*1 The 7-segment indicator will alternate between the Unit's node address and the code given in the tables in this section.
*2 When a (master function) structure error or verification error occurs, only the most recent error is displayed for each slave.
If the Unit is set to stop the remote I/O communications for a communications error, two errors can be displayed: The
slave's communications error and its most recent error.

Likely cause
The CX-Integrator is set to
check the vendor and the
slave's vendor does not
match the registered scan
list. (Occurs with the scan
list enabled.)
The connection path was
set with the CX-Integrator
and there is a mistake in
the connection path setting
in the scan list. (Occurs
with the scan list enabled.)
The slave's I/O data size
does not match the regis-
tered scan list. (Occurs
with the scan list enabled.)
The CX-Integrator is set to
check the device type and
the slave's device type
does not match the regis-
tered scan list. (Occurs
with the scan list enabled.)
The CX-Integrator is set to
check the product code
and the slave's product
code does not match the
registered scan list.
(Occurs with the scan list
enabled.)
The device does not sup-
port the I/O service speci-
fied in the scan list.
(Occurs with the scan list
enabled.)
A timeout occurred during
remote I/O communica-
tions using the master
function. (The response
from the slave timed out 6
consecutive times.)
