What Is DriveLogix? 2-15
Connections to remote ControlNet or EtherNet/IP devices
A remote device over ControlNet and EtherNet/IP can be configured as
either a rack-optimized connection and direct connection. In this example, the
DriveLogix controller uses one rack-optimized connection to communicate
with the communication adapter to receive data from the digital I/O modules
(two in this example) and uses one direct connection to communicate with the
analog module.
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
direct connection for one I/O module (slot 2)
1
1
DriveLogix controller to communication card
(1788-CNx or 1788-ENBT)
0
DriveLogix controller to communication adapter
(rack-optimized connection for digital I/O modules)
1
DriveLogix controller to remote analog I/O module 1
DriveLogix controller to host PowerFlex 700S drive 1
total connections used: 5
total connections through the
communications card:
2 – This number is within the
connection limits of either
the 1788-CNx card (maximum
connections = 9) or the
1788-ENBT card (maximum
connections = 32).
