I was unable to connect my ni crio 9022 and the error occured is " failed to connect to real time target" when i tried to connect it in  a project and also  it is appearing well in the MAX with the assigned IP address but there it is indicating that no software installed but when i tried to load the software it is there in the target .

status led in the crio in blinking twice per second

Is this because of any software loading problem , do i have to uninstall and install the software again?

I'd turn on the console out, and watch for clues during boot.

If that goes nowhere, reformat flash, and reinstall standard software + addons.

Why not read the manual to find out what the flashing status LED means ? Here is what it says:

"The controller has detected an error in its software. This usually occurs
when an attempt to upgrade the software is interrupted. Reinstall
software on the controller. Refer to the Measurement & Automation
Explorer Help for information about installing software on the
controller."
