Support
Operating in the OS/2 environment, AMU software consists
of five proprietary operational processes and two proprietary
utility processes. The task of each of the seven processes are
listed below:
• Communication with host computer, robot control,
Quadro Tower control, and Hexa Tower control
• Management of the library catalog using Source Query
Language (SQL) database
• Kernel logic converts host commands into control
commands
• User interface for operator requests
• Log and trace connection
• Database backup facility
• Remote file transfer
In normal (Automatic) operating mode, the host computer
directs the AML/J and the AMU software operates
transparently. Usually, commands are only input at the AMU
console through the Graphical User Interface (GUI) for direct
operator intervention.
