[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.
