Right Answer: In PLC (Programmable Logic Controller) and DCS (Distributed Control System), mapping refers to the process of defining how input and output signals from field devices (like sensors and actuators) are assigned to specific addresses or variables in the control system. This allows the control system to correctly interpret and manage the data from these devices for monitoring and control purposes.
Right Answer: RPI (Requested Packet Interval) is the time interval at which a device sends data on a ControlNet network, while NUT (Network Update Time) is the maximum time allowed for the network to update all devices. If you increase the NUT, it can lead to longer delays in data updates across the network, potentially affecting real-time performance and responsiveness.
Right Answer: Sensors are devices that detect and respond to physical stimuli, such as temperature, pressure, or light, and convert that information into signals. Transducers, on the other hand, are devices that convert one form of energy into another.
For example, a temperature sensor measures temperature and produces an electrical signal (sensor), while a thermocouple converts temperature differences into a voltage (transducer).
Right Answer: **Difference between PLC and SCADA:**
- **PLC (Programmable Logic Controller):** A hardware device used for automation of industrial processes, controlling machinery on factory floors.
- **SCADA (Supervisory Control and Data Acquisition):** A software system that monitors and controls industrial processes at a higher level, providing data visualization and management.
**Merits of PLCs:**
- High reliability and durability.
- Real-time control and fast response times.
- Easy to program and modify.
- Suitable for complex control tasks.
**De-merits of PLCs:**
- Limited data handling and visualization capabilities.
- Higher initial cost for complex systems.
- Requires specialized knowledge for programming.
**Merits of SCADAs:**
- Centralized monitoring and control of multiple PLCs.
- Advanced data visualization and reporting capabilities.
- Remote access and control.
- Scalability for large systems.
**De-merits of SCADAs:**
- Higher complexity and cost.
- Vulnerability to cybersecurity
Right Answer: HMI (Human-Machine Interface) is a user interface that allows operators to interact with machines or systems, while SCADA (Supervisory Control and Data Acquisition) is a system that monitors and controls industrial processes, often using multiple HMIs to gather data and provide oversight.
Right Answer: Life is the condition that distinguishes living organisms from inorganic matter, characterized by growth, reproduction, functional activity, and continual change preceding death.
Right Answer: Supernatural power refers to abilities or forces that are beyond the natural laws of the universe, often attributed to divine beings, magic, or otherworldly entities.
Right Answer: I chose this firm because of its strong reputation in the industry, commitment to innovation, and opportunities for professional growth that align with my career goals.
Right Answer: Onsite projects are those where the work is done at the client's location, while offshore projects are conducted at a different location, often in another country, typically to take advantage of cost savings or specialized skills.
Right Answer: SCADA (Supervisory Control and Data Acquisition) is a system for remote monitoring and control of industrial processes, often over large distances. DCS (Distributed Control System) is used for controlling production systems within a localized area, focusing on continuous processes. HMI (Human-Machine Interface) is the user interface that allows operators to interact with machines and systems, displaying data and enabling control.
Right Answer: In quantity surveying, 'zero value' refers to items or work that are included in a project but do not have a cost associated with them, often because they are not expected to incur any expenses or are accounted for in other ways.
Right Answer: Engineering drawings are called blueprints because they were originally produced using a printing process that created white lines on a blue background, known as the blueprint process.
Ques:- Why people works on commission basis, where there is no fix income
Asked In :-
Right Answer: People work on a commission basis because it allows them to earn more based on their performance and sales. This can be motivating and rewarding for those who are confident in their abilities to generate business.
Right Answer: PLC (Programmable Logic Controller) is used for controlling machinery and processes with real-time operations. DCS (Distributed Control System) is used for controlling complex processes in large plants, providing centralized control with distributed elements. SCADA (Supervisory Control and Data Acquisition) is used for monitoring and controlling infrastructure and facility-based processes, often over large distances, providing data collection and visualization.
Right Answer: The Dirac delta function is a mathematical function that represents an idealized point mass or point charge, characterized by being zero everywhere except at a single point, where it is infinitely high, and integrates to one. Its Fourier transform is a constant function, meaning that it has equal amplitude across all frequencies. The importance of the Dirac delta function lies in its ability to simplify the analysis of systems in physics and engineering, particularly in signal processing and control systems, as it allows for the representation of impulses and point sources.
Right Answer: My landscape refers to the overall environment and context in which I work, including the projects I manage, the stakeholders involved, the resources available, and the challenges I face in project planning and execution.
Right Answer: Development length is the length of rebar required to be embedded in concrete to develop its full strength, while overlap length is the length of rebar that is overlapped and tied together to ensure continuity in reinforcement when two bars are joined.
