Error Messages
The following table lists in alphabetical order the error messages that might be displayed during operation along
with recommended error processing. An asterisk indicates errors that are defined in DeviceNet. The four-digit hex-
adecimal number after some error messages is the error code.
Error message
Error processing
Bus Off occurred. Execute on-line process
again.
A bus-off error (communications stopped because of too many
communications errors) occurred in the network. Make an online
connection again.
OUT and IN areas duplicated.
The output and input areas overlap in the Master parameter settings.
xxxxxxxx in integer XX to YY.
Input an integer value between XX and YY for xxxxxxxxxx.
xxxxxxxx in integer.
Input an integer value for xxxxxxxxxx.
Access Violation.
* The parameter is incorrect. Check the parameter setting.
Wrong Attribute Data.
* The parameter is incorrect. Check the parameter setting.
Writing Attribute Data failed.
* The specified data couldn’t be written. Check the command and the
other node’s operating status and try executing the command again.
Parameters to be printed not set.
The parameters specified for printing do not exist. Specify the
parameters correctly.
Printing can not be started.
The printing process could not be started.
Out of area or setup impossible area.
The specified data area was exceeded or couldn’t be specified. Set
the data area correctly.
Writable Parameters not exist.
All of the parameters are read-only.
2 bytes or more can not be Allocated to odd
address.
The starting byte can’t be set to “High” when two or more bytes are
required. Either change the data size or start with the “Low” byte.
Class and Instance not set correctly.
The specified class or instance data is incorrect. Set correct data.
This offset can not be specified from current
start word.
The specified offset value causes the range to be exceeded. Specify
an offset that doesn’t exceed the range.
Can not execute in current device mode.
* The specified command cannot be executed in the device’s current
mode. Change the device’s mode.
The Master parameters can’t be set unless the PC is in PROGRAM
mode.
Can not execute in current mode.
* The specified command cannot be executed in the current mode.
Check the PC’s or Unit’s mode.
The Master parameters (scan list) can’t be set while Master
parameters (scan list) are being set.
This node address being used by Master Unit
or Configurator.
A Master Unit or the Configurator is already using the specified node
address. Specify another node address.
Part or all of specified area Allocated to other
block.
All or part of the specified memory block area is already allocated to
another memory block area. Either specify a different area or change
the settings of the other memory block area.
Part or al of specified area Allocated to other
block, so can not used. To use, change other
block’s setup.
All or part of the memory block area is already allocated to another
memory block area. Either specify a different area or change the
settings of the other memory block area.
Specified Attribute Data not written.
* The specified data couldn’t be written. Check the command and the
other node’s operating status and try executing the command again.
Specified attribute not supported.
* The parameter is incorrect. Check the parameter setting.
Specified Attribute read only.
* The data is read-only. Check the parameter.
Specified object not found.
* The parameter is incorrect. Check the parameter setting.
Specified service not supported.
* The specified service is not supported by the other node. Check the
other node’s functions.
Specified slave has valid IN Data. Before
registering, define valid IN Memory Block.
The Master parameter wizard could not allocate I/O memory to a
Slave that requires input data because there is no input memory
block. Define a usable input memory block to register the Slave.
