Mitsubishi CPU Unit A1SCPU – High-Performance Programmable Logic Controller Module
Mitsubishi CPU Unit A1SCPU
Mitsubishi CPU unit A1SCPU:
Program memory capacity: 8k steps.
I/O points: up to 256.
A PLC scan cycle consists of three stages: input sampling, program execution, and output refresh.
During input sampling, the PLC sequentially reads the ON/OFF status or data from input terminals stored in the input latch, writes them into the corresponding input status registers (refreshing inputs), then closes the input port and proceeds to program execution.
Mitsubishi CPU unit A1SCPU
Program memory capacity: 8k steps.
Max I/O points: 256.
A PLC scan cycle consists of three stages: input sampling, program execution, and output refresh.
During the input sampling stage, the PLC sequentially reads the ON/OFF status or data from all input terminals temporarily stored in the input latch, writes them into the corresponding input status registers (refreshing the inputs), then immediately closes the input ports and proceeds to the program execution stage.
