MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of the electrical wiring diagram and wiring diagram.
Electrical interconnection diagram of each part of the design system MITSUBISHI A3VTS.
According to the construction drawings of the site wiring, and carry out a detailed inspection A3VTS
Because the program design and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced. 10BASE-T.
For Q mode.
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 A3VTS.
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 A3VTS.
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 A3VTS MITSUBISHI. 26 point with the connection transformation adapter 16 type 1 point input CC-Link unit to install the special connection transformation adapterOutput points: 32 points A3VTS MITSUBISHI.
Voltage: DC24V.
OFF leakage current: 0.1mA.
Output type: bidirectional thyristor output (type sink).
Response time: 2ms.
32 points / a common end.
50 point terminal station.
With the surge absorber.
Each scanning process A3VTS MITSUBISHI. 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.
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.
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 controll requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A3VTS.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation MITSUBISHI A3VTS.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
