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. 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.
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), is converted linearly (Indirect), or is converted with the square root
(Indirect Square Root).
LO_ALM 35 None The LO alarm data, which includes a value of the alarm, a timestamp of
occurrence and the state of the alarm.
LO_LIM 30 EU of PV_SCALE The setting for the alarm limit used to detect the LO alarm condition.
LO_LO_ALM 36 None The LO LO alarm data, which includes a value of the alarm, a timestamp of
occurrence and the state of the alarm.
LO_LO_LIM 32 EU of PV_SCALE The setting for the alarm limit used to detect the LO LO alarm condition.
LO_LO_PRI 31 None The priority of the LO LO alarm.
