The Mitsubishi Q2ASCPU PLC has 512 I/O points, 8192 I/O data device points, 28k program capacity, and a basic instruction speed of 0.2 μs (LD command). During program execution, instructions are scanned sequentially, and results are written to the output status register, which updates continuously. After all instructions are executed, the output status register’s states are transferred to output latches in the output refresh phase, driving output devices via relays, transistors, or triacs.
