RS-232 1 channel.
RS-422/485 1 channel.
Transfer speed: 0.3-19.2kbps.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive AJ71QE71N-B2 PDF AJ71QE71N-B2
Semiconductor circuit with memory function.
System program memory and user memory.
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.
Read only memory AJ71QE71N-B2 PDF. Manufacturers use, content can not be changed, power does not disappear. 5 slots.
Can be installed in the power supply unit for AnS series units installed QnAS/.
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 AJ71QE71N-B2 PDF.
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.
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.
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. Output points: 32 points.
Voltage: AC100 ~ 240V.
OFF leakage current: 3mA.
Output type: bidirectional controlled silicon.
Response time: 0.5Hz+1ms.
8 points / a common end.
38 point terminal station.
With short circuit protection.
With the surge absorber.
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requiirements,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ71QE71N-B2 datasheet.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation AJ71QE71N-B2 datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
