PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work A970GOT-TBA-EU PDF A970GOT-TBA-EU PDF A970GOT-TBA-EU

Input voltage: DC12/24V.
Current: 3/7mA.
Response time: 10ms MITSUBISHI User's Manual.
Positive / negative sharing.
50 point terminal station.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well aas the user program to do the compiler to compile the process of interpretation A970GOT-TBA-EU Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear MITSUBISHI User's Manual.
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 performance to price ratio, a reasonable choice of PLC.
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 componeent image register are changed with the change of the execution of the program A970GOT-TBA-EU User's Manual.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A970GOT-TBA-EU Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
