Issue Details

I locked the IP configuration on my CompactRIO or myRIO in Measurement & Automation Explorer (MAX) and forgot the password. How do I reset it?

I cannot add or remove software from my cRIO or myRIO because it is password protected and I do not know the password

Solution

The method for resetting your password is different depending on whether you have a Linux target or not. Please read the relevant sections below. 
 
1. Non-Linux Real-Time Targets:
 
First, check what version of LabVIEW Real-Time you have installed and check what operating system your real-time target runs. Then, follow the steps below for the associated versions.
 
For LabVIEW Real-Time 2009 and older: 
 
Note: The password will be removed during this process. The IP configuration will need to be reconfigured. 
 
If your CompactRIO has a physical DIP switches, follow these instructions: 
Set the IP RESET switch to ON.
Reboot the controller.
Set the switch to OFF.
 
If your CompactRIO does not have DIP switches, follow these instructions:
 
Hold the RESET button until the STATUS LED turns solid orange or yellow.
Release the RESET button and the controller will restart. The STATUS LED will blink three times indicating the controller is in Safe Mode.
Hold the RESET button again until the STATUS LED turns solid orange or yellow.
Release the RESET button and the controller will reset the password, reset the IP configuration, and restart in Safe Mode.
Find the CompactRIO in MAX and restart the controller into Normal Mode.
 
For LabVIEW Real-Time 2010 and newer: 
 
Note: After this process, the CompactRIO will be usable without a password, but all files that were on the CompactRIO will be lost in the process. 
 
The security settings of the CompactRIO now carry through an IP reset. The CompactRIO controller will have to be reformatted in order to clear the password. 
Reboot the controller into Safe Mode, by using the DIP switches or holding the RESET button as described above.
Reformat the controller in MAX.
 
 
2. Linux Real-Time targets: 
 
Our Technical Support Engineering department will be able to assist customers who need to reset passwords on Linux Real-Time targets. To get in touch with an Technical Support Engineer, navigate to ni.com/support to open a service request.
 
Note: All myRIO systems run Linux Real-Time.
