Figure 78 - Node Addressing Example 3
In this example, the Kinetix 6000 (8-axis) power rail contains a double-wide
IAM module, two double-wide AM modules, one single-wide AM module, and
one slot-filler module. The slot-filler module is not assigned a SERCOS node
address, but the system identifies it with a slot location.
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-filler modules may also be removed and replaced
by an AM 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.
