The popularization and application 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 A1SJ71PT32-S3 datasheet PDF catalog A1SJ71PT32-S3 PDF datasheet A1SJ71PT32-S3
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 A1SJ71PT32-S3 datasheet PDF catalog A1SJ71PT32-S3 PDF datasheet.
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 A1SJ71PT32-S3 datasheet PDF catalog A1SJ71PT32-S3 PDF datasheet. 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 difficult to achieve the user program.
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 CPU.
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. Output points: 16 points.
Voltage: DC24V/AC240V, 2A/1 point, 16A/ all points.
Output type: relay output.
Response time: 12ms.
All points of independence.
38 point terminal station.
The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor.
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal.
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc..
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process.
Control solenoid valve required I/O points by the action principle of the solenoid valve can be known,
A single coil solenoid valve with PLC conttrol to 2 input and 1 output,
A double coil solenoid valve requires 3 inputs and 2 outputs,
A button needs an input; a light sensitive switch needs 4 or 2 inputs,
A signal lamp needs 1 output, band switch,
Several bands are required for several inputs,
In general, a variety of position switches are required to take up 2 input points A1SJ71PT32-S3 datasheet PDF catalog A1SJ71PT32-S3 PDF datasheet A1SJ71PT32-S3 datasheet PDF catalog A1SJ71PT32-S3 PDF datasheet.
