DNP-R-2F/FC-K
Functional description
The DNP R-2F/FC are network nodes that support intelligent infrastructure monitoring
of the hybrid and Optic Fibre network bus with RS-485 CIE interface ports A1 and A2.
Figure 2: Design Structure Diagram
The DNP R-2F/FC functions as a PASSIVE dual port Optic Fibre / RS-485 medium
converter.
The DNP R-2F/FC can operate in a mode with two optic fibre interfaces (2F) located on
ports B and C and also in a mode with a single optic fibre interface and an RS-485
interface (FC or CF).
In hybrid mode (FC /CF) the optic fibre interface on the DNP R-2F/FC can be
configured as either port B or C by selecting the correct rotary switch setting as per
Table 10. When used to support an optic fibre link in a class A bus configuration, one
of the
DNP R-2FC modules would require a port swap to support the standard port B to C
connection format around the closed ring. An example of this is illustrated in Figure
10b.
