The function of PID parameters is best described asA. placing the system in a safe condition during process upsets.
B. optimizing a control loop.
C. ensuring that specified components are properly calibrated.
D. ensuring that specified components are properly installed.
The parameters of a PID control loop do not factor into the physical installation or calibration of the loop. These are handled via other processes and procedures. The PID loop does not evaluate or drive a process to a safe state upon a process upset, but can be directed by other programming to change mode, set point, or output.
