Closing a TCP/IP Connection

Summary

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not exceed the maximum number of connections.

Idle connections that are closed automatically when the limit is reached can affect system performance.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

TCP/IP connections can be closed by the:

remote station: The remote station ends communication by sending a TCP/IP connection closure.
local station: When the maximum number of open connections is reached and a new connection is required, the connection that has been idle for the longest time is closed.
