8 channel analog input module.
This is a high density of 8 channel A/D components,
Can receive voltage and current input, with the installation of the inside of the cover plate switch,
The input type and range of each channel can be set up according to the application requirements:
12 bit resolution,
Automatic drift correction function,
0 A951GOT-QSBD SW4D5C-GOTR-PACKE compatible Extended/Option Functions Manual Manual A951GOT-QSBD Operating Manual A951GOT-QSBD 5msec/1 channel,
-10-0-10V or 0-20mA input. Input points: 32 points.
Voltage: DC24V.
Current: 8.5mA.
Response time: 10ms.
32 points / a common end.
Positive / negative sharing.
38 point terminal station.
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 A951GOT-QSBD SW4D5C-GOTR-PACKE compatible Extended/Option Functions Manual Manual A951GOT-QSBD Operating Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
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 A951GOT-QSBD SW4D5C-GOTR-PACKE compatible Extended/Option Functions Manual Manual A951GOT-QSBD Operating Manual. 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 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 A951GOT-QSBD SW4D5C-GOTR-PACKE compatible Extended/Option Functions Manual Manual A951GOT-QSBD Operating Manual.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A951GOT-QSBD SW4D5C-GOTR-PACKE compatible Extended/Option Functions Manual Manual A951GOT-QSBD Operating Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
