China is the world''s biggest market for human mmachine interface,
But it is not the highest sales market in the world,
This shows that the low-end user interface in China has a large share of AY70.
In recent years, the rapid development of national brands, to take a low price and other strategies, is a massive attack on the low end of the market,
Has occupied the dominant position in the low-end market, has won the recognition of the majority of users AY70.
International brands are also gradually developing its economic products, in order to seize the share of the low-end market.
Therefore, in the low-end market steady,
The overall performance of the domestic human machine interface manufacturers showing a rapid growth of the state.
Output points: 16 points MITSUBISHI AY70.
Voltage: DC5/12V.
Output type: Sink type.
Response time: 1ms.
8 points / a common end.
20 point terminal station.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process MITSUBISHI AY70. 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 MITSUBISHI AY70.
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 performance to price ratio, a reasonable choice of PLC.
System program memory for storing system proggram,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation AY70.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
