Abstract

PURPOSE:To easily set an optimum on sequence control as a set data, by constituting in such a way that a display data during display is rewritten as a new set data instantly with a data write means. CONSTITUTION:When a start key is depressed and the operation is started in the mode other than a program, the display contents of a display section 7 make line display during high speed refresh based on the information stored in a user RAM11. When a TIM (timer designation) key is depressed in this state, an interruption program discriminates this TIM key, distinguishes all the displays 7 and waits for the designation of number of the timer. When the number of timer is designated, this number and an elapsed data are displayed on the display 7 via a keyboard control IC15 via a CPU6. When an R/W key is depressed with the numeric keys depressed, the numerical key data is read and a new set data is written in an area corresponding to the timer number of the RAM11 and the data during monitor is rewritten.

The program is always in the E-iUN state, and at this time, the display content on the display section 7 is as shown in FIG. As described above, the timer control is performed by generating a timer signal T8 of 100m5 from the power supply frequency from the power supply unit 81C shown in FIG. Rin? Let it be. This program runs as described above (every 100 mS, so the timer fIilIm can be executed). Programming key 2t: The program that runs when pressed is the interrupt program and the three program modes mentioned above every 100 mS. The timer data is stored in the specified area 1 of the user RA) Jtll as shown in Figure 5.
It is written in a 2-byte area fixed at 1A,
'Setting data' is taken and stored.Then, the C

'! The special program lnl:l adds +1 to the count value every 100 m5, writes and stores this value again, and sails. This allows timer elapsed data to be stored.

After adding the 100m5 special program to the designated area of the timer working area 16A, the added value, for example, TKDN shown in FIG. A comparison process is performed to see if they match, and if they match, a flag FA on the software is set to notify that the main program is VC. Therefore, the main program will be forced to perform time-up processing using this flag. If the start input condition for the timer disappears or the reset condition is input, naturally this flag FA is cleared, and the memory of the timer working area 16A is also cleared by 100''.
In the sequence system @ device of the present invention, multiple timers can be specified (C), and these distinctions can be made using the software (・
The flag Fb is set only for the timer when the input conditions are met and the timer becomes valid due to the main program.
The 10 grams of 10 grams are monitored and the working area of the 5 timers that should be outputted is valid, specifically, it corresponds to the number of the valid timer, and only the working area is added, and the timer without sliding electricity and the input conditions are not collected. The flag FB and working area corresponding to the number of Natsuna timer are immediately set to "o".
Therefore, it is possible to control sequence 14 with the value of the timer set as described above.
'+1 <% Timer information is configured to be stored in two areas: a specific area 11A of the user RAM 1i and a working area 16A provided in the L' stem l+AI 16, and the working area 16A side is stored in an addition method. The present invention is characterized in that the progress data of this working area is displayed by a display means, thereby enabling a monitoring function. That is, the monitor function in the present invention is to monitor the main program and interrupt program when the start key (18 for the first time) is pressed in a mode other than the program mode, for example, in the test mode mentioned above.

The 100 mB program runs independently, and the main program refreshes and displays a false line on display s7, as shown in Figure 4, to monitor the operation status. In this state, when the aforementioned T/M key is pressed down, the interrupt program determines this T/I4 key, turns off the display 7, and lights up the T/M key with built-in LED. , and then waits for the timer number to be specified. The above-mentioned TIM key and numerical keys are referred to as monitor switching means. When the numerical key, for example “1#” is pressed, the interrupt program is set to 10.
If you set the timer〇@+t, K=Utah function to 10 grams of 0mE+, set F'C to F15, which tells you to start the function.

