Planning to Use Your ControlNet PLC-5 Processor 2-13

If an input only connection is made to the adapter:

• an exclusive owner connection can be made

• another input only connection can be made

• a listen only connection can be made

• a redundant owner connection can be made

A listen only connection can only be made to the adapter if:

• an exclusive owner connection already exists, or

• an input only connection already exists, or

• a redundant owner connection already exists

If a redundant owner connection is made to the adapter:

• an exclusive owner connection will be rejected

• an input only connection can be made

• a listen only connection can be made

• another identical redundant owner connection can be made

Multiple Processors Can Control I/O on the Same ControlNet

Link

A processor at any valid node address can control the outputs of a

particular module or rack. However, only one processor can control

the same outputs at any one time.

In the following figure, the processor at node 1 can control the

outputs of node 2 while the processor at node 3 controls the outputs of

node 4.
