Missing scaling box for "all" outputs

I setup MAX and scaled all my outputs and everything has been working fine for months.  Yesterday I added another fieldpoint module, set it up, and the program was running normally.  I stopped the program, changed my sample, started the program again...and suddenly my program was returning very weird (non-physical) data.  I traced it back to improper scaling (MAX was reporting correct raw values), but when I tried to fix the problem, I no longer have access to the settings box I used to do the initial scaling!  (see attached image)

 

I was able to workaround this problem by polling each channel individually (with a loss in latency now from polling the serial module an extra 5 times...) but I'm really curious as to how/why this occurred.  Any ideas?

 

Thanks,

Randall

Hi Mechanical-Randall,

 

Have you tried removing your configuration in the Data Neighborhood and adding your devices again?  You can do this by right-clicking your FieldPoint 1000 and selecing Find Devices.  Let me know if the selection box appears after doing this.  Make sure to keep a backup copy of your *.iak file just in case you need to restore it.
