7-22 Communicating with Devices on an ControlNet Link
Each produced tags requires one connection for the producing controller
and an additional connection for each consuming controller. Each
consumed tag requires one connection.
Example 2: Total connections required by DriveLogix1
The following table calculates the connections used in this example.
If you configured the local I/O modules as rack-optimized, you would only
need the DIN-rail connection to the I/O modules, reducing the above
example by 3 connections.
Example 3: DriveLogix
Controller to Other Devices In the following example, one DriveLogix controller communicates with a
Logix5550 controller and a ControlNet PLC-5 controller over ControlNet.
