TCP Connection Drops out Time out

[rsmrostov]

Hi group!

Does anyone have an idea - how long does a TCP connection stays opened if opened with

TCP Open Connection Function?

I have an application, where I am writing something through a TCP connection - waiting for 10 seconds

-writing something again - waiting for 170 s and repeating this loop for indefinite amount of time.

Some units (not all) drop out and stop receiving the commands. Trying to reopen the TCP connection causes a run-time error (I believe 56?)  Do you think the connection is being closed on the TCP Server's end?

Check out the below about TCP connections with Error 56:
