Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention operates by operating a mouse or the like on a display screen such as a CRT or a plasma display to select an input command, and corrects or changes the screen for programming. The present invention relates to a programming method for a digital controller.

[Conventional technology]

Conventionally, as a programming method for this kind of digital control device, there is one shown in FIG. In the figure, 1
And 2 are input commands, for example, 1 is addition of 5 inputs (+), 2
Indicates a 5-input multiplication (*) symbol, and IN _{11 to} IN ₁₅ ,, IN
_{22 to} IN ₂₅ are inputs to the input commands 1 and 2, and OUt ₂₁ is an output of the input command 2. Further, 5 indicates a cursor, and 6 indicates a programming area.

Next, the operation will be described. First, the display position of the logic instruction on the program screen is given in advance, select the logic instruction and connect the input and output by operating the mouse etc. to move the cursor, select the input / output symbol from the symbol menu, Set up. Also, the display format of instructions such as the number of inputs and outputs is fixed regardless of the number of inputs used.

Further, FIG. 4 shows an example of logic symbols in which the input numbers of input instructions are not necessarily the same. Even if the same addition instruction such as a 2-input instruction or a 5-input instruction is used in advance as a programming method in this case. It is treated as another instruction having a different number of inputs, and the input instruction is arranged at an arbitrary position on the screen using a pointing device such as a mouse. Then, similarly to FIG. 3, the connection of the input / output command is set while moving the cursor.

Further, as shown in FIG. 4, the input IN ₁₁ input commands 1, 2, 3
~ IN ₁₅ , IN ₂₂ ~ IN ₂₅ , IN ₃₂ or output of input command 3
The OUt ₃₁ selects a logic symbol from the instruction selection area 7 and appropriately modifies and changes it to program-form a connection diagram of logic instructions.

[Problems to be Solved by the Invention]

Since the conventional programming method of the digital controller is performed as described above, it is desirable to display the programming so that a large amount of information that can be understood at a glance can be input in the screen of the restricted size. Instead, a fixed display area for 5 inputs is actually secured even when 3 inputs or 4 inputs are added. Therefore, there is a problem that the amount of information in one screen is restricted, the utilization efficiency of the screen is reduced, and there is a problem in understanding the entire program through the display screen.

The present invention has been made to solve the above problems, and by setting the command display area so that it can be variably secured depending on the number of inputs, even if the input commands have different numbers of inputs. , The purpose of the present invention is to obtain a programming method of a digital control device which improves the utilization efficiency of the screen and helps in understanding the whole program.

[Means for Solving the Problems]

In the programming method of the digital control device according to the present invention, a command input area and a command display area are separately configured on a display screen, and the command is input according to the number of input commands set in the command input area. The display area of the instruction displayed in the display area can be variably set.

[Action]

The command input area of the display screen according to the present invention is used to determine the number of logic inputs, and the command display area displayed in the command display area is variable according to the number of logic inputs determined in the command input area. To be possible.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings. In the figure, the same parts as those in FIGS. 3 to 4 are shown by the same reference numerals in FIG.
Is an instruction input area.

Next, the operation will be described. First, the command input area 9 and the command display area 8 are separately provided in the display screen according to the present invention. When the input / output connection is completed in the command input area 9, the command display area 8 is moved to and displayed. Therefore, the display area of the instruction to be displayed can be changed according to the number of inputs set in the instruction input area 9.

That is, in the present embodiment, all of the addition instructions are five-input instructions, so when displaying the logic connection diagram using the cursor 5 in the instruction input area 9, all five inputs can be connected to the input symbol. It is in a state. In this state, the cursor 5 is moved by the mouse, and when the connection of all 5 inputs is completed, the screen is moved and displayed like the input command 1. When only the first two inputs of the five inputs are connected and used, the input command 3 is displayed. Therefore, the screen display of the command display area 8 is composed of the minimum necessary area.

In the above-mentioned embodiment, the connection order of the inputs to be used is explained as being continuous, but it may be discontinuous as shown by the cursor 5 in FIG.

〔The invention's effect〕

As described above, according to the present invention, while the number of input commands input is determined in the command input area, when the input commands are displayed in the command display area, the input command input determined in the command input area is input. Since it is configured to set the display area of the input command according to the number, it is possible to improve the utilization efficiency of the display screen, as a result, it is possible to increase the amount of information in the display screen and to understand the entire program. Has the effect of facilitating.

[Brief description of drawings]

FIG. 1 is a model diagram of a display screen of a programming method for a digital controller according to an embodiment of the present invention, FIG. 2 is a model diagram of a display screen showing another embodiment, FIGS. 3 and 4.
The figure is a model diagram of a display screen showing a programming method of a conventional digital controller. In the figure, 1, 2, and 3 are input commands, 5 is a cursor, 8 is a command display area, and 9 is a command input area. In the drawings, the same reference numerals indicate the same or corresponding parts.
