ISA CAP study guide
ISA CAP · Work through your exam, one topic at a time.
The ISA Certified Automation Professional (CAP) is a professional credential administered by the International Society of Automation for practitioners who specify, design, integrate, and maintain industrial automation and control systems. Qualification is based on a combination of technical education and documented automation work experience. Candidates holding a four-year technical degree need a minimum of five years - 7,500 documented hours - of automation work within the five years before applying; candidates with a two-year degree or no degree need ten years, or 15,000 hours, within the ten-year window. An associate degree in automation or a related technology counts as two years of experience, and passing the CAP Associate Recognition Program exam counts as one year. The ISA CAP study guide has 4 sections and about 1,065 words.
01Process Control and Instrumentation Fundamentals
Process control fundamentals start with the measurement chain: sensor, transmitter, signal conditioning, and controller. Know how a 4–20 mA transmitter maps a calibrated range, why live zero (4 mA) supports broken-wire detection, and how HART adds digital diagnostics without replacing the analog signal.

Safety instrumented systems are engineered around safety functions, not just devices. The safety lifecycle runs from hazard/risk assessment and allocation through design, verification, installation, validation, operation, proof testing, modification, and decommissioning.
261 words, about 1 min03Automation Project and Engineering Management
Automation project management connects scope, requirements, estimate, schedule, procurement, execution, and acceptance. Start with a clear basis of design and functional requirements; then build a work breakdown structure, responsibility matrix, deliverable register, and integrated schedule.
242 words, about 1 min04Systems Integration, Networks, and Digital/Data Infrastructure
Integration work spans protocols, networks, and data infrastructure. Understand the Purdue/ISA-95 hierarchy from field devices through control, supervisory, operations, enterprise, and external zones; segmentation and conduits protect control systems.
