D.5 Diagnostics

The redundant system will perform many diagnostic checks to verify the health and

connectivity of the system.

Figure D-7. Redundancy Status (Diagnostics>Advanced>Redundancy Status)

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.
