As shown in figure "B" of the illustrated block diagram of a central operating system configured for supervisory control, which statement is true concerning the block "COMPUTER" with respect to closed-loop control processes? Illustration EL-0094

Correct Answer: Option C — The computer provides the set point input data to the analog controllers, but the analog controllers actually control the closed-loop processes.

In supervisory control configurations, the computer acts as a master controller that calculates and transmits set point values to local analog controllers. These analog controllers maintain the actual closed-loop process, ensuring stability and providing a reliable control layer that functions independently of the supervisory computer.
