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.
Input points: 16 points.
Voltage: DC48V.
Current: 4mA.
Response time: 10ms.
8 points / a common end.
Positive / negative sharing.
20 point terminal station.
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 MITSUBISHI AJ71E71N-T.
Read only memory. Manufacturers use, content can not be changed, power does not disappear
AJ71E71N-T
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 MITSUBISHI AJ71E71N-T. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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 AJ71E71N-T.
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 MITSUBISHI Ethernet module.
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 MITSUBISHI Ethernet module.
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. 10BASE5/10BASE2
When communicating in the PLC network of MITSUBISHI,
There is no sense of difference and discontinuity in the network,
Can carry on the remote monitoring, modification, debugging and other work of data communication and program,
Without taking into account the level and type of network MITSUBISHI Ethernet module.
MELSECNET/H and CC-Link use the way of loop communication,
Periodically automatically send and receive messages,
Doess not require specialized data communication procedures,
Simple parameters can be set AJ71E71N-T.
MELSECNET/H and CC-Link are used to transmit and receive the broadcast mode,
This can be done on the network data sharing.
For the use of Etthernet, MELSECNET/H, CC-Link network,
Can set the network parameters and various functions, simple and convenient in the Developer GX software screen MITSUBISHI AJ71E71N-T.
