Programmable Logic Controllers (PLCs) are small computers that monitor inputs and outputs, making logic-based decisions for automated processes and/or machines, particularly in manufacturing environments.

PLCs are robust, reliable – and if implemented correctly – are easily understood by employees, allowing manufacturing operations to be monitored with incredible precision.

PLC-based automation allows for increased output, healthier systems and optimized revenue for manufacturers.

Because of this, PLCs will be an integral part of any manufacturing environment in the foreseeable future and must be factored into the design of any Industrial IoT solution.

A programmable logic controller (PLC), or programmable controller, like the one featured above, is an industrial digital computer which has been ruggedized and adapted for manufacturing processes. PLCs have been optimizing assembly lines, robotic devices, and many other activities that require high reliability control, ease of programming and process fault diagnosis.
