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
A
The computer provides the set point input data to the analog controllers, but the analog controllers actually control the closed-loop processes.
B
The computer has no role in the various closed-loop control processes regardless of the control mode.
C
