Loop tag
The following FBs perform loop control processing including ratio control, various PID controls, two-position (on/off) control,
three-position (on/off) control, program setter, and loop selector.
■Velocity Type PID Control (Enable Tracking for primary loop)
Function block symbol Processing details
M+M_PID_T Performs velocity type PID control combining the functions of M+P_IN, M+P_PHPL, M+P_PID_T,
and M+P_OUT1 into a single FB. The primary loop can be tracked.
■Velocity Type PID Control (Disable Tracking for primary loop)
Function block symbol Processing details
M+M_PID Performs velocity type PID control combining the functions of M+P_IN, M+P_PHPL, M+P_PID, and
M+P_OUT1 into a single FB.
■Velocity Type PID Control and DUTY Output (Enable Tracking for primary loop)
Function block symbol Processing details
M+M_PID_DUTY_T Performs velocity type PID control and duty output combining the functions of M+P_IN,
M+P_PHPL, M+P_PID_T, and M+P_DUTY into a single FB. The primary loop can be tracked.
■Velocity Type PID Control and DUTY Output (Disable Tracking for primary loop)
Function block symbol Processing details
M+M_PID_DUTY Performs velocity type PID control and duty output combining the functions of M+P_IN,
M+P_PHPL, M+P_PID, and M+P_DUTY into a single FB.
■2-degree-of-freedom PID Control (Enable Tracking for primary loop)
Function block symbol Processing details
M+M_2PID_T Performs two-degree-of-freedom PID control combining the functions of M+P_IN, M+P_PHPL,
M+P_2PID_T, and M+P_OUT1 into a single FB. The primary loop can be tracked.
■2-degree-of-freedom PID Control (Disable Tracking for primary loop)
Function block symbol Processing details
M+M_2PID Performs two-degree-of-freedom PID control combining the functions of M+P_IN, M+P_PHPL,
M+P_2PID, and M+P_OUT1 into a single FB.
■2-degree-of-freedom PID Control and DUTY O/P (Enable Tracking for primary loop)
Function block symbol Processing details
M+M_2PID_DUTY_T 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.
■2-degree-of-freedom PID Control and DUTY O/P (Disable Tracking for primary loop)
Function block symbol Processing details
M+M_2PID_DUTY Performs two-degree-of-freedom PID control and duty output combining the functions of M+P_IN,
M+P_PHPL, M+P_2PID, and M+P_DUTY into a single FB.
■2-degree-of-freedom Advanced PID Control (Enable Tracking for primary loop)
Function block symbol Processing details
M+M_2PIDH_T_ Performs two-degree-of-freedom PID control combining the functions of M+P_IN, M+P_PHPL,
M+P_2PIDH_T_, and M+P_OUT3_ into a single FB with PV/MV correction. The primary loop can
be tracked.
■2-degree-of-freedom Advanced PID Control (Disable Tracking for primary loop)
Function block symbol Processing details
M+M_2PIDH_ Performs two-degree-of-freedom PID control combining the functions of M+P_IN, M+P_PHPL,
M+P_2PIDH_, and M+P_OUT3_ into a single FB with PV/MV correction.
