how to work in different sequences...

[alan4]

Error occurred at close file in "Program Name Here.VI"

Possible Reason(s):

LabVIEW: An input parameter is invalid.
---
NI-488: Command requires GPIB controller to be in charge.

Does anyone have any clue as to what this message is trying to tell me?

Its trying to say that an input parameter is invalid, ignore the text after that.

Post your code please, cant find Program Name Here.VI in the previous vi you posted.

[alan4]

here you have i am using labview 2009!!

[.aCe.]

I still cant find that vi. I am possibly missing a toolkit or something.

[alan4]

apart from that have you got an easy example of tcp ip?

[.aCe.]

I am guessing you have tried the examples that ship with LabVIEW?

The following links may be of help.

Client

Server

Also, a search yields a lot of results: http://search.ni.com/nisearch/app/main/p/bot/no/ap/global/lang/en/pg/1/ps/30/q/client%20server%20tcp...

Hope this helps.

There are a couple of problems with your attempt, but you're moving in the right direction. 🙂

The producer (servidor) generates ALOT of messages, you'd do well to slow it down with a wait. (e.g. 1000ms)

The Client expects 2 parts of a message, [Message length], and [Message]. You never generate or send a message length, only the [Message].

The sender-loop has a 0 ms timeout, and you only send once it timeouts, which it wont do due to #1. (That's probably the memory issue)

I'd recommend a longer timeout, if any (-1 will only execute if there's a message, else it'll wait) and always send with message recieved.´

Run the code in Highlight mode and you'll see where the problem starts in a better way.
