Node Addressing Example 3
In Example 2, the Kinetix 6000 (8-axis) power rail contains a
double-wide IAM, two double-wide AMs, one single-wide AM, and
one slot filler module. The slot filler module is assigned a node
address, but does not use it.
The leftmost slot of a double-wide module determines the node
address. So, in the example above, node addresses 02, 04, and 06 (the
rightmost slots of the double-wide modules) are not used.

IMPORTANT
Slot filler modules must be used to fill any unoccupied slot on
the power rail. However, the slot fillers may also be removed
and replaced by an axis or shunt module in the future.
IMPORTANT
Do not position axis modules to the right of shunt or slot filler
modules. The added distance between non-adjacent axes can
increase electrical noise and impedance, and requires longer
fiber-optic cable lengths.
