Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows the control sequence program stored in the memory circuit of a sequence control device to be stored not in fragments such as in instruction-word units, but in units of 7'-1 negative units. Each seek/2 points in a plane is v′S! The present invention relates to a display device that can display images at four o'clock on the same screen.

As a conventional Ji-tance control device, there is a display device using a relay symbol. CR7 indication 11 by this relay symbol, if the sequence is relatively simple, C1 passes. Recently, 7-sequence control devices have become increasingly complex as control becomes highly automated, and it has become difficult to express sequences using conventional relay symbols. Therefore, AND.

This is the sequence output to OOI.

FIG. 2 shows the configuration of a sequence control device that executes the above-described sequence and a sequence display device that displays the diatance shown in FIG. 1 using logic symbols.

First, how the sequence control device 3 performs the sequence shown in FIG. 1 will be explained with reference to FIGS. 3(A) and 3(B).

Inputs X0OI to X006 to the jitance control device 3 are taken into the input circuit 31. A control circuit 34 performs an operation on this input signal according to a sequence program stored in a main memory 33, and the result is temporarily stored in an accumulator (ACC) 35, which is a refresh memory. The contents of this ACC 35 can be output to the internal temporary storage memory 36 and stored, or can be output to the output relay yo via the output port w132.

In the same manner, sequence control a is performed according to the program shown in Section 3 (A), but this program is shown in hardware as a normal sequence control device as shown in FIG. 3 (B).
become that way. Sequence control is performed by cyclically processing these programs in the Geitance control device which is the object of the present invention.

Here, the raw 6th order code of the example program explained in FIG. 3 is shown in a table as follows.

The sequence shown in FIG. 1, which is subjected to the sequence calculation process as described above, can be displayed as a logic symbol on the CRTI shown in FIG. 2 as follows.

The sequence display device according to the present invention is composed of a sequence display device ft2 and a CRTI.

A buffer memory 24 for temporarily storing a program as shown in FIG. 3(A) stored in the main memory 33 of the sequence control device 3 in the sequence display device ff12;
A control circuit 25, a keyboard 27 for operating the sequence surface water device, and a CRTI' for displaying on a CRT.
1llJ (5! 1st inscription 21. Logic'/ :/ A program stored in the buffer memory 24 for displaying on a CRT in a hole (R, 0M26, logic symbol display containing a program to convert to a program compatible with ro logic symbols) It is comprised of a refresh memory 22 that stores programs converted for use in the computer, and a symbol generator 23 that displays logic symbols on a CRT.

Next, the procedure for displaying the program shown in FIG. 3(A) stored in the main memory 33 on the CRT will be explained using FIG. 4. When the "read circuit" key provided on the keyboard 27 of the sequence display device 2 shown in FIG. 2 is pressed, the program stored in the main memory 33 is loaded into the panzer memory 24 of the sequence display device ff1E2. The program loaded here first decodes the instruction code of the program according to the conversion program stored in the ROM 26, and extracts the '=1 instruction code.

Next, the 'S' instructions before the 0=1 instruction are extracted.

Next, “S″'' instruction 1 = the number of steps up to 1 instruction and the solution of the instruction code! ! and determine the number of input points, symbols, and addresses. This situation will be explained using FIGS. 3(A) and 3(E). First, the 1-'' instruction of (2) is extracted.

Next, the number of steps from "S" to "1=" command is 3, so the number of input points is tr!
You can see that it was a three-person effort. Next, the instruction code is the AND of ■/”IIAcc and the negation of the input, and the 1* of ■
” is the AND of ACC and the input, so the symbol is AN
It turns out that it is D. For each address, input is X0O1,
It can be seen that Mool is in the AND output of X0O2, X0O3. With the above steps, one logical 7-child symbol has been determined.

Next, when we decode the command again using the above and Oka procedure, we get 1 in ■.
=1 instruction is extracted and "S" instruction is extracted in ■. 'S
# and 6 = “It is 2 manual operation with 2 steps between minutes, the instruction code is 1+1, and it is an OR of ACC and input, so it is a 2 manual OR symbol, and the input address is MO01, XOO
4. It turns out that the output address is X002. next,
Similarly, each input UMO0 is
2.

X005. It turns out that X0O6, the output address is Yool.

Once the conversion program is determined as described above, it will be displayed on these logic symbols 'kcRT.

As shown in FIG. 5(A), this logic symbol is
It consists of three basic pixel areas.

