Parameter

Description

/PISDK=#

Optional

Default = 0

The /pisdk parameter can be used to enable or disable the

PI SDK in some situations. Use /pisdk=1 to enable the PI

SDK. Use /pisdk=0 to disable the PI SDK. If a particular

interface requires the PI SDK, then the PI SDK will always be

enabled and the /pisdk parameter will be ignored.

If the interface is running on an interface node with the PI API

version 1.6.x or greater and the version of the Historian Server

is 2.x or greater, the interface will ignore the /pisdk

parameter and the SDK will not be used to retrieve point

attributes.

/pisdkcontimeout=

contimeout

Optional

Default = connection timeout

set with the Connection

Manager

contimeout is the timeout in seconds used for opening

the initial connection to the Historian Server. All other PI SDK

calls use the timeout defined by the /pisdktimeout

parameter.

The timeout set with this parameter overrides the connection

timeout listed in the connection settings dialog that can be

viewed from the Connection Manager. The Connection

Manager should be used for adjusting the SDK connection

timeout. This parameter should only be specified if the

interface uses the PI SDK and a connection timeout that is

different than the connection timeout set with the Connection

Manager is required.

/pisdktimeout=

timeout

Optional

Default = data access timeout

set with the Connection

Manager

timeout is the timeout in seconds used by PI SDK calls.

The timeout set with this parameter overrides the data access

timeout listed in the connection settings dialog that can be

viewed from the Connection Manager. The Connection

Manager should be used for adjusting the SDK data access

timeout. This parameter should only be specified if the

interface uses the PI SDK and a data access timeout that is

different than the one set with the Connection Manager is

required.

/ps=source

Required

The /ps parameter specifies the point source for the

interface. Source is not case sensitive. The length of

source is limitied to 100 characters by UniInt. Source can

contain any character except „*‟ and „?‟.

The point source that is assigned with the /ps parameter

corresponds to the PointSource attribute of individual

Historian Points. The interface will attempt to load only those

Historian Points with the appropriate point source.

If the PI API version being used is prior to 1.6.x OR the

Historian Server version is prior to 2.x, source is limited to a

single character unless the SDK is being used. See the /pisdk

parameter for more information.

Strategies for assigning a point source character vary

depending on the interpretation of the /id parameter by a

particular interface. See the /id parameter for more

information.

Optional

Default = no queuing

When the /q parameter is present, Snapshots and

exceptions are queued before they are sent to the Historian

Server node. The maximum queue size is close to 4000 bytes.

The queue is flushed between scans if it is not filled. For

interface collecting unsolicited data, the queue is flushed four

times a second if it is not filled.
