HKIE Professional Assessment - Control, Automation & Instrumentation Discipline study guide
HKIE Professional Assessment - Control, Automation & Instrumentation Discipline · Work through your exam, one topic at a time.
The HKIE Professional Assessment in the Control, Automation and Instrumentation (CAI) discipline is the route by which engineers in Hong Kong demonstrate that they can practise at professional level in this field. It is aimed at graduates working in process control, industrial automation, instrumentation and safety-related systems who are ready to be assessed against the standard of a chartered-level engineer. The HKIE Professional Assessment - Control, Automation & Instrumentation Discipline study guide has 9 sections and about 4,781 words.
01Control Systems Theory and Design
Control Systems Theory and Design tests how you model a process, choose a control structure, demonstrate stability and tune a loop that remains robust when the plant changes. Questions often combine block-diagram algebra with commissioning reality: a correct formula is not enough if the answer ignores dead time, valve dynamics or sampling.
432 words, about 2 min02Process Instrumentation and Measurement
Process Instrumentation and Measurement tests selection, installation, calibration and interpretation of field instruments. The exam favours practical loop questions: a transmitter is only correct if its range, accuracy, wiring and process connection suit the application.
402 words, about 2 min03Industrial Automation
Industrial Automation tests how discrete, continuous and batch operations are mechanised and integrated. The exam expects you to select sensing and actuation, structure a control hierarchy and judge whether an automated line meets its throughput and quality targets.
392 words, about 2 min04PLC/SCADA and DCS
PLC/SCADA and DCS tests how control logic is executed, how operators interact with the plant and how alarms and historical data are managed. The exam distinguishes PLC/SCADA architecture from integrated DCS architecture and probes scan-time, alarm and redundancy behaviour.
395 words, about 2 min05Safety Instrumented Systems and Functional Safety
Safety Instrumented Systems and Functional Safety tests whether you can specify, design, verify and maintain a safety instrumented function independently of the basic control system. The exam centres on IEC 61508 and IEC 61511, SIL determination, PFD/PFH calculation and the safety lifecycle.
393 words, about 2 min06Fieldbus, Industrial Networks and Cybersecurity
Fieldbus, Industrial Networks and Cybersecurity tests how field devices, controllers and supervisory systems communicate, and how those networks are segmented and defended. The exam expects protocol knowledge plus IEC 62443-style security reasoning, not just IT firewall rules.
382 words, about 2 min07Control Valves, Actuators and Final Elements
Control Valves, Actuators and Final Elements tests the part of the loop that actually changes the process. The exam focuses on sizing, characteristic selection, actuation, fail-safe action and the practical faults that make a well-tuned controller perform badly.
401 words, about 2 min08Building Automation and Environmental Control
Building Automation and Environmental Control tests HVAC plant control, indoor environmental quality, energy performance and integration with fire and life-safety systems. The exam expects psychrometric reasoning and sequence-level control knowledge, not just BMS point lists.
395 words, about 2 min09Project Engineering
Project Engineering tests how instrumentation and control work is scoped, scheduled, costed, commissioned and handed over. The exam favours earned-value, interface and commissioning scenarios rather than generic project-management definitions.
