The CPU executes the program that defines the logic and sequence of operations for the process. The I/O modules connect the CPU to sensors and actuators that monitor and control the physical variables of the process. The communication modules enable data exchange between the PLC and other devices or networks. The MMC card stores the program and data of the PLC.

The program can also be uploaded from the MMC card to a computer for backup or modification purposes.
