CC-Link (intelligent equipment station).
Twisted pair. Output points: 32 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
16 points / a common end.
38 point terminal station.
With the surge absorber.
Each scanning process. Focus on the input signal sampling A1SJ71QLR21 Hardware Manual A1SJ71QLR21 User's Manual. Focus on the output signal to refresh A1SJ71QLR21
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 A1SJ71QLR21 Hardware Manual A1SJ71QLR21 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 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 A1SJ71QLR21 Hardware Manual A1SJ71QLR21 User's Manual.
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.
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. Manufacturers use, content can not be changed, power does not disappear. Input type: DC input, positive public end / negative public end A1SJ71QLR21 Hardware Manual A1SJ71QLR21 User's Manual.
Input points: 16 points.
Enter the response time: 10ms the following.
Rated input voltage / current: DC24V/7mA.
External connection: 2 wire.
Type of input and output termminal A1SJ71QLR21 Hardware Manual A1SJ71QLR21 User's Manual.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module.
