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.
/q
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.
