THE ALARMS TAB
The four “soft” process alarms may be used to monitor process status, and may be used to
actuate the module’s physical outputs. Otherwise, the bit alone may be monitored via the
system itself, or via external devices.
• The Mode property determines what behavior the alarm will assume. The table
below describes the various selections.
MODE
Absolute Low

DESCRIPTION
The alarm activates when the measured value falls below
the Alarm Value. The alarm deactivates when the
measured value goes above the Alarm Value + Hysteresis.
The alarm activates when the measured value exceeds the
Alarm Value. The alarm deactivates when the measured
value falls below the Alarm Value – Hysteresis.
If the measured value falls below the Setpoint Value by
the amount of the Alarm Value, the alarm activates. In
this mode, the alarm point tracks the Setpoint Value.
If the measured value exceeds the Setpoint Value by the
amount of the Alarm Value, the alarm activates. In this
mode, the alarm point tracks the Setpoint Value.
If the difference between the Setpoint Value and the
measured value is not greater than the Alarm Value, the
alarm activates.
If the measured value exceeds, or falls below, the Setpoint
Value by an amount equal to the Alarm Value, the alarm
activates. In this mode, the alarm point tracks the Setpoint
Value.
• The Assignment property changes the value that the alarms will monitor, and
therefore react to.
