  3. A programmable controller (PLC) has a microprocessor and controls the device through custom user programs. A PLC receives signals from the input device and decides to depend on the custom program to control the output device. Ladder Logic is a popular graphical programming language and is widely used for PLC programming in general. Omron PLC programming software, such as CX-Programmer, is used for programming on a PC and machine control.

    The PLC works in a very subtle way as the input and output devices are connected to the input and output section of the PLC. The user program determines how the output device works based on the condition of the input device. The status of the user program and the input and output devices are stored in the PLC’s internal memory.
