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,
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.
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.
And then output to the output interface, control the external drive.
Output type: transistor source / drain type.
Output points: 8 points.
Load voltage: DC5/12/24/48.
Load current: 2A.
Connection mode: terminal row.
Common public end points: 1.
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 MITSUBISHI A1SJ71AS92.
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
A1SJ71AS92
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic MITSUBISHI A1SJ71AS92.
And the control principle is decentralized, centralized and hybrid control three. I/O slots: 3 slots.
Outline dimension: 255*130.
CPU basic board can be plugged into 1 power modules,
1 CPU components and a maximum of 2, 3, 5, or 8 single slot size special function components and I/O components are respectively inserted and arranged.
Expansion ports are arranged on both sides of the base plate,
For connecting the expansion board for MITSUBISHI A1SJ71AS92.
Up to 3 extension substrates. By MELSECNET/B I/O can be decentralized control.
In a main PLC station this module can control up to 512 I/O points A1SJ71AS92 MITSUBISHI.
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 A1SJ71AS92 MITSUBISHI.
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 A1SJ71AS92 MITSUBISHI.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming languagee is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-tto-one correspondence between the ladder diagram and the ladder diagram MITSUBISHI A1SJ71AS92 A1SJ71AS92. Its characteristics are basically consistent with the ladder diagram language.
