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

M+M_PIDP_EX_

This FB performs position type PID control combining the functions of M+P_IN, M+P_PHPL, and M+P_PIDP_EX_ into a
single FB.
It also allows manipulated value bumpless switching and tracking from the secondary loop at a change of control mode.
