Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial application field The present invention relates to, for example, ON of energization from a plurality of output terminals,
The present invention relates to a timer device used for adjusting the inside temperature of an automatic soldering furnace, the sealing temperature of a packaging device by heat sealing, and other temperature by OFF control.

(B) Conventional technology Conventionally, as the timer device of the above example, for example,
There is an apparatus described in Japanese Patent No. 60-8204.

That is, it has an execution mode and a setting mode switching means,
This is a timer device that performs output setting for a plurality of output means by operating a key switch.

However, the above-described conventional apparatus has the following problems.

In other words, after setting ON and OFF output to the output terminals as a plurality of output stages under the setting mode described above,
Whether the execution mode according to the output setting is achieved or not is determined by actually driving the timer (in the case of a one-cycle 24-hour timer, the output setting is checked in a short time because it is not known unless the timer is driven for 24 hours). Had a problem that could not be done.

(C) Problems to be Solved by the Invention The present invention provides a unique mode means or the like for setting the mode mode to the debug mode, so that it is possible to immediately determine whether or not the execution mode is as set in the output setting, and furthermore, it is in a visible state. It is an object of the present invention to provide a timer device that can be checked by using a timer.

(D) Means for Solving the Problems The present invention provides a first display for displaying a time value, a second display for visually displaying a control output corresponding to a plurality of output means, and a mode mode of a debug mode. Mode means for setting, up and down keys for increasing and decreasing the time value, and time value of the first display based on manual ON operation of the up and down keys in the debug mode in the mode means. , And control means for controlling the second display to a visible display for turning on and off the second display in an output state corresponding to the time value.

(E) Effects of the Invention According to the present invention, the mode mode of the apparatus is set to the debug mode (detecting and correcting an error in a debug, program, or system) by the above-mentioned mode means, and the up key or the down key is set. When the key is manually turned on, the control means, for example, the CPU is operated to sequentially display the time value on the first display in a step-up display or a step-down display.
In the output state corresponding to the time value of the display unit, the second display unit illuminates and extinguishes the ON / OFF status of the control output, and turns it off to display a visual indication. Compared with the conventional device that checks with the timer output, whether or not the execution mode is the same as the output setting under the debug mode described above can be immediately and reliably checked by visual confirmation with a visual display. Further, there is an effect that this check can be executed by using the second display for displaying the control output, and this is extremely effective for a timer device which is multifunctional and complicated.

(F) Embodiment of the Invention One embodiment of the present invention will be described below in detail with reference to the drawings.

The drawing shows a rotary timer (cam timer). In FIG. 1, the rotary timer 20 includes an operation unit 21 and a display unit.
22 are disposed on the same surface of a single housing 23, and a lid 24 that covers the surface of the operation unit 21 so as to be able to open and close is attached.

The display unit 22 includes a three-digit seven-segment time value display 25 as a first display for displaying time values such as a current time and a set time and an error message, and a time range of hours, minutes, and seconds. Display range indicator 26
, ON, OFF, setting display 27 that displays various setting contents of ON, OFF, and multi (here, the control output is operated twice or more in one cycle), time range, cycle time, decimal point position, and batch count A setting item display 28 for displaying common items such as values, all clears, and time adjustments in alphabets, and a time chart, individual operation patterns for each control output, and other individual items in numbers from 0 to 7; A current value display 29 that lights up when the above-mentioned time value display 25 is displaying a current value, and a setting value display 30 that lights up when the above-mentioned time value display 25 is displaying a set value, Each of the display segments 31 of 1 to 16 corresponding to the number of a plurality of output terminals of the output unit 49 (see FIG. 2) described later, for example, 16 lines.
And a control output display 32 as a second display for turning on and off the control output, and a timer adjustment display for turning on when a value other than 0% is set to a specific common item of the setting item display 28. Table 33
And an operation indicator 34 that lights up as an output monitor while the timer is operating, and a three-bank structure bank indicator 35 that lights up and displays the bank being executed (bank, a memory block).

The operation unit 21 is provided with a first mode changeover switch 36 for switching between a run mode (RUN) and a setting mode (PROG).
And a second mode changeover switch 37 for switching between a common item (COM) and an individual item (SEP) of setting items, and switching between a start mode (START) and a debug mode (DEBUG) which are executed according to a program for which input has been established. A third mode changeover switch 38 as a mode means, a back key 39 used for confirming the individual item setting contents and common item setting contents programmed for each control output, and for operating the control output twice or more in one cycle. Multi key 40 to be used and up key to advance the time value by the time value display 25
41 and the down key to step back the time value by the time value display 25
48 and an enter key 43 used when registering a set value.

FIG. 2 shows a control circuit of the rotary timer 20, and the CPU 50 has a function of writing the output time and the output program of the ON output and the OFF output input from the operation unit 21 via the input interface 44 to the RAM 45.

In addition, it has a function of creating a current time by counting clocks generated by the clock clock generator 47 in accordance with a program written in the ROM 46.

The CPU 50 compares the current time with the ON output time or the OFF output time stored in the RAM 45 depending on the setting,
When the two times match, an ON output or an OFF output is output to the relay of the corresponding output terminal of the output unit 49 via the output interface 48, and the current output display on the display unit 22 is updated.

