EtherNet/IP Configuration

Network topology
EtherNet/IP consists of the FX5-ENET/IP (1) and EtherNet/IP devices (2).
For the FX5-ENET/IP, configure the network in star topology, or line topology using the Ethernet cables. Ring topologies are
not possible.
■Star topology
The network is configured into a star shape using a switching hub and Ethernet cables.

• In EtherNet/IP, other external devices that perform TCP/IP communications can be used with the devices on
the same network.
• Up to 33 units can be connected in line topology.
Scanner and adapter
In EtherNet/IP, station types are separated into scanner and adapter.
Station type Description
Scanner A station type of EtherNet/IP that corresponds to the master station. The scanner has the control information and controls the
overall network.
Devices that have a connection of originator or target can be operated as the scanner.
Adapter A station type of EtherNet/IP that corresponds to slave stations. The adapter indicates stations other than the scanner.
Devices that have a connection of target can be operated as the adapter.
