Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a step-by-step stored program type sequence programmer.

It is desired that so-called general-purpose sequence programmers, which set an appropriate program corresponding to any controlled device and manage its sequence control, be enriched with functions so that they can meet various control requests. On the other hand, even if the functions are enriched, it is important to simplify the operation as much as possible so that even a person without specialized knowledge can easily set and change the program.

The present invention provides a step-by-step stored program type sequence programmer that sets an arbitrary control program by operating keys on a program console, writes it into a program storage section, and performs sequence control of a device to be controlled based on the program. This was designed to make the program settings easier to understand and at the same time improve its operability. Among the operation keys on the program console, the first key group, which is unified in the first color, allows each A second key group is used to input an operation mode that defines the mode in which the process is to proceed, and operation data that specifically defines the contents of that mode, and is unified in a second color different from the first color. This provides a sequence programmer configured to input output data that defines the output content to be executed in each step.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 shows the appearance of a sequence programmer according to the present invention, and FIG. 2 is a block diagram showing the outline of its configuration.

In the figure, 1 is the main body of the device, and 2 is the main body 1 of this device.
A program console is detachably connected to the computer via a cord 3. The main body 1 of the apparatus has built-in an arithmetic control section 4 such as a microcomputer, a storage section 5 for storing programs set as described below, an input unit 6 as an input interface, and an output unit 7 as an output interface. The input unit 6 is connected to a plurality of input devices 6' such as limit switches and photoelectric switches related to the equipment to be controlled (in the embodiment, there are 16 systems, and the addresses are set from 1 to 16).
The output unit 7 is connected to a plurality of output devices 7' such as relays related to devices to be controlled (16 systems, numbered from 1 to 16).
In addition, the front panel section 8 of the device main body 1 includes a power switch,
An operation section 9 is provided, which includes a main changeover switch for switching between automatic operation, manual operation, program writing, and program monitor operation modes, as well as various operation switches for manual operation, as well as program setting operations and program monitor operations. A program display 10 for displaying the contents of a program for one step (stroke) at a time.
and an output display 11 are provided, and a program comparison table 12 is also provided in correspondence with the program display 10. The program console 2 is used when writing and monitoring programs, and as shown in detail in FIG.
14 keys with symbols "A" to "D" and "ON"
” and “OFF” are arranged in 4 rows and 4 columns, with 4 keys on the left and 2 keys on the right.
Keys with predetermined symbols on them are provided, and a changeover switch SW is also provided. A total of 22 operation keys mentioned above are unified into the first color, which is represented by a dotted pattern in the figure, according to their purpose corresponding to the content of the program, which is roughly divided into two types as described later. a first key group;
In the figure, the second key group (specifically, "
They are classified into two groups according to the color of the keys: ``OUT'' key, ``ON'' key and ``OFF'' key.
Further, a program comparison table 13 is provided at the upper part of the panel surface of the program console 2. Now, the contents of the program set in this sequence programmer are the output data for each step to be executed at each step (in other words, the logical value of whether to turn the output of each address of the 16 systems ON or OPN) It is broadly divided into operation mode, which defines the mode in which each step is to proceed, and operation data, which specifically defines the contents of the mode.

The above program display 10 includes a display "STEP" that displays the number of steps, and a display "SYM" that displays symbols corresponding to each operation mode (symbols of the data key DK of the program console 2).
It consists of two displays, ``DATA, 1'' and ``DAT'', on which the operation data is displayed. The output display 11 is constructed by sequentially arranging one light emitting element corresponding to each output from address 1 to address 16. The program comparison tables 12 and 13 show the contents of each operation mode, the key symbol of the program console 2 corresponding to each operation mode, and the contents of operation data necessary for each operation mode. This is shown in a form that corresponds to the display on the display 101.

Each operation mode will be explained based on the program comparison table 13 shown in FIG. “TIMER” corresponding to symbol “0” is “DATA, 1” and “DA
This is a timer step mode that advances to the next step when the time set in "T" is counted.

