following:

RSView32 commands, or see Help.
Alarm events
You can customize and extend the RSView32 alarm monitoring
system by writing your own alarm detection algorithms using PLC
ladder logic, VBA programs, or any other appropriate tools. You can
then add alarm events to the RSView32 alarm subsystem, to respond
to your alarm detection algorithms for annunciation, logging, printing,
and for display in alarm summaries.
By using a tag name for an alarm event, you can customize the alarm
features of the tag. For example, you can use alarm events to specify
an alarm’s time stamp. Because alarms are scanned in the background,
alarms that are generated rapidly may appear out of sequence in
RSView32, because they may all be scanned at the same time, and
therefore given the same time stamp. If the sequence in which alarms
are generated is important, you may want to record accurate time
stamps for the alarms by buffering the alarms in the PLC, and then
using alarm events to record them with accurate time stamps in
RSView32.
You can also use alarm events to provide a tag with more than 8
thresholds.
To create an alarm event, use the AlarmEvent command.
