Another Dead NI4000

vining

In less than 24 hours I've manage to kill two NI4000. Las t night uploaded a program that has been working fine for days after making several simple changes like changing device buffer sizes, download and then dead. Input/Ouput leds on solid. Dip switch 1 no joy, I can ping but not telnet, no IP and no serial.

This morning I swapped the bad with a recently repaired NI4000 (my old work bench master) which I admittingly killed by FTPing in places I shouldn't have, downloaded the program and all was well again.

After several download during the day with out a hitch I downloaded another which again had no significant modifications and once again the master died exactly the same as before.

My undrstanding of Netlinxs it that regardless of what you write in code (unless your code is modifying the system files or structure) the written program can't kill the masters. Maybe end up in a infinite loop but not corrupt the flash image.

Right now I'm too bummed and too tired to smash them to pieces but boy would I like to. An of course now I'm out of replacement masters w/ enough serial ports for my needs. I do have a NI700 & NI2100 available to allow me to work on programs but I'm really not in the mood to do a partial swap out and reconfig.

Are you able to telnet in to the unit? If so, you could do a CLEANDISK and reboot. (I just had to do that a few mins ago ) Also, check your free mem (SHOW MEM). If all that fails, there is a dipswitch on the unit that tells it to ignore the program on reboot so you can get in and do a cleandisk.

Hope one of these helps.

NI-4000 overwitting System files

I was ftping camera still shots into a file and accidentally killed the 4000. I thought the camera was writing to the same file, but no! it was creating a new file every second - and with 6 six hour the NI-4000 was dead in the water! Need a new flash card to sort out the problem. But AMX Australia helped out straight any with a new flash......

Hmm, a bit of bad file management on AMX's part. It should just run out of space and refuse it, not overwrite system files ...

Now, I've had processors lock up due to running out of memory, but "clean doc," or deleting the files with FTP always fixed it; I never needed a new flash.
