TCP Open Connection and Error 63

[JFMoynihan]

I am using TCP Open Connection to talk to a Yokogawa Darwin, I have now been able to trap the remote port of the device, however, I continue to get Error 63. What are some of the reasons why I would continue to get this error eventhough I am supplying all of the required information?

Do you get the error every time you try to do the open? If yes, are you sure that the IP of the instrument is set correctly? Is the instrument on the same sub-net as your computer? If not,, you should make it so. Also, if you haven't connected the instrument to its own network card, you may be having a conflict with another computer on the network.

One last thing, the way I've connected to instruments with an ethernet port is to use VISA. Recent versions support TCP/IP and that way I've been able to use MAX to debug communications with the instrument and use the VISA instrument driver with no modifications.

The IP address and subnet are correct. I have tried connecting with my computer and the device isolated from the network, but with the same result. I set up an ethernet connection in MAX. When I test the connection it fails. When I use Yokogawa software to contact the device, communication is fine. Any more hints?

Do have any more information about what the error means? Do you get an error description with this? Are you getting error 63 with the TCP Open Connection VI?

[JFMoynihan]

To the best of my knowledge error 63 is a failure to make a connection error, and it does occur in the TCP Open Connection.vi
