[Function]
Set the storage areas of IP address/port number for the connection destination of the user-open
TCP/IP channel. The connection destination information stored in the five consecutive integer
variables, beginning with the integer variable number specified in operand 2, is defined as the
connection destination of the user-open TCP/IP channel specified in operand 1.
This command must always be executed before an OPEN command.
(Note 1)
Channel Nos. 31 through 34 can be specified in operand 1 with the Ethernet option.
(Note 2)
Executing this command while a channel or channels are already open will specify settings for the
next OPEN command.
[Example]
LET
90
192
IP address of connection destination (H) = 192
LET
91
168
IP address of connection destination (MH) = 168
LET
92
72
IP address of connection destination (ML) = 72
LET
93
101
IP address of connection destination (L) = 101
LET
94
64514
Port number of connection destination = 64514
IPCN
31
90
Declare the IP address/port number storage area for the
connection destination of channel 31 = Local integer
variable between 90 and 94.
In the above example, IP address 192.168.72.101 and
port number 64514 are set as the connection destination
of user-open TCP/IP channel No. 31.
