[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a programmable display for displaying and controlling the state of a device of a target system to be controlled in a control system.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional control system 101 controls various target systems 102 such as a belt conveyor type automatic assembling machine.
PLC 103) and a control system 101 connected to the PLC 103 via a serial cable 104.
And a programmable display device 105 serving as a human machine interface (HMI) are widely used.

In many cases, the programmable display 105 is arranged near the target system 102. The programmable display 105 acquires the status of the device 102a of the target system 102 and the status of the PLC 103 from the PLC 103, and outputs the status to the programmable display 105. The screen is displayed on a built-in display (not shown). Further, the programmable display 105 includes a touch panel (not shown) arranged on the screen of the display, and transmits a control instruction to the PLC 103 to the PLC 103 in response to an operation on the touch panel by an operator. 102a
Control the state of the.

On the other hand, the PLC 103 repeatedly executes a control program such as a ladder program at a predetermined cycle (scan time), for example, so that the device 1
02a, and controls the state of the device 102a in accordance with instructions from the programmable display 105 and signals from the device 102a.

Although FIG. 3 shows only two devices 102a for convenience of explanation, in general, many devices 102a are included in the target system 102.
... are provided. In recent years, as devices 102a of the target system 102, not only devices directly related to the manufacture of products and control of the target system 102, such as motors, valves, or switches themselves, but also cameras and illuminations for capturing images near the site. In many cases, devices that are not directly related to manufacturing or control, such as devices for collecting / processing data on manufacturing management, air conditioning, or manufacturing management, are included, and the types of the devices 102a are often diverse.

In the above-described programmable display device 105, an operator usually operates while viewing the display screen of the display. Then, the programmable display device 105
Detects an abnormality or the like based on a signal from the device 102a, and notifies an operator of an alarm by displaying a blink on a display or a buzzer sound.

[0007]

As described above, in the conventional programmable display device 105, feedback from the machine to be controlled (the target system 102) is reported to the operator by a display and a buzzer sound. Was. However, the notification by the buzzer sound is completely useless in a loud working environment. Therefore, the operator had to look at the display to ensure that the operator received feedback from the machine, particularly an alarm of an abnormality that occurred in a place that was not visible from the outside of the machine.

Here, the programmable display device 105
There is a handy type. In many cases, the hand-held programmable display 105 is operated by an operator while holding the hand and looking at the machine without looking at the display screen. For example, the operator can use a touch panel or keys to move the belt conveyor little by little while watching the machine near the belt conveyor.

However, if the conventional hand-held programmable display 105 is operated without looking at the display in a loud working environment, the operator operates without receiving any feedback from the machine.

As described above, in the conventional programmable display device 105, the feedback from the target system 102 is notified to the operator by the display on the display and the buzzer sound. However, in a work environment in which the operator cannot confirm the display and cannot hear the buzzer sound due to noise, even important information such as an alarm cannot be notified to the operator, causing an erroneous operation.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a programmable display device which can notify an operator of an alarm or the like by stimulating a tactile sense by vibration or the like. It is in.

In order to solve the above-mentioned problems, a programmable display according to the present invention has a programmable display having display means for displaying a state of a device and input means for receiving an operation on the device. The device is provided with a notifying means for stimulating an operator's tactile sense according to the state of the device.

According to the above arrangement, the programmable display includes, in addition to the display means and the input means, a notifying means for stimulating the tactile sensation of the operator according to the state of the device to be controlled.

Therefore, according to the programmable display, information such as an alarm according to the state of the device can be notified to the operator by stimulating the tactile sense by the notification means. Here, the output generated by the notification means only needs to be able to stimulate the tactile sensation of the operator, and may be, for example, vibration by a vibration motor or electrical stimulation by a weak current.

Therefore, even in a work environment in which the operator cannot confirm the display means (display) and does not hear a buzzer sound or the like due to noise, the operator is notified of important information such as an alarm by a stimulus to tactile sense other than visual and auditory senses. It becomes possible. As a result, the operator can operate the input means (touch panel, key / switch, etc.) without receiving any feedback even while looking at the device to be operated, that is, in the state in which the operator keeps his eyes off the display means. Is eliminated, and occurrence of erroneous operation can be prevented.

For example, the programmable display device prompts the operator to confirm an abnormality or the like occurring in the device by first stimulating the tactile sensation by the notification means to prompt the operator to confirm the display means. Information can be fed back. Thus, the operator can perform an accurate operation according to the information fed back from the device via the input unit.

In order to solve the above problems, the programmable display device of the present invention is further provided such that the notifying means is provided on a grip portion for an operator to grip the main body including the display means and the input means. It is characterized by having.

According to the above configuration, in the programmable display device, the notifying means is provided on a grip for the operator to grip the main body including the display means and the input means. Therefore, the notification means can surely give a tactile stimulus to the operator's hand holding the main body. Note that the notification means can be provided inside or on the surface of the grip portion.

