Redundant Controller Configuration (ControlNet Supervisory Network)
The above example illustrates a
Redundant Controller
configuration. The redundant
Controller
chassis
are
identical
, with all modules in the same slot locations and no I/O modules in the Controller
chassis.
Up to
four
(4) I/O
CNIs
are present in each Controller chassis,
each
of which can
support up to 24
IOMs
(maximum of 64 IOMs per Controller). All four I/O CNIs may share a single ControlNet trunk cable,
or individual cables may be used per CNI as needed. As an example, a controller with 3 I/O CNIs could
use a single I/O ControlNet cable, two I/O ControlNet cables or three individual cables. All three
configurations are valid.
All CNIs on the same physical
Supervisory
or
I/O ControlNet
network must be either single-cable type
or redundant-cable type, but each must not contain a mixture of both. This is a requirement for proper
ControlNet cable fault handling and for normal ControlNet operation with minimal communications errors.
The PC ControlNet Communication Interface is only available in the redundant configuration, but works
properly in either configuration.
CNI cards in a redundant chassis are either Tx-CCN012/013 (non-redundant media) or Tx-CCR012/013
(redundant media) ControlNet Interface (CNI) modules. The CNI cards in the primary rack have the same
model number and revision as the CNI card in the same slot of the secondary rack.
