Input points: 32 points.
Voltage: DC12/24V.
Current: 4/10mA.
Response time: 10ms.
8 points / a common end.
Negative utility.
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 A3NMACA0-UL Manual A3NMACA0-UL User's Manual A3NMACA0-UL
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 A3NMACA0-UL Manual A3NMACA0-UL User's Manual.
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 A3NMACA0-UL Manual A3NMACA0-UL 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. The A1SP60 pulse capture module is a 16 point DC24V input module,
Can be used as a general input module,
Can also be used as a pulse capture module,
Pulse capture ffunction makes the input signal width in the sequence can be as short as 0 A3NMACA0-UL Manual A3NMACA0-UL User's Manual. 5ms,
Once there is a pulse signal input, the state is memory,
A1SP60 to ensure that the control process at least once again to control the state of the memory of the operation,
Input can be set to 4 blocks,
Each block can be set to a general function or pulse capture function A3NMACA0-UL Manual A3NMACA0-UL User's Manual.
