AnS, QnAS bus connection, the reader to write program 1 channel connection.
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 AJ71AR21 PDF.
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 AJ71AR21
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 AJ71AR21 PDF.
This phenomenon is called the I/O delay time effect AJ71AR21 PDF. A6WU-A6PHP/A6HGP connection cable.

Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF MITSUBISHI User's Manual.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Switch volume control is designed to,
According to the current input combination of the 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 MITSUBISHI User's Manual AJ71AR21 Manual .
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three. 2 slots.
Installation of the power unit can not be used for AnS QnAS/ series units installed MITSUBISHI User's Manual.
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.
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.
PLC user program is designed acccording to the control system of the process control requirements,
PLC programming language through the preparation of specifications, in accordance with the actual needs of the use of the function to design AJ71AR21 User's Manual.
As long as the user caan master some kind of standard programming language,
To be able to use PLC in the control system,
To achieve a variety of automatic control functions AJ71AR21 Manual .
