Best practice planning alarm system
► Determine Alarms before hand► Use IO/Lists► Communicate with the process department► Do not alarm on every single I/O only the absolute
necessary ones► Prioritize your alarms (Critical to Info)► Build the critical alarms into your templates to
enforce standards through to all the instances► Plan the areas before hand and build your model
accordingly► How will you visualize the alarms?
Where do we store the alarms

Historical Alarms
► Benefit of using multiples alarm providers
No historical data loss
Minimize Network Traffic
No single point of failure
Historical Alarms and redundancy
► Alarms in redundant configuration :
Described in Implementing Redundancy section of the deployment guide
Also refer to Technote 430

New Alarm Controls
► Alarms are viewed in the new Alarm Client Controls.
► The new alarm client can be found in the graphic toolbox
New Alarm Controls
► The Client Control can be embedded and configured in the graphic symbol editor

with the critical alarm
