TCP read error "the network is too busy", when try to use more than 1 tcp read in a while loop.

[cguan]

Hi, Guys,

I am trying to use tcp read to receive data from different tcp write commands, but when I use more than one tcp read(with the same connection ID), I got "network is too busy" error and program stopped.  How do I tell the difference which tcp write I am receiving?

For example:

I have two tcp write: 

tcp_write1 sending "tcp write 1", I am expecting tcp_read receve "tcp read 1" and dispaly in string1

tcp_write2 sending "tcp write 2", I am expecting tcp_read receve "tcp read 2" and dispaly in string2

How do I do that?

Thanks

Hi cguan,

I don't know of any easy to do that with TCP read/writes. However NI System Engineering has a reference library called Simple TCP/IP Messages that does what you want. Here is a link

LabVIEW Simple Messaging Reference Library (STM)

Please let me know how this works out.
