Interface Startup Parameters

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.
