Configuring UniInt Failover through a Shared File (Phase 2)
Start-Up Parameters
Note: The /stopstat parameter is disabled If the interface is running in a UniInt
failover configuration. Therefore, the digital state, digstate, will not be written to
each Historian Point when the interface is stopped. This prevents the digital state
being written to Historian Points while a redundant system is also writing data to the
same Historian Points. The
/stopstat parameter is disabled even if there is only
one interface active in the failover configuration.
The following table lists the start-up parameters used by UniInt Failover Phase 2. All of the
parameters are required except the
/UFO_Interval startup parameter. See the table below
for further explanation.
Parameter
Required/

Description Value/Default
/UFO_ID=# Required Failover ID for IF-Node1
This value must be different from
the failover ID of IF-Node2. Any positive, non-
zero integer / 1
Required Failover ID for IF-Node2
This value must be different from
the failover ID of IF-Node1. Any positive, non-
zero integer / 2
/UFO_OtherID=# Required Other Failover ID for IF-Node1
The value must be equal to the
Failover ID configured for the
interface on IF-Node2. Same value as

Required Other Failover ID for IF-Node2
The value must be equal to the

synchronization The Failover File Synchronization
Filepath and Optional Filename
specify the path to the shared file
used for failover synchronization
and an optional filename used to
specify a user defined filename in
lieu of the default filename.
The path to the shared file
directory can be a fully qualified
machine name and directory, a
mapped drive letter, or a local path
if the shared file is on one of the
interface nodes. The path must be
terminated by a slash (
/ ) or
backslash ( \ ) character. If no
terminating slash is found, in the
/UFO_Sync parameter, the
interface interprets the final
character string as an optional
filename.
The optional filename can be any
valid filename. If the file does not
