A note about the Alarm 1 and Alarm 2 values reported in Excel:
The alarm value is the decimal equivalent of a 30-bit binary number
represents the alarm conditions for each of the 30 instrument channels (20
analog and 10 computed channels).
In the simplest case, all 30 channel alarms are off and alarm value is 0. In the
most complex case, all 30 channel alarms are on and the alarm value is
1073741823. See the following chart for Alarm Value examples.
