Node Addressing Examples
The examples below illustrate how each axis in the fiber-optic ring is assigned a
node address. The ControlLogix platform is used in the examples, but the node
addressing is typical for Logix platforms.
Figure 65 - Node Addressing Example 1
In this example, SERCOS interface module 1 controls Kinetix 7000 axes 1 and 2.
SERCOS interface module 2 controls Kinetix 7000 axis 3.

TIP
You can mount the two SERCOS interface modules in two separate Logix
chassis (as shown above) or you can mount them in the same chassis.
Utilizing two SERCOS interface modules to control axes from a single Kinetix
7000 drive lets you reduce cycle times.
