Automation Systems Question & Answers July 7, 2021 By WatElectronics This article lists 100+ Automation Systems MCQs for engineering students. All the Automation Systems Questions & Answers given below include a hint and wherever possible link to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on the Automation Systems topic. An automation system is used to automate the processes using electrical or electronic equipment like oil refineries, industrial equipment’s automatically simply by embedding compatible hardware and software of application-specific function. It is also called a process automation system (PAS). Some of the components used by PAS are sensors, networks, controllers, operating systems, which are an open standard distributed control system (DCS) that is based on a control system operated with a computer using plants or processes. DCS are applicable in power plants like a nuclear plant, water treatment, processes like metallurgical, etc. In some conditions PAS is considered as SCADA – supervisory control and data acquisition control system, is an architecture that comprises of networks data, peripheral devices like PLC – programable logic controller, PID – proportional integral derivative controller. SCADA is applicable in control systems like manufacturing, generation of a power system, ships, heat controllers, etc. the main disadvantage of SCADA is that it has network vulnerabilities. The advantage of using an automation system is that it reduces manpower and increases the reliability of automation systems with maximum efficiency. 1). Automation system is also called as _________.
