Question 61General Subjects - Assistant Engineer

The correct answer is A) Operator access to control functions among the various ROS locations differ depending on system configuration and need. This is correct because in a distributed automation system, the remote operating system (ROS) workstations are typically configured to provide different levels of access and control depending on their location and the specific operational requirements. The system design allows for tailoring the operator access and control capabilities of each ROS to match the responsibilities and needs of that particular work area. The other options are incorrect because they make blanket statements about the ROS designations or access levels, which may not accurately reflect the flexibility and customization inherent in a distributed automation system design.
