Redundancy configuration restrictions

C300 Controller Device Index

Backup or Secondary — Refers to the controller in some state of readiness to assume
•
the responsibilities of the Primary.
Redundancy configuration restrictions
There are a number of restrictions imposed to device configuration for the purpose of
providing device redundancy.
C300 Controller Device Index
The primary C300 Controller of a redundant controller pair and non-redundant C300
Controllers must be configured with an odd numbered Device Index. Control Builder
will enforce this restriction. The secondary C300 Controller of a redundant controller
pair is assigned an even Device Index (primary controller Device Index plus 1) upon the
configuration of the primary controller.
The Device Index switches on the primary and secondary controller IOTAs must be set
according to their configured Device Indexes. If the Device Index switches on a primary
or non-redundant C300 IOTA are set to an even number address or do not match the
configured Device Index, then an error is generated when loading the controller and the
load operation is aborted.

IOLINK interface considerations

In a C300 redundant controller pair, a C300 IOLINK function block which is configured
to support a specific IO Family, (IOLTYPE parameter set to PM_IO_TYPE or
SERIES_C_IO_TYPE) is verified in the secondary controller by the primary controller.
After the primary controller synchronizes the configured IOTYPE, the primary uses the
IOLink interface to communicate with the secondary controller to verify that the
associated IOLink interface on the secondary is configured to support the same IO
Family. If the IOLink cables are not connected between the primary and secondary
controllers, initial-sync failures will result.

Series C FIM restrictions

The Series C FIM control hardware is available with a non-redundant IOTA that accepts
a single Series C FIM module and a redundant IOTA that contains connections for
accepting two Series C FIM modules.
Non-redundant IOTA
A non-redundant Series C FIM module can be configured with either an odd or even
Device Index. The Device Index switches on the associated non-redundant IOTA must
be set according to the module's configured Device Index. A Series C FIM module
