Application Layer Errors
Error Code Name Description
1000 Device index invalid The device index in the request or response message
is not found in the slave list.
1001 Duplicate request in
application layer queue
The newly submitted message to the application layer
already exists in the queue. The message is ignored.
1002 COM port device removed
from system
The communication port for the message has been
uninstalled on the system. This error should never
occur as the communication ports are only uninstalled
when the module's program is terminated.
1003 Sequence number error The application sequence number in the response
message does not match that based on the last
request message. This indicates application layer
messages are received out of order.
1004 Response to select before
operate does not match
The select response message received from the slave
module is not that expected from the last select
request. This indicates a synchronization problem
between the master and slave devices.
1005 Response does not contain
date/time object
The response message from the slave device does
not contain a date/time object. The master expects
this object for the response message.
1006 Time-out condition on
response
The slave device did not respond to the last request
message from the master within the time-out set for
the IED device. The application layer time-out value is
specified for each IED unit in the slave configuration
table in the module. This table is established each
time the module performs the restart operation.
1007 Function code in application
layer message not
supported
The function code returned in the response message
is not valid for the application layer or not supported
by the module.
1008 Read operation not
supported for
object/variation
The application layer response message contains an
object that does not support the read function.
1009 Operate function not
supported for the
object/variation
The application layer response message contains an
object that does not support the operate function.
1010 Write operation not
supported for the
object/variation
The application layer response message contains an
object that does not support the write function.
Use the error codes returned for each command in the list to determine the
success or failure of the command. If the command fails, use the error code to
determine the cause of failure.
