TCP alive check time

Setting

Factory Default

Necessity

0 to 99 min

7 min

Optional

 

 

 

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: NPort automatically closes the TCP connection if there is no TCP activity for the given time. After the connection is closed, NPort starts listening for another host’s TCP connection.

Inactivity time

Setting

Factory Default

Necessity

0 to 65535 ms

0 ms

Optional

 

 

 

0 ms: TCP connection is not closed due to an idle serial line.

0-65535 ms: NPort automatically closes the TCP connection if there is no serial data activity for the given time. After the connection is closed, NPort starts listening for another host’s TCP connection.

This parameter defines the maintenances status as Closed or Listen on the TCP connection. The connection is closed if there is no incoming or outgoing data through the serial port during the specific Inactivity time.

If the value of inactivity time is set to 0, the current TCP connection is maintained until there is connection close request. Although inactivity time is disabled, the NPort will check the connection status between the NPort and remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packet, it assumes that the connection was closed down unintentionally. NPort will then force the existing TCP connection to close.

At least, the Inactivity time should be set larger than that of Force Transmit timeout. To prevent the unintended loss of data due to the session disconnected, it is highly recommended that this value is set large enough so that the intended data transfer is completed.

Max Connection

Setting

Factory Default

Necessity

1, 2, 3, 4

1

Required

Max Connection is usually used when the user needs to receive data from different hosts simultaneously. The factory default only allows 1 connection at a time.

Max. Connection 1:

NPort only allows 1 host to open the TCP connection to the specific serial port.

Max Connection 2 to 4:

Allows 2 to 4 host’s TCP connection request to open the specific NPort serial port, at the same time. When multiple hosts establish a TCP connection to the specific serial port at the same time, NPort will duplicate the serial data and transmit to all of the hosts. Ethernet data is sent on a first-in-first-out basis to the serial port when data comes into NPort from the Ethernet interface.
