D.1 Overview
Redundancy for the Smart Wireless Gateway increases the availability of the wireless field
network by providing two sets of physical hardware which operate as a single Gateway system.
This section covers setup and installation of a redundant Gateway system. It also covers
diagnostics and integration to help monitor the health of the redundant Gateway system.
Where to mount the respective antennas
Illustration of maximum redundancy including dual switch and UPS
Understanding how the fail over works and experience to expect
How to leverage the multimaster capability for Modbus
®
integrations
D.2 Requirements
Smart Wireless Gateway
Firmware Version 4.3.19 or greater is recommended
RD option for Gateway Redundancy
Static IP Address
Must have matching output protocols (e.g. Modbus or OPC) on each Gateway.
Host system
Ethernet connection for Modbus TCP or OPC DA communications
Serial (RS-485) connection for Modbus RTU communications
D.3 Setup
When configuring redundant Smart Wireless Gateways, it is only necessary to configure one
system. The other Gateway will be configured automatically when it is paired with the first
Gateway.
