Proportional/ Integral/Derivative (PID) Function
Block
Description
None Allows you to specify control strategy options. The supported control
options for the PID block are Track enable, Track in Manual, SP-PV Track
in Man, SP-PV Track in LO or IMAN, Use PV for BKCAL OUT, and Direct
Acting.
None The DV HI alarm data, which includes a value of the alarm, a timestamp
of occurrence, and the state of the alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the deviation high alarm
condition.
None The priority of the deviation high alarm.
None The DV LO alarm data, which includes a value of the alarm, a timestamp
of occurrence, and the state of the alarm.
EU of PV_SCALE
The setting for the alarm limit use to detect the deviation low alarm
condition.
None The priority of the deviation low alarm.
EU of PV_SCALE The error (SP-PV) used to determine the control action.
None Enables the use of feedforward calculations.
None The feedforward gain value. FF_VAL is multiplied by FF_GAIN before it
is added to the calculated control output.
None The high and low scale values, engineering units code, and number of
digits to the right of the decimal point associated with the feedforward
value (FF_VAL).
EU of FF_SCALE The feedforward control input value and status.
None The proportional gain value. This value cannot = 0.
None
Options for controlling access of host computers and local control pan-
els to operating, tuning, and alarm parameters of the block. Not used
by the device.
None The HI alarm data, which includes a value of the alarm, a timestamp of
occurrence, and the state of the alarm.
None The HI HI alarm data, which includes a value of the alarm, a timestamp
of occurrence, and the state of the alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the HI HI alarm condition.
None The priority of the HI HI Alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the HI alarm condition.
None The priority of the HI alarm.
EU of PV_SCALE The connection for the PV input from another block.
None
The LO alarm data, which includes a value of the alarm, a timestamp of
occurrence, and the state of the alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the LO alarm condition.
None The LO LO alarm data, which includes a value of the alarm, a timestamp
of occurrence, and the state of the alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the LO LO alarm
condition.
None The priority of the LO LO alarm.
