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,
Acccording to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions A0J2CPU A0J2CPU.
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 A0J2CPU.
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 A0J2CPU MITSUBISHI A0J2CPU. Input type: DC input, positive public end / negative public end.
Input points: 16 points.
Enter the response time: 10ms the following.
Rated input voltage / current: DC24V/5mA.
Output form: transistor output, leakage type MITSUBISHI A0J2CPU.
Output points: 16 points.
OFF leakage current: 0.1mA.
Output protection function: No.
Rated load voltage / current: DC24V/DC24V/0.5A.
External connection: 1 line /1 line type.
A2C shape terminal.
Type of input and output terminal.
Shape and A2C input and output modules are identical (same mounting dimensions),
Machining and installing holes are not required.
Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input AC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load A0J2CPU.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
