This is valid as long as the network (subnetwork) mask field is
anything other than 0.
If the default router (gateway) IP address has been set,
communication will be carried out through the default router
(gateway) without an error occurring even f the class, network
address, or subnetwork address of the partner node differ from
192.168.1.1
those of the source node.
The network (subnetwork) address for the default router
(gateway) IP address must be identical to the network
(subnetwork) address for the source node IP address. If they are
different, an error will occur.
・0000 0000 H and FFFF FFFF H is regarded as an error.
Setting range: 0001 - FFFF: (by 100 ms)
With TCP, this specifies the time that a packet exists when data
transmission, etc. is carried out. "TCP ULP" should be specified
5
at an integral multiplication of "TCP re-transmission timer value".
When an integral multiplication cannot be given, round up the
given decimal number.
Setting range: 0001 - FFFF: (by 100 ms)
With TCP, this specifies the time until the receive window size
5
check packet is re-sent when the receive window size of the
other node becomes 0.
Setting range: 0001 - FFFF: (by 100 ms)
With TCP, this specifies the time until data is re-sent if ACK is
5
not sent by the other node, when data transmission, etc. is
carried out.
Setting range: 0001 - FFFF: (by 100 ms)
This specifies the time waited until open processing is carried
20
out when the same port is being re-opened, when TCP close
processing is done by the source node.
Setting range: 0001 - FFFF: (by 100 ms)
3
This specifies the time waited for the next portion of data when
data split by the IP is being received.
Setting range: 0001 - FFFF: (by 1 ms)
When divided TCP segments are received, specify the time for
20
monitoring the arrival of the following segment.
TCP reception is regarded as completed if no data are received
after the time as specified above has passed.
