MicroLogix 1400 Distributed Network Protocol (DNP3) Appendix F
Word offset 7, 27 and 47 reflect the Error Codes that have been caused in the
sessions for DNP3 TCP Server, UDP and TCP Client respectively. The
following table lists the possible ranges of the Error Code. Any others are
reserved.
73 Transport Function Layer Error Codes:
0: NO_ERROR - No error found in the Transport Layer.
1: DISCARD_NOT_FIRST_SEG - The received packet was discarded
since it was not a first segment.
2: DISCARD_DUPLICATED_AND_MORE_SEG - The received packet
was discarded since it had the same sequence number as previous,
more segments are expected.
3: DISCARD_DUPLICATED_AND_FINAL_SEG - The received packet
was discarded since it had the same sequence number as previous,
final segment received.
4: DISCARD_OUT_OF_ORDER_SEG - The received packet was
discarded since the sequence number was out of order.
