(3) Storage of the error codes of the link dedicated instruction
Check the error code generated when the link dedicated instruction is executed
through the device data below.
The error codes of the transient transmission are also stored in the link special
registers SW00EE to SW0FF.
For the details of the REMFR/REMTO instruction, refer to the description on the
programming of link dedicated instructions in section 7.1.1.
For details about READ/WRITE instructions, refer to the Q-corresponding
MELSECNET/H network system reference manual (PLC to PLC network).

Take measures referring to the troubleshooting section of 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.
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.
Check for faulty cables, wire breakage, poor connector connections, connection
errors, uninstalled or loose terminal 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.
