A Programmable Logic Controller, or PLC, is a ruggedized computer used for industrial automation. These controllers can automate a specific process, machine function, or production line.
PLC systems receive information from connected sensors or input devices, process the data, and trigger outputs based on pre-programmed parameters. Depending on the inputs and outputs, PLC systems can monitor and record run-time data such as machine productivity or operating temperature, automatically start and stop processes, generate alarms if a machine malfunctions, and more. Programmable Logic Controllers are a flexible and robust control solution, adaptable to almost any application.
• I/O – The Programmable Control CPU stores and processes program data, but input and output modules connect the PLC system to the rest of the machine; these I/O modules are what provide information to the CPU and trigger specific results. I/Os are analog or digital; input devices might include sensors, switches, and meters, while outputs include - relays, lights, valves, and drives. Users can mix and match a PLC system I/O to get the proper configuration for their application.
• Communications – In addition to input and output devices, PLC systems might also need to connect with other kinds of systems - for example, users might want to export application data recorded by the PLC to a supervisory control and data acquisition (SCADA) system, which monitors multiple connected devices. A Programmable controller offers a range of ports and communication protocols to ensure the PLC system can communicate with these other systems.
• HMI – To interact with the PLC system in real time - users need an HMI or Human Machine Interface. These operator interfaces can be simple displays - with a text readout and keypad or large touchscreen panels more similar to consumer electronics; they enable users to review and input information to the PLC system in real time.
New advancements in Programmable controller features are constantly evolving. Anywhere the Internet of Things (IoT), Industry 4.0 programmable controllers are called upon to communicate data via Web browsers, connect to databases, and even to cloud data.
