Communicate over Networks Chapter 4
You can use these software products with a 1769 CompactLogix controller on a
ControlNet network.
The 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.
In this example:
• the controllers produce and consume tags amongst themselves.
• the controllers initiate MSG instructions that send and receive data or
configure devices.
• the personal computer uploads or downloads projects to the controllers.
• the personal computer configures devices on ControlNet, and configures
the network itself.
