 RFID-related Errors
When the ERR indicator lights, check the LED indicators from bit 7 to bit 0 or the error output for errors
relating to RFID, and then take suitable actions
Error Corrective action
Lit red Hardware error If the error continues after resetting the power, replace the DeviceNet Remote ID
Controller.
Flashing red Settings error Set the node address switches within the correct range.
Error Corrective action
Lit red Duplicate node address Assign unique node addresses to all nodes within the same network.
Flashing red Leaving link Check whether the communications cable is connected correctly. If noise enters
on the communications cable, the node made leave the link. Take suitable noise
countermeasures.
Indicator Output bits Error Corrective action
Bit 0
Flashing red
Error
Termination + ID
Tag Missing
Error
An ID Tag could not be
detected in Trigger Mode.
Change the control timing so that communications can be started
while the ID Tag is within the Antenna's communications range.
Measure the noise and take suitable noise countermeasures.
Check the effect of surrounding metal and make sure that the
desired communications distance can be obtained.
Bit 1
Flashing red
Error
Termination + ID
Tag Missing
Error
ID Tag was detected in
Trigger Mode but
communications could
not be ended normally.
Change the control timing so that communications can be started
while the ID Tag is within the Antenna's communications range.
Measure the noise and take suitable noise countermeasures.
Check the effect of surrounding metal and make sure that the
desired communications distance can be obtained.
Bit 2
Flashing red
Error
Termination +
Address Error
The command specified
a memory area outside
the ID Tag memory
range.
Set the command memory area within the ID Tag memory range.
Bit 3
Flashing red
Error
Termination +
Protection Error
The command specified
data to be written to the
write-protected area of ID
Tag.
Set the command memory area to outside the write-protected
area.
Bit 4
Flashing red
Error

Mismatch Error
Data was not correctly
written to ID Tag.
Retry the writing process.
If the error persists, replace the ID Tag.
Bit 5
Flashing red
Error
Termination + ID
System Error 1
ID Tag used is not
supported by the
DeviceNet Remote ID
Controller.
Change the ID Tag to one supported by the DeviceNet Remote
ID Controller.

Error
Termination + ID
System Error 2
Bit 0 and bit 4
Flashing red
Error
Termination +
Command Error
There is an error with the
execution command, or
the command cannot not
be received.
Check the command, address, and number of bytes to process.
