Interface Startup Parameters

Parameter

Description

/SVCEventsTO=#

Optional

Default = 500 msec

The /SvcEventsTO=x controls the Service Events

TimeOut. The x is the timeout period specified in milliseconds.

Events are serviced (retrieved from the evmexceptions queue

on the Historian Server) for 500 milliseconds or until there are

no more events in the queue. After either of those events,

UniInt will perform the other tasks it is responsible for such as

scanning for input data and checking for Historian point

database changes. If the interface is servicing a lot of events,

the time may not be sufficient and can be adjusted with the

SvcEventsTO=x command-line parameter. The minimum

value for x is 0. If the Service Events TimeOut parameter is

set to 0, UniInt will service 36 events at a time and then

continue to perform its other tasks. The maximum value for x

is 3000 (3 seconds).

/sio

Optional

Default = send initial outputs

The /sio parameter stands for “suppress initial outputs.” The

parameter applies only to interfaces that support outputs. If

the /sio parameter is not specified, the interface will behave

in the following manner.

When the interface is started, the interface determines the

current Snapshot value of each output tag. Next, the interface

writes this value to each output tag. In addition, whenever an

individual output tag is edited while the interface is running,

the interface will write the current Snapshot value to the edited

output tag.

This behavior is suppressed if the /sio parameter is

specified on the command-line. That is, outputs will not be

written when the interface starts or when an output tag is

edited. In other words, when the /sio parameter is

specified, outputs will only be written when they are explicitly

triggered.

/sn

Optional

Default = send exceptions

When this parameter is specified on the command-line, all

exception reporting is disabled. Unless the interface-specific

documentation says otherwise, this parameter should not be

used during normal interface operation.

/startup_delay

/startup_delay=delay

Optional

Default = no delay

Default if parameter is

specified with no value = 30

seconds

After UniInt prints out the “Starting Interface.” startup

message, UniInt will wait delay seconds before proceeding.

If the /startup_delay parameter is specified without

specifying a delay time, then the default delay is 30 seconds.
