Preview Questions Control Systems Engineer | Role Specific Skill

Question 1: How do you incorporate safety instrumented systems (SIS) into control system design for a petrochemical facility?

Which action should you take?

Choose only one option

Design the SIS as an independent, dedicated system that meets safety standards such as IEC 61511, ensuring it functions properly in case of process control failure

Exclude SIS in favor of manual control systems

Focus only on process control and ignore safety

Combine the SIS with process control without considering safety standards

Question 2: What would be the effect of setting the integral (I) term too high in a PID controller in a chemical process?

Which action should you take?

Choose only one option

It would make the system more responsive and accurate

It could result in slow response time and overshoot due to excessive correction

It would stabilize the system by reducing oscillations

It would eliminate the steady-state error immediately

Question 3: In process automation, how can you handle emergency shutdowns in chemical plants?

Which action should you take?

Choose only one option

Ignore emergency shutdowns as they are unnecessary

Handle emergency shutdowns manually

Design and implement automatic emergency shutdown systems that trigger in the event of critical process deviations or safety risks

Skip emergency shutdown protocols for faster production

Question 4: How do you ensure real-time process automation in a chemical plant while maintaining system integrity?

Which action should you take?

Choose only one option

Use distributed control systems (DCS) with redundancy and local processing

Depend solely on human control and monitoring

Use manual overrides for critical operations

Use a centralized control system that processes data from all sensors

Question 5: When designing a control system for a distillation column, how do you account for the non-linearity of the process?

Which action should you take?

Choose only one option

Use linear controllers for simplicity

Implement model predictive control (MPC) to adjust for non-linearities

Design a purely manual control system

Use PID controllers with fixed parameters

Question 6: What is the primary role of a SCADA system in maintaining the operational safety of a petrochemical plant?

Which action should you take?

Choose only one option

Enabling manual overrides for all automated systems

Recording the operational history for future reference

Continuous monitoring of critical parameters and providing real-time alarms to prevent unsafe conditions

Preventing unauthorized access to the control network
