Table J-1: Definitions of Analog Input Function Block System Parameters
Parameter Index Number Units Description
ACK_OPTION 23 None Used to set auto acknowledgment of alarms.
ALARM_HYS 24 Percent The amount the alarm value must return within the alarm limit
before the associated active alarm condition clears.
ALARM_SEL 38 None Used to select the process alarm conditions that will cause the
OUT_D parameter to be set.
ALARM_SUM 22 None The summary alarm is used for all process alarms in the block. The
cause of the alert is entered in the subcode field. The first alert to
become active will set the Active status in the Status parameter. As
soon as the Unreported status is cleared by the alert reporting task,
another block alert may be reported without clearing the Active
status, if the subcode has changed.
ALERT_KEY 04 None The identification number of the plant unit. This information may
be used in the host for sorting alarms, etc.
BLOCK_ALM 21 None The block alarm is used for all configuration, hardware, connection
failure or system problems in the block. The cause of the alert is
entered in the subcode field. The first alert to become active will set
the Active status in the Status parameter. As soon as the
Unreported status is cleared by the alert reporting task, another
block alert may be reported without clearing the Active status, if
the subcode has changed.
BLOCK_ERR 06 None This parameter reflects the error status associated with the
hardware or software components associated with a block. It is a bit
string, so that multiple errors may be shown.
CHANNEL 15 None The CHANNEL value is used to select the measurement value.
You must configure the CHANNEL parameter before you can
configure the XD_SCALE parameter.
FIELD_VAL 19 Percent The value and status from the transducer block or from the
simulated input when simulation is enabled.
GRANT_DENY 12 None Options for controlling access of host computers and local control
panels to operating, tuning, and alarm parameters of the block. Not
used by device.
HI_ALM 34 None The HI alarm data, which includes a value of the alarm, a timestamp
of occurrence and the state of the alarm.
HI_HI_ALM 33 None The HI HI alarm data, which includes a value of the alarm, a
timestamp of occurrence and the state of the alarm.
HI_HI_LIM 26 EU of
PV_SCALE
The setting for the alarm limit used to detect the HI HI alarm
condition.
HI_HI_PRI 25 None The priority of the HI HI alarm.
HI_LIM 28 EU of
PV_SCALE
The setting for the alarm limit used to detect the HI alarm
condition.
HI_PRI 27 None The priority of the HI alarm.
IO_OPTS 13 None Allows the selection of input/output options used to alter the PV.
Low cutoff enabled is the only selectable option.
