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.
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 QJ71LP21-25
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.
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.
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. Input expansion board (DC24V 4)
(FX1S and FX1N host general). Input type: DC input, positive / negative public end.
Input points: 8 points.
Enter the response time: 0.2ms below, below 1.5ms, 5ms below, 10ms the following.
Rated input voltage / current: DC12V/7mA.
Output form: relay output.
Output points: 8 points.
OFF leakage current: -.
Output protection function: No.
Rated load voltage / current: DC24V/AC240V/0.5A.
External connection: 3 line /2 line type.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool.
