Reconfigure a Module Online
Use Ladder Logic to 
Reconfigure an I/O Module
If an I/O module supports reconfiguration, you can reconfigure the module via 
one of the following:
• Studio 5000 Logix Designer® application
• An MSG instruction in program logic
Reconfigure a Module Via Studio 5000 Logix Designer Application
To reconfigure a module, perform this procedure.
1. In the Logix Designer application, right-click a module in the I/O 
Configuration tree and choose Properties.
The Module Properties dialog box appears.
IMPORTANT
Consider these guidelines in SIL 2 applications:
• We recommend configuring SIL 2 safety applications offline. Even 
if the Logix controller and RSLogix 5000® software permit online 
SIL 2 configuration (that is, module interface option changes, 
import of the Add-On Instructions, and so forth.) a download to 
the processor is required. 
• Enabling SIL 2 on spare modules while online is not supported.
• Where a module is used without SIL 2 enabled and SIL 2 is then 
enabled for that module, a power cycle of the rack is required to 
force the new configuration to the module. The same is true 
where a module is used with SIL 2 enabled, and SIL 2 is then 
disabled for that module.
• A programming terminal is not normally connected.
ATTENTION: Use care when changing the configuration of an I/O 
module. You could inadvertently cause the I/O module to operate 
incorrectly.
