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.
Execute a setup confirmation test to check whether the same station number
has been set for two or more stations or whether two or more control stations
exist.
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.
<During execution of an online test>
Wait until SB0047 (baton pass status) and SB0049 (data link status) are
recovered.
<During execution of an offline test>
Change the switch setting to online after the test has been completed.
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
Review the station number setting.
The setup confirmation test of network diagnosis is effective.
Review the mode setting, and change it to online.
Check for faulty cables, faulty hardware, incorrect cable wiring, and absence of
terminating resistor (in the case of the bus). In addition, check whether the
same station number has been set for two or more stations or whether two or
more control stations or remote master stations exist.
The setup confirmation test and loop test of network diagnosis are effective.
