What does SRP/CS stand for, in the context of robot safety?

• A. Safe Redundant Process Control System
• B. Safety Related Parts of the Control System
• C. Systematic Risk Prevention Circuitry
• D. Safe Response Protocol/Control Safety

Answer: (B)

The idea being tested is that SRP/CS refers to the portion of the robot safety system that actually delivers the safety function—the parts of the control system that are safety-related and contribute to risk reduction. In safety standards, SRP/CS stands for Safety Related Parts of the Control System. This includes components like safety sensors, safety logic (often in a safety PLC), and safety actuators and diagnostics—everything directly involved in stopping or preventing hazardous conditions.

That’s why this choice is the best match: it uses the established terminology found in standards such as ISO 13849-1, which defines the safety-related parts of the control system and distinguishes them from non-safety parts of the overall control system. The other options aren’t standard terms used in robot safety; they don’t reflect the recognized concept of the safety-related portion of the control system.
