MITSUBISHI A3ACPUR21-S1 Programming Manual (Fundamentals) PDF

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 A3ACPUR21-S1 PDF.
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 A3ACPUR21-S1
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 A3ACPUR21-S1 PDF.
Read only memory. Manufacturers use, content can not be changed, power does not dissappear A3ACPUR21-S1 Manual . CC-Link master / slave station.
PLC is the use of " sequential scanning, and constantly circulating " way to work A3ACPUR21-S1 PDF.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work MITSUBISHI Programming Manual MITSUBISHI Programming Manual.