Address the area r corresponding to the designated number of the timer from the timer working area 16A as a progress data storage area, and if you press 1tls-6 "1", the first 3 in the working area 16 Bai) TK
The progress data 4I consisting of Dl is stored in the display buffer 16B of display data provided in the system RArvH6 along with the designated # of the timer.
9 to the keyboard controller Ct5, the keyboard controller C15 sends the data to the display item 7 (see Figure 7) based on the data in the self-display buffer 16B. ), the first and second digits are blank (lights off), the third digit is the timer designation #r, and the fourth to sixth digits are the progress data. ) In the figure, timer 1 is 5.
This display shows the monitor display after 1 second has passed.
The process continues for a time of m5, and when 5.2 seconds have elapsed, the elapsed time fif is displayed on the monitor as shown in the figure, and this is repeated thereafter. In addition, in the present invention ((3) 9 as shown in figure
9. The decimal point is displayed until 9 seconds, and when it does not reach 100 seconds, the decimal point goes out as shown in the mountain diagram. From then on, until 999 seconds, the 1 timer activation input condition disappears or the reset condition is applied, and the display continues as an integer. It performs display. After reaching the maximum time of 999 seconds, addition of the elapsed data of the working area is also stopped and that state is maintained. Therefore 999
The monitor display continues in the second state, but it goes without saying that the branch is configured as it is in terms of operation.
In addition, in all of Kimoto's inventions, a display is also provided when the time is up. In other words, in a 100mB special program, if the progress data matches the setting data, or if the progress data is larger than the setting data, (61
) As shown in the figure, a time-up warning means 19 such as a decimal point is lit at the lowest digit, that is, the sixth digit, to further improve the monitoring function. In addition, if a specified timer number 1 is being monitored, or if the input conditions for that timer are not met and monitoring is performed in a de-energized state, or if a timer reset input is applied, etc. Begin to show.

The progress data is displayed as 10α0#, and when the timer is energized, it is layered to distinguish it from the state in which addition is displayed.In the Kimoto invention, during the monitor display, for example, when the timer 1 is displayed on the monitor, the numeric keys are pressed. When you press the key "0" manually, as shown in Figure 8), the - sign of the timer is displayed at the 3rd and fourth digit, and the % numerical key "01" and other digits are blank (unlit). Furthermore, when you press two numeric keys along 20", the screen shown in the figure ('b) is displayed, and when you press the 3-digit numeric key, you can R/W.
When the key (read/write key) is pressed, the interrupt program reads the 3-digit key data, excluding the timer number, from the display buffer 16B in the save area of the display data I to be sent to the keyboard control Ic, and immediately It is possible to write new 3-digit setting data in the area corresponding to the timer number IC of the user EAMz, and it is also possible to write data to 11 while monitoring. From that point on, this setting data will be used as the basis. Configure so that i processing continues.

As mentioned above, if the numeric key is pressed for four or more digits in succession, the fourth digit will be displayed. TIK In the present invention, the R/
The display data being displayed can be immediately rewritten as new setting data by a write operation of data writing means such as the W key. The principle is the same as described above, when the R/W key is pressed, the interrupt program sends the display buffer γ16B.
Therefore, the progress data can be immediately sent to the user RAM 11 as new setting data. When such a function is provided, as shown in FIG.
0, and when the other object 21 is controlled to be transported when it reaches point A, it is possible to control the transport to point A using a timer. In mode, set the timer setting value to a large value Ln[TA', operate it in the adjustment mode described above, and display the state on the timer monitor after 20 kilograms of objects are sent. When the object 20 reaches point A, press the R/W key.
The monitor display value TA at that time is set to 5 as the new setting data.
1 recorded, the object 20Fi is accurately A from that point on.
It is possible to control the conveyance of other objects 21 at a certain point. After adjusting the set values in the adjustment mode, when the mode is switched to the execution mode, accurate control is performed at the human point. Furthermore, 5i! In the case of line mode, it is necessary to prevent the user from accidentally giving the setting value.
Even if you press the R/W key on the
M11 is guarded against writing. Therefore, in the present invention, monitor operation excludes program mode. Test, ti! This is possible in the execution mode, and the setting data can only be rewritten in the test and adjustment mode.

