Output points: 16 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
All points of independence.
38 point terminal station.
With the surge absorber.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh A975GOT-TBD-B Connection System Manual Manual A975GOT-TBD-B User's Manual.
Input refresh process A975GOT-TBD-B 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 A975GOT-TBD-B Connection System Manual Manual A975GOT-TBD-B User's 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 A975GOT-TBD-B Connection System Manual Manual A975GOT-TBD-B 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. Enter 32 points.

Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input ssequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A975GOT-TBD-B Connection System Manual Manual A975GOT-TBD-B User's Manual.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A975GOT-TBD-B Connection System Manual Manual A975GOT-TBD-B User's Manual.
And the control principle is decentralized, centralized and hybrid control three.
