Wiring for use of the CC-Link IE Field Network (FR-
A800-GF)

2.11.1 System configuration example

• Mount the "RJ71EN71", "RJ71GF11-T2", "QJ71GF11-T2", or "LJ71GF11-T2" type CC-Link IE Field Network master/local
module on the main or extension base unit having the programmable controller CPU used as the master station.
• Connect the CC-Link IE Field Network programmable controller (master station) to the inverter with an Ethernet cable.

2.11.2 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
Star topology
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 error
Line topology
and the stations after that are disconnected from the network.
Modules are configured into a ring using Ethernet cables. Data link continues with the stations that are operating normally.
Ring topology
A switching hub is not required.
*1 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 Field Network devices
• For star topology, slave stations can be replaced without powering off the whole system.
NOTE
• Refer to the MELSEC iQ-R, MELSEC-Q, or MELSEC-L CC-Link IE Field Network Master/Local Module User's Manual for the
detailed network configurations.
