Labview was blocked when building communication through TCP/IP

[Pierce]

I am trying to transfer data between a Labview system with Win2k and a RT system on PXI controller through TCP/IP. A problem is that when the Labview program started to build the communication to RT, the other Labview programs are all blocked. Howerver, the other application programs except Labview are running properly.

What do you mean: "...when the Labview program started to build the communication to RT", also what do you mean the other LabVIEW programs were "blocked"

Thank you Mike.

I am trying to transfer data through TCP/IP and Ethernet. The source is a Labview RT program in a PXI controller, and the receiver is a Labview 6.1 program in a workstation with Win2k, and here we focus on the program in the workstation. Besides the communication program, some other Labview programs are also running in the workstation in the mean time.

The problem occurred at the beginning of the TCP connection: during the following several seconds after the communication program started, I cannot access any of the Labview programs (no response when click on any Labview program). Meanwhile, I found that the CPU usage and memory usage were in normal level and I can access any other windows application program properly. So it seems that the communication program held up all the LabVIEW programs when it started to build connection. Do you have any idea?

Two questions:

1. Once the TCP/IP connection is open, does the response of the other LV programs return to normal?
2. How long does it take to establish the connection?
3. How are you identifying the system you are connecting to, IP address or computer name?

Hallo,

Ich benutze Diadem 9.1

ich habe zwei Computer, die ich über ein Modem über die TCP/ IP Verbindung  verbinden will.

Auf einem PC ist die Messwerteerfassung, und auf dem anderen PC ist die Messdatenauswertung.

Der Messrechner ist der Sender und der andere der Empfänger.

Wie kann ich kurzzeitig eine verbindung aufbauen und danach beenden?
