RS-422 1 channel, RS-422/485 1 channel.
Transmission speed: 2 channel total is 115.2kbps.
Control layer /MELSECNET/10 (H) is the middle layer of the whole network system,
Control network which is convenient and high speed processing data transmission between PLC, CNC and other control equipment.
With its good real-time performance, simple network settings, no procedures of the network data sharing concept,
As well as the redundant circuit and so on, has obtained the very high market appraisal,
In the world is also one of the few.
And MELSECNET/H not only inherited the excellent characteristics of MELSECNET/10,
Further adapt to the needs of the market.
8 slots.
To install the power supply.
For Q4AR power duplex.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order MITSUBISHI AJ71QC24N-R4.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic
AJ71QC24N-R4
And the control principle is decentralized, centralized and hybrid control three.
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 AJ71QC24N-R4.
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 MITSUBISHI AJ71QC24N-R4.
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.
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. Adapter for mounting rails. I/O unit.Input points: 16 points.

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 conntrol requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ71QC24N-R4.
System program memory for storing system program,
