PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control AJ65SBTB2-8T1 datasheet PDF catalog AJ65SBTB2-8T1 PDF datasheet.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control AJ65SBTB2-8T1
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity AJ65SBTB2-8T1 datasheet PDF catalog AJ65SBTB2-8T1 PDF datasheet.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal AJ65SBTB2-8T1 datasheet PDF catalog AJ65SBTB2-8T1 PDF datasheet.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing.
This requires the resolution of the analog unit and the standard electrical signal. Output points: 16 points.
Voltage: DC24/48V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 3ms.
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 selection,
Under the premise of meeting the control requirements,
Should consider the best performmance to price ratio, a reasonable choice of PLC AJ65SBTB2-8T1 datasheet PDF catalog AJ65SBTB2-8T1 PDF datasheet.
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 AJ65SBTB2-8T1 datasheet PDF catalog AJ65SBTB2-8T1 PDF datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
