6.4.5 Process Alarm High Setpoint (Words 4, 10, 16, 22)

The user defines the process alarm high value using this signed word element. The range
of this value is dictated by the selected data format. When the measured analog signal for
the associated channel exceeds the high process alarm, an alarm bit will be set in the
input data table that corresponds to the associated channel. See Input Type and Data
Format (Words 3, 9, 15, 21) for more information regarding data format.

6.4.6 Process Alarm Low Setpoint (Words 5, 11, 17, 23)

The user defines the process alarm low value using this signed word element. The range
of this value is dictated by the selected data format. When the measured analog signal for
the associated channel drops below the low process alarm, an alarm bit will be set in the
input data table that corresponds to the associated channel. See Input Type and Data
Format (Words 3, 9, 15, 21) for more information regarding data format.

6.4.7 Process Alarm Deadband (Words 6, 12, 18, 24)

The deadband is a range through which the measured input may be varied without
initiating an alarm response. The deadband will use the data format selected in the
channel configuration. See Input Type and Data Format (Words 3, 9, 15, 21) for more
information regarding input type and format. The deadband is added to the low alarm
value and subtracted from the high alarm value. In both cases, the resulting value must
