Rationale: TIA Portal (Totally Integrated Automation Portal) (B) is the current engineering
framework for SIMATIC S7-1200, S7-1500, and related products. It provides integrated
configuration, programming, and diagnostics. STEP 7 Classic (A) was used for S7-300/400,
WinCC flexible (C) was for HMI configuration, and SIMOTION Scout (D) is for motion control.
Q9: Which business segment would provide solutions for building automation and fire safety?
, A. Digital Industries
B. Smart Infrastructure [CORRECT]
C. Mobility
D. Energy
Correct Answer: B
Rationale: Smart Infrastructure (B) encompasses building technologies including building
automation, fire safety, and security systems. Digital Industries (A) focuses on factory
automation, Mobility (C) on transportation, and Energy is not one of the current primary
segments (it was reorganized into Smart Infrastructure).
Q10: The SIMATIC IPC product line refers to:
A. Industrial PCs [CORRECT]
B. Input/output modules
C. Intelligent power controllers
D. Industrial process controllers
Correct Answer: A
Rationale: SIMATIC IPC (Industrial PC) (A) refers to ruggedized computer hardware designed
for industrial environments, including panel PCs, box PCs, and rack PCs. These serve as HMI
platforms, data servers, or controllers for PC-based automation.
SECTION 2: PLC FUNDAMENTALS (Questions 11-25)
Q11: During a PLC scan cycle, what is the correct sequence of operations?
A. Execute program, read inputs, write outputs
B. Read inputs, execute program, write outputs [CORRECT]
C. Write outputs, read inputs, execute program
D. Execute program, write outputs, read inputs
Correct Answer: B
Rationale: The PLC scan cycle follows: (1) Read inputs (update process image input table), (2)
Execute program (process logic using input data), (3) Write outputs (update process image output
table to physical outputs) (B). This sequential processing ensures deterministic behavior and
consistent data during program execution.
