Figure 2-9. 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. Modules
stacked above the CM are addressed with positive integer digits depending on
their position above the CM. For example, the expansion module stacked directly
above the CM is number 1. The expansion module stacked directly above module
1 is number 2, and so on.The module(s) stacked below the CM is numbered with a
negative integer depending on its relative position to the CM. The expansion
module directly below the CM is number -1. If there is an expansion module
installed above the CM, it will be numbered +1.The expansion module stacked
directly below module -1 is number -2, and so on.

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
