Figure 81 - Node Addressing Example 2
In this example, Sercos interface module 1 controls axes
1…4 and module 2 controls axes 5…7. The slot-filler module is not assigned a
Sercos node address, but the system identifies it with a slot location.
You can mount the two Sercos interface modules in two separate ControlLogix
chassis (as shown) or you can mount them in the same chassis.

IMPORTANT The node address for each axis module is determined by the base node-
address switch setting on the IAM module.
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.
IMPORTANT Slot-filler modules must be used to fill any unoccupied slot on the power
rail. However, you can replace slot-filler modules with AM modules or the
2094-BSP2 shunt module (maximum one 2094-BSP2 shunt module per
power rail).
