All rights reserved. Thanks for pointers to docs, or other insights. I am trying to establish a simple TCP/IP connection with local host itself. Error 64 (Not Connected) - where could that happen?
That is not how TCP/IP works. In the past some hubs with auto detection/negotiation of the speed and/or crossover or not connection, did have troubles to properly detect certain network cards resulting in a carrier on the A new labview.ini file was created. When the TCP/IP Listen hears another computer trying to connect over the correct port, it establishes a Connection ID, and an Error Signal, and those outputs are used in later TCP/IP https://forums.ni.com/t5/LabVIEW/TCP-Error-Codes-62-66/td-p/2095932

Also, I am not saving any of the data that I am receiving. Labview Error 62 Thanks for your time..!!! See, for example, "Error 62 and Error 66 in the TCP Examples under Windows NT," "The NT OS will return error 62 or 66, depending on the state of the TCP It seems the problem is hardware. (Geez I love saying that!) The reset does not necessarily close/destroy the network connection and in the meantime it continues to report the "56".
Feel free to email me if you have questions.

I think you can access the lower layers of the IP stack to enable/disable Keep alive packets as well as setting the period of the Keep alive packets. Any help is greatly appreciated.Thanks 0 Kudos Message 1 of 10 (3,019 Views) Reply 0 Kudos Re: TCP error 66 Anonymous Active Participant 02-22-2004 03:37 PM Options Mark as New Bookmark Sign In Sign Up Browse Back Browse Forums Downloads Gallery Staff Online Users Activity Back Activity All Activity My Activity Streams Unread Content Content I Started Search Developer Resources Partners This is the diagram of a sub-vi we have developed that will receive a string send from a remote computer.

Several functions may not work.
none of this gets me going... Labview Launches but VIPM seems to time out before Labview is fully up. From the reason analysis, I think it might be the reason in VI server setting, but I could not figure out why. Labview Error Code 62 Here are the some general comments on using TCP/IP.
Apart from the VI I am using only 'TCP Open Connection' function. This is why it is often good to have some form of keep-alive built into your app, a packet that is sent from both sides at regular intervals. For example http://technet.microsoft.com/en-us/library/cc957018.aspx This is one of those cases where LV described the behavior using industry standard terms, which is sometimes a "damned if you do, damned if you don't" situation... Either end of a connection can close the connection, so you could get error 66 if the remote side closes the connection cleanly even if your code has not yet done
Do I need to change any network config of my PC? Share this post Link to post Share on other sites san26141 0 Active Members 0 13 posts Posted January 19, 2007 What error, if any, does it return? For the local stack the connection is still in an active state although all packet sends and requests timeout, and that is what you get, error 56 timeout. I have tried adding "localhost" and "127.0.0.1" to the machine access list.
I am at a loss now as to what the fix is.. Any other type of operation might also return this error—for example, setsockopt setting SO_KEEPALIVE if the connection has been reset." 0 Kudos Message 3 of 6 (6,035 Views) Reply 0 Kudos Regards,H TCPClient.vi 11 KB ClientVi 112 KB 0 Kudos Message 9 of 10 (1,920 Views) Reply 0 Kudos Re: TCP error 66 Mathan Trusted Enthusiast 11-17-2009 11:16 AM Options Mark as A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied.
But I checked the time out with 100s and 180 sec. The length of the string is a number, and that number must be converted to a string. Most likely there is some info as to how long a data connection can stay open inactive before the device will close it from its own side, which is in fact I think there is some configurable timeout clearing for the TCP/IP stack, where the connection is put into the FIN state automatically after a certain amount of packet requests timeout continously.
OK, I plan to close my end on any error 62, 63, 64, 66. I am also receiving an error, "Error 66 occurred at TCP Read". The first string you receive has the data for the string length of the string you want. However, without determinism it is not possible to specify which communication error will occur first.
