(5) Diagnostic function
Function Description Reference
Communication within the same
network
Transient transmission is performed to other stations using
dedicated instructions and GX Developer.
Page 152, CHAPTER 10
Communication with different networks
By setting the routing parameters (communication path) using GX
Developer in advance, transient transmission can be performed to
stations on different networks through dedicated instructions or GX
Developer. Seamless communication is available with the following
networks.
• Ethernet
• CC-Link IE Controller Network
• MELSECNET/H
• MELSECNET/10
• CC-Link (when using GX Developer)

Function Description Reference
Slave station disconnection
Only the slave station where an error occurs is disconnected, and
data link continues with the stations that are operating normally.
In a line topology, all stations connected after the faulty station are
disconnected.
Automatic return
When the station disconnected from the network due to a data link
failure recovers, it automatically returns to the network and restarts
data link (for standard communication only).
Loopback function
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.

Function Description Reference
CC-Link IE Field Network diagnostics
The status of CC-Link IE Field Network can be checked by GX
Developer. The faulty area, cause of the fault and its corrective
action, and event history can be checked in GX Developer.

diagnostics
Communication test
Check whether the communication path for transient transmission
from the own station to the target station is correct.
