Abstract

PROBLEM TO BE SOLVED: To simplify a parameter setting operation by substituting the changed numerical data for present numerical data stored in a memory when it is judged that the numerical data which are inputted as the set value of parameters to be changed are different from the numerical data which are presently set. SOLUTION: A comparison part 3 compares the data (present set value data) stored in a memory 2 with the changed set value data to judge whether both data are coincident with each other. A change/register part 4 substitutes the changed set value data for the present set value data stored in the memory 2 based on the signal received from the part 3 and showing that those compared set value data are different from each other. The part 4 also registers the substituted set value data as the new set value data. Thus, it is possible to omit the conventional operating procedure required for registration after the change of the numerical value and also to omit a conventional fixed waiting time when the numerical value are changed for various parameters. Therefore, the parameters can be set in a simple way and at a high speed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when changing the numerical values of various parameters, omits the operation procedure of registration (confirmation) required after changing the numerical values, and simplifies the parameter setting operation. Regarding the setting device.

[0002]

2. Description of the Related Art Conventionally, when changing the numerical values of various parameters with a temperature controller or the like, a "registration (confirmation)" procedure was required after the numerical values were changed. The technical meaning of this registration procedure is to store and hold the changed numerical value data in a non-volatile memory or the like. The parameters include proportional band, integral time, derivative time as control parameters, lower limit alarm value / upper limit alarm value, hysteresis of ON / OFF operation, heater burnout alarm set value, output specified value at input error, etc. . Now,
A specific operation for registering parameter numerical values is performed by pressing a registration key provided exclusively for setting registration. Depending on the format, pressing the shift key at the first digit (rightmost digit) of the set numerical value may replace the registration operation. In addition, there is also a method in which, when the parameter value is not changed continuously for a certain period of time, the parameter value is regarded as fixed and is automatically registered.

[0003]

In the conventional example, when changing the numerical values of various parameters, a registration operation of confirming the numerical values after changing the numerical values is necessary, or in order to automatically register. It is necessary to take a certain waiting time. In particular, when the parameter setting is performed through a remote operation means such as digital transmission or digital input from the outside, the operation procedure for registration and taking a certain waiting time will further affect the operation procedure. This causes problems such as troublesomeness and increase in registration time.

The problem to be solved by the present invention is to provide a parameter setting device which solves the above problems of the prior art and simplifies the parameter setting operation.

SUMMARY OF THE INVENTION According to the present invention, a memory for storing numerical data currently being set for a parameter; the numerical data input as a setting value to be changed for the parameter is equal to the numerical data currently being set. A comparing unit that determines whether the two numerical data are different from each other; when the two numerical data are determined to be different by the comparing unit, the current numerical data stored in the memory is replaced with the changed numerical data and the changed numerical data is updated. The configuration includes a change / registration unit that registers as a set value.

Here, the changed set value can be input via an attached operation means or can be input from the outside via a remote operation means. In the present invention, the comparison unit determines whether the numerical data input as the setting value to be changed of the parameter and the numerical data currently being set are equal or different. When it is determined that the two numerical data are different, the changing / registering unit replaces the current numerical data stored in the memory with the changed numerical data, and the changed numerical data is registered as a new set value.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a parameter setting device according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the functional arrangement of the embodiment.
In FIG. 1, 1 is a set value input key for inputting a new set value, 2 is a memory for storing the current set value data, 3 is a comparison unit, and 4 is a change / registration unit. The comparison unit 3 compares the stored data (current set value data) in the memory 2 with the changed set value data, and determines whether these are equal. The change / registration unit 4 stores the changed set value data stored in the memory 2 based on the difference determination signal from the comparison unit 3 that the current set value data is different from the changed set value data. And is registered (determined) as new set value data.

FIG. 2 is a front view of the front panel of the embodiment. On the front panel, a selection key 11, a shift key 12, a down key 13, and an up key 14 are arranged on the lower stage, a first display 15 is arranged on the upper stage, and a second display 16 is arranged on the middle stage. First and second indicators 15, 16
Are each composed of a 4-digit segment type display element. The operation method of each of these operation keys and the display method on the display unit will be performed at the same time as the description of the setting operation in the next embodiment.

Regarding the setting operation of the embodiment, mainly a flowchart of FIG. 3, a block diagram showing a functional configuration of FIG. 1,
It will be described in detail below with supplementary reference to the front view of the front panel of FIG. In step S1, the operation mode is switched to the setting mode of various parameters. To do so, the parameter setting mode can be entered by holding down the selection key 11 in FIG. 2 for about 3 seconds.

In step S2, a parameter is called, which is the selection key 11 or the down key 1.
3 and up key 14 to change the required parameter
This is done by displaying the symbol on the display 15. Step S3
In order to change the set value, use the shift key 12 to select the digit you want to set (change) (the selected digit flashes), then use the down key 13 and up key 14 The setting numerical value to be changed is displayed on the second display 16. Do the above for all digits.

In step S4, it is determined whether or not the changed set value displayed on the second display 16 is different from the current set value stored in the memory 2 (see FIG. 1).
Is determined by As a result of the determination, if YES, the process proceeds to step S5, and if NO, the process proceeds to step S6. In step S5, the change / registration unit 4 changes the set value
The present setting value stored in the memory 2 is replaced and stored, and is also registered (determined). That is, the change setting numerical value is changed and registered.

In step S6, the above procedure is repeated returning to the previous stage of step S2 until the change of all parameters is completed. In step S7, the operation mode is switched to, and the series of setting procedures ends. Here, in the operation mode, the actual measured value is displayed on the first indicator 15.
The set value corresponding to the second display 16 is displayed. In addition,
The steps S4 and S5 surrounded by the broken line are the comparison unit 3
It should be noted that this is automatically performed by the change / setting unit 4 and does not require any additional operator operation. This point is a feature of the embodiment, and it is possible to partially delete the operating procedure and shorten the setting required time as compared with the conventional example. That is, in the conventional example, the registration operation is required by the operator, or it is automatically regarded as the registration after waiting a fixed time after the setting is changed.
