Checking with LED

This section describes troubleshooting with the LEDs of the RJ71GN11-T2.
When the RUN LED turns off
When the RUN LED turns off after powering on the RJ71GN11-T2, check the following.
Check item
Is the RJ71GN11-T2 mounted correctly?
If the above action does not solve the problem, perform the module communication test to check for hardware failure. (
Page 168 Module Communication Test)
When the ERR LED turns on or is flashing
When the ERR LED turns on or is flashing, check the following.
Check item
Does any error occur in the module diagnostics?
Is a data link faulty station displayed on the "CC-
Link IE TSN/CC-Link IE Field Diagnostics"
window?
Is Initialization failure (parameter mismatch
between master and slave stations) (event code:
00C71) registered in the event history of the
master station?
(A mismatch of the synchronization setting and
inter-module synchronization cycle may occur
between the master station and slave stations.)
Is the event code 00C81 registered in the event
history?
Is the event code 00C72 registered in the master
station event history?
Is the event code 00C80 registered in the event
history when "Connection Device Information"
under "Basic Settings" of the master station is set
to "Mixture of CC-Link IE TSN Class B/A" or "CC-
Link IE TSN Class A Only"?
If the above actions do not solve the problem, perform the following tests to check for an error.
• Module communication test ( Page 168 Module Communication Test)
Action
Securely mount the RJ71GN11-T2 on the base unit.
Action
Take the actions displayed on the window.
• Correct "Network Configuration Settings" and "Communication Period Setting" under "Basic Settings" of
the master station in accordance with the slave station actually connected.
• Perform troubleshooting for when the D LINK LED turns off or is flashing in the data link faulty station.
( Page 163 When the D LINK LED turns off or is flashing)
• When the communication speed of the data link faulty station is 100Mbps, the communication speed of
the master station is 1Gbps, and the data link faulty station is used under the multicast mode, connect
the data link faulty station to the device supporting the multicast filter. ( Manual of the device used)
Take the following actions for the slave station with the IP address displayed in the detailed information of
the event.
• For a local station, match "Fixed Scan Interval Setting of Inter-module Synchronization" in "Inter-module
Synchronization Setting" in "System Parameter" to the setting on the master side.
• Replace the device with a device supporting CC-Link IE TSN Class B network synchronous
communication.
• Match "Network Synchronous Communication" in "Network Configuration Settings" under "Basic
Settings" of the master station to the synchronization setting of the slave station.
Take the following actions for the slave station with the IP address displayed in the detailed information of
the event history.
• Match "CC-Link IE TSN Class Setting" in "Network Configuration Settings" under "Basic Settings" of the
master station to the CC-Link IE TSN Class of the slave station.
• Update the engineering tool to the latest version.
• Update the slave station firmware with the IP address displayed in the detailed information of the event
history to the latest version.
Take one of the following actions.
• Check 'Station protocol version 2.0 support status' (SW01A0 to SW01A7) and update the firmware of all
slave stations to a version that supports the protocol version 2.0. Alternatively, replace with slave
stations that support protocol version 2.0.
• For firmware version "15" or later, set 'Protocol setting' (Un\G1294018) of the master station to '1:
Protocol version 1.0 fixed'. ( Page 260 Protocol information (Un\G1294016 to Un\G1294031))
• After powering on the slave stations and the devices on the communication path, power on the master
station.
