SP_RATE_UP SP_RATE_UP SP_RATE_UP SP_RATE_UP
Setpoint Rate Up Setpoint Rate Up Setpoint Rate Up Setpoint Rate Up
RW Ramp rate at which upward setpoint changes are acted on in
"Auto" mode, in PV units per second. If the ramp rate is set to
zero or the block is in a mode other than "Auto", then the
setpoint will be used immediately.
+INF
Setting:
0.0...+INF

Status Options Status Options Status Options Status Options
RW Options which the user may select in the block processing of
status.
No option selected
Setting:
• IFS if Bad IN: Set Initiate Fault State status in OUT if the
status of IN is "Bad".
• IFS if Bad CAS_IN: Set Initiate Fault State status in OUT if the
status of CAS_IN is "Bad".
• Use Uncertain as Good: If the status of IN is "Uncertain",
treat it as "Good" otherwise treat it as "Bad".
• Target to Man if Bad IN: Set the target mode to "Man" if the
status of the IN parameter is "Bad". This latches a PID block
into the "Man" state of the input ever goes "Bad".
• Target to next permitted mode if BAD CAS_IN

Tracking Input Tracking Input Tracking Input Tracking Input
Discrete Discrete Discrete Discrete
RW This discrete input is used to initiate external tracking of the
block output to the value specified by TRL_VAL.
Status RW Status of TRK_IN_D
Value RW Value of TRK_IN_D
TRK_SCALE TRK_SCALE TRK_SCALE TRK_SCALE
Tracking Scale Tracking Scale Tracking Scale Tracking Scale
RW The high and low scale values, engineering units code and
number of digits to the right of the decimal point associated
with TRK_VAL.
EU at 100% RW The engineering unit value which represents the upper end of
range of the associated block parameter.
100
EU at 0% RW The engineering unit value which represents the lower end of
range of the associated block parameter.
0
Units Index RW Device Description units code index for the engineering unit
descriptor for the associated block value.
Uninitialized
Setting:
All units are possible.
Decimal Point RW The number of digits to the right of the decimal point which
should be used by an interface device in displaying the
specified parameter.

Tracking Value Tracking Value Tracking Value Tracking Value
RW This input is used as the track value when external tracking is
enabled by TRK_IN_D.
Status RW Status of TRK_VAL
Value RW Value of TRK_VAL
UPDATE_EVT UPDATE_EVT UPDATE_EVT UPDATE_EVT
Update Event Update Event Update Event Update Event
R This alert is generated by any change to the static data.
Unacknowledged R A discrete enumeration which is set to "Unacknowledged"
when an alarm occurs, and set to "Acknowledged" by a write
from a human interface device or other entity which can
acknowledge that the alarm/event has been noticed.
Uninitialized
