NI network problem

Hi everyone,
I have some Netlinx controllers (7 NI-2000 and an NI-700) connected on an NXA-ENET24 AMX switch. I have also connected an ISDN Router on this ENET24 for having access from my office. Everything is fine except for one
NI-2000 - the main one - that is not accessable from my office. I have connectivity with this controller only when I am on the project area. The network settings are exact the same for all controllers. There is no IP conflict.
Do you have any idea for this?

George

    I had this exact issue, and this is the routine I went through to fix it. It will have to be done on site.

    1) Connect to the NI via RS-232. Reset network to dynamic DHCP, save and reboot.

    2) Re-connect, and click Get IP and Get DNS buttons. Then change back to your static IP, and only edit the IP field. Save and reboot.

    That did it for me. I can only surmise there are some hidden settings that get adjusted only in DHCP mode. I can't imagine what, or why they should be so. I wound up with exactly the same data in all the fields, but it would absolutely not work unless I got the IP dynamically once, then changed to static.

    Just back in from a job site with the exact same problem. I would like the ability to defeat the network connection while I do all my tweaking and then turn it on when I'm ready to assign the IP or the IP is hooked up. This would speed up the reboot time.

    WOuldnt you then have to load everything VIA RS-232 instead of Ethernet then? I can imagine sending a Modero Touchscreen through a Controller via RS-232...

    I always set IP's as Static. Boot up takes much less time whenthe cotnroller doesnt have to look for a DHCP Server. Even systems that I have not hooked into a Network get a dummy IP just for this reason.

    I have a router on my desk that I preload everything from panels to the controller. I assign a static IP to each piece but have on occasion (like today) have issues like the plate hooked to the wrong sub-network. The unit then takes a considerable time to reboot.

    No, I only meant to connect via RS-232 to change the settings around. Once you get it working, you use TCP. You don't have to do the RS-232 thing at all if you have a way of determining the IP assigned dynamically.

    I've tried several times to send the Modero TP file via the 'program' port and always got a error at 95% completion. Not sure why.

    Are you connecting via a virtual NetLinx or an actual? I have no idea if they addressed this since I had the problem, but I found early in the game that if you load a panel via an actual NetLinx that has multiple ports for that panel assigned, it will send the panel into a reboot cycle when it doesn't find the ports.

    For example, my NetLinx code had 4 ports assigned to a particular panel. I absolutely could not load the panel file, because it kept rebooting - the stock panel only has one port assigned. I had to reload the NetLinx with a blank program, then I could load my panel files. Once the panel had the proper ports referenced, I could put my working code back in.

    Like I said, I have no idea if subsequent firmware releases have fixed this, it was at least a year or two ago I noticed it, and now I load my panels from a "blank" master beforehand almost exclusively, so I wouldn't know it it still exists - I have sidestepped the circumstances that caused it.

    Dave,
    I have already connected the NI via RS232 and reset network to dynamic DHCP. I changed then back to my static IP but nothing happened...

    Hi George
    What port are you on the switch? Have you tried to swap ports? I had a NI-3000 last week that I had to try several times before it would take the IP info and retain it.

    I have also experienced some issues with various switch types, though not with NetLinx masters. I have had some Modero panels refuse to connect via a Linksys that had auto-rate adjustment; I've since replaced all the Linsys switches with Netgear.

    i know this is an old thread, just found it though.

    i generally HAVE to set all netlinx devices to 10MB. i've always found trouble brews if you set devices for AutoRate or 100MB. on various switches/hub networks.

    across the whole range of products, i think netlinx have a fundemental networking flaw. don't ask me to pin it down, it's not my job.

    the NI-700 would appear to have a new/different chipset (it's slower, but maybe more accurate) than other netlinx devices i've worked with.

    i've not had a problem setting ip numbers / network rebooting with controllers otherwise. haven't had to do the DHCP trick mentioned earlier.

    but i know for sure that 100MB or AUTO is just asking for trouble. i hope one day we can move beyond it.

    don't know if any of that helps, hope it does.
