Continuous Control Functions
PID CONTROL BLOCK
2-29
77 Setpoint Restart Value (SPRVI) ........................................................................................CWR
The setpoint restart value is a floating-point input used to determine the active setpoint when
the PID block performs its first RUN cycle.
NONE Attribute is not configured into the database.
value Fixed floating point value is Setpoint Restart value.
LSP Any floating-point variable is Setpoint Restart value.
78 Feedforward Compensation Input (FFCI)........................................................................CWR
The feedforward compensation input is a floating-point value that is added or multiplied to the
denormalized AUTO output of the PID algorithm.
NONE Attribute is not configured into the database.
value Fixed floating point value is Feedforward Compensation Input value.
LSP Any floating-point variable is Feedforward Compensation Input value.
79 External Feedback Input (EFBI)........................................................................................CWR
The external feedback input is used with the standard integral in the PID algorithm to provide
an anti reset-windup capability. If the external feedback input is not used, the limited output
value is used.
NONE Attribute is not configured into the database.
value Fixed floating point value is External Feedback Input value.
LSP Any floating-point variable is External Feedback Input value.
80 Track Command Input (TCI) .............................................................................................CWR
The track command input is used to put the PID loop in track. If the track command input
exists then the output track input must exist.
NONE Attribute is not configured into the database.
value Fixed discrete value is Track Command Input value.
LSP Usually Track Status of slave controller in a cascade loop is discrete
variable is Track Command Input value.
81 Setpoint Track Input (SPTI) ..............................................................................................CWR
The setpoint track input is copied to the active setpoint when the setpoint mode is set to
TRACK. This input must exist if setpoint tracking is enabled.
NONE Attribute is not configured into the database.
value Fixed floating point value is Setpoint Track Input value.
LSP Any floating-point variable is Setpoint Track Input value.
82 Output Track Input (OPTI) ................................................................................................CWR
The output track input is copied to the active output when the output mode is set to TRACK.
This input must exist if the track command input exists.
NONE Attribute is not configured into the database.
value Fixed floating point value is Output Track Input value.
LSP Any floating-point variable is Output Track Input value.
