These diagnostics can also be mapped to Modbus registers or OPC tags. The following 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.
Table 5-1. Redundancy Diagnostics
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.
