O
VERVIEW
The SEL-351P Recloser Control supports Distributed Network Protocol (DNP) V3.00 L2 Slave
protocol. This includes access to metering data, protection elements (Relay Word), contact I/O,
targets, sequential events recorder, breaker monitor, relay summary event reports, settings
groups, and time synchronization. The SEL
-
351P supports DNP point re-mapping.
C
ONFIGURATION
To configure a port for DNP, set the port PROTO setting to DNP. Although DNP may be
selected on any of the available ports, DNP may not be enabled on more than one port at a time.
The following information is required to configure a port for DNP operation:

The RTS signal may be used to control an external transceiver. The CTS signal is used as a
DCD input, indicating when the medium is in use. Transmissions are only initiated if DCD is de-
asserted. When DCD drops, the next pending outgoing message may be sent once an idle time is
satisfied. This idle time is randomly selected between the minimum and maximum allowed idle
times (i.e., MAXDLY and MINDLY). In addition, the SEL
-
351P monitors received data and
treats receipt of data as a DCD indication. This allows RTS to be looped back to CTS in cases
where the external transceiver does not support DCD. When the SEL
-
351P transmits a DNP
message, it delays transmitting after asserting RTS by at least the time in the PREDLY setting.
After transmitting the last byte of the message, the SEL
-
351P delays for at least PSTDLY
milliseconds before deasserting RTS. If the PSTDLY time delay is in progress (RTS still high)
