Description
The identification number
of the plant unit. This infor-
mation may be used in the
host for sorting alarms, etc.
The block alarm is used for
all configuration, hardware,
connection failure, or sys-
tem problems in the block.
The cause of the alert is en-
tered in the Subcode field.
The first alert to become ac-
tive will set the Active sta-
tus in the Status parameter.
As soon as the Unrepor-
ted status is cleared by the
alert reporting task, another
block alert may be reported
without clearing the Ac-
tive status if the subcode
has changed.
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.
