Issue Details

I notice that there is a plus sign on my software list of CompactRIO (cRIO) in NI MAX. Does it indicate anything? Will it affect my cRIO performance?


The plus sign indicates that the software is an optional add-on that is installed together with the recommended software needed to run the cRIO. You can specify which optional software that you want to install by ticking it during the add/remove software session for cRIO. Note that every time you add or remove software, the cRIO will be formatted.
