Redundant Gateway systems
September 2020
Power
Power for the redundant Gateways should be applied after all primary and secondary
Ethernet and RS-485 connections have been made. Using separate uninterruptable power
supplies (UPS) is recommended to ensure availability of the redundant Gateway system.

Diagnostics

The redundant system will perform many diagnostic checks to verify the health and
connectivity of the system. In the event of a failure, it can take up to 30 seconds for the
Gateway to trade positions.
These diagnostics can also be mapped to Modbus
table covers what diagnostics are included on the Redundancy Status page as well as how
they can be mapped as parameters in Modbus or OPC.

In addition to the redundancy diagnostics, an additional check may be configured to test
network connectivity to a host system or other application. The redundant system will use
this check to determine the best connectivity option and which Gateway should be set to
the active Gateway.
To configure network connectivity check:
1. Navigate to System Settings → Gateway → Ethernet Communication.
2. Enter the host system IP address in the Check Network Connectivity IP Address field.
3. Select Save Changes.
