Parameters

The UDP socket number to be opened specified as 2 bytes between 1 and 8. 

The area in which the results of the command execution are stored. The first byte
specifies the memory area and data type (variable type). The 2nd to 4th bytes
specify the beginning address of the results storage area. Refer to page 192 for
details about the variable types and addresses that can be specified.

The UDP port number for communications with the socket is specified as 2 bytes
(0 cannot be specified). Packets received at this port are distributed to the socket
specified in the UDP socket number, and send packets are distributed from the
UDP socket to this port. The port number specified as the FINS UDP port num-
ber (default value 9600) cannot be used.
