Appendix F MicroLogix 1400 Distributed Network Protocol
Implementation Table The MicroLogix 1400 controller supports DNP3 Certification Subset Level 2.
Table 37
identifies which object groups and variations, function codes and
qualifiers the device supports in both requests and responses. The Request and
Response columns identify all requests and responses that may be sent/parsed
by a DNP3 Master, or must be parsed/sent by the controller.
The implementation table lists all functionality required by either DNP3
Master or controller as defined within the DNP3 IED Conformance Test
Procedures. Any functionality beyond the highest subset level supported is
indicated by grayed table cells.
Request 27 (0x1B) FC_DELETE_FILE Yes Controller parses
Request 28 (0x1C) FC_GET_FILE_INFO No Controller parses
Request 29 (0x1D) FC_AUTHENTICATE_FILE Yes Controller parses
Request 30 (0x1E) FC_ABORT_FILE No Controller parses
Request 31 (0x1F) FC_ACTIVATE_CONFIG No Controller parses
Request 32 (0x20) FC_AUTHENTICATE_REQ No Controller parses
Request 33 (0x21) FC_AUTHENTICATE_ERR No Controller parses
34 (0x22)…128 (0x80) No Reserved.
