Chapter 3 Replacement Considerations with CompactLogix and Compact GuardLogix Systems
Use I/O Modules in
CompactLogix Systems
You can use local and remote I/O modules with the controllers.
The following is information about how you can use I/O modules in
different applications.
5370 Application 5380 Application
Local I/O modules 1769 Compact I/O modules across up to
three banks
Compact 5000 I/O modules in one bank
Number of local I/O
modules supported,

(1) When you use this controller with the Logix Designer application, version 29.00.00, the application limits the number of local
I/O modules in the project to 16. For more information, see the Rockwell Automation® Knowledgebase article #942580, ‘5380
CompactLogix controllers limited to 16 local 5069 modules in V29 of Studio 5000®.’ The document is available at http://
www.rockwellautomation.com/knowledgebase.
With the Logix Designer application, version 30.00.00 or later, the controller supports as many as 31 local I/O modules.
Installation location of
local I/O modules
Across as many as three banks, the bank
containing the controller and two
expansion banks
Same bank as the controller
Installation orientation
of local I/O modules
• I/O modules are only installed in the
local bank - Horizontal only
• I/O modules are installed in multiple
banks - Horizontal or vertical
Horizontal only
Spacing on all sides of
system, min
For more information
see, Controller Spacing
on page 51
50 mm (2 in.) of space on all sides Varies based on the
operating temperature:
• 50.80 mm (2.00 in.) at 55 °C (131 °F)
• 101.66 mm (4.00 in.) at 60 °C (140 °F)
Remote I/O modules Accessible over the following:
• EtherNet/IP network
• DeviceNet network via 1769-SDN
adapter
The controllers cannot access Compact
5000 I/O.
Accessible over an EtherNet/IP network
For optimal CompactLogix 5380 control
system performance, we recommend that
you use Compact 5000 I/O modules as the
remote I/O modules.
Special considerations • Consider the number and type of
1769 Compact I/O modules in a system
when you set the requested packet
interval (RPI) rate
• Track collective system power use by
the local I/O modules
• Consider the power supply distance
rating when you plan the slot location
for local I/O modules
Track collective SA power use by the local
I/O modules in a system
