Understanding the Location Coordinates
This section describes the numbering system used to identify components of the library. The library location
coordinates contain the following digits: [Module],[Column],[Slot].
Figure 10 shows how a library with a
control module and an expansion module is numbered.
Figure 10 Library Location Coordinates
Modules
Library modules are represented by the first digit of a library coordinate. Modules are identified relative to
the control module.
The control module is numbered 0 (zero). Expansion modules stacked above the control module are
addressed with positive integer digits depending on their position above the control module. For example,
the expansion module stacked directly above the control module is number 1. The expansion module
stacked directly above module 1 is number 2, and so on.
Modules stacked below the control module are numbered with negative integer digits, also depending on
their relative position to the control module. For example, the expansion module stacked directly below the
control module is number -1. The expansion module stacked directly below module -1 is number -2, and so
on.
