Global Programmable Logic Controller (PLC) Market accounted for US$ 11.21 billion in 2020 and is estimated to be US$ 17.76 billion by 2030 and is anticipated to register a CAGR of 4.8%. The major computing system that regulates automated machines is the Programmable Logic Controller (PLC). The technology also detects and warns the technician to any weaknesses or problems. Because of their small size, PLC systems are preferred over older systems like as relays and switch boxes. Another benefit of PLCs is their multi-functionality, which stems from their programmable nature, which allows them to be utilized for a variety of tasks depending on the application. Hardware, software, and services make up the PLC. The CPU module, the power supply, and the I/O modules are the major components of the PLC's fundamental architecture.
