DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described as an external device connected to a program type display device, as shown in FIG.
A specific description will be given based on an example using C. An external device using a general-purpose or special-purpose computer or other control device, or a device for controlling the operation of various electric appliances in a home. It is needless to say that the same can be implemented in substantially the same manner. Further, the configuration of the programmable display device is also an example, and the configuration is not limited.

The programmable display device 22 includes a PLC 36
In addition, it is integrated into an operation console or the like of the target system 38, or is provided independently, and is used as an operation and a display panel for the target system 38. A setting or control operation is performed.

PLC for controlling target system 38
The circuit 36 has a function realized as a whole in the PLC 36, in which a circuit is unitized for each necessary function such as a CPU unit and a memory unit, and the units are connected in parallel so as to be able to increase or decrease as necessary. The configuration is substantially the same as that of the related art that can be changed.

The storage location of various information input / output to / from the target system 38 is controlled by passive components such as level gauges and limit switches provided on the target system 38 to be controlled or displayed, or relays and motors. Each active component is allocated on a memory unit, and a word device is specified for word data whose input / output is numerical value, and a bit device is specified for bit data such as on / off information. By preliminarily setting a device-specific device name such as “D100” for each device, necessary data is stored in the memory unit so that the storage location can be specified by designating the device name.

Therefore, by simply accessing the arbitrary word device or bit device in the memory unit by designating the device name from inside or outside the PLC 36, without knowing the actual address in the PLC 36,
The corresponding position of the target system 38 is controlled or data relating to the operating state thereof can be individually retrieved.

The programmable display device 22 has substantially the same configuration as the personal computer device, and includes a display control circuit 40 shown in FIG.
In addition, as shown in FIG. 3, the front surface of the display screen 28 of the display 24 is covered with a transparent touch panel 42 in a close contact state, and an instruction by a pressing operation on the touch panel 42 is fetched via a touch panel controller 44 to analyze the coordinates. During a test, various manual operations can be performed by a fingertip at the time of initial setting before starting operation of the entire system or during operation.

Here, in the programmable display device 22, as shown in FIG. 3, there is a base screen 46 whose display contents do not need to be changed, and a switch figure whose shape changes, blinks or changes color on the base screen 46. The functional part graphic 48 is designated and stored with one file number F for each required display unit.

On the other hand, as shown in FIG.
The processing instruction word W stored in advance in the processing instruction word W illustrated in FIG. 4A is read out intermittently every minute time, and the operation of the content specified by the event name N of each processing instruction word W is performed on the PLC 36 side. Display operation in which the part graphic changes in response to a change in the content of the bit device or word device on the PLC 36 side by sequentially executing the data from the state data memory 50b via the communication controller 51 while referring to the data retrieved from the device. Is performed.

That is, the basic structure of the processing instruction word W is as follows.
It is composed of a file number F of a base screen 46 on which a display control operation is to be executed, an event name N specifying the operation content to be executed on the base screen 46, and one or a plurality of data referred to for each execution event. Reference information r is provided as one set.

For example, the processing instruction word WT shown in FIG.
Is to make it possible to invert data at a predetermined bit position in the state data memory 50b in conjunction with a pressing operation on the touch panel 42. That is, the base screen 46
File name F1, event name N1 starting with, for example, "T" for specifying the operation of touch panel 42, touch panel 4
An input coordinate range XY where the input operation from No. 2 is valid and a bit position A where data should be rewritten in conjunction with the pressing operation of the touch panel 42 are provided.

Further, the processing instruction word WL shown in FIG.
In conjunction with the operation of the touch panel 42, a predetermined figure can be displayed at a corresponding position. That is,
A predetermined functional component graphic 48 can be displayed at a predetermined position on the base screen 46 in response to a change in a predetermined bit position in the state data memory 50b. For example, an event name N2 starting with "L" for specifying the display of the part graphic 48, a display coordinate range X / Y of the functional part graphic 48, a file number FL for specifying the part graphic to be called, and state data for referencing the part graphic at the time of display. A bit position A in the memory 52 is provided.

Therefore, as shown in FIG. 5A, the coordinate range XY
Processing instruction word W that matches
L1 · WT1 is set in the event data memory 50a. When the data at the bit position A in the state data memory 50b is "0", the PLC 36 turns off the switch contact by associating the data with the off state of the switch in advance. At the same time, the data FL of the component graphic corresponding to the OFF state of the switch is stored in the graphic memory 5.
0c, the coordinate range XY on the base screen 46
Expand and display.

Further, when the display location of the switch-shaped functional component graphic 48 on the touch panel 42 is pressed, the processing instruction word WT for the touch panel 42 is searched, and the touch panel 4
The presence / absence of a processing instruction word WT having, as reference information r, a range including the corresponding coordinates from the instruction coordinates made through the step 2 is determined.

