Cable length: 0.7 meters.
Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable. Input points: 32 points.
Voltage: DC12/24V A951GOT-QSBD-B Hardware Manual A951GOT-QSBD-B User's Manual.
Current: 2.5/5mA.
Response time: 10ms A951GOT-QSBD-B
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 A951GOT-QSBD-B Hardware Manual A951GOT-QSBD-B User's Manual.
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 A951GOT-QSBD-B Hardware Manual A951GOT-QSBD-B User's Manual.
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 A951GOT-QSBD-B Hardware Manual A951GOT-QSBD-B User's Manual.
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 A951GOT-QSBD-B Hardware Manual A951GOT-QSBD-B User's Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
