Table C-3. 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 alarm is entered in the subcode field. The first
alarm to become active will set the Active status in the Status
parameter. As soon as the Unreported status is cleared by the
alarm reporting task, another block alarm 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 alarm is entered in the subcode field. The first alarm to
become active will set the Active status in the Status parameter.
As soon as the Unreported status is cleared by the alarm
reporting task, another block alarm 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.
Refer to the appropriate device manual for information about
the specific channels available in each device.
You must configure the CHANNEL parameter before you can
configure the XD_SCALE parameter. See “Analog Input block”
on page 73 .
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.
L_TYPE 16 None Linearization type. Determines whether the field value is used
directly (Direct) or is converted linearly (Indirect).
