ONFIGURATION
The SEL-2711 has two connectors which are accessible from the rear of the host device, as shown
in Figure 3.1. The connectors provide for redundant Modbus Plus connections and are referred to
as ports A and B. See
Modbus Plus Network Planning and Installation Guide
for more
information on using redundant connections in a Modbus Plus network. In a typical non-redundant
system, either port may be used.
There are many considerations when planning a Modbus Plus network. See
Modbus Plus
Network Planning and Installation Guide
for complete information on designing and connecting
Modbus Plus network.
