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

M+P_PIDP_EX_T_

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 primary loop and secondary loop at a change of
control mode.
