Description
Only the station where an error occurs is
disconnected, and data link continues with the
stations that are operating normally.
All stations after the faulty station are
disconnected in line topology.
By using the loopback function with ring
topology, data link continues with the stations
that are operating normally.
Connecting the master station and submaster
station on the same network allows the
submaster station to continue controlling slave
stations instead of the master station even if the
master station is disconnected. Using this
function prevents the entire network from going
down due to disconnection of the master station.
Description
The status of CC-Link IE Field Network can be
checked using GX Works2. The error locations,
error causes, corrective actions, and event
history can be checked in GX Works2.
The internal hardware of the master/local
module can be checked.
The communication circuit in the transmission
system of the master/local module can be
checked.
The network line status and parameter setting
status of each station are checked.
Connection status of the Ethernet cables is
checked.
Whether the communication route for transient
transmission from the own station to the
destination station is correct or not is checked.
When the IP packet transfer function is used,
whether no error occurs in the communication
route is checked.
