System Status Network tree
which forms them into an FTE Community.
System Performance Server (SPS) should be installed on all Experion servers.

The System Event Server is installed on one of the redundant server pairs in each
n
workgroup or domain.
The System Event Server scope of 'domain' (its default setting) is appropriate for these
n
topologies.
When there are multiple Experion servers in an FTE Community, the Distributed
n
System Architecture (DSA) option should be enabled so that the servers can share SES
event data.
Each server in the FTE Community subscribes to the server hosting the SES in each
n
workgroup or domain.
If Server1 and Server2 are DSA connected, duplicate FTE event notifications occur.
n
To eliminate these duplicate FTE event notifications, remove the FTE event filter file
(FTEFilter.xml) from all but one SES pair.
The FTE event filter file is located at C:\HWIAC\Filters\FTEFilter.xml<data
folder>\Honeywell\ProductConfig\Filters\FTEFilter.xml.
Where <data folder> is the location where Experion data is stored. For default
installations, <data folder> is C:\ProgramData. The C:\ProgramData folder
is a system folder, which means that it is only visible if you select the Show hidden
files, folders, and drives option button in the Folder Options dialog box. To change
this setting in Windows Explorer, click Organize > Folder and search options, and
then click the View tab.
SES event notification behavior
Events are gathered by the System Event Provider (SEP), part of system management
runtime. The events are synchronized on all nodes within the FTE Community and domain.
The SES is used to convert these events to an OPC event usable by the Experion server.
If the SES fails, an event is generated by the Experion server indicating that it has lost the
connection to the SES. System Events are not viewable until the SES is restarted, or the
Experion server fails over to the redundant server. When SES is restarted, it reads all events
from the SEP and makes them available to the server. No event loss occurs. If the SEP fails,
the SES reports loss of connection with its data source (SEP), and no system events are
available. When the SEP is restarted, it synchronizes with another node which has the full set
of events. In addition, new events that occurred during the time that SEP was unavailable are
read and added to the event list. No event loss occurs.
Network tree planning summary
Honeywell recommends that one of the above topologies be chosen when implementing
Experion. Utilizing these topologies will allow for simplified configuration and cater to future
