4.7.9 Fieldbus Redundancy

VACON® 3000 supports the usage of two fieldbus connections. The drive accepts control data only from the primary fieldbus. If the
primary fieldbus connection fails, the control can be automatically switched to a secondary fieldbus using the fieldbus redundancy
control. VACON® 3000 built-in fieldbus protocols support fieldbus redundancy control. The only exception is RS485 N2, which does
not support fieldbus redundancy. Recent firmware versions of fieldbus option boards also support fieldbus redundancy.
When switch on failing mode is selected, and the current fieldbus connection detects missing communication from the controller,
the switchover command is given to change to the other fieldbus connection. When switch on faulted mode is selected, and the
current fieldbus connection gets a timeout, the switchover command is given to change to the other fieldbus connection.
The switchback functionality forces a change back to the primary fieldbus connection when it is in operational state and when the
given time delay has elapsed. If the switchback functionality is deactivated, the switchover between the fieldbus connections is only
performed when the currently controlling fieldbus begins to fail or becomes faulted.
The currently controlling fieldbus protocol can be checked from the monitoring value V5.13.2 Controlling Fieldbus (ID 2610).
