2-14 What Is DriveLogix?
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)
