dataAlarmString This text string object contains the last data
record which was received which matched the data
alarm equation associated with this data alarm.
Since data records may be received after a data
alarm initiates its actions, retrieval of this
object after a data alarm is activated may not
result in the retrieval of the data record which
activated the data alarm. However, this object
will contain the last data record which was
received which did match the alarm equation
associated with this data alarm.
dataAlarmPort This integer object contains the serial I/O port
number upon which the text string contained in the
dataAlarmString was received.
sensorAlarmTable This table contains the configuration objects for
the sensor alarms. This table always has as many
entries as there are sensors available to
configure in the SNMP Access Gateway.
sensorAlarmActive When this object is set to a value of 0, the
associated sensor is not enabled for activating
alarms. When this object is set to a value of 1,
the associated sensor is enabled for activating
alarms.
sensorAlarmName This text string object holds a name associated
with this sensor alarm.
sensorType When this integer object is set to a value of 0,
the sensor is processed as a contact closure
sensor, with states of Opened and Closed. The
sensor is normally opened, and is treated as
closed when the sensor contact is connected to
ground. When this object is set to a value of 1,
the sensor is processed as an analog voltage
sensor. In this case the sensor takes on values
from 0-255, when the analog input voltage goes
from 0 to 5 volts.
sensorAlarmMode This integer object controls the mode of
activation of the sensor. When the sensorType is
0 (a contact closure sensor) then the
sensorAlarmMode may be set by the user to values
of 0 (active when contact is opened) or 1 (active
when contact is closed). When the sensorType is 1
(analog sensor) then the sensorAlarmMode may be
set by the user to values of 0 (active when
voltage drops below normal range minimum), 1
(active when voltage goes above normal range
maximum) and 2 (active when voltage goes outside
of normal range). The current sensor state is then
reflected in sensorAlarmState.
sensorRangeMin This integer is the minimum A/D value for the
‘normal’ operating range for the sensor attached
to an analog input. For an analog sensor alarm
which is triggered by dropping below the minimum
A/D value the sensorRangeMin object sets the A/D
value under which the voltage must drop.
sensorRangeMax This integer is the maximum A/D value for the
‘normal’ operating range for the sensor attached
to an analog input. For an analog sensor alarm
which is triggered by exceeding the maximum A/D
value the sensorRangeMiax object sets the A/D
value which the voltage must exceed.
sensorAlarmState The sensorAlarmState object is a read-only object
which holds the curent state of the sensor (opened
or closed when in contact closure mode, or the
current A/D value being read if in analog mode).
