10 – Configuring Security and Access
222 R400
Using Areas to Control Access to the System
When you assign areas, you control the level of access to an area by setting the
security level. Area security levels are used in conjunction with the existing
operator-based or Station-based security.
For example, if an area is defined with an area code of A1, all point IDs with an
area code of A1 would only be viewable by Stations or operators that have area
A1 assigned to them with an access level of at least View.
Note • Alarms in an area can be temporarily disabled using the Status Change
Alarm Area Inhibit algorithm. See “Configuring Algorithms” on page 193 for
details.
• If areas are assigned to points or processes that are currently in alarm, these
existing alarms will not observe area restrictions. It is therefore
recommended that areas be configured before points are defined or else
when there are no alarms affecting points and processes in the areas you
are creating.
• Area number 1 is reserved for system item alarms and alarms for points that
have not been assigned to an area.

and select the level of access for each area.
Tip To assign or change areas for different Stations, use the drop-down list of Stations
available above the Area Assignment tab.
