Rack-optimized connections for I/O modules

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

rack-optimized connection to the controller.

The following table calculates the connections in this example.

Combining direct and rack-optimized connections

A DIN rail can have both a rack-optimized connection and direct connections.

Assume that the I/O modules in slot 0 and slot 1 on the local rail are

configured for a rack-optimized connection and that the I/O module in slot 2

is configured for a direct connection.

The following table calculates the connections in this example.

Connection: Amount:

DriveLogix controller to 3 local I/O modules

rack-optimized connection for the DIN rail 1

DriveLogix controller to host PowerFlex 700S drive 1

total connections used: 2

TIP

The rack-optimized connection conserves

connections and lowers controller overhead in the

I/O update task. However, the rack-optimized

connection also limits the status and diagnostic

information that is available from the I/O modules

and is limited to a single RPI.

Connection: Amount:

DriveLogix controller to 3 local I/O modules

rack-optimized connection for the DIN rail

direct connection for one I/O module (slot 2)

DriveLogix controller to host PowerFlex 700S drive 1

total connections used: 3
