Standard FF alarm behavior. The time when the parame-
ter was updated.
Standard FF alarm behavior.
Standard FF alarm behavior. The relative OD index of the
static parameter whose change caused this alert.
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 sub code field. The first
alert to become active sets the Active status in the Status
attribute. 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 sub code
has changed.
Unacknowledged has the following enumerations:
0 = Undefined.
1 = Acknowledged.
2 = Unacknowledged.
Alarm State has the following enumerations:
0 = Undefined.
1 = Clear - reported.
2 = Clear - not reported.
3 = Active - reported.
4 = Active - not reported.
Alarm time.
For Block Alarms, when multi-bit alarms are selected
using the resource block FEATURES_SEL parameter, the
sub code contains the two byte bitstring value of Block
Error when taken as an Unsigned16, such that the most
significant bit (MSB) of the Block Error bitstring is mapped
to the most significant bit (MSB) of the Unsigned16 that
represents the subcode attribute of the Alarm parameter.
For all other alarms, the subcode contains an enumera-
tion specifying the cause of the alert to be reported. It is
used primarily for diagnostic alarms, notified with block
alarm. Standard sub codes are defined by the Fieldbus
Foundation, although manufacturers may define addi-
tional ones.
