STATUS_OPTS (Faultstate, Limiting, Option)

A collection of options that affect the status behavior of the block.

Table B-13. 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 (i.e., at its high or low limit).

Bad if Limited

Set the output status to

Bad

if the transducer value is limited

(i.e., 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.
