Control station switching
Even if the control station goes down, a normal
station (sub-control station) takes over the control to
continue data link.
Loopback
Any disconnected cable or faulty station is isolated
from the network, and data link can be continued
among normally operating stations.
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.
Cable fault detection
A cable fault can be detected as a cause of a
communication error.
Cable insertion error detection
Incorrect cable connection between OUT and IN can
be detected as a cause of loopback or disconnection
from the network.
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.
External power supply
The external power can be directly supplied to the
CC-Link IE controller network module with external
power supply function.
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.
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.
