Cannot connect to cFP-2120 via FTP

I am using several cFP-2120 running LV RT 8.2.1 with the FieldPoint drivers version 5.0.1. for process control and data acquisition. All data are logged to a file and broadcasted via network-shared variables. The data files can be downloaded using an external ftp client. Lately, two of our units have been giving me some trouble as I sometimes can not access the cFP2120s via ftp. I can ping the unit on the network though, all programs are still running and I can still access the network-shared variables. Only a reset of the controller seems to solve the issue.
Any pointers would be greatly appreciated.

Kyle,
Thanks again for contributing.
> Can you only connect one time after you reset and it stops working if you try to reconnect shortly there after or does it work for awhile and then eventually it stops working?
After we reset the controller it seems to always work for awhile before it stops working again.
> Are you using the controller to perform any other tcp communications with an other servers, besides the network shared variables? 
Our system is configured as a slave on a Modbus TCP network and is queried typically once a minute.
> Whats your memory usage on the cFP? Do you have the System State Publisher software loaded? Try connecting with DSM and see how much CPU and Memory usage you are using.
No, I havent done this yet. I think this was instroduced with LV8.6? I just upgraded to the latest LV version and will investigate. This will take a week though.
> Can you check the timeouts in MAX to make sure they didn't get changed? Right click on the cFP and select Communication Timeout Settings. From stock they should be 15000 ms.
The timeout in MAX is still 15000ms.
> Are these cFP dedicated to just this one task or are they reconfigured from time to time?
We only reconfigure these units when we upgrade the software. This has been less frequent lately and happens maybe once a year.
All the best,
Volker

  • Cannot connect to SGD server via proxy

    Hello
    We have a recently installed SGD server running.
    Some clients have been setup today with accounts to access it but none of them can get on at the moment. The error message presented is as follows:
    Cannot connect to the server sgd.ourdomain.co.uk:443
    The HTTP proxy "NTLM" at devicename:8080 failed to connect to the server sgd.ourdomain.co.uk:443
    The following response was returned:
    HTTP/1.1 403 Forbidden
    Clearly there's a proxy/firewall getting in the way.
    Client has tried to connect from a network that is behind a different firewall and has been sucessful.
    I'm hoping to get further details on the proxy/firewall setup but this could take a while.
    Has anyone encountered this previously and if so, can any solutions be suggested.
    Thanks,
    Rob

  • I can't connect to Windows Server via FTP

    I've been using FTP for about 13 years and it works fine on Apache servers but can't connect to a windows Server via my Fetch FTP program. The site owner sent me a screenshot and copied/pasted the password so I know I have the info correct. It is still giving me errors.
    Is there a special method to connect to Windows server via FTP?

  • Help, I cannot connect to the internet via airport with either my Imac or I-Pad.  Connecting via ethernet works okay for Imac.  I can connect wirelesssly with my windows laptop.  I have reset my router, created a new network. It was all okay on Monday

    Normally I have my IMac, I-Pad and Windows Laptop all working on my home network via wi-fi. This week I find that I cannot access the inetrnet on my IMac or I-pad via wi-fi but I can connect to the internet via wi-fi with my windows based laptop.
    The airport diagnostics (reds/yellows) indcate that I am connected
    I can access the internet if I plug my IMac into the router via an ethernet cable
    I have restarted the IMac and the I-Pad, rebooted the router and created a new network.  None of these changes has made a difference.  Does anyone have any ideas please?

  • Cannot connect to iTunes Store via iPad

    When I am outside of my home wi-fi I cannot connect to the iTunes store via the App Store on my iPad.  iPad software is current (updated this morning at home).  Rebooted iPad.  I can access the internet via Safari, get current email, run Netflix, etc. but cannot access iTunes store via the App Store.  This issue happens whenever I use a public wi-fi (hotels, airports, etc.) rather than my home wi-fi.  Any suggestions?  Thanks!

    Ok, I found a solution that worked for me when trying to connect to the iTunes store by tapping the "update" button in the "App Store" app on my iPad 2. Before the solution was implemented I'd always get the error message "cannot connect to iTunes store". Once the solution was implemented I now can connect to iTunes using the "update" button in the "App Store" app and I get the normal message "All apps are up to date". The solution is this:  go into Settings, then General, then scroll to the bottom where it says Date and Time. Tap Date and Time and then turn OFF Set Automatically. When you do that a new option will be added that says Set Date and Time. Tap it. You'll now get a drop down feature. Set the Date AHEAD 2 YEARS. The Time you can leave alone.
    Once you do that you might get a bunch of reminders and messages that your apps and stuff haven't been updated in two years. Click cancel or close on each of those messages or reminders. Now go back into Settings, General, Date and Time, and turn Set Automatically back to ON. Reboot your iPad. Open the App Store app again and go to the Update button. It might ask you to log back in to your iTunes account. It should now work. If not, close the App Store app completely and open again and try the update button. Hope this helps.

