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, but the ring topology cannot be combined with star or line topology.
Item
Modules are configured into a star using a switching hub and Ethernet cables. Slave stations can be easily added in a
Star topology
star topology. Furthermore, data link continues among normally-operating stations in a star topology.
Modules are configured into a line with Ethernet cables and without a switching hub. If an error occurs, the station in
Line topology
error and the stations after that will be disconnected from the network.
Modules are configured into a ring using Ethernet cables. Data link continues among normally-operating stations
Ring topology
without a switching hub.
Add/remove slave stations one by one. If multiple slave stations are added/removed at a time, all stations on the network will be
reconnected, resulting in a momentarily error in all the stations.
Station number and connection position
Modules can be connected in any order regardless of the station number.
Cascade connection
Up to 20-layer connection is available for the cascade connection.
Replacing CC-Link IE TSN devices
For star topology, slave stations can be replaced without powering off the whole system.
NOTE
• Refer to the Master Module User's Manual for detailed network configurations.
