A+5
: Receiver Port number
A+6
: Transmit data word size (1 to 1000)

D register = 4
Sample Program
12544 = H3100
50 = H0032
Socket number = 1
Receiver IP address = 192.0.0.5 (-16384 = HC000)
Receiver Port number = 4000
Transmit ward size = 200
Source data table is D1000 and after
When R0622 is set to ON, 200 data words D1000 to D1199 are transmitted to the destination
(IP address = 192.0.0.5, Port number = 4000). When the operation is finished, R0622 is reset
to OFF automatically.
