Integrated Motion on the EtherNet/IP Network Applications for PowerFlex 755 AC Drives Chapter 6
Network Topologies This topic provides examples of network topologies that can be used when
implementing an Integrated Motion on EtherNet/IP Network application by
using on of the following programming software applications.
• RSLogix 5000, version 19 and later
• Studio 5000 environment, version 21 and later
Star Topology
A switch-level star configuration is a traditional Ethernet network layout where
devices are connected to a centralized network switch, point-to-point. The star
configuration is most effective when the devices are near a central network
switch. In a star network topology, all traffic that traverses the network (that is,
device-to-device) must pass through the central switch.
It is recommended that a managed switch with a transparent and/or boundary
clock, plus QoS and IGMP protocol support be used for this Network topology.
Although the ControlLogix is illustrated, the CompactLogix controller could
also be used.
Advantages/Disadvantages
The advantage of a star network is that if a point-to-point connection is lost to an
end device, the rest of the network remains operational.
