Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a control device that controls an object by combining temperature and time, and is particularly useful when checking a set program or during a trial run check at a factory. The present invention relates to a program adjuster that can shorten the display of parameters used.

(Prior Art) Traditionally, the settings of the program controller have been confirmed by pressing the monitor key continuously to display and check the display data stored in the memory. Alternatively, the system is configured to check whether the desired control is being executed by actually driving the vehicle.

That is, as shown in FIG.
When 7 is operated, each set value is displayed on the 5V 26 provided on the front panel 21 of the program controller 20, the step number is displayed on the step 23, and the set time is displayed on the timer 24. , the setting value is set using the slide key 28 in the water direction and the up/down keys 29 and 3.
It is configured to be set using three setting keys: 0.

Further, in order to check the setting contents, by pressing the write/next key 31, the set temperature and set time at each step can be visually checked.

Further, while the program controller 20 is in operation, the setting item display section 22a and the setting time display section 22b of the display section 22 are displayed, and the operation status is displayed on the operation confirmation display section 22c. It has become so.

(Problem to be solved by the invention) However, since the program controller controls the object by combining temperature and time, it is naturally necessary to set the temperature and time parameters before operation. .

These parameters are normally set using a numeric keypad or up/down keys 29, 30, but when the number of program steps is large, a considerable number of key operations are required, and there is a considerable possibility of malfunction.

Therefore, it is necessary to thoroughly check the settings before operating the program controller 20.

Therefore, although confirmation is normally made by pressing a monitor key on the program controller 20, there is a possibility that the check may be overlooked if there are many steps due to the visual check.

It is also possible to check by actually operating the program controller 20, but this method has the disadvantage that it takes too much time.

Therefore, setting many patterns requires a considerable number of key operations, and setting errors are likely to occur.

Further, in order to check the setting contents, by pressing the light/neck key 31, it is possible to visually check the set temperature and set time for each step, but there is a large possibility that the number of steps may be misjudged.

In this way, the conventional method of checking the settings of a program controller is a visual check, which can lead to oversights and cause malfunctions, or it takes too much time to check, which impairs operability. There was a problem.

This invention has been made in order to solve the above-mentioned problems, and its purpose is to display the control parameters stored in the storage means of the program controller in a shorter time than the basic operating time so that they can be displayed on the display means. To provide a program controller that can improve the efficiency of checking the settings of the program controller by displaying the parameters and quickly and accurately checking the set control parameters. be.

(Problems to be Solved by the Invention) In order to solve the above-mentioned problems, the present invention provides a storage means for storing a plurality of control parameters displayed from a display means by operating a key input means, and a storage means for storing a plurality of control parameters displayed on a display means by operating a key input means. and a control means for controlling the input control parameters according to the basic operating time based on the reference clock of the timer and displaying the control parameters from the display means, A test run mode key outputs a test run command signal to the control means; When a test run command signal is input from the test run mode key, the basic operation time L is advanced and the above display is performed. The present invention is characterized by comprising: basic operation time changing means for displaying control parameters stored in the storage means from the means.

(Function) According to the controller of the present invention having the above configuration, there is a test run mode key provided in the key input means and outputs a test run command signal to the control means, and a test run mode key that is linked to the control means and allows the test run to be performed from the test run mode key. When the command signal is input, the basic operation time change means displays the control parameters stored in the storage means from the display means at the 9th point of the basic operation time. Since the configuration is such that the settings of the program controller can be checked in a short time simply by operating the mode key, malfunctions due to complicated key operations are prevented, and checking of the settings of the program controller is made more efficient. become.

(Explanation of Examples) Hereinafter, one embodiment of the present invention will be described based on the drawings.
