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 A1SJ71QE71N-B5 PDF catalog A1SJ71QE71N-B5
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 A1SJ71QE71N-B5 PDF catalog.
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 A1SJ71QE71N-B5 PDF catalog.
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 difficult to achieve the user program MITSUBISHI Ethernet module PDF catalog.
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 MITSUBISHI Ethernet module PDF catalog.
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. 3C-2V/5C-2V coaxial cable between the single bus PC network (control station / common station) / remote I/O network (remote master) MITSUBISHI Ethernet module PDF catalog.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on.
This phenomenon is called the I/O delay time effect.
Switch volume control is designed to,
According to the current input combination of thee switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A1SJ71QE71N-B5 PDF datasheet.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A1SJ71QE71N-B5 PDF catalog.
And the control principle is decentralized, centralized and hybrid control three.
