Top Applications of DCS and PLC Instrumentation Across Industries
DCS (Distributed Control Systems) and PLC (Programmable Logic Controllers) both serve as the backbone of many forms of industrial automation today. Both DCS and PLC technologies together provide the means to monitor, assess, and/or have complete operational command of complex processes quickly, accurately, reliably, and consistently. DCS and PLC instrumentation work together in many manufacturing plants, utilities, etc., to help provide an accurate means of increasing efficiency and productivity, as well as improving the safety of both equipment and personnel.
Manufacturing and Process Industries
PLCs are used extensively within the manufacturing industry to automate or make repetitive tasks easier to perform, such as product assembly, packaging, and material handling. The DCS systems would typically handle more continuous-type processes (e.g., chemical manufacturing, crude oil refining, etc.). Both forms of industrial automation provide the same benefits of maintaining the quality of products produced and reducing the potential for human error through increased operational efficiency. The sensors and control devices integrated into the industrial automation process allow manufacturers to monitor their manufacturing processes instantaneously and have the ability to perform very precise control over those same processes.
Energy and Power Generation
Today, power plants (including fossil fuel thermal, hydropower, and renewable energy sources) rely heavily on Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC). The two systems not only provide accurate control of turbine operation, regulate voltage levels, and support grid stability, but in combination, they improve energy efficiency, reduce downtime, and provide for safe operations in the high-risk field of power generation.
Oil, Gas, and Water Treatment Industries
In the oil and gas industry, PLCs control drilling equipment and pipelines, and DCS control refining processes. Similarly, in water wastewater treatment facilities, DCS and PLCs are employed to automate filter systems, chemical dosing systems, and distribution systems. Such implementations provide improved reliability of the system, compliance with regulatory requirements, and improvements in safety practices. Automation also allows for remote monitoring of equipment, thereby reducing human intervention in areas that are potentially dangerous to operate.