First, AND-MODI is a block (X=3.Y=1.2
．． Automatically placed in the 3rd section, each person's power X0O1゜X0O2,X
Automatically connected to 0O3. Next, OR-MOO2 is automatically placed in the block (5-2, 3°4) so that the first input of this OR is in a straight line with the output of Mool, and each input M
Automatically tied to OOL and X0O4. Then AND-YO
OI tries to automatically arrange so that the J input MOO2 is in a straight line with the output of MOO2, but if that is done, the second manual input X0O5 and X0O6 will not be able to be connected, so
It is automatically placed in the block (7-4, 5, 6) and automatically connected to each input.

The details will be specifically explained using FIG. 7, FIG. 8, and FIG. 9. The basic idea is shown in Fig. 7, and Fig. 8 (A) shows steps 52, 53, and 54 in Fig. 7 in detail.

(B, (C)) Steps 56 and 57 in Figure M7 are shown in detail in Figure 9 (A).

(B). Logic symbols such as AND and OR are the second input signals when three people are standard, as shown in 61, 63, and 65 in Figure 8! The placement position is determined using 81 as a reference point. The logic symbol base points 62, 64, and 66 in FIG. 8 are determined by this reference point. This will be explained in II-FIG. 5(A).

Taking the OR symbol of X002 as an example, this MO020R
is the result of OR of Mool and XO04 (7) by two people'fr
This is the sequence output to OYOOI. Mo0zOR

MOO2's first human power MOOII-! The block in Figure 5 (
4, 2), and the second human power XO04f'
Since this is the signal that appears for the first time on the screen of the CRT 1, it is assigned to the input signal area of blocks (1, 4) in FIG.

Since the position of the input signal has been determined, the base point of the Mo 020R symbol is determined to be block (5, 2>) according to the principle of Figure 8 (B). Next, the OCR in Figure 1 centered on this logic symbol base point is , AND in a certain space on the TIO surface,
Check whether Q logic symbols such as OR can be placed. Here, the placeable state and (1, C to be placed
A certain space on the RTI is already occupied by another logic symbol or one
This refers to a state where it is not used due to wiring between 10 and 7 boards. If the logic symbol can be placed, the automatic position determination of the logic symbol is completed, but if the logic symbol cannot be placed, it is necessary to correct the logic symbol position in the order shown in FIG. As shown in Figure 9, the correction method is based on the logic symbol base point SP in Figure 9.
? Based on Il-, an unused area on the screen of the CRTI is extracted in the shape of a wave in the lower right direction (X-ray (+) direction, Y-axis (-) direction) with respect to the base point SK. In order to make it easier to input knock symbols such as AND and OR, the number of inputs is limited to 1 (maximum of 3 manual efforts). fd
After MOO20R symbol placement, (B) is 0CRT before placement
This is the state of the screen of I. ) Since the area (5-2, 3°4) where the M o O2OR symbol is to be placed is unused, it can be placed, and the block (5-2, 3, 4) is placed as shown in Figure 5(C). Placed. Next, a case will be described in which a timer symbol TOOL is arranged in FIG. 5(C) to create a CRTI state as shown in FIG. 5(D). MOO
Since the area (5-2, 3, and 4) in which the Tool timer symbol with input I is to be placed is already occupied by the M0020R symbol, it is necessary to correct the placement position of the tool timer symbol (5-2, 3, and 4). If 2) is set as the logic symbol base point SP and the CRTIO unused area is searched at the priority J@ position in Figure 9, the area of (5-5°6.7) is selected.Once the logic non-pole placement is determined, Next, perform the tying between the signals. In the example of Fig. 5 < D), Fig. 5 (C) and (
During the period D), a state as shown in FIG. 5(E) exists. Fifth

The connection between the signals (the fourth priority is given to a straight line)
A display like the one shown in figure (D) can be made.

Next, let's consider this arrangement priority and connection concept,
Considering the idea that the input wiring is all straight, the input is X0O5.

In this case, it is not possible to manually connect the wires 1002 and automatically connect the wires instead of using ANp-YOOI○ connection ZUBA L connection.

However, as in (4), if there is an obstacle or υ at the diagonally lined position, and there are more than 3 bends υ (in this case, it is impossible to connect without making 4 turns), the characters indicating the connection between the two points, e.g. A only indicates that the two points are connected, and the connection σ is not made.

This is effective in limiting the amount of processing time required to perform i-1, 100% connection.

