TCP connection monitoring time
If there is no data traffic within the connection monitoring time, the CP sends a keepalive to
the communications partner.
● Permitted range: 0 ... 65535 s
● Default setting: 180 s; if you enter 0 (zero), the function is deactivated.
The monitoring time is configured for the Ethernet interface as the default for all TCP
connections. The default value can be adapted individually for each connection in "Operation
center".
TCP keepalive monitoring time
After sending a keepalive, the CP expects a reply from the communications partner within
the keepalive monitoring time. If the CP does not receive a reply within the configured time, it
terminates the connection.
● Permitted range: 0 ... 65535 s
● Default setting: 1 s; if you enter 0 (zero), the function is deactivated.
The monitoring time is configured for the Ethernet interface as the default for all TCP
