Assumed cause
A slave that is in the network con-
figuration information is not con-
nected.
There is a node address mis-
match.
A different slave from the one that
is specified in the network config-
uration information is connected.
A slave that is not in the network
configuration information is con-
nected.
Cause and
The hardware switches for the
correction
slave node address were
changed to a value other than 0
after the Write Slave Node
Address operation was per-
formed from the Sysmac Studio.
The Ethernet physical layer is
broken between two slaves.

3 Error Descriptions and Corrections
Correction
Connect the slaves that are in the
network configuration informa-
tion. Or, connect the Sysmac Stu-
dio and set and save the network
configuration information with the
slave deleted in the master.
Make the slave node address set-
tings consistent with the network
configuration information.
Connect the slave that is speci-
fied in the network configuration
information. Or, connect the Sys-
mac Studio and set and save the
network configuration informa-
tion with the correct slaves in the
master.
Disconnect the slave that is not in
the network configuration infor-
mation from the network. Or, con-
nect the Sysmac Studio and set
and save the network configura-
tion information with the slave
added in the master.
To use the value that is set on the
hardware switches, reset the
error. When the error is reset,
there will be a disagreement
between the hardware switches
and the value that was written
from the Sysmac Studio. A Slave
Application Error (84280000 hex)
will occur and you must then
reset the error again.
If this error occurs when the slave
is disconnected or disabled, reset
the error first and then connect or
enable the slave. When you do, a
Slave Application Error
(84280000 hex) will occur. Reset
the error again and then connect
or enable the slave.
To use the node address that was
set from the Sysmac Studio, set
the hardware switches to a node
address of 0 and cycle the power
supply to the slave.
In cases not caused by the above
causes, confirm the location of
the break in the Ethernet cable
and replace the cable.
Prevention
Set and save the network config-
uration information for the config-
uration actually connected in the
master.
To use the value that is set on the

or enable the slave.
To use the node address that was
