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 AJ65SBTCF1-32D PDF datasheet AJ65SBTCF1-32D
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. 5 slots.
Installation of the power unit can not be used for AnS QnAS/ series units installed AJ65SBTCF1-32D PDF datasheet .
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment.
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students AJ65SBTCF1-32D PDF datasheet .
PLC user program is designed according to the control system of the process control requirements,
PLC programming language through the preparation of specifications, in accordance with the actual needs of the use of the function to design MITSUBISHI AJ65SBTCF1-32D PDF catalog MITSUBISHI AJ65SBTCF1-32D PDF catalog.
As long as the user can master some kind of standard programming language,
To be able to use PLC in the control system,
To achieve a variety of automatic control functions. Cable connection and A7PU/A7HGP/A6GPP CPU,
Cable length 3 meters MITSUBISHI AJ65SBTCF1-32D PDF catalog.
Provide A7HGP-SET/A6GPP-SET. Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
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.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a measure of howw much the user application can store the number of indicators AJ65SBTCF1-32D datasheet.
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 llogical operation instructions each account for 1 words AJ65SBTCF1-32D PDF datasheet . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
