MITSUBISHI A2NCPUP21-S4 Common Instructions Manual A2NCPUP21-S4 Programming Manual

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 heat protection.
With short circuit protection.
With the surge absorber.
Each scanning process. Focus on the input signal sampling A2NCPUP21-S4 Common Instructions Manual A2NCPUP21-S4 Programming Manual . Focus on the output signal to refresh A2NCPUP21-S4
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 A2NCPUP21-S4 Common Instructions Manual A2NCPUP21-S4 Programming 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 A2NCPUP21-S4 Common Instructions Manual A2NCPUP21-S4 Programming 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. I/O slots: 5 slots.
Could you install the power module.
Outline dimension: 315*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
The choice of any type of substrate depends on the total DC5V ccurrent consumption and the power supply on the CPU main substrate A2NCPUP21-S4 Common Instructions Manual A2NCPUP21-S4 Programming Manual .
If the total demand is less than the power output, no additional power supply,
Then you can choose a more ecconomical expansion board A2NCPUP21-S4 Common Instructions Manual A2NCPUP21-S4 Programming Manual .
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection.
