Series 90B ANNUNCIATOR INSTALLATION AND CONFIGURATION MANUAL
APPENDIX C
DNP DATA FORMATS
The DNP Communication option is used to transmit point status (Binary Inputs)
to other devices. When the SER time-stamped alarms option is enabled, a
historical record of binary input change events and the time at which they
occurred can also be sent. The DNP Communications work in a slave mode and
operate over RS-232/485 or Ethernet. The DNP implementation is outlined in
the Device Profile Document.

Supported (the complete list is described in the attached table):
For static (non-change-event) object requests, request qualifier codes 00 and 01 (start-stop),
and 17 and 28 (index) are supported in addition to request qualifier code 06 (no range – or all
points). Static object requests received with qualifiers 00, 01 or 06, will be responded to with
qualifiers 00 or 01. Static object requests received with qualifiers 17 or 28 will be responded
to with qualifiers 17 or 28. For change-event object requests, qualifier codes 06 (no range)
and 07 and 08 (limited quantity) are supported. Qualifiers 17 or 28 are always returned.
