9.4 Mounting and connections
Redundant Gateways follow similar mounting and connection practices as a standalone
Gateway. Refer to
Mounting the Gateway for more information. In addition to the
standard practices, the following considerations should be taken when installing
redundant Gateways.
Mounting
The Emerson 1410H 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 781 Field Links 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 9-6 .
