Why PLC Plays an Essential Role In Machine Control

A programmable logic controller (PLC) can be used as an electronic appliance or a device, primarily used across many industries to regulate and monitor building systems, production processes, and machine control. As contrary to PCs and smartphones, which perform multiple roles, a PLC is devised to carry out a single set of tasks, except with real-time constraints & with enhanced reliability and execution. All of this is transmitted through a unique HMI (human-machine interface).

To match the demands of hostile industrial environments, PLCs are designed to be extremely robust and well built, often capable of functioning under unfavorable conditions such as extreme temperatures, humidity, vibration, and noise.

PLCs importance in machine control can be further explained below:

Wind Turbine Operation

PLCs are being utilized to help make wind turbines more usable and experience negligible downtime. It’s necessary for wind turbines to have the right information regarding wind conditions or weather conditions in order to operate safely, as wind data is needed to register turbulence and safeguard the turbine. PLCs transform signals from wind velocity and direction sensors, enabling greater control over the wind turbines. The data or information transmitted from the PLCs are also used for statistical data analysis to ensure that failures can be detected before their occurrence.

 

Cement Manufacturing

PLCs also play an important role in cement manufacturing. This function involves stirring and blending various raw materials and compounds in a furnace. A PLC program makes sure that the specific quality and quantity of raw materials are used in this process.

The Smart Factory

The manufacturing process has become easier and smoother all credit goes to the Internet of Things (IoT) and intelligent automation. Despite the fast changes in technology, PLCs continue to play a critical and important role in the manufacturing process, acting as a datastore for all real-time decisions. For instance, a PLC transmits data, including sensor execution and other data, that can be integrated with cloud computing to show a comprehensive picture, i.e. a collection of “big data.” Analysis tools can then help managers to leverage resources, organize jobs, carry out logistics, manage supplier timing, and other functions that are important to hone more efficient manufacturing functions.

Virtual Modelling

Virtual modeling systems are essential in order to create an accurate floor design. By doing so, industrialists can enhance their functions across their entire value chain, from design & engineering to sales, production, and service. PLCs are used in virtual modeling to replicate a new piece of equipment’s performance after installation, allowing industrialists to make suitable adjustments for successful implementation at a negligible cost.
