Abstract

PURPOSE:To solve a trouble for managing a program attending on the elimination of a program step or labor and time for carrying-down the following step in the case of adding the step. CONSTITUTION:In eliminating the step, the presence of a step to be erased is judged (S1) and in the case of the presence of such a step, the step number is selected (S2). Then, in the setting order (time) input of the step, step eliminating data regardless of the time (such as numerical value 99, for example,) is inputted (S3) and matching is completed (S4). In the case of adding the step, prescribed time and control contents are inputted to the step inputting the step erase data and afterwards, the steps are rearranged in the time order as necessary to be executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program control device, and more particularly to a program control device for performing a predetermined control on an object to be controlled according to a step of a preset order (e.g., time order) input in advance. ..

[0002]

2. Description of the Related Art FIG. 4 is a basic block diagram showing the relationship between a program control device of this type and a controlled object. In the figure, 1 is a program control device, 2 is a set value input unit provided in the control device 1, and 3 is a controlled object. Here, the program control device 1 uses the preset order of input,
For example, for each program step (setting frame) in time order,
The set value input unit 2 is for performing a predetermined control on the controlled object 3, and for setting and inputting a step number of the program, its execution time, control contents, and the like.

Next, an example of control by the program control device 1 will be described below with reference to the program shown in FIG. In this figure, a predetermined number N of steps in the program are prepared in advance, and the setting value input unit 2 sets all of these steps. Each step corresponds to the contents of the control to be executed in the order of time as a setting order. In step 1, the control A starts from time 1:00.
In step 2, the control B is performed from time 5:00, in step 3, the control D is performed from time 8:00, and so on.

[0004]

The program shown in FIG. 5 will be described below. First, if it is desired to delete a step in the middle of the time sequence, for example, step 2, an easy method is to change the control content from time 5:00 in step 2 from B to A. As a result, the control A according to step 1 is substantially continued until the time 8:00 in step 3, and the control B according to step 2 until then is continued.
Has the same result as deleting. However, according to this, there is an unnecessary step 2 thereafter,
There is a problem that program management becomes difficult.

Next, consider the case where another step is inserted in the middle of the time sequence. For example, assuming a case where a step of performing control C from time 3:00 is inserted, this step is called a new step 2 from before and after the time,
It is necessary to carry out the previous steps 2 to N in order.
In this way, the work of moving down the steps must be performed by the operation of the operator, and the processing is extremely complicated.

The present invention has been made to solve the above problems, and its purpose is to eliminate the difficulty and complicated work of program management, and to make it easy to delete or add steps. To provide a program control device.

[0007]

In order to achieve the above object, the first aspect of the present invention uses a program control device for sequentially performing control for each program step according to the setting order, in which the setting order of the steps to be deleted is input. A means for inputting step deletion data unrelated to the setting order,
All steps including the step in which the step deletion data is input are automatically rearranged as necessary, and means for executing other steps except the step in which the step deletion data is input in the set order is provided. It is a thing.

A second aspect of the present invention provides means for retrieving a step in which step deletion data unrelated to the setting order is input to the setting order input, and steps for adding the step in which the step deletion data is input. It is provided with means for inputting a predetermined setting order and control contents, and means for automatically rearranging all steps as necessary and executing them according to the setting order.

[0009]

According to the first aspect of the present invention, step deletion data such as numerical values and codes which are not related to the setting order (for example, time order) is input to the setting order input of steps to be deleted. The program control device refers to the setting order of all steps, and saves the step in which the step deletion data is input, for example, after the final step,
While automatically advancing the steps other than this,
The corresponding control contents are executed according to the setting order.

According to the second aspect of the invention, first, a step in which the step deletion data is input in the setting order input is searched, and a predetermined setting order and control contents are input as a step to be newly added. .. The program control device rearranges all the steps including this step as necessary so as to be in the set order, and then executes the control content corresponding to all the steps according to the set order.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first invention will be described below with reference to the drawings. FIG. 1 is a flowchart showing the processing contents when a certain step in the program is deleted in this embodiment. First, consider a case in which the initial program steps are as shown in FIG. 5 and step 2 is deleted in the same manner as described above.

In this embodiment, first, it is determined whether or not there is a step to be deleted (S1 in FIG. 1), and if there is a step to be deleted (S1 YES), the operator selects a step number (S2). In this example, 2 is selected as the step number. If there is no step to be deleted (NO in S1), the process is ended as it is.

After selecting 2 as the step number to be deleted, as shown in FIG. 2, data not related to the time, for example, the numerical value "99" is input as the step deletion data in the setting order input, that is, the time input in step 2. (S
3). This step deletion data may be any numerical value or code as long as it has nothing to do with time. It should be noted that the "data" used herein includes numerical values and codes. The input of the step deletion data completes the settling operation (S4).

When the operator changes the previous setting sequence of step 2 to the step deletion data "99" irrelevant to the time, the program control device judges that this step should be deleted, and sets the corresponding control content. ignore. Also, this step is evacuated after the final step (previous step N), and the previous step 3
Each subsequent step is newly recognized as a step after step 2, and after step 1 in FIG. 2, step 2 (previous step 3), step 3 (step 4), and so on are automatically rearranged. Execute sequentially.

Next, FIG. 3 is a flowchart showing the processing contents when a certain step is added to the program in the embodiment of the second invention. Add steps
Executed by entering the desired time and control content to be added to the step in which the numerical value "99" that is the step deletion data is input in the setting order input, based on the program in which the step is deleted by the above processing To be done.

That is, in FIG. 3, it is judged whether or not a step is added to the program (S11), and when it is added (S11 YES), the step deletion data "9" is added.
The step in which "9" is input is selected (S12).
Then, an arbitrary time (for example, 5:00) and a control content (for example, B) to be set are input (S13). This completes the settling operation (S14).

Due to the additional processing of this step, there is a possibility that all the steps are not necessarily arranged in the order of time, and the processing for determining the order is required when each step is executed. However, when a step is added, the program control device itself sets the order of the steps of the program (time).
By automatically reading and re-arranging each step in order of time, the process of determining the order when executing each step becomes unnecessary, and program management becomes easy.

The present invention is applied to, for example, an LR control panel that digitally controls a load tap switching transformer (LRT), but is also applied to various program control devices. It is possible.

[0019]

As described above, according to the first aspect of the invention, the desired step is deleted by simply inputting step deletion data unrelated to this step to the setting order input of the step to be deleted. As described above, there is no inconvenience that program management becomes complicated due to remaining unnecessary steps. Further, according to the second invention, it is possible to add a step only by inputting a predetermined setting order and control content to the step having the step deletion data,
After that, the steps can be automatically rearranged according to the set order to eliminate the trouble of the operator. Furthermore, since steps can be deleted and added without being restricted by the setting order, operability is improved and processing speed is improved.
