ENERGOPROJEKT ENTEL Interview Questions and Answers

SCADA is a centralized system used to monitor and control industrial processes, while DCS is a distributed system that allows for control at a local level.

• SCADA is used for monitoring and controlling processes in industries such as power plants, water treatment facilities, and manufacturing plants.

• DCS allows for control at a local level, with each control unit being responsible for a specific area of the process.

• SCADA systems typically have a centralized control room where op...read more

PLC is used for discrete control of machines, while DCS is used for continuous control of processes.

• PLC is typically used for controlling individual machines or processes in manufacturing, automotive, and packaging industries.

• DCS is commonly used in industries such as oil and gas, chemical, and power generation for controlling continuous processes.

• PLCs are more cost-effective for small to medium-sized applications, while DCSs are better suited for large-scale operations.

• PLCs ...read more

Logic gates are electronic devices that perform logical operations based on input signals.

• Logic gates are the building blocks of digital circuits.

• They take one or more binary inputs and produce a single binary output based on a specific logic function.

• The basic types of logic gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR gates.

• Each logic gate has a corresponding truth table that shows the output for all possible input combinations.

• For example, the truth table for an AN...read more
