Abstract

PURPOSE:To remarkably increase a monitor function visually, by switching the monitor display of a timer in two stages as 0.1sec each and in the unit of second and displaying data on a display means. CONSTITUTION:When a specified key as a timer monitor switching means and a numeric key for timer number designation are depressed, an elapsed data is stored in a system RAM16 with the designation number of a timer, transmitted to a keyboard control IC15 via a CPU9 and displayed on a display 7. In this case, even if the data setting of the timer is set with an integer without fraction at a program mode, when the elapsed data is smaller than a predetermined constant TM in a system ROM10, display is performed so that the timer elapsed value is progressed at each 0.1. On the other hand, if the data is coincident with the constant TM or exceeds the constant, the elapsed value is displayed in the unit of 1sec. Thus, the elapsed value is displayed in a short cycle for the section with small elapsed value and the monitor display is switched in a longer cycle for the section with a large elapsed value.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sequence control device, and particularly to one having a timer monitoring function.

Conventionally, in order to further improve the operability and handleability of the sequence control device, there are certain things that can be done to improve the operability and handleability, such as input/output status during operation, execution line during parallel operation, timer, etc. 2iζ In particular, regarding the timer monitor, the timer display should be 2 digits as shown in Figure 1, and in the case of a long time I timer, the time base such as Q, 1 second, 1 second, 60 seconds, etc. should be displayed using LEDs, etc. The elapsed value being displayed was determined from the relationship between this time base and the displayed value on the display unit. The display section of the timer and the display section of the time base (unit) are often provided at separate positions when determining elapsed values.

There are disadvantages such as not being able to make instantaneous decisions.Also, with such a configuration, the larger the time base, the more
Of course, if the display value of the timer display part does not change and the status is displayed all the time, the concept of monitor processing will be weakened. If you want to see the progress of the race, you must monitor the timer's display value every minute.
When considering the function as a monitor, there are many problems.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, an object of the present invention is to instantly determine the elapsed value of the timer in a V-ken control unit equipped with a timer monitoring function, and to effectively monitor the progress of the elapsed value. The objective is to provide a device that can be displayed visually and greatly improve the monitor function.

That is, the present invention divides the elapsed value of the timer into a certain period consisting of
The timer monitor display is switched to two stages, and the timer display is displayed in two stages, such that the timer is displayed as if it is progressing every 0.1 seconds, and after the interval is exceeded, it is displayed in 1-second intervals. This is a characteristic feature.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. Second
In the figure, 1 is the main body of the V-can control lid of the present invention, and 2

is an output terminal, 6 is an output relay, and n7 is a display section as a display means for performing monitor display in the present invention, which is controlled by a keyboard operator C (described later) and is a light emitting diode capable of displaying 6 digits. , 17 is a power switch φ.The control structure of the sequence control device of the present invention will be explained based on the block diagram of FIG. Reference numeral 8 denotes a power supply section into which various voltages are supplied t1. This is a system ROM that records the processing procedures of various functions as a central processing unit (hereinafter referred to as CPU) that mainly performs 9d logic operations and a 10#i sequence control device. Reference numerals 1 and 1 designate readable and writable user RAMs in which contents of sequence circuits preset by the programming key 2 are stored. 12 is an input section to which the input terminal 4 is connected, and 13 is an output section to which the output terminal 5 is connected. Reference numeral 14 has the function of attaching the various keys 2 for programming mentioned above, detecting the electrical signals of these various keys, sending interrupt number 14 to the CPU 9, and transmitting the signals of the different keys to the CPU 9 as key manual data. A keyboard controller 015 accepts display data from the CPU 9 and performs all controls such as display operations on the display unit 7.
It is a program setting section equipped with. Also, the above C! Inside the PU9, there is a system RAM1 that can be freely read and written.
6 is built-in and false.

The present invention having the above configuration will be explained in detail.

Turn on the power switch 17, switch the function changeover key 3t to the "Putagram" mode (position P in the figure) shown in FIG. 2, and press the various programming keys 2 provided in the program setting section 14, for example.

When programming based on the V-ken diagram shown in Figure 1114, all program contents are stored in the user RAM described above.
11. As shown in the sequence diagram in Figure 4 (A
A single piece of logic starting from an input designation such as ND or OR and ending with an output designation is called a line, but after programming as described above, the -function switch key can be pressed in any direction other than "Program". For example, ``Medicine'' (E in Figure 2)
position) and press the start key (18 in the figure), the V-can control device of the present invention repeatedly performs a high-speed duff refresh between the first line-in 00 and the final line shown in Figure 4 VC from 00 to END. , when the input condition is met and false, the output is output to the output terminal, and when the input condition is not met, the output to the output terminal is turned off.In this state, the display contents of the display section 7 are First, the main points of the present invention and the processing of the timer to be performed will be explained by performing line display during high-speed refresh as shown in FIG.

Although the sequence using the timer is shown in Figure 4,
The timer control unit 8 shown in Fig. 3 generates a 100m8 timer signal T8 from the power supply frequency, and the CPU 9 constantly detects this signal, gives top priority when receiving the signal, and executes a special program in the V stem ROM. Let it be 9y. This program, as described above, is linked for each team, so it is possible to control the timer.

Immediately, the timer data that is not set in the program mode is written to the designated area (T6D1) of the specific area 11A of the user RAM 11 shown in Figure 6 and is stored as the "setting data". ing. And the system RAM 16 built into the CPU 9 is "OO" at the start of operation? ! 3? and shown in Figure 7 -t
The #regular area of this system RAM 16 is allocated as the I-timer working area 16A, and the 100 m
B's special program increases count value every 100m8.
This will be discussed by writing and storing the value again without adding 1.

