RTU/Controller
Network Topology
Connecting the EtherTRAK-2 I/O modules to the SixTRAK IPm RTU/Controller is typically done with one or combination
of one or more network topologies. These topologies are ring, passthru and star. They are defined below.
Ring Topology
Connect a ring of I/O modules to the SixTRAK IPm RTU/Controller using a Red Lion Sixnet Monitored and Managed
Series switches. The Ring network creates a reliable redundant ring capable of recovering very quickly. Multiple Rings may
be connected to the SixTRAK IPm RTU/Controller through switches and can be connected to either Network 1 or Network
2. The EtherTRAK-2 I/O modules must be in Ring mode to use this network configuration.
Figure 3.4. Ring Topology
Passthru Topology
In this configuration no additional switches are needed. Simply daisy chain the EtherTRAK-2 I/O modules together and
connect the first in the chain to the SixTRAK IPm RTU/Controller. Multiple chains may be connected to either Network 1
or Network 2. The EtherTRAK-2 I/O modules must be in PASSthru mode to use this network configuration.
