SP_RATE_DN
The rate, in PV units per second, the setpoint can be moved downwards. If
the setpoint moves faster than SP_RATE_DN, the block acts as if the setpoint
is moving downwards at the maximum rate with a status bit that indicates
that it is limited.
SP_RATE_UP
The rate, in PV units per second, the setpoint can be moved upwards. If the
setpoint moves faster than SP_RATE_UP, the block acts as if the setpoint is
moving upwards at the maximum rate with a status bit that indicates that it
is limited.
ST_REV
ST_REV is incremented by one each time a static parameter is modified.
STATUS_OPTS
A collection of options that effects the status behavior of the block.
TableC-15 lists the status options.
Table C-15. Status Options
Option Meaning
IFS if Bad IN Set the status of the block output to initiate faultstate if the IN
parameter goes bad.
IFS if Bad CAS_IN Set the status of the block output to initiate faultstate if the
CAS_IN parameter goes bad.
Use Uncertain as Good Treat the Uncertain status on an input parameter as if it was
a Good status. Otherwise, Uncertain status is treated as bad.
Propagate Failure Forward If the status of the IN parameter is Bad::Device_Failure
or Bad::Sensor_Failure, propagate the failure to the OUT
parameter and do not generate an alarm.
Propagate Failure Backward If the status at BKCAL_IN or from the physical I/O channel is
bad, propagate it to BKCAL_OUT and do not generate an alarm.
Target to Manual if Bad IN Set the target mode of the block to Manual if the IN parameter
has a bad status.
Uncertain if Limited Produce an output status of Uncertain if the transducer
value is limited.
