SUMINET-3200 network.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add A2ACPUR21 PDF.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations A2ACPUR21 Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line A2ACPUR21 PDF.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words A2ACPUR21 PDF. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure MITSUBISHI Programming Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 8k MITSUBISHI Programming Manual.
Basic command processing speed (LD command) S:1.25.
RAM memory capacity: 32K,
Computer connection with printer.
The popularization and appllication of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment MITSUBISHI Programming Manual A2ACPUR21 Manual .
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium-sized PLC systems, structured text is often used to describe the relationship between the variables in the control system.
Mainly used for other programming languages more diifficult to achieve the user program A2ACPUR21 Programming Manual.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CCPU A2ACPUR21 Manual .
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
