Understand and configure failover

Failover in AVEVA adapters refers to the ability of a system to automatically switch from one adapter to another when the primary adapter fails or becomes unavailable. This ensures that data collection and transmission continue without interruption, maintaining system reliability and uptime. If one adapter stops working, failover ensures another one steps in to keep the data flowing.

The Structured Data Files adapter supports client-level failover only.

Client-level failover means the adapter itself monitors its connection to the database and switches to a backup if the primary fails. This allows the adapter to keep collecting and sending data without needing help from the server or manual intervention.
