2-degree-of-freedom PID Control and DUTY O/P
(Enable Tracking for primary loop)

(M+M_2PID_DUTY_T)

M+M_2PID_DUTY_T
This FB performs two-degree-of-freedom PID control and duty output combining the functions of M+P_IN, M+P_PHPL,
M+P_2PID_T, and M+P_DUTY into a single FB. The primary loop can be tracked.