  • Cannot connect to one domain via wireless

    All of a sudden I cannot connect to my COX pop email account with my Macbook via my wireless router only, either by any email client or web access. Ethernet into the same router is ok. My Powerbook G4 is fine or my Dell PC notebook is fine either connection. I've also tried a neighbors wireless connection with the same result. So far any other of my pop 3 connections are ok. This has seemed to happen after upgrading to 10.5.1. Any ideas out there??

    In that case you should try to download and upgrtade the firmware for the router.
    This link is where you can download the firmware for the router

    Good Luck. I am using Windows 7.
    That's my problem exactly, but I can't find the: ''Uninstall Safely Feature and ReInstall''. Where is that??

  • Can no longer connect to Mac index via FTP

    The other computer on my LAN is running Ubuntu Karmic and I can FTP to it no problem. Used to be able to FTP to my Mac no problem until I tried this free firewall software which claimed to have a decent GUI. I made sure to remove the software completely using the TrashMe app when I decided it was useless, but have not been able to reconnect from my Linux machine to Mac via FTP. I can ping the Mac no problem and have also gone through all the basic troubleshooting steps: turned off the firewall and tried - nothing, turned the firewall back on - some story, restart, rebooted router, release/renew IP (not that that would help but what the hey).
    Anyone else experienced similar issues? Any suggestions as to next steps?

    Hi. Try this:
    - Open System Preferences
    - Open Sharing (not sure if is this name)
    - Activate Share Files (or file sharing...)
    - In Options button, you got to check FTP and the users (below) that will be able to access
    Voilá... hope this works for you!

  • Cannot connect to my box via XDMCP etc...

    I already have a Solaris 10 10/08 Sparc Sunblade 150 working great!!!
    I just built a brand new system AMD64 x86 box and it seems to work great as well but the one thing I cannot get working like on the Sunblade is a remote desktop session (XDMCP?)... After reading many posts on this I have enabled XDMCP which seems to do nothing, Opened up network services via the netservice command I think it's called and still nothing, seems to not work.... Since the install seems to be identical to the SPARC
    install I did... what do I need to do in X86 Solaris 10 to get it to work the same as the SPARC box???
    Thanks,
    Scott

    I am also not able to connect to my cheapo AMD Solaris 10/8 machine. The local console gdm login works fine and I can ssh into the machine. I did choose the "secure" option when I installed and have followed the advice I found on several postings in this particular forum. I ran gdmsetup to see if XDMCP was enabled and it was.
    I am trying to use vncviewer from realvnc.com to connect. Here's what I see:
    main: unable to connect to host: Connection refused (111)
    If I go "netstat -an |grep 177" on the Solaris box I see:
    *.177 Idle
    *.177 Idle
    I am curious as to whether the pf service might be an issue since it is enabled. The ipfilter service is not enabled.

  • Cannot connect 2 external monitors via port replicator using Portege Z30-16U

    Hi All
    I need hell I just moved from a other laptop to the Portege Z30-16U, I have spent hours trying to connect my 2 external monitors to my Hi-Speed Port replicator III 120W but my laptop will only see one monitor.
    I have been using 2 external monitors with my laptop for yrs as I do a lot or reading and I do not want to use only one and the laptop screen.
    I have tried VGA cables and mix of a VGA and a HDMI but nothing is working.
    Can anyone tell me how I can connect and view 2 external monitors with this laptop and port replicator, I cannot believe it is not possible it would make no sense that Toshiba would be so technilogically behind other laptop manufacturers.
    Thanks
    Liga

    Hi
    I am not familliar with the Portreplicator of Z30, but the general behaviour of the dual-displayconnector replicators is that 1 can be used.
    Not 2 simultaneously.
    I may be wrong and you should easily be able to check this - use only 1 at a time.
    First one, then the other.
    If both works when used alone, then my suspicion is right.
    Hope this helps!

  • Cannot connect to the Internet via PPPoE in Windows manually?

    In Lion there is a little triangle after the Wi-Fi name (SSID) that can connect and disconnect the Internet via PPPoE. But how to do the same thing in Windows? Is it possible?
    And there is also a bug in Mac OS --- if you choose to show the connected time, it will freeze later and the little triangle for connecting is also disappeared! So you have to refresh it to recall that little triangle again.

    I have the exact same problem and my home network have a max capacity of 250 devices, which Im not any way near off.
    I have one pc connected via ethernet, so I always have an option of connecting if WIFI fails.
    I have one iMAC connecyed via WIFI
    I have one Apple notebook conenected via WIFI
    I have one Nintendo Wii connected via WIFI
    And, I have one Apple TV which will not connect while other devices are connected. If I disconnect the notebook and iMAC the Apple TV works fine.