In order to solve the above problems, the programmable display device of the present invention is further characterized in that the notifying means is provided separately from a main body including the display means and the input means. I have.

According to the above configuration, in the programmable display device, the notification means is provided separately from the main body including the display means and the input means. Therefore, the notification means can be provided separately from the main body and in a shape that easily stimulates the tactile sensation of the operator. Therefore, it is possible to reliably give the operator a tactile stimulus that is an output of the notification means. Further, since it is not necessary to consider giving a stimulus to the operator by the notification means in the design of the main body, it is possible to flexibly design the main body and the notification means.

Specifically, for example, a notifying means is embedded in a wristband (notifying member) worn by the operator, and a control signal is transmitted from the main body of the programmable display device by wire or wirelessly to stimulate the tactile sensation of the operator to generate an alarm. Etc. can be notified.

In order to solve the above problem, the programmable display device of the present invention is further characterized in that the notifying means controls the intensity of the vibration when stimulating the tactile sensation of the operator by the vibration.

According to the above configuration, unlike the case of notifying only by the presence or absence of the vibration, the strength of the vibration can be controlled, so that the operator can be notified of information such as danger and the degree of emergency. As a result, the operator can perform more accurate operations via the input means according to the information fed back from the device.

In order to solve the above-mentioned problems, the programmable display device of the present invention further comprises a mode in which the notifying means includes a mode for controlling the intensity of vibration, a mode for controlling only the presence or absence of vibration, and a mode for not vibrating. It is characterized by being switchable.

According to the above configuration, since the notification means can switch between the modes by, for example, an operator's operation or a prior setting, it is possible to notify information such as danger or the degree of emergency due to the strength of vibration. The programmable display device having the same configuration can be used for an application in which the notification is desirable, an application in which it is desirable to notify only by the presence or absence of vibration, and an application in which notification by vibration is unnecessary.

An input / output memory, a D / A converter, an A / D converter, and the like are provided. The I / O unit 23 and the I / O control IF circuit 24 are detachable so that the I / O unit 23 can be replaced and the I / O unit 23 connectable to the desired device 2b can be used. There may be.

In addition, the handy programmable display 5H further includes a key / switch 18b, a vibration motor 31, and a vibration motor controller 32.

The vibration motor controller 32 has a CP
The vibration motor 31 is controlled according to an instruction from U11. The key / switch 18b is controlled by the operation input controller 19 together with the touch panel 18a, and is used for an input operation by an operator.

Here, the above-mentioned SRAM 12 and FEP
The ROM 13 stores, as programs and data for operating the programmable display 5, screen data, display / control system programs, communication protocol data, communication programs, device drivers, protocol conversion programs, ladder programs, ladder processing programs, and the like. Is stored. Note that these data / programs may be stored in the programmable display 5 in advance, or may be read from a recording medium (for example, a CD-ROM or the like) on which the program is recorded and stored. Further, these data / programs may be distributed and installed on the programmable display 5 via, for example, the serial cable 4, the local area network 6, or another communication path.

The operation screen of the programmable display 5 is configured as screen data in which marks as image blocks are arranged on a base screen such as a background screen. In particular,
The screen data is configured by combining a tag indicating a correspondence between an area on the screen and an address of a device corresponding to display or input in the area. Therefore, the screen data includes data of a mark as a base screen and an image block, a processing instruction word (tag) given to each mark, and the like.

The above-described marks are prepared in advance as imaged basic parts such as touch switches, lamps, various displays, and the like. In addition, as a mark, a moving image function unit in which a desired moving image function is set in a rectangular area set at a desired position in order to express a dynamic change of a switch, a numerical display, or the like at an arbitrary position on a screen. Is also included.

The tag is created for each event to be executed on the base screen. Basically, the file number of the base screen on which the display control operation is to be executed, and the tag is executed on the base screen. An event name for specifying an operation to be performed and reference information including one or a plurality of data referred to for each execution event are provided as a set. For example,
In the case of a display tag that displays a part graphic corresponding to the content of a predetermined device address in a predetermined screen area (display coordinate range), the reference information includes a display coordinate range (XY), a device address, If the part figure is a switch,
A file number to be referred to at the time of display, such as a graphic file indicating N and a graphic file indicating OFF, is included. When the tag is an input tag, the reference information includes a valid input coordinate range (XY) and a device address to which an input result is written.

Further, the display / control system program refers to the screen data to read the device 2a.
2b... Are acquired and displayed on the display 15 or in response to an input on the touch panel 18.
This is a program for controlling the state of... 2b.

Then, in the handy type programmable display 5H, the display / control system program is as follows:
When it is determined that an alarm needs to be issued based on the states of the acquired devices 2a... 2b, a message is blinked on the display 15 via the display controller 17 and the vibration motor 31 is transmitted via the vibration motor controller 32 at the same time. Vibrates.

