Communicating with Devices on a ControlNet Link 7-23

Example 1: Controlling remote devices

This example has DriveLogix1 controlling the I/O connected to the remote

1794-ACN15 module. The data the DriveLogix controller receives from the

remote I/O modules depends on how you configure the remote 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.

Example 1: Total connections required by DriveLogix1

The following table calculates the connections used in this example.

If you configured the remote I/O modules as rack-optimized, you would only

need a rack-optimized connection to the 1794-ACNR15, reducing the above

example by 3 connections.

Connection: Amount:

DriveLogix1 controller to 3 local I/O modules

rack-optimized connection for the DIN rail

direct connection for each I/O module

DriveLogix1 controller to remote 1794-ACNR15 1

DriveLogix1 to 4 remote I/O modules (through

1794-ACNR15)

all I/O modules configured as direct connection

no connection to the 1794-ACNR15

total connections used: 9
