Startup Command File

Number of connection attempts to source server

This parameter is used to specify the number of times to try connecting to source server if
connection fails the first time. It can be used to restrict failover from occurring until after a
certain number of attempts made to connect to the primary server have failed. The default
number of attempts is 1.(

/NT=x)

Enable failover status logging.

This check box is used to enable failover status logging. By checking this box, the user is
allowed to enter a Receiving Server Status Tag. This

tagname

entered in this text box is the

failover status tag configured on receiving server. Click the Browse button to invoke the Tag
Search utility to browse for this tag. (

/FST=tagname

)

Note: The UniInt Interface User Manual includes details about other command-line
parameters, which may be useful.

Configuring Interface Startup Files

The interface has two startup configuration files;

PItoPI.bat

and

PItoPI.ini

. The

.bat

file is required and is the primary file for specifying interface configurations. The

.ini

file

should only be used if configuring one copy of the interface to collect data from multiple
source Historian Servers. In this configuration each scan class can be configured for a unique
source Historian Server. This is not recommended for exception data collection. Interface
performance is maximized by running a separate copy of the interface for each source
Historian Server.

When using the

.ini

file, global parameters such as point source are defined in the

.bat

file. Scan class specific parameters are defined in the

.ini

file, such as source Historian

Server. When a parameter is set in both the

.bat

and

.ini

file, the

.ini

file takes

precedence.

When configuring the

.bat

startup file the continuation character ^ can be used to allow

multiple lines for defining parameters. The maximum length for a single line is 1024
characters (1 kilobyte). The number of parameters is unlimited, and the maximum length of
each parameter is 1024 characters.

Command-line Parameters

These parameters are displayed in five groups: General Interface Operation, History
Recovery and Archive Data Collection, Exception Data Collection, Tag Attribute Override,
and Server-level Failover.
