output
The temperature measurement value (16 bit''signed binary): 2000 ~ 8500 A3NCPUP21
Zoom value (16 bit with symbol binary).
No program can perform conversion operations, scaling
Easy to use parameters to set the conversion operation and scaling, no need to create a dedicated program.
Therefore, it is helpful to reduce the development cost of the program and to reduce the program capacity A3NCPUP21.
High speed data sampling is not affected by the scan time.
The analog input module has the function of recording, which can be used to collect the analog quantity input data in the industrial application.
Can continuously collect data in a set period, each channel can store up to 10000 points of the recorded data.
In addition, the state of the state of any time and data in the program can be changed as a trigger,
To stop collecting data A3NCPUP21. The analog quantity input data can be stored and maintained before and after the trigger state through the function,
Easy to determine the occurrence of the phenomenon and the collection of test data. Such as motor testing equipment used in this function.
Control instructions from a programmable controller to a transducer and a power meter transmission test mode,
At the same time, the test data of the test motor is collected at the same time. Output points: 16 points.
Voltage: AC100 ~ 240V.
OFF leakage current: 3mA.
Output type: bidirectional controlled silicon.
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. 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.
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.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selectionn,
Under the premise of meeeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A3NCPUP21.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation A3NCPUP21.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
