Appendix 7 Comparison of CC-Link and CC-Link IE Field Network
Description
Mode selection for cyclic This mode can be selected for optimizing the performance of
transmission cyclic transmission based on the frequencies of cyclic
transmission and transient transmission. The mode can be
selected from "Online (Normal mode)" and "Online (High-
speed mode)".
Seamless transmission with Setting the routing parameters beforehand also enables
different networks transient transmission to stations in different networks.
Communication is also possible with the CC-Link IE Controller
Network, and MELSECNET/H.
Network configuration The network configuration can be checked by the CC-Link IE
display Field Network diagnostics of CC-Link IE Field Utility.
Loop test Check the network circuit status and parameter setting status
of each station.
Cable test Check the connection status of the Ethernet cable.
Communication test Check whether the communication path for transient
transmission from the own station to the target station is
correct.
Network event history The history of events that occurred in the own station and on
the network is displayed. For the master station, the event
history of the entire network can be displayed, and so it can be
used for troubleshooting at network start-up.
Reserved station temporary Reserved stations can be temporarily disabled without
disablement changing parameters.
Notes during replacement
When the CC-Link IE Field Network is connected in a line topology, stations after the disconnected station
become data link faulty stations. To prevent disconnection of normal stations, connect the CC-Link IE Field
Network in a star topology. (Page 21 Network configuration)
No standby master function is available in the CC-Link IE Field Network board.
The setting is fixed to "Continue" for CC-Link IE Field Network.
