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,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions MITSUBISHI A1SJ71AR21  Manual A1SJ71AR21 
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 MITSUBISHI A1SJ71AR21  Manual .
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 A1SJ71AR21  Manual . DC input points: 8 points.
Input voltage and current: 7mA, DC24V.
Input response time: 10ms.
8 point /1 a public side.
Positive pole sharing.
Output points: 8 points.
Output voltage and current: DC24V.
Output response time: 2ms.
8 point /1 a public side.
Output form: transistor output, leakage type.
40 point terminal station.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc..
MITSUBISHI PLC program simulation debbugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of thee program A1SJ71AR21  User's Manual A1SJ71AR21  User's Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
