Question 1

Which communication protocol is most commonly used for real-time data exchange between PLCs and SCADA systems in industrial environments?

Accepted Answer

Modbus TCP

Answer

Modbus TCP is a widely adopted industrial protocol for real-time communication between PLCs and SCADA systems due to its simplicity and reliability.

Question 2

In a flexible manufacturing system (FMS), what is the primary role of the material handling system?

Accepted Answer

Transporting workpieces between workstations

Answer

The material handling system in an FMS moves workpieces between workstations automatically, enabling continuous and flexible production flow.

Question 3

What does the term 'dead band' refer to in process control systems?

Accepted Answer

A range of input values that produce no change in controller output

Answer

Dead band is the range of error values within which the controller takes no corrective action, preventing unnecessary actuator cycling.

Question 4

Which type of robot configuration offers the largest and most irregular work envelope?

Accepted Answer

Articulated (revolute) robot

Answer

Articulated robots with multiple rotary joints can reach around obstacles and access complex spatial positions, giving them the largest and most irregular work envelopes.

Question 5

In automated optical inspection (AOI), which imaging technique is commonly used to detect surface defects on printed circuit boards?

Accepted Answer

2D grayscale or color vision with pattern matching

Answer

AOI systems typically use 2D camera-based vision with grayscale or color imaging and pattern matching algorithms to detect solder defects, missing components, and misalignments on PCBs.
