Explicit Message Communications Errors
When there is a problem with a request message sent from the master in explicit communications, the drive will return a
response message with 94 as the service code well as one of the following error codes as the data.
Note: Refer to the MEMOBUS/Modbus Data Table in Appendix C of the technical Manual for the drive the DeviceNet Option is
connected to for a list of monitor data using the MEMOBUS/Modbus message area.

DeviceNet Option Error Codes
„
DeviceNet Option Fault Monitors U6-98 and U6-99
The DeviceNet Option SI-N3 can declare the error/warning conditions via drive monitor parameters as shown in
Table 22 .
Table 22 DeviceNet Option Fault Monitor Descriptions
Two drive monitor parameters, U6-98 (OPTN LATCH STAT) and U6-99 (OPTN ACTIVE STAT), assist the user in
network troubleshooting.
• U6-98 displays the first declared fault since the last fault reset or power cycle.
• U6-99 displays the present DeviceNet Option SI-N3 status.
These parameters are accessible from the DeviceNet network the or the drive digital operator. A drive fault reset or
power off clears and refreshes both U6-98 and U6-99.
Note: In the event of a PLC idle state, the action taken by the DeviceNet Option SI-N3 depends upon the value of parameter F6-54
(Idle Mode Fault Detection).
Error Code Description Cause Possible Solution
08FF Service not supported The service code is incorrect. Correct the service code.
09FF Invalid attribute value The attribute is incorrect. Correct the attribute.
0CFF Object state conflict
Attempted to change a drive constant that
cannot be changed while the drive is running.
Stop the drive.
0EFF Attribute not settable Attempted to change a read-only attribute. Correct the service code or attribute setting.
13FF Not enough data The data size is incorrect. Correct the data size.
14FF Attribute not supported
Attempted to execute a service that is not
defined for the attribute.
Correct the service code or attribute setting.
15FF Too much data The data size is incorrect. Correct the data size.
16FF Object does not exist An unsupported object was specified. Correct the class or instance setting.
1FFF Vendor specific error
Attempted to change a drive constant that
cannot be changed while the drive is running.
Attempted to change a drive constant to a
value outside of the setting range.
Stop the drive.
Specify a value that is within the setting range.
20FF Invalid parameter
Attempted to change to a data value outside
of the setting range.
Specify a data value that is within the setting range.