The details will be specifically explained with reference to FIGS. 10 and 11. Figure 1O shows the idea of wiring with as few bends as possible, and Figures 11 (A) and (B).

It is possible to arbitrarily decide which of (B) to give priority to, the direction of the movement axis i''!, and the characteristics of the CRTI screen. This is a specific example of the speedog 74 shown in Fig. 10. Fig. 11 (C), (D

Based on the movement axes ■, ■, ■ of CB), create a branch route v and search for a route that can be routed. ■, ■ in Figure 11 (C),
This route is derived from the two-song route shown in ■ in Figure 11 (A). Furthermore, in order to reduce the number of trials of routes that can be routed, we focused on the fact that there are routes that are used overlappingly in multiple trial routes, as shown in FIG.
(B)-3, routes in 4.5.6 of Figures 11 (C) and (D)), if the route that is used overlappingly has already been used, try a route Q that includes that route. Don't do it.

The present invention (1. In this more sequence display device,
7- When making or modifying a new can,
A set of sequences is represented by i (handwritten sequence drawing 1)
By dividing the sequence into units called "sheets" (a set of tances corresponding to a sheet is called a sheet), it is possible to easily search for a sequence, and also to make it easier to rearrange the sequence program stored in the main memory 33 when modifying the notance. The aim is to significantly reduce the number of times.

As a conventional sequence search method (1, main memory 33
There are two methods: specifying an address, and specifying a code indicating the output. However, the former method has the disadvantage that it is complicated and easy to make mistakes because it is necessary to be aware of the address in the main memory where the sequence to be modified is located, and the latter method has the disadvantage that the sequence is stored in the main memory 33 at the time of modifying the sequence. The disadvantage is that the sequence program must be rearranged many times. In the present invention, the -f? As shown in FIG. 12, IJ is divided into main memory 33 (-sort units).

Next, a method of dividing the main memory 33 into sort units by operating the keyboard 27 in FIG. 2 will be described. Keyboard in Figure 2 - Example details lvi! : is shown in FIG. 13 1.

A method of dividing the main memory 33 of FIG. 2 into note units using these keys will be explained using FIG. 14. Press μzu■ to press all sheet size change keys 116. Next, the main memory 33'i'' is divided into 5 units.

After this step 11, all sequence creation and modification is performed on a sheet-by-sheet basis. The initial value for the number of words on one sheet is 32 edicts, and from then on, the number of words per sheet is O size i416.
Candy f is the unit of minimum increase or decrease, and is automatically increased or decreased when creating or modifying Nokens.

Next, the relocation of the O sequence program in the main memory 33 when the /- sequence is modified will be explained using FIGS. 15 and 16. Fig. 15 shows the case where the sheet size does not exceed the sheet size before the correction in the 7-can correction, 202, sequence controller main memo 1c (A, ) is before correction, (B) 1g after correction, 211 is 07-) 10 used sequence program before modification, 21 = II unused memory of 0 sheet 10 before modification, 221 if used sequence program of sheet 10 after modification, 7-) 10 unused memory after modification to 222 (:') indicates.

2.- The number of words became 28 candy. Since the number of songs in the sequence program used due to the sequence modification is 6 pieces, and the number of unused words in the sheet is 10 pieces, the rearrangement of the sequence program on the main memory 33 is only 32 words on sheet 10. Figure 16 shows the case where the sheet size exceeds the size before correction due to sequence correction, (A) shows the case before correction, (
B) is after modification, 203 is the sequence controller main memory,
231 is the usage sequence program of sheet 11 before correction, 232 is the unused memory of sheet 11 before correction, 2
41F! 242 indicates the unused memo Vt of sheet 11 after modification. In this specific example, the sheet size of C) 11 is 32 words, and the used sequence program 231 is 30 @ before modification.
, the unused memory 232 is two words. After performing sequence correction on sheet 11, the number of words in the used sequence program 2410 was reduced to 40 words. Due to the sequence correction, the number of used sequence program words is 10 words, which is larger than the number of unused candy words in the sheet, which was 2 words, so the sheet size is automatically increased in units of 16 fi to 48 words. Therefore, all sheets after sheet 11 have 16 words and 77 words.
will be downgraded and will be subject to relocation. However, the sheets to be rearranged are only the sheets in block l in FIG. 12.

According to the present invention, the unit of search at the time of creating and modifying a sequence is configured to be performed in units of 7 pieces.
This has the advantage that the number of rearrangements of the sequence program in the main memory when modifying the storage can be reduced, and retrieval can be performed easily and reliably.
