Dual Safety Check (DCS) includes Emergency Stop Control.

• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

The key idea is that a Dual Safety Check design uses two independent safety paths so a fault in one path can’t allow unsafe operation. An Emergency Stop control is the primary human-initiated mechanism to bring a robot or cell to an immediate halt, so it belongs in this dual-path safety framework. Including the E-stop ensures there is a guaranteed, hard stop accessible to the operator, and it is wired or integrated so that pressing it affects both safety channels or is recognized by the safety logic as a stop command no matter what state the other parts of the system are in. This alignment preserves the purpose of having two safety checks: a single fault won’t defeat the ability to stop safely. Therefore, the statement is true.
