network address (broadcast communications).
If any number other than those described above is set, a destination IP address error (error code: 423
occurs. ( Page 161, Section 9.5)
Ex.
When the IP address is 192.168.3.1:
● To perform broadcast communications, use the same network address and port number for all the external devices to
