Interface Startup Parameters
10
Parameter Description
the /id parameter (such as /in , /ic , etc) to identify the
copy of an interface. Consult the interface-specific
documentation for more information.
/IOSourceTime
Optional
The /IOSourceTime stands for Initial output source
timestamp. Some interfaces send the current value of the
source tag at start-up. If this parameter is not specified, the
timestamp sent with the initial value is the current Historian
Time. This command-line parameter instructs UniInt to send
the timestamp of the source tag‟s snapshot value to the
interface specific code that handles the actual output.
/logps
Optional
When the /logps parameter is present, the point source for
the interface will be included in the header of the log
messages sent to the pipc.log file.
/logUFOID
Optional
When the /logUFOID parameter is present and the
interface is configured for UniInt failover, the failover ID for the
interface will be included in the header of the log messages
sent to the pipc.log file.
/maxstoptime=
stoptime
Optional
Default = 120 seconds
When an interface receives a signal from the operating
system to shut down, there is a list of clean up functions that
need to be performed. If for some reason the execution of
these functions takes longer than the
stoptime , the
interface will shut down without finishing its tasks.
/NoOutputs
Optional
If this parameter is specified, outputs are disabled.
If outputs are disabled, the message
/NoOutputs flag detected. Outputs from
Historian disabled
will be written to the message log when the interface starts.
/perf=interval
Optional
Default = 8 hours
When the percentage of scans that a UniInt-based interface
performs on time drops below 95%, UniInt will print out
performance summaries for each scan class. Performance
summaries are described in the section called “Performance
Summaries
.”
UniInt checks whether a performance summary is in order
every
interval hours. For example, if /perf=0.025 ,
UniInt will write performance summaries every 90 seconds if
the percentage of on-time scans is below 95%. The minimum
time between summaries is 60 seconds. Setting
/perf=0
disables summaries. If the /perf parameter is omitted, then
UniInt checks whether summaries are in order every 8 hours
by default.
If the inputs for the interface are unsolicited, then performance
summaries should be disabled by setting
/perf=0 because
performance summaries are meaningless for unsolicited input
points.
