Mounting
The Emerson 1410S Gateway should be mounted in a location that allows convenient
access to the process control network as well and provides good coverage for the wireless
field network.
The two Emerson 781S Smart Antennas should be mounted at the same height and be
spaced between 3–9 ft. (1–3 m) horizontally. This is to ensure that they provide identical
coverage for the wireless field network and to help eliminate coverage gap in the event of
a switch over.
Ethernet
An Ethernet connection to the host system will support Modbus
®
TCP, OPC, AMS Wireless
Configurator, and HART-IP
™
protocols. When using this architecture, connect the
secondary Ethernet port on Gateway A directly to the secondary Ethernet port on Gateway
B. Then connect the primary Ethernet ports for both Gateways to a process control
network using separate/redundant network switches. See Figure B-5.

Note
The primary Ethernet port for each network should be connected to separate network
switches on the same process control network. Consult a control system administrator for
more details about available redundant network switches.