Thus, the hand-held programmable display 5H causes the vibration motor 31 to vibrate inside the grip 5a, and the vibration can make the operator sense the occurrence of an alarm. Therefore, in addition to the conventional display of the display 15 and the notification to the visual and auditory sense of the operator by the conventional display 15 and the buzzer sound, the change in the signal from the target system 2 can be notified by using the human tactile sense by vibration. Therefore, the operator can view the device to be operated as it is, that is, the display 1
Even when the user keeps his / her eyes away from 5, it is possible to receive notification of the occurrence of the trigger.

For example, the hand-held programmable display 5H prompts the operator to confirm an abnormality or the like that has occurred in the target system 2 by the vibration of the vibration motor 31 and prompts the operator to confirm the display 15. Detailed information can be fed back. Of course, the buzzer sound may be emitted at the same time as the vibration motor 31 is vibrated by the occurrence of the trigger.

The trigger for causing the vibration motor 31 to vibrate can be set at the timing of switching the screen to the screen displaying the alarm information, but is not limited to this.

The information notified by the vibration of the vibration motor 31 is not limited to the abnormality of the target system 2. For example, the handy programmable display 5H is
Upon detecting that the backlight of the display 15 has run out, the operator can be notified by the vibration of the vibration motor 31. The hand-held programmable display 5H
Then, it is difficult to know whether the power is off or the backlight is off but the operation input is possible. For this reason, turning off the backlight of the display 15 has caused an erroneous operation.

Further, the vibration motor 31 can swing the grip portion 5a of the hand-held programmable display 5H in various vibration modes by the vibration motor controller 32. That is, the vibration motor 31 can carve a rhythm by adjusting the strength of vibration and the interval between ON and OFF. Therefore, the vibration motor 31 can output a plurality of types of alarms with respective vibrations. In addition,
Only the vibration by the vibration motor 31 can be performed without the display on the display 15 or the buzzer sound.

Hereinafter, an example of the configuration of the vibration motor controller 32 which can set the strength (the number of rotations, rotation, etc.) of the vibration motor 31 by software will be described with reference to FIGS. That is, the vibration motor controller 32 shown in FIG.
A circuit for operating the vibration motor 31 from the time when the instruction is given to the time when the OFF instruction is given, the latch circuit 32a holding the instruction from the CPU 11;
Transistor 3 that turns ON / OFF according to output Q of 2a
2b and a transistor 32c arranged between the vibration motor 31 and the power supply Vcc and driven by the transistor 32b. Further, resistors 32d and 32e are provided between the base of the transistor 32b and the output Q of the latch circuit 32a, and between the collector of the transistor 32b and the base of the transistor 32c, respectively.

In the above configuration, for example, when the CPU 11 sets the enable terminal E bar of the latch circuit 32a to the potential indicating the writing by writing to the address of the latch circuit 32a, the latch circuit 32a sets the C terminal at that time.
The value written from the PU 11 is held and held until the next write is instructed.

When this value indicates ON, transistors 32b and 32c are turned ON. As a result, the power supply voltage Vcc is applied to the vibration motor 31 and the vibration motor 31
Rotates. On the other hand, if the written value is OFF,
The transistors 32b and 32c are turned off, and the power supply voltage Vcc is not applied to the vibration motor 31. Therefore, the vibration motor 31 stops rotating.

In the above configuration, the vibration motor 31 is turned ON / O
The timing of FF is determined by the CPU 11 by the latch circuit 32a.
Can be determined at the timing of writing the value of ON / OFF to. Therefore, by controlling both timings by the CPU 11, the start / stop of the vibration of the vibration motor 31 can be controlled, and the vibration rotation can be controlled and the vibration can be patterned.

Further, when the CPU 11 instructs ON / OFF in a short cycle, the power supply voltage Vc is supplied to the vibration motor 31.
The duty ratio when applying c is PWM (Pulse Width).
Modulation) can be controlled. As a result, the number of rotations of the vibration motor 31 can be controlled, and vibration can be given strength.

As an example, when the CPU 11 controls the strength of the vibration motor 31 according to the length of the alarm signal AL input to the hand-held programmable display 5H, the CPU 11 outputs the alarm signal AL at a predetermined cycle. It is detected whether an abnormality is indicated (ON / OFF).

While the alarm signal AL is OFF (for example,
(at time t0), the CPU 11 turns on the latch circuit 32a.
The value of OFF is written without writing the value of. Thereby, the output Q of the latch circuit 32a becomes, as shown in FIG.
It remains OFF, and the vibration motor 31 is stopped.

On the other hand, when the CPU 11 detects that the alarm signal AL has been turned on (at time t1), the CPU 1
1 is written to the latch circuit 32a so that the output Q is turned on / off at a predetermined cycle and at the first duty ratio as shown in FIG. Accordingly, the vibration motor 31 vibrates at the weakest first strength.

