Description

454 470 centered on the cathode ray tube screen in bar graph format, such as in a sequence instruction, and below a preferred embodiment will be form to be described in detail. The data instruction as here referred to is an instruction to process a data register (D) which is a memory containing several pieces of information.

Examples of such data instructions are the following: (1) '= nl nz The function result must be "l" if (D1) = (ÜZ). (2) <D1 D2 The function result must be "1" if (D1) <(D2). (3)> 91 Dz The function result must be "1" if (D1)> (D2). (4) MOV D1 D2 (D1) shall be transferred to (D2). (5) + nl nz (D1) + (D2) + (D2) Conditions: l. (D1) represents the contents of the data register D1. 2. (D2) represents the contents of the data register D2. The function result "1" represents a state where a contact is closed in the step diagram.

The attached figures show Fig. 1 schematically shows the essential properties of a programming device, Fig. 2 is an instruction in the form of a step diagram, Fig. 3 is a block diagram of a preferred embodiment of a device in accordance with the present invention, Fig. 4 is a view of a keyboard arrangement for use with the device according to Fig. 3, 454 470 Fig. S is a sequence diagram illustrating the keyboard the programming operations, Fig. 6 is a step diagram comprising data instructions, Fig. 7 the storage format of circuit information, Fig. 8 is a character code string, Fig. 9 shows the manner of presenting various instructions, and Fig. 10 shows an example of the program corresponding to step the diagram in Fig. 6.

The keyboard 3 in Fig. 3 consists of a plurality of keyboards. for the presentation of a step diagram of the cathode ray tube, and an embodiment of this keyboard is shown in Fig. 4. I Fig. 4 is the data instruction keys 40 and the data instruction keys. the circuit element keys 100 the new keys which are not conducted as with conventional keyboards. The other tangents keys 20, 30 and 50 are the usual number and symbol keys for control of input / output and a "drive" or process start key.

A keyboard controller 6 in Fig. 3 operates to store operation data from the keyboard 3 in a circuit information memory 8 such as circuit information. An example of key the table operation method or sequence for the presentation of the step diagnosis according to Fig. 6 including data instructions on the screen is shown in Fig. 5, and when the keyboard is operated as shown in Fig. 5, circuit information is stored in the circuit information. memory 8 in the format shown in Fig. 7 by the table controller 6. In this case, the symbols + r, X, 100, etc in the form of a circuit information code of binary digits.

Next, a circuit information + character code conversion- Fig. 3 in Fig. 3 for converting the contents (ie circuit information codes) of the circuit information memory 8 to a character code string similar to that shown in Fig. 8, and then this string is stored in a character code memory 7. Details of the character code portions 7A, 8A, _9A, 10A and 10B in Fig. 8 are shown in fig 9.

In Fig. 9, 7A denotes the method of presenting a contact, 8A a b-connector and 9A a coil, each element being expressed using 6 characters on screen 2 from the keyboard i_fig 4. 454 470 On the other hand, 10A and 10B denote methods of pre- center data instructions, both of which are expressed on the screen using 18 characters, which in length correspond to three contacts or coils.

Figures 8 and 9 thus illustrate characters such as the present on the screen. In practice, however, these signs will stored in memory 7 in the form of a binary code character code corresponding to each character.

A character generator 4 in Fig. 3 operates to generate characters presented on the screen corresponding to the character codes stored in the character code memory 7, and a conversion from character codes to characters are executed by the screen controller 5, wherein the characters are then presented on screen 2.

As described above, a step diagram similar to in Fig. 6 on the screen by the key operation sequence sen in Fig. S.

An example of the program that corresponds to the step diagram in Fig. 6 is shown in Fig. 10. In Fig. 10 the instructions correspond LD X 10 O, LDI X 150, OR T15 and OUT Y233 against the elements 6A, 6B, 6C and 6D in Fig. 6.

For the sake of clarity, Fig. 10 shows an instructional string or a program. However, it will be appreciated that codes corresponding to each instruction are stored in the software net 9. I Now the circuit information code stored in is converted the circuit information memory 8 of the above-mentioned means to an instruction code through a circuit information ++ instruction code conversion alarm controller 12 and stored in the program memory 9. The information can also be transferred and stored from element 9 to elements by conversion in the unit 12.

Finally, the instruction code stored in the software the memory 9 of the control unit 10 for data transmission, reception with the program controlx is transmitted to the program control113. Although- reverse information flow can take place via the control unit 10.

According to the method described above is presented from the keyboard entered data on the screen via the elements 3 + 4 + + 8 + ll + 7 + 5 + 2, and this data can also be transmitted to the program control as an instruction code or a 454 470 program using the elements 8 + 12 + 9 + 10 + 13. Then can the instruction code of the program control is presented on the screen as a step diagram using the elements 13 + 10 + 9 + 12 » + 8 + ll + 7 * 5 + 2.

The above examples present data instructions by enclosing in parentheses with a food symbol. Emeller- time, the symbols "<", ">", ",", etc can also be used.

Finally, the step diagram (Fig. 6) will be described below.

The circuit on the top line represents the case that a processing input No. 100 (X 100) becomes "HIGH" (logically "1") and (D 123) and (D l50) coincide, a process is activated output 123 (Y 123). The circuit on the bottom line represents in the event that a processing input No. 150 (X 150) becomes "LAG" or a timer No. 15 (T 15) becomes "HIGH". wherein (D 20) is transferred to (D 30).

As described above, in accordance with the present invention invention data instructions for processing several information at the same time presented on a step-by-step display food or cascade format as in the case of a sequence instruction for processing an information piece, which is essential improves the programming method in relation to the conventional flowchart format.
