Controller user home

The user homes are the locations under which all configurable data reside. Included are stations, templates, registry, logs, and other data. Referred to by the alias niagara_user_home, the separation of these files from the runtime files stored in the system home folder is new in Niagara 4.

The JACE controller has one system home and one user home.

Callout 1 above identifies a controller’s system home (alias: niagara_home) in both the Nav tree and the Platform Administration view. In the Nav tree, you can find the controller’s system home by expanding Platform > Remote File System. The actual folder for the system home is /home/niagara.

Callout 2 identifies the controller’s user home or daemon user home (alias: niagara_user_home) that contains the installed and running station and other configuration files. The actual folder for the daemon user home is: /home/niagara.
