Connecting Your SERCOS
Fiber-Optic Cables
This procedure assumes you have your ControlLogix chassis with
1756-MxxSE interface module or personal computer with
1784-PM16SE PCI card and Ultra3000 SERCOS interface system(s)
mounted and are ready to connect the fiber-optic cables.
The SERCOS fiber-optic ring is connected using the SERCOS Receive
and Transmit connectors. Refer to Chapter 2 for the location of the
connectors on your Ultra3000-SE drive(s) and Figure 3.20 to locate the
connectors on your SERCOS interface module or PCI card.
Note: Plastic cable is available in lengths up to 32 m (105.0 ft). Glass
cable is available in lengths up to 200 m (656.7 ft).
