are not
`different from publicly known members.
`
`Specifically, when the internal circuitry 5, which is for performing the basic tasks of the
`electronic device, wants to transmit data to another electronic device, it informs the
`transmission/reception processing unit 4 to that effect, and sends data for transmission to a
`predetermined part of the transmission data buffer 7. The transmission/reception processing unit
`4 specifies a circuit to that electronic device and sends this data to the transmission control unit
`3.
`The transmission control unit 3 reads the transmission interface 2 control signals, such as
`
`DTR (data terminal ready) output, data set ready input, RTS (request to send output), CTS
`(request to send input) for the transmission interface 2, and sends the aforementioned
`transmission data to the other electronic device via the predetermined transmission interface 2
`and modem 1 at a predetermined timing.
`
`Furthermore, after transmitting data, when the data "ACK" is sent back from the other
`electronic device as reception completed notification, that concludes data transmission, but if the
`resend request "NAK" is sent back, the transmission/reception processing unit 4 again transmits
`the same data to that other electronic device. "ACK" and "NAK" data is temporarily stored as
`data in the reception data buffer 6 connected to the circuit.
`
`Meanwhile, if data is transmitted from the other electronic device, the transmission
`control unit 3 sends received data to the transmission/reception processing unit 4, and the
`transmission/reception processing unit 4 stores this data in a predetermined reception data buffer.
`
`The keyboard 8 can perform the usual key operations. Also, here, it forms a part of the
`instruction unit, and can specify a circuit, and instruct display output of that circuit's
`transmission/reception data and the control signal status with the signal "1."
`
`The circuit control signal status accumulation means 11 reads the status of the circuit
`control signal for the transmission interface 2 when the display output control storage unit 10 is
`"1." The read status is accumulated in memory. The accumulation system is configured by
`providing in advance memories corresponding to the "ON" and "OFF" status for each type of
`
`
`
`3
`
`Kyocera PX 1023_9
`
`

`

`
`
`control signal, and counting the statuses when those signals appear in these memories. Therefore,
`data indicating the current status of the control signals can be obtained when the content of each
`memory is read in order.
`
`The control signal status display editing unit 12 reads the accumulated data of the circuit
`control signal accumulation unit 11 at each fixed time interval (for example, every 0.1 seconds),
`and edits the current status of the circuit control signals as line-unit data. This editing unit 12
`initializes the memory counts after reading the accumulated data in the memory of the circuit
`control signal status accumulation unit 11.
`
`The transmission/reception data display editing unit 13 reads the contents of the
`aforementioned reception data buffer 6 or the transmission data buffer 7 upon completion of
`transmission or reception for the specified circuit, and edits this as data for display in line units.
`
`The display processing unit 14 inputs the edited data of both of the aforementioned
`editing units 12 and 13, normalizes the character codes for editing, such as character codes for
`transmission control such as DTR and DSR and colons (:), and performs a predetermined display
`on the screen of the display device 15 so that data reception timing, etc. can easily be checked.
`The display content is described in detail in FIG. 2.
`
`The transmission control unit 3, reception data buffer 6, transmission data buffer 7,
`keyboard 8, and display device 15 are elements that are essentially mandatory for the electronic
`device itself, but in this example these elements are in an arrangement allowing use as the
`monitor means that is referred to in this example.
`
`FIG. 2 shows the screen status of the display device 15. A screen A is the portion
`displaying data edited by the transmission/reception data display editing unit 13, and a screen B
`is the portion displaying data edited by the control signal status display editing unit 12. The
`screen A is a scrolling screen on which lines move up over time, and the screen B is a semi-fixed
`screen on which the two lines do not move.
`
`To analyze the screen A, "T" indicates transmission and "R" indicates reception. Codes
`such as EQ, Ak, Sx, etc. are abbreviations of ISO control characters; for example, Ak indicates
`ACK and Nk indicates NAK. This screen is configured so that while "1" is specified at the
`display output control storage unit 10, lines of the sequential data stored by the reception data
`buffer 6 and transmission data buffer 7 for the circuit specified at the display circuit number
`storage unit 9 are displayed while moving up.
`
`Meanwhile, at the screen B, circuit control signals DTR, DSR, etc. are placed in columns
`corresponding to "ON" and "OFF" lines, and if the current status of a circuit control signal is
`"ON," that position is displayed as an illuminated point. Here, the aforementioned control signal
`status editing unit 12 reads the accumulated processing count (memory) of the aforementioned
`circuit control signal status accumulation unit 11 every 0.1 seconds, so even if the predetermined
`control signal is "ON" for a time somewhat shorter than 0.1 seconds, for example, this status can
`be displayed as an illuminated point for at least a 0.1 second interval.
`
`Using this display, an operator can see the flow of transmission/reception data using the
`screen A, and can see the status of the control signals at those times using the screen B.
`
`Furthermore, in addition to the above-mentioned display 15 of course it is possible to
`connect a printer and save these screen statuses as time charts.
`
`Thus, it is not necessary for the operator to specially provide a protocol analyzer, and it is
`possible to know the transmission status when appropriate if necessary.
`
`FIG. 3 shows a block diagram of another embodiment.

`

`
`
`In this embodiment, a display mode control storage unit 16 is added to the
`
`aforementioned embodiment, and the screen of the display device 15 can be divided and
`displayed as the transmission/reception data display shown in FIG. 4 or as the circuit control
`signal status display shown in FIG. 5. Selection of a display screen is performed using the
`keyboard 8.
`
`The display examples shown in FIG. 4 and FIG. 5 merely show one example of mode
`selection corresponding to FIG. 2. Various settings for mode division are possible, depending on
`the details of the electronic device. For example, it is also possible to make enable programming
`two or many display modes with the control signal status editing unit 12 according to the use
`status of the electronic device, and to properly use these modes according to the use status.
`
`Effect of the Invention
`
`As described above, according to the present invention, by adding a monitor means with
`a simple configuration to the electronic device, it becomes possible to easily, swiftly, and
`reliably monitor the transmission status using the electronic device itself.
