Bad
Sensor failure
Bad
Not Connected - Set if this input is required to be connected
and is not connected.
Bad
Configuration Error - Set if the value is not useful because
there is some inconsistency regarding the parameterization
or configuration, depending on what a specific manufacturer
can detect.
Bad
non-specific - There is no specific reason why the value is
bad. Used for propagation.
Bad
Process related - Substitute value
Bad
Process related - No maintenance
Uncertain
Maintenance demanded
Uncertain
Simulated value - Set when the process value is written by
the operator while the block is in manual mode.
Uncertain
Sensor calibration
Uncertain
Configuration error
Uncertain
Sub-normal
Uncertain
Engineering Unit Range Violation - Set if the value lies outside
of the set of values defined for this parameter. The Limits
define which direction has been exceeded.
Uncertain
Sensor conversion not accurate
Uncertain
Substitute (constant)
Uncertain
Process related - No maintenance
Uncertain
Initial Value - Value of volatile parameters during and after
reset of the device or of a parameter.
Uncertain
Substitute value - Predefined value is used instead of the
calculated one. This is used for fail safe handling.
Uncertain
Last Usable Value - Whatever was writing this value has
stopped doing so. This is used for fail safe handling.
Uncertain
Non-specific - There is no specific reason why the value is
uncertain.
Good
Initiate Fail Safe (IFS) - The value is from a block that wants
(Cascade
its downstream output block (e.g. AO) to go to Fail Safe.
)
Good
Local Override (LO) - The value is from a block that has been
(Cascade
locked out by a local key switch or is a Complex AO/DO with
)
interlock logic active. The failure of normal control must be
propagated to a function running in a host system for alarm
and display purposes. This also implies "Not Invited".
Good
Do Not Select (DNS) - The value is from a block which should
(Cascade
not be selected, due to conditions in or above the block.
)
Good
Not Invited (NI) - The value is from a block which does not
(Cascade
have a target mode that would use this input.
)
