MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of the electrical wiring diagram and wiring diagram.
Electrical interconnection diagram of each part of the design system AX80 datasheet PDF catalog AX80 PDF datasheet.
According to the construction drawings of the site wiring, and carry out a detailed inspection AX80
Because the program design and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced. Output points: 64 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink) AX80 datasheet PDF catalog AX80 PDF datasheet.
Response time: 2ms.
32 points / a common end.
40 pin connector.
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 AX80 datasheet PDF catalog AX80 PDF datasheet.
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 requirements,
Should consideer the best performance to price ratio, a reasonable choice of PLC AX80 datasheet PDF catalog AX80 PDF 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 AX80 datasheet PDF catalog AX80 PDF datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
