What Is DriveLogix? 2-13

Connections for remote devices

To optimize the number of available connections, place remote, digital I/O in

the same location and use a rack-optimized connection to the remote adapter

that connects the remote I/O to the DriveLogix system.

If you have remote analog I/O modules, or want a direct connection to

specific remote I/O modules, you do not have to create the rack-optimized

connection to the remote adapter. To use direct connections to remote I/O,

select “none” for the communication format of the remote communication

device.

Direct connections for I/O modules

In this example, assume that each I/O module is configured for a direct

connection to the controller.

The following table calculates the connections in this example.

IMPORTANT

It is vital that you manage your connections to remote

devices because, while the DriveLogix controller allows up

to 250 total connections, the communications cards that

connect to remote devices are limited to far fewer

connections (i.e. 32 connections for ControlNet or

EtherNet/IP).

Connection: Amount:

DriveLogix controller to 3 local I/O modules
