MITSUBISHI AJ71LP21GE Reference Manual (PLC to PLC network) PDF

Three slots in one side.
Power supply unit.
Q4AR duplex system.
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 AJ71LP21GE PDF.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic AJ71LP21GE
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh AJ71LP21GE PDF.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh AJ71LP21GE PDF.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scaan cycle is determined by the three AJ71LP21GE Manual .
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling MITSUBISHI Reference Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation MITSUBISHI Reference Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. Applicable model: A956WGOT.2 channels.
50kpps.
Count input signal: DC5/12/24V.
External input: DC5/12/24V.
Output: Transistor (open collector) 0.5A DC12/24V.
Output: DC12/24V, 0.3A MITSUBISHI Reference Manual.
47 point terminal station.
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHII PLC,
To determine the I/O PLC points AJ71LP21GE Reference Manual.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book AJ71LP21GE Manual .
