AMU Basic Functions
During normal operation in the “AUTO” mode, the host
computer controls the system.
The AMU´s basic tasks are:
• host communication - interprets the incoming host
commands and checks these commands for executability
• management of the archive catalog - saves the logical
coordinates of the compartments, assigns the media to
compartments and traces the status of compartments and
drives
• conversion of logical coordinates into physical
coordinates
• communication with the control units of the robots and
storage towers
• provides operator interface for installation and service
• configuration (describes the specific structure of the
system)
The AMU does not have access to the data content of the
media.
