Computer connection function.
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc MITSUBISHI AJ71QLR21. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram AJ71QLR21
So far the system''s hardware electrical circuit has been determined.
Printer / peripheral device connection, BASIC language function.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc MITSUBISHI AJ71QLR21. .
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps. 10BASE-T.
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 AJ71QLR21 AJ71QLR21 MITSUBISHI.
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 AJ71QLR21 MITSUBISHI.
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 AJ71QLR21 MITSUBISHI. Input unit (upper / lower limit LS signal) (NSD servo system)
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.
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 control reqquirements,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ71QLR21.
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 AJ71QLR21.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
