RS-232 2 channel.
Transmission speed: 2 channels.
At the same time the use of 115.2kbps may.
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.
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 A1SJ71AT21B
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 MITSUBISHI A1SJ71AT21B.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line.
Each scanning process. Focus on the input signal sampling MITSUBISHI A1SJ71AT21B. 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 cappacity: it is a measure of how much the user application can store the number of indicators A1SJ71AT21B.
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 lloggical operation instructions each account for 1 words A1SJ71AT21B. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
