Stations
Operators generally need dedicated Stations, whereas maintenance engineers may only need
access to a Station for a few minutes, two or three times a day. Other users, such as managers
and production controllers, may only need read-only access to trend-related displays and
reports.
Connection options for Flex Stations
There are two ways of connecting a Flex Station to the server:
Static. A permanent, dedicated connection. This is the recommended connection type
n
for Flex Stations used by operators.
Rotary. An 'as required' connection. This is the recommended connection type for
n
users who do not need full-time access to the server, or who need remote access
(typically through a modem).
Rotary connections are advantageous from a licensing viewpoint because the license
specifies the maximum number of simultaneous Station connections.
About Console Stations
Console Stations provide direct access to process data as well as alarms and messages from
CDA sources such as Process Controllers. This direct access provides a continuous view of
your process, even if the Experion server is unavailable (for example, during a server
failover). Consequently, there is no loss of view of critical data and alarms when the server
fails, and so an operator can still control and monitor the process.
During server outages, any specific chart visualization access directly to the Engineering
Repository Database (ERDB) view is not available unless at least one of the servers is
available. Other views, such as Detail Displays, remain available at all times.
A Console Station is also connected to an Experion server. After you configure the
connection to the Experion server, the server database files are replicated to the Console
Station. This means that configuration of items such as process points is only done once.
Although a Console Station provides direct access to data, alarms and messages, some
functions, such as reporting, history and events collection, are still provided by the Experion
server. Therefore, if the Experion server is unavailable these functions are not available on the
Console Station. For details, see the "Functions available on the Console Station" and "What
happens when the Experion server is unavailable" topics in the "Configuring Console
Stations" section of the Station Configuration Guide.
