Network configuration

 Network topology
The network can be wired into star topology, line topology, and ring topology. A network can consist of a combination of star
and line topologies.
Item
Units are configured into a star using a switching hub and Ethernet cables. Except for the master, units can be easily
*1
Star topology
added in a star topology. Furthermore, data link continues among normally-operating stations in a star topology.
Line topology Units are configured into a line using Ethernet cables. A switching hub is not required.
*2
Units are configured into a ring using Ethernet cables. Data link continues with the stations that are operating normally.
Ring topology
*1 A general-purpose switching hub cannot be used for EtherCAT communication. Use an EtherCAT branch slave.
*2 Ring topology is available only for EtherCAT communication. Use an EtherCAT branch slave.
 Station number and connection position
Units can be connected in any order regardless of the station number.
 Replacing CC-Link IE TSN devices
For star topology, units (except for the master) can be replaced without powering off the whole system.
NOTE
• Refer to the Master Module User's Manual for detailed network configurations.
