STATUS_OPTS (Faultstate, Limiting, Option)
A collection of options that affect the status behavior of the block.
Table 4-22. 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 If set, blocks will treat the Uncertain status on an input
parameter as if it were a Good status. If clear, Uncertain
status is treated as Bad .
Propagate Failure Forward If the status of the IN parameter of the block is
Bad::Device_Failure or Bad::Sensor_Failure , the
failure will be propagated to the OUT parameter. No alarm
will be generated.
Propagate Failure Backward If the status at BKCAL_IN or from the physical I/O channel
is bad, the failure will be propagated to the BKCAL_OUT
parameter. No alarm will be generated.
Target to Manual if Bad IN Set the target mode of the block to Man if the IN parameter
has a bad status.
Uncertain if Limited For input or calculation blocks, the output status will be set
to
Uncertain if the transducer or calculated value is
limited (that is, at its high or low limit).
Bad if Limited Set the output status to Bad if the transducer value is limited
(that is, at its high or low limit).
Uncertain if Manual Mode Set the output status to Uncertain if the block is in Man
mode.
Do Not Select if Not Auto
Mode
Set the output status to Do Not Select if the block is not
in an actual mode of Auto , Cas , or RCas and not initializing.
This is useful for blocks upstream of the selector block.
Do Not Select if Not Cas
Mode
Set the output status to Do Not Select if the block is not
in an actual mode of Cas or RCas and is not initializing. This
is useful for blocks connected to a selector block.
