Basler Electric BE1-11 DNP3 Protocol - Manual (Page 17)

DNP Settings
This chapter describes configuration settings that must be set to enable the BE1-11 to support DNP.
Selection of DNP Protocol
Selection of DNP protocol is predetermined by the BE1-11 style number. BE1-11 Protection Systems that
support the DNP protocol must have a style number with the fifth character being the letter D (via RS-485)
or the sixth character being the number 3/4 (via Ethernet). This can be verified by reading the BE1-11
style number using BESTCOMSPlus
® or the front panel interface. Reference the BE1-11 instruction
manual.
Since the BE1-11 has only one set of DNP data change buffers and connection information, only one
DNP master can actively communicate with the BE1-11 at one time as set by the BE1-11 style number.
DNP settings are configurable through BESTCOMSPlus and the front panel. Certain settings can only be
configured through BESTCOMSPlus, such as analog and binary input points mapping to user-mapped
lists and scaling settings for analog inputs and analog output status points.
Deadbands for analog inputs and class assignments for events are configured only through DNP object
34 and DNP Assign function.
For more information about changing the BE1-11 parameters, refer to the appropriate BE1-11 instruction
manual.