For example, when one point in the coordinate range XY is pressed, the processing instruction word WT1 constructed as described above is pressed.
Therefore, as shown in FIG. 5B, the data value at the corresponding bit position A is inverted from “0” to “1”,
The corresponding switch contact is turned on by the PLC 36. At the same time, the processing instruction word WL1 determines that the reference bit has changed to “1”, reads data FL ′ corresponding to the ON state of the switch in the functional component graphic 48 from the graphics memory 50c, and reads the corresponding coordinate range X By displaying on Y, the switch-shaped functional component graphic 48 displayed on the display 24 is also changed from the off state to the on state.

The present invention is characterized in that a sound generating means is provided in addition to the above configuration, and a predetermined sound generating operation is enabled by using a processing instruction word. Here, the sound generating means has substantially the same configuration as the conventional one,
On the other hand, while storing a plurality of types of sound data by specifying a file name and a storage address on the audio data 0c, the sound data is read out to the sound generation unit 26 at a necessary time, and transmitted through a D / A converter provided in the sound generation unit 26. Thus, an audio signal corresponding to the audio data is reproduced, and the audio corresponding to the audio signal can be displayed through the speaker 56.

On the other hand, in addition to the general-purpose processing instruction words described above, a processing instruction word WS dedicated to sound processing shown in FIG. 4D is provided. The processing instruction word WS specifies the file number F1 of the base screen 46 and the display of the sound, for example, “S”.
, The file number FS for specifying the sound data to be called, the bit position A in the state data memory 50b for referencing the sound data at the time of display, and whether the sound is generated once in response to the reference bit A being on. , And display mode information M for determining whether to repeatedly display during the ON period.

Here, for example, the acoustic data FS to be displayed
While compressing and storing audio data having a content related to a switch operation such as "switch is turned on" in a predetermined format, the display mode information M is set to one sound generation, and the touch panel 42 described above is set. The processing instruction word WS1 in which the reference bit position A is made to coincide with the address that is turned on in conjunction with is stored in the event data memory 50a.

Then, the operation state is visually displayed by the change of the switch shape in conjunction with the ON operation of the switch described above, and at the same time, a sound indicating that the switch operation has been performed is generated, which appeals to hearing. Is displayed.

The sound displayed through the sound generator 26 is not limited to a human voice having a predetermined meaning, but may be a single sound such as a bell sound, a melody sound accompanied by a melody, or an animal sound. It can be carried out by appropriately changing the sound, artificial synthetic sound, and the like.

Further, instead of generating the sound in conjunction with the switch operation as described above, the occurrence of a predetermined event such as the timing of displaying an error message on the display screen 28 is monitored. In conjunction with the occurrence of an event, an acoustic display corresponding to the content of the event can be displayed. In that case, instead of displaying a fixed message, based on text data displayed on the display screen 28, the data content can also be displayed by voice synthesis.

The explanatory diagram shown in FIG. 6A shows another operation example of the processing instruction word for processing the operation on the touch panel 42 shown in FIG. 4B. Instead of performing a toggle operation in which the on / off state is reversed each time the switch is turned on, the on state is maintained during the switch on operation, but an inching operation that returns to the off state when the on operation is stopped is possible. Is what you do.

Further, a plurality of bits such as A, B and C are provided which are turned on and off in conjunction with the switch operation. Here, the bit position A is turned on corresponding to the period during which the switch is turned on, as in the case of FIG. 5, so that the switch position is displayed with reference to the bit position A or the robot arm is displayed. By making it possible to drive a device that is to perform such an inching operation, a predetermined operation can be continuously performed only during a pressing operation of the touch panel 42.

On the other hand, the bit position B is turned on for a predetermined short time in accordance with the switch on-start timing, and the bit position C is turned on for a predetermined short time in response to the switch off time.

Further, as sound data, in addition to the voice data a corresponding to the ON operation of the switch such as "the machine is dangerous during operation", a switch operation such as "the switch is turned on" is also performed. The voice data b indicating the start and the voice data c indicating the end of the switch operation such as “switch has been turned off” are stored in advance.

Then, the above-described audio data a is set at bit position A, the audio data b is set at bit position B, and the audio data c is set at bit position B.
Correspond to the bit position C, a plurality of types of voice display can be easily performed in response to one switch operation.

FIG. 6B shows still another embodiment. When the duration of the ON operation on the touch panel 42 is less than the set value τ, the bit position A indicating the operation time of the touch panel 42 is inverted. Furthermore, when the bit position A is not inverted, the bit position B indicating the start of the operation is not inverted. With this configuration, even if the switch is operated by mistake, unnecessary sound is prevented from being generated.
