Description of error
Take measures with referring to the QCPU User's Manual (Hardware Design,
Maintenance and Inspection).
Take measures referring to the troubleshooting section of the Serial
Communication Module User's Manual.
Take measures referring to the troubleshooting section of the CC-Link System
Master/Local Module User's Manual.
Take measures referring to the troubleshooting section of the Ethernet Interface
Module User's Manual.
Take measures referring to the troubleshooting section of the CC-Link IE Field
Network User's Manual.
Take measures referring to the troubleshooting section of the CC-Link IE
Controller Network Reference Manual.
Wait until SB0047 (baton pass status) and SB0049 (data link status) turn off
(normal).
Check the condition of the control station's power supply and of the cables and
the status of the control station CPU module.
Check the line status for a faulty cable or a missing terminating resistor, as well
as the stations that are not powered on.
In the case of the PLC to PLC network, when transient transmission is
executed frequently and the link scan time may exceed 200 ms, adjust the
transient setting values to reduce the link scan time.
Check for duplicate station numbers and control stations with the setup
confirmation test.
If the setup confirmation test cannot be executed, identify the station where a
data link error has occurred in [Data-link status of each station] on the Other
station information screen of network diagnostics and then check the station
No. setting and parameters of the error station.
Check for faulty cables, wire breakage, poor connector connections, connection
errors, uninstalled or loose terminating resistors, etc.
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
