Checking the Network Status

This section describes troubleshooting to check the status of the network by executing diagnostics and operation tests using
the engineering tool.

CC-Link IE TSN/CC-Link IE Field Diagnostics

For CC-Link IE TSN, perform status monitoring, operation tests, or others.
Precautions
In the following cases, the CC-Link IE TSN/CC-Link IE Field diagnostics cannot start.
• The RJ71GN11-T2 is not connected to CPU modules specified on the "Specify Connection Destination Connection"
window.
• In CPU parameters of CPU modules specified on the "Specify Connection Destination Connection" window, "Link Direct
Device Setting" of "Memory/Device Setting" is not "Extended Mode (iQ-R Series Mode)".
• "Module Operation Mode Setting" under "Application Settings" of the RJ71GN11-T2 is not in the online mode.
• The 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.
Diagnostic items
When starting the CC-Link IE TSN/CC-Link IE Field diagnostics by specifying "No Specification" in "Other Station Setting" on
the "Specify Connection Destination Connection" window, the following items can be used.

Operation
*1 If the setting on the "Specify Connection Destination Connection" window of the engineering tool is as follows, remote operation cannot
be executed with "All Stations Specified".
Connection via Ethernet with the selections "Ethernet Board" for the personal computer-side I/F and "CC IE TSN/Field Module" for the
programmable controller-side I/F
Overview
Check if any errors are being caused by
the devices and cables that configure the
network. In addition, check the operating
status of each station.
Check that there is no station that is set on
an actual network.
Check details of, or actions for, errors that
occurred in a selected station.
Check whether outgoing/incoming paths
of transient transmission between the own
station and the communication target are
correct.
Check information of the slave stations
which are performing data link in list form.
Operate remotely from the engineering
tool to slave stations.
