Startup Command File
64
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.
