The telephone line of the interface module is connected with the peripheral equipment.Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 60k.
Basic command processing speed (LD command) S:0.075.
PLC in the program execution stage: according to the order of the user program order to store the order of each instruction,
After the corresponding operation and processing, the result is written to the output status register,
The contents of the output status register are changed with the execution of the program MITSUBISHI A1SJ71E71-B5-S3 A1SJ71E71-B5-S3
Output refresh phase: when all instructions are executed,
The output status register is sent to the output latch in the output refresh stage,
And through a certain way (relay, transistor or transistor) output, drive the corresponding output equipment MITSUBISHI A1SJ71E71-B5-S3. 10BASE-T
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process MITSUBISHI A1SJ71E71-B5-S3.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program. Program memory capacity: 8k.
Input / output points: maximum 256 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage. Type of input: DC source.
Input points: 32 points.
Input voltage: DC24.
Input current: 7mA.
Connection mode: terminal row.
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,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions.
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.
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 floow 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 compllicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced A1SJ71E71-B5-S3 A1SJ71E71-B5-S3.
