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.
