10-4-2 Error Information Details
Message
Corrective Actions
NE1A-series Controller System Failures
System Failure
System failure
Replace the unit if the system failure still occurs after turning ON the
power supply again.
Invalid Configuration
Configuration invalid
Configuration differs from the original configuration. Reconfigure
after checking.
Logic Programming-related Errors
Function Block Status
Error
Function Block Status Error An incompatible signal input was set as an input condition in the
function block’s Set Parameters. Check the inputs entered in the
function block or the program logic.
DeviceNet Communications Errors
Switch Setting
Mismatch
Switch setting mismatch
Check that the node address is the same as the one in the last
configuration. If not, change back to the same node address or
reconfigure. If the error occurs again, replace the unit.
Duplicate MAC ID
Node address duplication
Check the node address of other nodes.
Correct the configuration so that each node address is used only
once and then cycle the power supply.
Network PS Voltage Low Network power supply
voltage low error
Check the following points:
• Make sure the power supply voltage is set within the specification
range.
• Make sure a cable or wire is not disconnected.
Bus Off
Bus OFF (Communica-
tions cut off by frequent
data errors.)
Check the following points:
• Make sure the baud rate is the same for all nodes.
• Make sure the cable lengths (of main/branch lines) are not too
long.
• Make sure a cable or wire is not disconnected or loose.
• Make sure terminating resistance is at both ends of the main line
and only at both ends.
• Make sure there is not a lot of noise.
• Make sure power is being supplied to the Slave.
Transmission Timeout
Transmission timeout
Standard I/O
Connection Timeout
Standard I/O connection
timeout
Relevant Safety I/O
communication stopped
because of a Safety I/O
communication error
The corresponding safety
I/O connection was
stopped due to a safety I/O
connection timeout.
All Safety I/O communi-
cation stopped because
of a Safety I/O communi-
cation error
All safety I/O connections
were stopped due to a
safety I/O connection time-
out.

Timeout
Safety I/O connection time-
out
Nonexistent Slave
Device
No slave
Safety I/O Connection
Establishment Failure
Safety I/O connection
establishment error
Check the following points on the slave device:
• Make sure it is configured.
• Make sure it is operating normally.
Invalid Slave Device
Unauthorized slave
device (verification error)
Verify the slave device (select
Device - Parameters - Compare
)
and connect a suitable slave device.
EM Transmission Error
(Duplicate MAC ID)
Unable to transmit due to
node address duplication.
Refer to the section on
Duplicate MAC ID
.
EM Transmission Error
(Invalid Header)
Unable to transmit due to
invalid header.
Check the following points:
• Node address of the transmission message
• Class ID of the transmission message
• Instance ID of the transmission message
EM Transmission Error
(Device Offline)
Unable to transmit
because local device is not
on the network.
Check the following points:
• Make sure the baud rate is the same for all nodes.
• Make sure the cable lengths (of main/branch lines) are not too
long.
• Make sure a cable or wire is not disconnected or loose.
• Make sure terminating resistance is at both ends of the main line
and only at both ends.
• Make sure there is not a lot of noise.
• Make sure the power supply voltage for the network power source
is set within the specification range.
EM Transmission Error
(Message ID Error)
Unable to transmit due to
message ID error.
EM Transmission Error
(Response Timeout)
Unable to transmit due to
response timeout.
