PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process A1SJ71PB92D datasheet PDF catalog A1SJ71PB92D PDF datasheet.
Programmable controller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions. 26 point line conversion adapter 1 line type 16 input CC-Link unit installation special connection conversion adapterInput points: 32 points A1SJ71PB92D datasheet PDF catalog A1SJ71PB92D PDF datasheet.
Voltage: DC12/24V.
Current: 2.5/5mA.
Response time: 0.2ms.
8 points / a common end.
Positive / negative sharing.
38 point terminal station.
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 requirements,
Should consider the best perrformance to price ratio, a reasonable choice of PLC A1SJ71PB92D datasheet PDF catalog A1SJ71PB92D 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 A1SJ71PB92D datasheet PDF catalog A1SJ71PB92D PDF datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
