Control System engineers develop skills in specific control disciplines such as:advanced process control (APC);distributed control systems (DCS);programmable logic controllers (PLC);supervisory control and data acquisition (SCADA).The use of these disciplines will depend on the exact nature of individual job roles. In general, however, tasks and responsibilities can include:designing and developing new control systems;testing, maintaining, and modifying existing systems;analyzing data and presenting findings in written reports;managing operations;working collaboratively with design engineers, operation engineers, purchasers, and other internal staff;liaising with clients, suppliers, contractors, and relevant authorities (e.g. the Nuclear Decommissioning Authority);project management within cost and time-constrained environments;understanding and ensuring compliance with relevant health and safety regulations and quality standards;providing advice and consultancy support;purchasing equipment;writing computer software and test procedures;developing new business proposals.