Also, even if a predetermined period elapses,
If the alarm signal AL remains ON, the CPU 11
Is written to the latch circuit 32a at the time t2 so that the output Q is turned ON / OFF at the above cycle and at the second duty ratio larger than the first duty ratio as shown in FIG. . Thereby, the vibration motor 3
1 vibrates at a second strength higher than the first strength.

Further, in the case where the alarm signal AL remains ON even if the alarm signal AL vibrates at the second intensity for a predetermined period (t3
At this time, the CPU 11 controls the latch circuit 32a so that the output Q keeps on as shown in FIG. As a result, the vibration motor 31 vibrates at the strongest third strength.

When it is detected that the alarm signal AL has been turned off (at time t4), the CPU 11 controls the latch circuit 32a so that the output Q continues to be turned off as shown in FIG. Therefore, the vibration of the vibration motor 31 is stopped.

As described above, the CPU 11 can control the intensity of the vibration according to the length of the ON period of the alarm signal AL. As a result, even when the operator of the handy-type programmable display 5H cannot see the screen, for example, when he / she cannot take his / her eyes off the device 2a for control, danger or danger may occur due to the strength of vibration. The ratio of emergency can be transmitted by the intensity of vibration.

In the above description, the alarm signal AL is turned ON.
The case where the degree of abnormality is notified according to the period length and the CPU 11 controls the duty ratio of the output Q has been described, but as shown in FIG.
When the degree of abnormality is indicated by the combination of AL1, the CPU 11 may detect ON / OFF of both, and control the vibration intensity according to the combination of both. In this case, the output Q is changed from the time t10 to t14 shown in FIG.
9 and FIG.

By the way, in the above description, the case where the magnitude of vibration is controlled according to the degree of abnormality has been described as an example.
If the strength of the vibration can be controlled, three modes, that is, a mode in which no vibration is used, a mode in which only ON / OFF of the vibration is controlled, and a mode in which the strength of the vibration is controlled may be switched.

The above modes may be set in advance by, for example, a drawing editor for designing screen data stored in advance in the handy type programmable display 5H,
The screen data may be set so that the mode is changed according to the result of selection in the menu. In any case, if the mode can be switched, a handy programmable display device 5 capable of controlling the intensity of vibration is provided.
H can also be used for applications that do not require vibration intensity control.

In the above description, the case where the alarm signal AL (AL0 / AL1) indicating the degree of abnormality is determined has been described as an example. However, the present invention is not limited to this. For example, the CPU 11 may select any of the externally input signals as the alarm signal based on the screen data or the control program. In this case, since the alarm signal can be changed by the drawing editor or the program editor for designing the control program, it is possible to more flexibly adapt to each application. In addition to an external signal, the CPU 11 operates the hand-held programmable display 5H, and internal devices included in the hand-held programmable display 5H such as a timer.
Alternatively, the degree of the abnormality may be determined in accordance with the result of performing a predetermined operation (macro operation) on a signal, an operation, or an input from an internal device in advance, and the intensity of the vibration may be controlled. The method of determining the degree of abnormality according to which may be fixed. However, flexibility can be improved by setting the abnormality using the drawing editor or the program editor.

In the hand-held programmable display 5H, the vibration motor 31 is provided to cause the operator to sense the generation of the trigger by vibration. However, it is sufficient that the operator can stimulate the tactile sensation of the operator. It may be a stimulus.

In the hand-held programmable display 5H, the vibration motor 31 is incorporated in the grip 5a of the main body. However, it is sufficient that the tactile sensation of the operator can be stimulated. ,
A notification member separate from the main body may be provided. Then, a control signal may be transmitted from the main body of the hand-held programmable display 5H to the notification member by wire or wirelessly to stimulate the tactile sensation of the operator and notify the alarm, similarly to the vibration motor 31.

The hand-held programmable display 5H need not be connected to the control host computer 7 or another programmable display 5. further,
The hand-held programmable display 5H is a PLC 3
, And may control only the directly connected device 2b.

This is a configuration including a notification unit that stimulates the tactile sensation of the operator accordingly.

Therefore, according to the programmable display, information such as an alarm according to the state of the device can be notified to the operator by stimulating the tactile sense by the notification means.

Therefore, even in a work environment where the operator cannot confirm the display means (display) and does not hear a buzzer sound or the like due to noise, important information such as an alarm is notified to the operator by stimulus to tactile sense other than visual and auditory senses. The effect that it becomes possible is produced. As a result, the operator can operate the input means (touch panel, key / switch, etc.) without receiving any feedback even while looking at the device to be operated, that is, in the state in which the operator keeps his eyes off the display means. And the effect of preventing erroneous operation can be achieved.
