3C-2V/5C-2V coaxial dual ring remote I/O network (remote I/O station).
Q mode.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program A1SJ71QLP21S PDF.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register A1SJ71QLP21S
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive AA1SJ71QLP21S PDF A1SJ71QLP21S Manual .
Semiconductor circuit with memory function.
System program memory and user memory.
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 A1SJ71QLP21S PDF.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
User memory: user program storage area and work data storage area.
Composed of random access memory (RAM). User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years MITSUBISHI User's Manual. 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 MITSUBISHI User's Manual.
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 A1SJ71QLP21S User's Manual.
MELSECNET/H and CC-Link are used to transmit and receive the broadcast mode,
This can be done on the network data sharing MITSUBISHI User's Manual.
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 A1SJ71QLP21S Manual .
