When you install Data Archive, the setup program prompts you for a location to store the files. By default, Data Archive installs its files in a folder called PI on the disk with the most available space. The PISERVER environment variable points to this directory.
The PI directory includes the following subdirectories:
|
Subdirectory |
Contents |
|---|---|
|
Program Files\PI\adm |
Administrative tools. |
|
Program Files\PI\bin |
Subsystem or PI service executables. |
|
Program Files\PI\dat |
Databases and tables such as Point Database and Digital State Table. This is also the default directory for archive files and the event queue. |
|
Program Files\PI\interfaces |
Interfaces that were installed with previous versions of Data Archive. This directory is not present on new Data Archive installations. |
|
Program Files\PI\log |
Log files. |
|
Program Files\PI\setup |
Files for install and uninstall. |
In addition to the PI directory, the Data Archive installation creates the pipc directory during the PI SDK installation. The pipc directory contains files for the PI SDK and other tools and utilities, including PI SMT, Collective Manager, and PI ICU. The PIHOME environment variable points to this directory.
