Information on diagnostics structure and plant hierarchy

Diagnostics structure in the plant hierarchy
The diagnostics structure is a folder structure in the plant hierarchy and is automatically created
by the system. The number of hierarchy levels is limited to 8.
The diagnostics hierarchy folder is the top hierarchy folder; it maps the area-forming level for
the OS (area selection button in overview of process control). Depending on the set level OS
area in the plant hierarchy, a maximum of three folders is created with the name "Diagnostics".
The hierarchy folders with the names AS objects, field devices, network objects, and PC
stations are created on the same hierarchy level below the diagnostics hierarchy folder that
maps the OS area. The version of the maintenance station and the existing objects determine
which hierarchy folders are created.
The names of the automatically generated hierarchy folders cannot be changed.
