Chapter 6 Micro870 Controller Distributed Network Protocol
Implementation Table Micro870 (2080-L70E-24QxBN) controllers supports DNP3 Certification Subset Level 2.
Table 12
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.
