SynchLink Fiber Optic Cable System
The SynchLink fiber optic cable system is designed to be
user-constructed and installed. To take full advantage of this flexibility,
you should spend sufficient time planning your system's installation
before assembling any of the hardware.
The time and effort spent on planning your cable system installation
will be insignificant compared to the time and effort required to locate
and repair damaged or improperly installed hubs, cables, and/or other
cable system components. For more information, see Chapter 6,
Planning a SynchLink Fiber Optic Cable System.
Since SynchLink lacks many features of a typical
IMPORTANT
network, we recommend that you use it in
conjunction with a ControlNet, EtherNet I/P, or
DeviceNet network for monitoring SynchLink node
status and other appropriate functions.
Determine Your Topology
The first step is to analyze your application and determine the
topology of your SynchLink system. SynchLink system topologies are
described in Chapter 2. Specific configurations that may be used in
each topology are described in Chapter 4.
