TCP/IP connection lost after connection

Hello,

I am including a dll file for a digital I/O module. The DLL file works perfectly under VB.NET and C #.
But under LabView I have problems.
The TCP/IP connection does not stay upright, that means. it breaks as soon as a connection is established.
The DLL file also has an integrated KeepAlive function, but this is not influenced by the outside.

Who can help me to solve the problem?

thank you in advance
Natalie

Hi Natalie1984,

 

What do you mean by it breaks as soon as a connection is established?

Does your code works at least once? - Do you send actual data through "SEND_STATUS_32" Method?

Do you get any error? 

 

Can you try any other dll in LabVIEW, if it works correctly?


Regards,

Patrik
