Default Unconnected Timeout (seconds)
When a CIP request message does not contain a protocol-specific timeout value and Maximum number of concurrent unconnected requests per TCP connection is reached, the system times the message for the number of seconds specified by this option. When the timer expires, the message is removed to make room for future requests. You can specify an integer from 0 to 360. When you specify 0, all traffic that does not have a protocol-specific timeout times out first.
Maximum number of concurrent unconnected requests per TCP connection
The number of concurrent requests that can go unanswered before the system closes the connection. You can specify an integer from 1 to 10000.
Maximum number of CIP connections per TCP connection
The maximum number of simultaneous CIP connections allowed by the system per TCP connection. You can specify an integer from 1 to 10000.
