™
CHANNEL
: The number of the logical hardware channel
that is connected to this I/O block. (This information
defines the transducer to be used going to or from the phys-
ical world).
L_TYPE
: Determines if the values passed by the transducer
block to the AI block may be used directly (Direct), or if
the value is in different units and must be converted linearly
(Indirect), using the input range defined for the transducer
and the associated output range.
LOW_CUT
: Limit used in square root processing.
PV_FTIME
: Time constant of a single exponential filter for
the PV, in seconds.
FIELD_VAL
: Raw value of the field device in % of PV
range, with a status reflecting the Transducer condition
before signal characterization (L_TYPE) or filtering
(PV_FTIME).
UPDATE_EVT
: This alert is generated by any change to
the static data.
BLOCK_ALM
: The block alarm is used for all configura-
tion, hardware, or system problems in the block.
ALARM_SUM
: The current alert status, unacknowledged
states, unreported states, and disabled states of the alarms
associated with the function block.
ACK_OPTION
: Selection of whether alarms associated
with the function block will be automatically acknowledged.
ALARM_HYS
: Amount the PV must return within the
alarm limits before the alarm condition clears. Alarm hys-
teresis expressed as a percent of the span of the PV.
HI_HI_PRI
: Priority of the high-high alarm.
HI_HI_LIM
: The setting for high-high alarm in engineer-
ing units.
HI_PRI
: Priority of the high alarm.
HI_LIM
: The setting for high alarm in engineering units
LO_PRI
: Priority of the low alarm.
LO_LIM
: The setting for low alarm in engineering units.
LO_LO_PRI
: Priority of the low-low alarm.
LO_LO_LIM
: The setting for low-low alarm in engineering
units.
HI_HI_ALM
: The status for high-high alarm and its associ-
ated time stamp.
HI_ALM
: Status for high alarm and associated time stamp.
LO_ALM
: Status for low alarm and associated time stamp.
