SIMATIC. The S7-1500 (A), Comfort Panels (B), and ET 200 distributed I/O (D) are all part of
the SIMATIC automation family.
Q9: Which technology allows Siemens drives and PLCs to communicate seamlessly over
Industrial Ethernet?
• A. PROFIBUS only
• B. PROFINET [CORRECT]
• C. DeviceNet
• D. Modbus RTU only
Correct Answer: B
Rationale: PROFINET (B) is the Industrial Ethernet standard used by Siemens for real-time
communication between PLCs, HMIs, drives, and other automation devices. While PROFIBUS
(A) is still used, PROFINET is the modern standard. DeviceNet (C) and Modbus RTU (D) are
other fieldbus protocols not native to Siemens systems.
