MITSUBISHI AJ65SBTB2N-16R PDF catalog AJ65SBTB2N-16R datasheet PDF datasheet

3C-2V/5C-2V coaxial cable single bus 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 AJ65SBTB2N-16R PDF datasheet.
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 AJ65SBTB2N-16R
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 AJ65SBTB2N-16R PDF datasheet.
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 AJ65SBTB2N-16R PDF datasheet.
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 and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Optical data communication line.
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.
User program storage capacity: it is a measure of how much the user application can store the number of indicators AJ65SBTB2N-16R PDF catalog.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words AJ65SBTB2N-16R PDF catalog. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