“COUNTER” corresponding to symbol “1” is “D
This is a counter step mode that advances to the next step when the input signal at the address set in "ATA2" has been counted by the number set in "DATA, 1". "INP." corresponding to the symbol "2" is This is an input condition step mode that advances to the next step when there is an input signal at the address set to "DATA, 1." Corresponding to the symbol "3J"
INP・AND” is “DATA, one” and “DATA
Input condition A that advances to the next step when the AND condition of the two input signals at the addresses set in "2" is satisfied.
This is ND step mode. “I” corresponding to symbol “4”
NP/OR" is "DATA, 1 and "DATA2"
This is an input condition OR step mode in which the step advances to the next step when the logical sum condition of two input signals at addresses respectively set in is satisfied. "JMP" corresponding to symbol "5"
is a jump command that unconditionally jumps to the step set to "DATA, 1". "COND JMP" corresponding to symbol "6" is a jump command when there is an input signal at the address set to "DATA2". This is an input condition jump command that jumps to a step set to DATA, 1, and advances to the next step if there is no input signal.
"REPEAT-JMP" corresponding to the symbol "7J"
is a repeat jump command that repeats the jump to the step set to "DATA, 1" the number of times set to "DATA2", and then advances to the next step when the repetition is completed that number of times. Similarly, operation modes are set corresponding to the "A" to "C" keys, and "END" corresponding to the last symbol "D" is a stop command that jumps the program step to step 0 and stops the operation. It is. In this way, among the keys in the center of the program console 2, the operation mode is set corresponding to each of the 14 keys included in the first key group unified in the first color. Furthermore, "DATA, 1" and "DATA2", that is, operation data can be input using ten numeric keys. Next, the operating procedure for setting and writing an arbitrary program will be explained.

First, when the changeover switch on the operating section 9 of the apparatus main body 1 is set to "program writing", "1" is displayed on the "STEP" indicator in the program display 10, and the apparatus enters a first step program writing standby state. Therefore, for example, if you want to set the timer increment mode for 34 seconds in this first step, first
If you press the "P" key and the "0" key corresponding to the timer increment mode, the operation mode will be set to "0".
" is set, and "0" is displayed on the display "SYM old OL". Next, the "3" key on program console 2,
When you press the "4" key in sequence, the display "DATA" and "3"
4" is displayed, and then "0" on the program console 2 is displayed.
” key is pressed, “0” is displayed on the display “DATA2J”, thereby setting the set time of 34 seconds. In this way, the operation mode that defines the mode in which each process proceeds and the operation data that specifically defines the contents of that mode are set by operating the first group of keys on the program console 2. This is not limited to the timer increment mode described above, but is the same for each operation mode described above. After the operation mode and operation data setting operations described above, output data to be executed in this first step is set.

This output data setting operation is performed using the program console 2.
This is done using the second group of keys in the second color mentioned above, first press the "OUT" key, then operate the "ON" key and "OFF" key to turn on the output of each address. Starting from address 1, key in whether to set it to OFF or to OFF. At this time, in the output display 11 consisting of light emitting elements corresponding to the output of each address, first
When the "OUT" key is pressed, the light emitting element at address 1 flashes,
The display indicates that the output data at address 1 is ready to be set.If the output of address 1 is set to OFF, this light emitting element will remain off, and if set to ON, it will remain lit. The set contents are displayed.

When the data set for the output at address 1 is completed, the light emitting element at address 2 blinks to indicate that the data set at address 2 is in standby mode, and the output contents for each address are set in sequence in the same manner as above. It is. After setting the output data up to one captured area, the program display 10
Then, check the output display 11 to see if there are any errors in the program set, and if there are no errors, press the "W" key on the program console 2.

Then, the first step program set as described above is introduced and written into the storage section 5. At the same time, the displays on the program display 10 and output display 11 are reset, "2" is displayed on the display "STEP", and a second step program writing standby state is entered.
Thereafter, the program for each step is sequentially stored in the storage unit 5 in the same manner.
This is written in . Furthermore, when the main selector switch of the operation section 9 is set to "program monitor", the program written in the storage section 5 is read out in step order, and the contents of the program are displayed on the program display 10 and the output display 11 one step at a time. Is displayed. Furthermore, program console 2
By switching the changeover switch to the "SET-STEP" side and operating it according to a predetermined procedure, the program of any step can be monitored, and the program of any step can also be written. In addition, as a means of distinguishing the operation keys of the program console 2 by color, if the keys are molded with synthetic resin, the resin itself may be colored, or the surface of the keys may be colored with paint, or the key A colored plate may be attached to the surface of the key, and furthermore, the hue can be made different by forming unevenness in a fine pattern on the surface of the key.

As explained in detail above, the sequence programmer according to the present invention sets the above-mentioned operation mode and operation data using the first key group unified in the first color among the many keys of the program console, Since the above-mentioned output data is set by a second key group unified to a second color different from these,
It has become extremely easy to understand the program contents and program setting procedures, and it has become easy to operate without errors, making it easy for ordinary people without specialized knowledge to use this type of sequence programmer. The effect of increasing its versatility and practicality is extremely large.
