Common common point: 32.
Sequential function flow chart language is designed to satisfy the sequential logic control.
The process of sequential process action is divided into steps and transformation conditions,
Accoording to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions A1SJ71BR11 A1SJ71BR11.
Each step represents a control function, represented by the box.
In the box, the ladder logic is used to complete the task of the corresponding control function.
This programming language makes the program structure clear and easy to read and maintain,
Greatly reduce the programming workload, shorten the programming and debugging time A1SJ71BR11.
Used in the system of the size of the school, procedures for more complex occasions.
Sequence function flow chart programming language features: to function as the main line, in accordance with the functional flow of the order of distribution, clear, easy to understand the user program,
Avoid the defect of ladder diagram or other languages,
At the same time, the use of ladder language to avoid the use of ladder programming,
Due to the complicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced MITSUBISHI A1SJ71BR11 MITSUBISHI A1SJ71BR11. Input type: DC input, positive common end.
Input points: 4 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA.
Output form: transistor output, leakage type MITSUBISHI A1SJ71BR11.
Output points: 4 points.
OFF leakage current: 0.25mA.
Output protection function.
Rated load voltage / current: DC24V/0.5A.
External connection: 3 line /2 line type.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool.
3C-2V/5C-2V coaxial cable between the single bus PC network (control station / common station) / remote I/O network (remote master).
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 the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the ssystem work in a certain order A1SJ71BR11.
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.
