As shown in the illustrated block diagram for a distributed automation system, what statement is true concerning the units labeled "ROS" which are remote operating system workstations? EL-0096

Correct Answer: Option C — Operator access to control functions among the various ROS locations differ depending system configuration and need.

Distributed automation architectures assign remote operating system (ROS) workstations varying privilege levels. Operator access rights and control permissions are dynamically configured based on specific operational needs, watchstanding duties, and safety interlocks.