In the setting data rewriting described above, after pressing the %R/W key, the monitor display is performed again. During monitor operation, to stop the monitor I function and return to the normal operating state, press the L/N (-main) key. The line display will be displayed again on the display 7 as shown in Figure 4, and the normal In one embodiment of the present invention, the timer monitoring operation has been described in detail, but in addition to the timer monitoring operation, the counter and internal output Monitoring is also possible. As shown in Figures 5 and 6, the counter is also equipped with dedicated areas 11B and 16C in the user RAM 11 and system RAM 16, just like the tires, and the monitoring methods and operations such as data rewriting are almost the same. . The difference is that the counter calculation process is done in the main program, and the data setting data can be rewritten with the timer, while the decimal point can be specified.

For example, only integer specifications are required. Also, <a) in Figure 10
As shown in the figure, if the counter does not count up to the set value, a count-up warning means such as a decimal point is lit on the lowest digit of the display section, similar to the timer. In Figure 10), counter number 5 counts up when the count value is 10 times [7 takotora meaning reading]. After the count-up decimal point lights up, the activation input condition for the counter disappears.
Or reset 7) If the condition is applied [7 is lzJ%, the lowest decimal point remains unchanged and the maximum! The count is displayed up to 999 times. If the activation input condition 2 disappears as described above, the counter value does not increase and the counter value immediately before the activation input condition disappears is displayed. When the reset condition is applied, the count value will display "000' as shown in Figure 10 (b), similar to the timer. 8. Next, the internal output monitor will be described. Output refers to a sequence in which multiple inputs are specified by Ic, AND or OR stop, in order to reduce the number of fins as much as possible when programming a sequence shown in Figure 11 (elL)). 1
Replace it with a set of internal outputs tL/-1,
This internal output is used as an input condition in other wines, and is output to an output key or output terminal.The internal output is designated as an internal output, and it is specified in program mode and other than the program. To monitor in other modes, press the 2-digit Z key as described above. To monitor internal output, press the Z key after movement in a mode other than program mode. This can be done by pressing two digits of the numeric key, and the input conditions for the internal output are met.In other words, in the excited state, the decimal point 19 lights up in the lowest digit as shown in Fig. 12), and the input conditions are not met. In this case, the decimal point in the least significant digit disappears. If b is used to specify internal force, the decimal point will not be lit, but only the internal output will be lit as shown in (b). In monitoring internal output, data rewriting is performed by 'fxIA', and monitoring of internal power is performed by the main program. timer, counter.

Each internal output monitor has a built-in LED.
Since the monitor display is performed on the display with the , CNT, and Z keys lit, it is easy to distinguish what is being monitored, so the timer is displayed one after another.

Even if the counter and internal output monitor operations are repeated, the above monitor display can be reliably performed.

In addition, in the present invention, 'J! Although the display part is a 6-digit LED display in the 2-embodiment, a liquid crystal display or the like may be applied, and a display element with a display position of 1 digit is not limited to the embodiment, and the present invention It is easy to imagine that various modifications and applications can be considered for the system RA.
Area configuration, size, and various data configurations such as M and Knee 4'-RAM! l! It is not intended to be limited to the examples.

As described above, according to the present invention, during the monitor operation,
! ! While celebrating the display value displayed on the monitor by the display means, it is possible to instantly rewrite the displayed data as new setting data by simply writing the data writing means provided on the main body. By configuring this, it is possible to easily determine the best data for sequence control as the t-setting data, which not only improves the accuracy of V-sequence control, but also allows data to be rewritten many times during operation. Because it is possible to switch to program mode and stop operation, there is no need to perform data *V etc. in the state of switching to program mode, and i * u is very easy;! In addition, while the monitor is operating, the numeric keys,
The data rewriting key allows data to be rewritten at will with simple key operations, which has the effect of improving operability and handling.
