Description

DETAILED DESCRIPTION OF THE INVENTION A. Industrial Field of Application The present invention is directed to visual visualization of equipment that inputs a sequence control circuit to a programmable controller (hereinafter referred to as a sequencer) that performs sequence control using a microcomputer. In particular, regarding the loader circuit input method,
This article relates to a manual circuit system for a standard circuit system loader.

B9 Summary of the Invention The present invention, in the circuit input method of a loader that inputs a sequence control circuit to a sequencer, manually inputs a standard circuit in an alternate number format as a pattern, converts the pattern into a hierarchical level using a Boolean algebraic expression, The standard circuit registration process involves creating input tables corresponding to the above and registering them, and the application involves reading out the input table, applying element numbers and contact types to the substitution numbers, and then calculating Boolean algebraic expressions to develop a sequence control circuit. This technology provides a technology that reduces the number of manual keystrokes and significantly shortens the input time by including a circuit creation process.

C9 Prior Art A visual loader is often used to manually control a sequence control circuit in a sequencer, and input is performed using symbol keys provided on the front of the loader.

FIG. 8 is a partial circuit diagram showing an example of a sequence control circuit. In the figure, symbols 1, 2, 4, and 6 indicate A contacts, and 3
．． The symbol 5 indicates a B contact, and the symbol 7 indicates an output command, a numerical part, or a relay number. To manually construct such a circuit, normally 22 key operations as shown in FIG. 8(b) are performed.

However, in the figure, m, IC, IB, and Q are branch symbols.

D1 Problems to be Solved by the Invention If the key operations as described above were repeated each time the circuit was operated manually, it would take too much effort and time. Therefore, in order to simplify input, a loader with standard circuit functions was devised. This is a method in which, when a similar circuit pattern is used repeatedly, the circuit is registered in advance as a standard circuit, and this is called every time necessary to change the relay number. For example, if the circuit shown in Figure 8(a) is registered as a standard circuit, then for a circuit pattern like the one shown in Figure 9, it is only necessary to change the relay number, which is extremely convenient. .

However, such a standard circuit system has the disadvantage that it cannot cope with even the slightest change in the circuit pattern.For example, for the circuits shown in Figures 10 and 11, input is made one circuit at a time using conventional key operations. Otherwise, the only option was to develop a standard circuit and then make changes, which required a great deal of effort and time.

The present invention was created in view of these problems, and
The purpose of this invention is to provide a circuit input method for a sequencer/loader that reduces the number of key input circuits and significantly shortens the input time for most sequence control circuits.

98 Means for Solving the Problems The means for solving the above problems in the present invention is a sequencer? In the circuit manual method of the visual loader that inputs each sequence control circuit, a standard circuit in alternate number format is input as a pattern, the pattern is converted to a hierarchical level using a Boolean algebraic expression, and an input table corresponding to the alternate number format is created. It has a standard circuit registration process that creates and registers them, and an applied circuit creation process that reads an input table, applies the element number and contact type to the alternate number, and then calculates a Boolean algebraic expression to develop a sequence control circuit. This shall be based on the circuit input method of the sequencer/loader.

10 Effects The present invention addresses the problems through two major technical improvements.

One method is to input the standard circuit in alternate number format and set an input table corresponding to the alternate numbers, thereby making it possible to deal with cases where the relay or element numbers are different.

The other method is to input the standard circuit pattern by converting it into hierarchical levels using Boolean algebraic expressions, which makes it possible to deal with cases where the patterns are different.

Figures 1 and 2 are process diagrams showing the basic principles of the present invention, with Figure 1 showing the process of registering a standard circuit, and Figure 2 showing the process of registering a standard circuit based on the registered standard circuit. It shows the process of creating an application circuit.

In FIG. 1, the standard circuit registration process includes a step of inputting a standard circuit in an alternate number format as a pattern, a step of converting the pattern into a hierarchical level using a Boolean algebraic expression, and creating an input table corresponding to the alternate number format. In FIG. 2, the applied circuit creation process consists of a process of reading an input table, a process of applying an element number to a substitute number in the input table, and a process of calculating a Boolean algebraic expression. The process consists of a step and a step of developing a sequence control circuit by calculation.

That is, by using the standard circuit registered in the process shown in FIG. 1, it becomes possible to develop a desired applied sequence control circuit in the process shown in FIG.

G. Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIGS. 1 and 2 are process diagrams showing one embodiment, which also serve as illustrations of the basic principle of the present invention. FIG. 1 is a process diagram of standard circuit registration, and FIG. 2 is a process diagram of application circuit creation in which an application circuit is created based on the registered standard circuit.

The process of standard circuit registration is, for example, 1 as shown in Figure 8.
When a circuit is received, first, as shown in FIG. 3, the numbers of elements and relays are replaced with alternate numbers Y1 to Y7, and then input as a pattern. Next, the input standard circuit is expressed using Boolean algebra. The circuit shown in FIG. 3 is expressed by the following algebraic expression.

(Y1+y2)* (Y3+Y4*Y5+Y6)* Y
7 This algebraic expression is shown in the hierarchical level as shown in FIG. Since this hierarchical level is expressed in the form of a substitute number, an input table corresponding to the substitute number is created as shown in FIG. 5 and registered (stored) together with the hierarchical level. At this point, the input table only contains the alternate numbers in the first row, and the lower row is blank.

In the process of creating an applied circuit, one circuit is received, and if there is one similar to a registered circuit pattern, the input table is read out and the element number is applied to the alternate number in the input table. At this time, parts that are not used are left blank without input, and B is added to the number for the B contact part. The circuit shown in Figure 9 will look like column (A) of the input table shown in Figure 5, and the circuit shown in Figure 10 will look like column (B) of the input table, and the circuit shown in Figure 11 will look like column (B) of the input table. The circuit shown in column (c) of the input table looks like this. Next, the Boolean algebraic expression is computed to recreate the stacking levels. At this time, if there is one or less layers hanging below the operator, the operator is also omitted. As a result, for example, in the case of column (b) of the input table, 100 * (300 +
400B* 500 + 600)* 700,
The hierarchical level is as shown in FIG.

When this is developed into an applied circuit, the circuit shown in FIG. 10 is obtained, and it can be seen that the sequence control circuit is correctly input. In the case of column (c) of the input table, (300+400
*600)* 700, resulting in a hierarchical level as shown in FIG. Developing this into an applied circuit, the 11th
The circuit shown in the figure shows that the sequence control circuit is correctly input.

In this way, in this embodiment, it is possible to make the standard circuit compatible with most sequence control circuits by simple key operations.

H0 Effects of the Invention As described above, according to the present invention, it is possible to provide a circuit input method for a sequencer/loader that reduces the number of key input circuits and significantly shortens the input time.
