Position Type PID Control (Disable Tracking for
primary loop/Enable Tracking from secondary
loop) (M+P_PIDP_EX_)

M+P_PIDP_EX_

This FB performs PID operations using process variable differential, inexact differential, and position type, and outputs the
result.
It also allows manipulated value bumpless switching and tracking from the secondary loop at a change of control mode.
