UniInt Interface User Manual 9

Parameter

Description

/host=host:port

Optional

Default = default

Historian Server from

the pilogin.ini file.

The /host parameter is used to specify the Historian Home

node. host is the IP address of the Historian Sever node or

the domain name of the Historian Server node. port is the

port number for TCP/IP communication. It is recommended to

explicitly define the host and port on the command-line with

the /host parameter. Nevertheless, if either the host or port

is not specified, the interface will attempt to use defaults.

Defaults:

The default port name and server name is specified in the

pilogin.ini or piclient.ini file. The piclient.ini file

is ignored if a pilogin.ini file is found. Refer to the PI

API Installation Instructions manual for more information on

the piclient.ini and pilogin.ini files.

If the interface is configured to use the PI SDK, localhost

should not be used, rather the name of the IF node computer

should be used.

Examples:

The interface is running on a Historian Interface node, the

domain name of the Historian 3 home node is Marvin, and the

IP address of Marvin is 206.79.198.30. Valid /host

parameters would be:

/host=marvin

/host=marvin:5450

/host=206.79.198.30

/host=206.79.198.30:5450

/id=x

Optional

Default = none

The /id parameter is used to specify the interface identifier.

For example,

/id=int1

The interface identifier is a string that is no longer than 9

characters in length. UniInt concatenates this string to the

header that is used to identify error messages as belonging to

a particular interface. See the section called “Error and

Informational Messages” for more information, page 99.

UniInt always uses the /id parameter in the fashion

described above. Many interfaces also use the /id parameter

to identify a particular interface copy number that corresponds

to an integer value that is assigned to one of the Location

code point attributes, most frequently Location1. For these

interfaces, one should use only numeric characters in the

identifier. For example,

/id=1

When an interface uses the /id parameter to specify an

interface copy number, the point source character should be

the same for all copies of the interface. For example, all

Historian Points for the Modbus interface are typically

configured with a point source of M. Modbus points are

distinguished as belonging to a particular copy of the Modbus

interface by assigning a copy number to the Location1

attribute of the point, which, in turn, corresponds to the copy

number designated by the /id parameter.

If the interface does not have a parameter such as the /id

parameter to identify a particular copy of the interface, a

different point source must be used for each copy of the

interface. Interfaces sometimes use other parameters besides

1 2 ... 10 11 12 13 14 15 16 17 18 19 20 ... 107 108