This allows timer elapsed data to be stored. The program in the system ROM 11 is the 10 mentioned above.
0mB special program.

It consists of three types: a main program that is refreshed at high speed, and an interrupt program that runs when the programming key is pressed. 100m above
8 special programs are in working area 1 for timer.
After adding to the specified area of 6A, "11T after that addition"
For example, TKDl shown in the ag7 diagram is user RAM11.
The corresponding configuration data in, for example, the TSDI 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 the main program of this fact. Therefore, the main program performs time-up processing using this flag and obtains 1. If the start input condition of the timer disappears or the reset condition is input, the flag FA
is cleared 1, and the timer working area 1
The memory of dA can also be cleared to 00#.In the V-ken control device of the present invention, multiple timers can be specified at the same time.
Working areas for AM and timer are allocated, and all control between them is performed by flags on software. Among the benefits of such timer processing, the monitor function of the timer will be explained. When the start key (18 in FIG. 2) is pressed in a mode other than the program mode, for example, in the "execute" mode, the high-speed refresh line is displayed as shown in FIG. 5, as described above, and the system enters the operating state. When the user presses the T, M keys as the timer monitor switching means 20 shown in FIG. 2 and the numeric key 2C for specifying the timer number, for example "T', in the normal state, the timer is set to the special program of the interrupt program -!IrIQoms. The number "1" and a flag indicating the start of the monitor Jllfl! are set.The program of 100m5 determines this flag and the timer number, and searches for an address from the timer working elite 16A.

If you do not press ``1'', the first 3 pies) 'I' K
The progress data consisting of D 1 is stored together with the designated number of the timer in the V stem RAM 1.4 in the front and back bags 716B that store the display data of pitches and hits.A detailed description of the data editing method will be omitted. ) When the data is sent to the keyboard controller 015 via CP 9, the keyboard controller 015 displays the data in the first and second digits on the display N57 as shown in FIG. Prank (lights out).

The timer designation number is displayed in the 3rd digit and the progress data is displayed in the 4th to 6th digits. 5) The figure shows a monitor display when timer 1 has elapsed for 41 seconds.This display continues for a time of tooms, and 5.
When 2 seconds have elapsed, the elapsed value is displayed on the monitor at 5.2 seconds as shown in the figure, and this is repeated t thereafter. The present invention
Even if you set the timer data in the program mode to an integer value without a decimal point (a decimal point can be specified), the elapsed data may be smaller than the constant TM predetermined in Vstem]l'tOM10. In this case, the timer elapsed value is unconditionally shown as if it progresses every α1 seconds, and the constant TM
If it matches or exceeds , the elapsed value is displayed in 1-second intervals.

Although l[ of the constant TM may be determined arbitrarily, in the embodiment of the present invention, specifically, one display means is provided, and all display sections 7 are capable of displaying the elapsed value of the timer. Fake it by setting it to a value that can be displayed every α1 second within the maximum number of digits. In other words, if the maximum number of digits that can be displayed is 3 digits, the decimal point will be displayed every α1 second up to 999 seconds, and if the maximum number of digits is 4 digits, the decimal point will be displayed every 11 seconds up to Fi999.9 seconds.W TMF of chopsticks
i100 seconds, and the latter TM is set to 1000 seconds.

In the embodiment of the present invention, the maximum number of digits that can be displayed for b″C′ is 3.
(C) As shown in the figure, the 99.9 second speed is displayed as a decimal point, and when it reaches 100 seconds, the decimal point goes off as shown in the table display IIi function diagram, and from then on, the timer is displayed until 999 seconds. An integer is displayed every second unless the activation input condition disappears or a reset condition is applied. After reaching the maximum time of 999 seconds, the marking elite's elapsed data also stops being added, and the monitor continues to display %999 seconds, and the system is configured in such a way that it causes some problems in operation. . In addition, the present invention also displays the time CH/7'WP, and as shown in the figure (e), the time-up alarm means 19, such as a decimal point, is lit at the lowest digit, that is, the 6th digit.
, -'(I!) One timer, one number monitor, not specified in I!.

Or, if the input conditions for the timer are not satisfied and monitoring is performed in the de-energized state, or if an input is applied to reset the timer, etc., as shown in figure (f)
0.0'' is displayed and 1 is distinguished from the state in which addition is displayed while the timer is energized.

As described above, according to the present invention, even if the timer setting data is not set as an integer without a decimal point in the program mode, the timer monitor display is unconditionally set to %0.1 until a certain elapsed time is reached. Since the information is displayed on the display means as if it were progressing every second, the concept of monitor processing, which constantly displays the status of the operation at high speed, can be more strongly visually appealed to the user. ．． ．． ．． The r-sequence control equipment is now working properly and can upgrade the monitor function, thereby contributing to improving product value. Further narrowing down the scope of the present invention, the elapsed value is displayed at a 1-second wheel position after the above-mentioned certain elapsed time is reached, so the elapsed value is displayed at a 0.1-second wheel position. When there is no requirement for relatively large setting data, the display of elapsed values can be visually appealing, such as when the elapsed values are small.

By displaying the elapsed value in short cycles and automatically switching the monitor display with long cycle V in the first section of the elapsed time, the monitor function is visually improved and practicality is greatly improved. We can offer you something very good.
