Figure 1-6. Library Location Coordinates
The module digit uses a zero-based numbering system. The control module is
labeled as 0 (zero). The front, left-most column in the module is labeled 1. The top
slot in each column is labeled 1. For more information, refer to the sections that
follow.

Modules

Library modules are represented by the first digit of a library coordinate. Modules
are identified relative to the control module (CM). The CM is number 0. The
module stacked below the CM is numbered with a negative integer digit, also
depending on its relative position to the CM. The expansion module directly below
the CM is number -1.

Columns

A storage column is a group of slots arranged vertically in the library. Columns are
represented by the second digit of a library coordinate. Columns are identified
relative to the front left of the library. The column in the front left of the library is
number 1. The column numbering continues around the library in a clockwise
direction. The I/O Station column is always number 6.
