Abstract

PURPOSE:To shorten the time required for writing the same program data into plural sequencer main bodies by adding a nonvolatile key input memory part capable of writing/reading the key input data into a program console connected with those sequencer main bodies. CONSTITUTION:The data are written from a key input part 14 of a program console 11. Then these data are written into a memory part 13 via a signal line 17 and a CPU part 12 and at the same time into a key input memory part 16 of the console 11. When said data are written into another sequencer main body 10, the corresponding data written into the part 16 are transmitted to the part 13 of the main body 10 via the signal lines 15 and 17 as well as the part 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sequence controller device, and particularly to a data writing device.

[Conventional technology]

Conventionally, this type of sequence controller device (hereinafter referred to as a sequencer) will be explained based on the configuration diagram shown in FIG.

In other words, 1 is the sequencer main body (sequence controller main body), in which the control circuit section composed of contact relays etc. has been replaced with a semiconductor element, and the arithmetic control section (CPU) that performs logic processing and controls the entire sequencer. Part) 2
, a memory section 3 that is connected to the calculation control section 2 and stores programs, an input section that receives external signals such as switches (not shown), and an output section that drives switches, solenoids, etc. The arithmetic control section 2, which is the central part of the sequencer, sequentially reads out the contents stored in the memory section 3 from the beginning of the program address, decodes the contents, and issues instructions to the input section and the output section.

The memory unit 3 includes a read-only memory (ROM) and a readable and writable memory (RAM).When writing to ROM, it is a time-consuming task to write data using a dedicated writing device. It is unsuitable for use when data is frequently changed, such as when adjusting a sequencer, and while RAM allows data to be easily changed as needed, data may change or disappear due to power outages, external noise, etc. Therefore, it is desirable to keep the use of RAM to the minimum necessary.Furthermore, a program console 5 is connected to the arithmetic and control unit 2 via a signal line 4 for key inputting the operation sequence. At the same time, a cassette tape 6 and a floppy disk 7 are connected, respectively.

Next, a data writing method for such a sequencer will be described.

First, a key is input to pass the sequence through the program console 5, and the key-input data passes through the signal line 4.
It is written into the memory section 3 via the arithmetic control section 2 of the sequencer main body 1. The data written in the memory section 3 is read into the cassette tape 6 and floppy disk 7 as necessary, and when copying this data to another sequencer of the same type, the data is transferred from the cassette tape 6 or floppy disk 7 to the memory section 3 of the sequencer. The data was sent to.

[Problems that the invention seeks to solve]

However, in the above-mentioned conventional sequencer, when data is written to multiple sequencers of the same type by key input from the program console 5, the data is sequentially and individually key input to the program console 5.
In addition to the problem that the work is time-consuming, when using the cassette tape 6 or the floppy disk 7, although the work time is shortened, a dedicated device is required, which increases the cost.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a sequence controller device that can speed up writing time at low cost.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a sequence controller main body having a CPU section that performs logical processing and sequence control, a memory section that is connected to the CPU section and stores program data, and a key input unit that inputs data using keys. and a program console having a non-volatile key input memory section connected to the key input section and for writing and reading out the key input data, and connecting the CPU section of the sequence controller main body and the key input section of the program console. It is equipped with a signal line for

[For production]

In the present invention, a non-volatile key input memory section in which key input data can be written and read is provided in the program console connected to the sequencer main body, so the key input data is stored in the key input memory section. The stored data is written to the memory section of the sequencer main body. Therefore, no external storage unit is required.

〔Example〕

Hereinafter, one embodiment of the sequencer of the present invention will be described with reference to its configuration diagram shown in FIG.

That is, this sequencer includes a sequencer main body 10 and a program console 1 for key inputting the operation sequence.
1, and this sequencer main body 10 is composed of:
CPU unit 1 that performs logical processing and controls the entire sequencer
2 and a memory section 13 connected to the CPU section 12 and storing program data, the program console 11 is connected to a key input section 14 for inputting data and to the key input section 14 via a signal line 15. It has a key input memory section 16 that is nonvolatile and capable of writing and reading. And, the CP of these sequencer main body lO
U section 12 and key input section 14 of program console 11
is connected to the program console 11 via a signal line 17 for transmitting signals, and power is also supplied to the program console 11 via the signal line 17.

Next, a data writing method in such a sequencer will be described.

First, data is entered using the key input section 14 in the program console 11. Then, transfer this data to signal line 1
7 and the CPU section 12 sequentially to the memory section 13, and at the same time, it is also written to the key input memory section 16 in the program console 11 via the signal line 15, and the above data is also written to another sequencer main body 10. In case,
The data written in the key input memory section 16 is transmitted to the memory section 13 of the sequencer main body 10 via the signal line 15 17 and the CPU section 12 in order with a write command from the key input section 14. '111, by providing an external power supply means to the program console 11, the program data can be entered by key input in advance without relying on the sequencer main body 10, and this data can be written into the key input memory section 16 of the program console 11. It's okay to stay.

〔Effect of the invention〕

As explained above, according to the present invention, a non-volatile key input memory section capable of writing and reading key input data is provided in the program console to which a sequencer main body having a memory section is connected, so that it can be used for multiple sequencer main bodies. When writing the same program data, the data written to the first sequencer body and the key input memory section of the program console can be written to the memory section of the second and subsequent sequencer bodies, so the conventional In this manner, the time required to write data to the program console through individual key inputs can be eliminated, and since the program console itself has a key input memory section, an external storage unit is not required. Therefore, data writing time can be fast at low cost,
The above-mentioned problems can be solved by the unique effects such as being able to save time.
