5.11.2 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.
