The Ethernet port supports three simultaneous sessions that can include any
combination of Telnet, Modbus
®
, or DNP3, but supports a maximum of one
DNP3 LAN/WAN session. If an application requires two DNP3 sessions, the
SEL-734 supports one DNP3 LAN/WAN session and one DNP serial session.
Protocol selection for the Ethernet port is determined via the port number on
which requests arrive. The protocols supported on the Ethernet port are
SEL-ASCII, MODBUS/TCP, and DNP3 LAN/WAN.
The Ethernet port has two LEDs, which indicate the status of the port.
Table 10.5 describes each LED. Figure 10.3 shows the location of status
LEDs.

IRIG-B
Two options for IRIG-B signal input are given, but only one should be used at
a time. IRIG-B (01 and 02) inputs, or an SEL Communications Processor via
Serial Port 3 may be used (see Table 10.6 and Figure 10.7). The available
communications processors are the SEL-2032, SEL-2030, SEL-2020, and the
SEL-2100 Logic Processor (see Table 2.3).
