26 Communicate over Networks
Required Software for ControlNet Communication
The 1756-CNB and 1756-CNBR ControlNet communication modules:
• support messaging, produced/consumed tags and distributed
I/O.
• share a common application layer with DeviceNet and
EtherNet/IP networks.
• require no routing tables.
• support the use of coax and fiber repeaters for isolation and
increased distance
• support redundant media (1756-CNBR module only)
In this example:
• the controllers produce and consume tags.
• the controllers initiate MSG instructions that send and receive
data or configure devices.
• the personal computer uploads and downloads projects to the
controllers.
• the personal computer configures devices on a ControlNet
network, and it can configure the network itself.
