10.3 Checking the Network Status
The network status is checked and troubleshooting is performed by using the CC-Link IE TSN/CC-Link IE Field diagnostics to
check the network status and error definition and by performing an operation test to check communications.
CC-Link IE TSN/CC-Link IE Field diagnostics
For CC-Link IE TSN, perform status monitoring, operation tests, or others.
In the following cases, the CC-Link IE TSN/CC-Link IE Field diagnostics cannot start.
• The FX5-CCLGN-MS is not connected to FX5 CPU modules specified on the "Specify Connection Destination Connection"
window.
• "Module Operation Mode" under "Application Settings" of the FX5-CCLGN-MS is not set to online mode.
• The module error (error code: 20E0H) occurs.
• The engineering tool is not connected to a station with the same communication speed as the master station.
• The network topology of the diagnostics destination does not support the version of the engineering tool or module.

monitor function
Network map • Displays the network configuration of CC-
Link IE TSN. This function displays the
current status of the same network as a
network map, and displays the Ethernet
cable connection status, IP address
duplication, and station disconnection
status. A network map to be displayed is
automatically generated from the current
configuration on the network.
• Whether an error occurred in any of the
devices and Ethernet cables that configure
the network can be checked. In addition,
the operating status of a station set in the
network parameters can be checked.

Monitor
• Displays the module status and
communication status of the selected
station. If an error occurred in the module,
this function displays diagnostic
information such as the cause of the error
and corrective action.
• Detailed error definition of the selected
station and corrective action for the error
can be checked.
Data Unlinked • Displays a station with its setting existing in
the network parameters but not displayed
in the network map (a station that has
never joined the network).
• This function can check the non-existence
of a station set in the network parameter.
