*1 If an invalid value is written, the general status 09H (Invalid Attribute Value) is
returned.
*2 When automatic allocation is selected, the start multicast address is calculated
from the expression
"239.192.1.0+ ((IP address host section -1) & 03FFH) x 32).
(Example)
When the IP address is 192.168.0.10, the multicast address is as follows:
Start address = 239.192.1.0 + (((192.168.0.10 - 1) & 0x3FF) << 5)
= 239.192.1.0 + ((192.168.0.9 & 0x3FF) << 5)
= 239.192.1.0 + (0.0.0.9 << 5)
= 239.192.1.0 + 0.0.1.32
= 239.192.2.32
