DNP3 Outstation Profile Configuration

Determine how the EDS001 will be expected to interact with its DNP3 Master(s). Note that
the EDS001 may be expected to interact with more than one master and on more than one
LAN. The maximum is eight DNP3 Masters per LAN. The cumulative expectations of all the
interested DNP3 masters will determine the DNP3 Outstation configuration. The DNP3
Outstation has only one instance of data that it serves.
As a DNP3 Outstation, the EDS001 will have one profile, and it must be configured via the
RX3i CPU before it can operate on the DNP3 network. The COMMREQ outlined in Chapter 6
is used for this purpose. It conveys all DNP3 Outstation parameters from the RX3i CPU to
the EDS001. The COMMREQ is executed only once to initialize the EDS001. See also
Appendix A: for a full definition of all applicable DNP3 Outstation parameters.
Once configured and connected to its DNP3 Master(s), the EDS001 will exchange data
automatically per its configuration and that of its masters.
RX3i CPU memory needed for DNP3 Outstation data can optionally be configured into the
EDS001 module using a single startup COMMREQ, as documented in Chapter 6. The
Outstation configuration is permitted to use %I, %AI, %Q, %AQ, %R, %W, %M, %T and %G
memory types, as documented in Chapter 6. Ranges should be selected to accommodate
the amount of data involved, but not overflow the end-point of the memory type.
The Outstation configuration file also includes parameters to define an area of PLC memory
for master station-Outstation communication status, if required. The format of the
Outstation Status Space is defined in Section 6.3.1
