Default Set value and explanation
0000H [Set value] TCP or UDP communication process port number.
- Set any port number other than 0H (a value of 1025 (401H) or higher is
recommended).
0000H [Set value] Partner node IP address
When using TCP Fullpassive and Active open:
Specify an IP address for the partner node that is in the same class, and
is other than 0H or FFFFFFFFH.
When using UDP:
0000H
Use an IP address for the partner node that is in the same class, and is
other than 0H.
When using TCP Unpassive open:
No address needs to be specified.
0000H [Set value] Partner node port number
- Set any port number other than 0H (a value of 1025 (401H) or higher is
recommended).
- This is not necessary when using TCP Unpassive open.
0000H [Set value] 1 to 64
- Set the station number of the partner node when MEWTOCOL
communication is being carried out.
- Avoid duplicating the number of another station on the network.
- This is ignored if MEWTOCOL communication is not being used.
0000H [Set value] Ethernet address of partner node
- When using TCP Active open, if the partner node has no ARP function,
specify this.
Example: When 1.2.3.4.5.6 is set, the offset addresses will be:
0000H
0000H
- When "0" or "FFFFFFFFFFFFH" is specified for this value, processing
will be carried out as though the partner node has an ARP function.
0000H [Set value] Receive request data size (in byte units)
- This is specified when data is being received in transparent
communication. No receive notification is made until data equal to the
specified size has been received.
- If "FFFFH" is specified, direct reception is carried out (the receive
complete signal goes on each time a packet is received).
- Specify a size such that the receive request data size is less than or
equal to the size of the receive buffer x 2.
0000H [Set value] Transmission request data size (in byte units)
- When data is being sent using transparent communication, specify the
size of the data being sent in byte units.
- Specify a size such that the transmission request data size is less than
or equal to the size of the transmission buffer x 2.
