Rockwell Automation 5730 DriveLogix5730 Controller for PowerFlex 700S Drives with Phase II Control - Manual (Page 135)

Communicating with Devices on an EtherNet/IP Link 6-31
Example 1: DriveLogix5730
Controller and
Distributed I/O In the following example, one DriveLogix5730 controller controls
distributed I/O through a 1794-AENT module.
Controlling Distributed I/O
This example has DriveLogix1 controlling the I/O connected to the remote
1794-AENT module. The data the DriveLogix5730 controller receives from
the distributed I/O modules depends on how you configure the I/O modules.
You can configure each module as a direct connection or as rack optimized.
One chassis can have a combination of some modules configured as a direct
connection and others as rack optimized.
All analog modules require direct connections. Diagnostic modules support
rack-optimized connections, but require direct connections to take full
advantage of their diagnostic features.
Total Connections Required by DriveLogix1
The following table calculates the connections used in this example.
If you configured the distributed I/O modules as rack-optimized, you would
only need a rack-optimized connection to the 1794-AENT, reducing the
above example by 3 connections.
Connection: Amount:
DriveLogix1 to 4 distributed I/O modules (through 1794-AENT)
all I/O modules configured as direct connection
no connection to the 1794-AENT 4
total connections used: 4
