INDEX
SB0095 Reverse loop status SB0065 Loopback status
(No. changed)
• Although the CC-Link IE
controller network uses
two-core cables, loopbback is
performed even if a
disconnection or error is
detected on one side.
• The cause of loopback can be
checked by Own station's
loop status (SW0064).
SB0096
Reverse loop status of the
remote master station
— — —
Delete the sequence program
for the corresponding part.
SB0099 Forward loop loopback SB0065 Loopback status
(No. changed)
• Although the CC-Link IE
controller network uses
two-core cables, loopbback is
performed even if a
disconnection or error is
detected on one side.
• The station No. for the station
where a loopback is executed
can be checked by IN-side
loopback station No.
(SW0070).
SB009A Reverse loop loopback SB0065 Loopback status
(No. changed)
• Although the CC-Link IE
controller network uses
two-core cables, loopbback is
performed even if a
disconnection or error is
detected on one side.
• The station No. for the station
where a loopback is executed
can be checked by OUT-side
loopback station No.
(SW0080).
SB009C
Send transmission path
mismatch status
SB0065 Loopback status
(No. changed)
• The loopback is performed
when the send transmission
path is inconsistent in the
CC-Link IE controller network.
• The cause of loopback can be
checked by Own station's
loop status (SW0064).
