Parameter Setting
Default
Description Necessity
Force Transmit 0 to 65535 ms 0 ms
0: Disable the force transmit timeout.
1 to 65535: Forces the NPort’s TCP/IP protocol
software to try to pack serial data received
during the specified time into the same data
frame.
This parameter defines the time interval during
which the NPort fetches the serial data from its
internal buffer. If data is incoming through the
serial port, the NPort stores the data in the
internal buffer. The NPort transmits data stored
in the buffer via TCP/IP, but only if the internal
buffer is full or if the force transmit time interval
reaches the time specified under Force Transmit
timeout.

(E.g.,

set by this parameter.
The “Destination IP address” parameter can use
either IP address or Domain Name. For some
applications, the user may need to send the data
actively to the remote destination domain name.
