Commissioning Your 1394 SERCOS Interface System 1-9
Refer to Figure 1.5 for an example of the fiber-optic ring connections
between the 1394 system module(s) and the SoftLogix PCI card.
Although Figure 1.5 only illustrates the SERCOS fiber-optic ring with
the SoftLogix PCI card, node addressing for SoftLogix is done the
same way as shown in the ControlLogix example.
Figure 1.5
Fiber-Optic Ring Connection (SoftLogix)
Axis 0 of each system module has a node address of the switch setting
times 10 (for example: system number 1 times 10 = 10 and axes 1-3 on
this system are numbered 11, 12, and 13, respectively). Refer to Figure
1.6 for an example of how node addresses are assigned.
