Model 2C32 Dual Self-Healing Ring Module

Many industrial processes require very precise control.

Failure of communications between the various elements of
a control system may cause serious problems. Therefore,
the communication systems employed have to be robust.

Weed’s 2C31 and 2C32 Self-Healing Ring Modules

address this need by providing multiple communication
paths between the various elements of the system, and 

The EOTec 2000 ControlNet™ Fiber Optic SHR/DSHR
Communications Modules provide the highest assurance of
network performance for any ControlNet™ network. Self-
Healing Ring networks for both the Channel A and the
Channel B are supported simultaneously providing multiple
pathways for data routed to the end nodes in the system.
Network errors are communicated through advanced 
diagnostics to give the operator early indication of 

communication faults without losing any communications to
the ControlNet™ end nodes.

The Model 2C31 is intended for Single Self-Healing Ring

applications, while the Model 2C32 is designed for Dual
Self-Healing Ring systems. Weed also manufactures
modules for other ControlNet™ topologies, including copper
to fiber conversion (Point-to-Point), STAR, Daisy Chain and
Cascading Tree.

Model 2C31 Self-Healing Ring Module

utilize advanced Downstream Multicasting technology. In the
event of a failure on one communication path, communications
are still maintained along a secondary path or, in the case
of a dual ring, tertiary paths.

Downstream Multicasting transmits an incoming message

in multiple directions and insures that while directing the
message toward all nodes in the ring it is never retransmitted