Further, the CPU 50 has a function of instructing the display unit 22 to display the time to be set, the current time, and the output mode when the output program is input from the operation unit 21.

The RAM 45 has a storage capacity necessary to store at least two or more combinations of the ON output and the OFF output and the set times corresponding thereto. More specifically, the rotary timer of this embodiment has 16 output terminals in its output section 49, and the RAM 45 stores mutually different output programs output from each output terminal.

When the third mode changeover switch 38 is switched to the debug mode, the up key 41,
The change of the time value of the time value display 25 based on the manual ON operation of the down key 42 and the display control of the control output display 32 corresponding to this time value are performed by the CPU 50 described above.

The operation of the rotary timer thus configured will be described with reference to the flowchart of FIG.

To set the rotary timer to the debug mode (a mode in which the output value is simulated by manually moving the time value forward and backward), the first mode switch 36 is switched to the RUN side in FIG. The mode changeover switch 38 is switched to the DEBUG side in FIG.

The second mode switch 37 may be on either the COM side or the SEP side.

By the changeover of the switches 36 and 38 described above, the rotary timer enters the debug mode, and the CPU 50 controls the drive of the time value display 25 in the display unit 22 so that the display on the display 25 is initialized to “0”. And the initial value “0”
Is displayed on the control output display 32.

In a first step 51, the CPU 50 determines whether or not one of the up key 41 and the down key 42 has been manually turned on. If any of the above keys 41 and 42 has been turned on, the CPU 50 proceeds to the next step. Move to the second step 52.

In the second step 52, the CPU 50 determines whether the keys 41 and 42 that have already been manually turned on are the up key 41 or the down key 4.
Determine if it is 2. That is, it is determined whether the debugging is performed by the step-up process or the debugging is performed by the backward process. If the up key 41 is turned on, the process proceeds to the next third step 53.

In the third step 53, the CPU 50 sets the time value display 25 to +
One step forward control is performed. Since this +1 is the minimum setting unit of the rotary timer, for example, +0.1 sec, the time value display 25
Are sequentially advanced in the order of 0.0, 0.1, 0.2, 0.3.

Next, in a fourth step 54, the CPU 50 determines whether or not the down key 42 has been turned ON. If the down key 42 has not been turned ON, the CPU 50 continues the above-described increment of 0.1 sec.

On the other hand, if the down key 42 is turned on, the process proceeds to the next fifth step 55, where the CPU 50
Processes the step rate at double speed. For example, the speed is increased by 10 times.

For this reason, the time value display 25 indicates 10
In increments of 1.0 sec, the steps are sequentially advanced in the order of 1,2,3,4 ...

Next, in a sixth step 56, the CPU 50 sets the control output display 32
Is driven and the output state corresponding to the time value of the time value display 25 is changed to a total of 16 display segments shown in FIG.
31 ... is turned on and off.

For this reason, the programmer can clearly see whether the display segments 31 are turned on or off by determining whether or not the execution mode is the execution mode according to the program for which the output setting has been made in advance in the debug mode state, and You can check in a short time.

When the CPU 50 determines that the down key 42 has been turned ON in the above-described second step 52, the process proceeds to the next seventh step 57.

In this seventh step 57, the CPU 50 sets the time value display 25 to-
One step backward control is performed. Since -1 is the minimum setting unit of the rotary timer, for example, -0.1 sec, the time value display 25
Are sequentially decremented to 00.0, 99.9, 99.8, 99.7...

Next, in an eighth step 58, the CPU 50 determines whether or not the up key 41 has been turned on. When the up key 41 has not been turned on, the CPU 50 continues the above-described retreat at every 0.1 sec.

On the other hand, if the up key 41 has been turned ON, the process proceeds to the next ninth step 59, where the CPU 50
Processes the walking rate twice as fast. For example, it is assumed that the walking speed is -10 times as fast.

For this reason, the time value display 25 indicates 10
In steps of 1.0 sec, which are doubled, the steps are sequentially decremented to 99, 98, 97, 96.

Next, in a sixth step 56, the CPU 50 sets the control output display 32
Is driven and the output state corresponding to the time value of the time value display 25 is changed to a total of 16 display segments shown in FIG.
31 ... is turned on and off.

For this reason, the programmer can clearly see whether the display segments 31 are turned on or off by determining whether or not the execution mode is the execution mode according to the program for which the output setting has been made in advance in the debug mode state, and There is an effect that the user can check within a short time.

Thus, the up key 41 or down key
By manually turning on 42, the control output correlation check and program check can be performed in a slow state (for example, in the minimum setting unit of stepping or retreating state). By turning on the up key 41 following the down key 42, a correlation check of the control output and a program check can be performed in a still state (for example, a 10 times double speed state).

In correspondence between the configuration of the present invention and the above-described embodiment, the execution mode and setting mode switching means of the present invention may be configured as follows.
In the same manner, the output means corresponds to the output section 49 having a plurality of output terminals, the key switches correspond to various keys 39 to 43, and the first display indicates the time value. Although the second display corresponds to the display 25, the second display corresponds to the control output display 32, the mode means corresponds to the third mode changeover switch 38, and the control means corresponds to the CPU 50. It is not limited only to the configuration of the above embodiment.
