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 A3ACPUP21-S3 Common Instructions Manual A3ACPUP21-S3 Programming Manual A3ACPUP21-S3
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 A3ACPUP21-S3 Common Instructions Manual A3ACPUP21-S3 Programming Manual .
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 A3ACPUP21-S3 Common Instructions Manual A3ACPUP21-S3 Programming Manual .
