Input unit (encoder, pulse generator) (NSD servo system)
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 MITSUBISHI GT15-75ABUSL.
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 GT15-75ABUSL
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 MITSUBISHI GT15-75ABUSL.
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 MITSUBISHI GT15-75ABUSL.
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.

Analog touch panel.
From the technical principle to distinguish the touch screen, can be divided into five basic types: vector pressure sensor touch screen, resistive touch screen, capacitive touch screen technology, infrared touch screen technology, surface acoustic wave touch screen technology.
Vector pressure sensing technology touch screen has been withdrawn from the stage of history;
Infrared touch screen technology and low price, but the frame is fragile, easy to produce light interference and surface distortion;
The design of capacitive touch screen is reasonable, but it is difficult to solve the problem of image distortion;
The touch screen positioning resiistor technology is accurate, but its price is high, and fear of vulnerability scratch;
The surface acoustic wave touch screen solves various defects of the touch screen in the past,
Clear and not easy to be damaged, suitable for vaarioous occasions,
The disadvantage is that the screen surface if there is water droplets and dust will make the touch screen become slow, or even work GT15-75ABUSL GT15-75ABUSL.
