Input points: 32 points.
Input voltage: DC12V/DC24V/AC12V/AC24V.
Current: 4mA (DC12V/AC12V), 8.5mA (DC24V/DC24V).
Response time: 30ms (DC12/24V) /35ms (AC12/24V).
16 points / a common end.
50 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 A171SCPU (SV13/22)(REAL MODE) Manual A171SCPU Programming Manual A171SCPU
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 A171SCPU (SV13/22)(REAL MODE) Manual A171SCPU Programming 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 A171SCPU (SV13/22)(REAL MODE) Manual A171SCPU Programming Manual.
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.
CPU the speed of executing instructions.
Time of instruction.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay. Input type: DC input, positive public end / negative public end.
Input points: 16 points.
Enter the response time: 10ms the following.
Rated input voltage / current: DC24V/5mA.
Output form: transistor output, leakage type.
Output points: 16 points.
OOFF leakage current: 0 A171SCPU (SV13/22)(REAL MODE) Manual A171SCPU Programming Manual. 1mA.
Output protection function: No.
Rated load voltage / current: DC24V/DC24V/0.5A.
External connection: 1 line /1 line type.
A2C shape terminal.
Type of input and output terminal A171SCPU (SV13/22)(REAL MODE) Manual A171SCPU Programming Manual.
Shape and A2C input and output modules are identical (same mounting dimensions),
Machining and installing holes are not required.
