D-20HC | MITSUBISHI parts D-20HC

10BASE5.
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.
MELSECNET/H and CC-Link use the way of loop communication,
Periodically automatically send and receive messages,
Does not require specialized data communication procedures,
Simple parameters can be set MITSUBISHI D-20HC D-20HC
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 Ethernet, MELSECNET/H, CC-Link network,
Can set the network parameters and various functions, simple and convenient in the Developer GX software screen MITSUBISHI D-20HC. Input points: 32 points.
Voltage: DC24V.
Current: 8.5mA.
Response time: 10ms.
32 points / a common end.
Positive / negative sharing.
38 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 D-20HC.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
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 D-20HC MITSUBISHI.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference D-20HC MITSUBISHI. 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 D-20HC MITSUBISHI. 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.
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 commponent image register are changed with the change of the execution of the program D-20HC.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling MITSUBISHI D-20HC.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
