Output points: 16 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
8 points / a common end.
20 point terminal station.
With short circuit protection.
With the surge absorber.
Each scanning process. Focus on the input signal sampling A1SX10 Manual A1SX10 User's Manual. Focus on the output signal to refresh.
Input refresh process A1SX10 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 A1SX10 Manual A1SX10 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 A1SX10 Manual A1SX10 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. Multi axis positioning controller.
Coaxial data communication line function.
Program capacity: Max 60K step.
Input / output points: 1920 points.
PLC commonly used in memorry are EPROM, EEPROM and with lithium battery powered RAM A1SX10 Manual A1SX10 User's Manual.
General micro and small PLC storage capacity is fixed, between 1~2KB.
How much memory is occupied by a user application is related to many factors,
Such aas I/O points, control requirements, computing processing, program structure, etc A1SX10 Manual A1SX10 User's Manual. .
So it can only be roughly estimated before the program is designed.
