Control station switching
Even if the control station goes down, a normal
station (sub-control station) takes over the control
to continue data link.
Page 124,
Section 4.4.1
Loopback
Any disconnected cable or faulty station is isolated
from the network, and data link can be continued
among normally operating stations.
Page 125,
Section 4.4.2
Automatic return
When a station disconnected from a network due
to a data link error recovers from the error, the
station is automatically reconnected to the network
and restarts data link.

Section 4.4.3
Cable fault detection
A cable fault can be detected as a cause of a
communication error.
Page 127,
Section 4.4.4
Cable insertion error detection
Incorrect cable connection between OUT and IN
can be detected as a cause of loopback or
disconnection from the network.
Page 128,
Section 4.4.5
Detection of duplicated control station
or station No.
Duplication of the control station or station No. can
be detected as a cause of loopback or
disconnection from the network.

Section 4.4.6
External power supply
The external power can be directly supplied to the
CC-Link IE Controller Network module with
external power supply function.
Page 134,
Section 4.4.7
Detection of time of transient
transmission error completion
The time at which a transient transmission by a link
dedicated instruction failed can be detected, and
network No. and station No. of the station where
the error is detected can be confirmed.

CHAPTER 9
Transient transmission in the case of a
CPU module error
Transient transmission can be performed to
another station even if an error has occurred in the
CPU module of the station.
