3. Network Topologies
Topology refers to the shape of a network, or the network's layout. How different nodes in a
network are connected to each other and how they communicate, is determined by the network's
topology. The CL4490s support a Point-to-Point and a Point-to-Multipoint network topology.
3.1 Point-to-Point
A point-to-point system is a simple arrangement consisting of just two CL4490s - a Server and a
Client. Sometimes referred to as a wireless bridge, a point-to-point link replaces a single
communications cable. A point-to-point link might be used to connect a PLC to a remote
monitoring station.
3.2 Point-to-Multipoint
Point-to-Multipoint systems have one base station, or access point, that controls communications
with all of the other wireless nodes in the network. This allows for the creation of a wireless
network consisting of multiple nodes. By programming each CL4490 with a network specific
Channel Number and System ID multiple networks can be created see (Fig 9).
