Parameters
TCP Socket Number (Command): Specify the TCP socket number to be
opened as two bytes between 1 and 4.
Results Storage Area (Command): The words 0 to 255 and 256 to 511 of the
memory area, words 0 to 6143 of the data memory, and words 0 to 6143 (each
bank) of the expansion data memory can be used. However, do not designate
the special auxiliary area. Refer to 11-1-4 Memory Area Designations. When a
bank that does not have expansion data memory is designated, the Results
Storage Area Error Flag will turn ON.
Local TCP Port Number (Command): The TCP port number for communica-
tions with the socket is specified as two bytes.
Timeout Value (Command): The maximum control time between receiving the
open request and storing the result. If this set time limit is exceeded, the code for
a timeout error (0080) will be set as the results storage response code. The
value is set in units of 0.1 s. The timeout time is unlimited if the value is set to 0.
Remote IP Address (Command, Results Storage Area): Specify the remote
node’s IP address. If all zeroes are set, no remote node is specified and connec-
tion is awaited from any node. If any other value is set, connection is awaited
from the specified remote node. The IP address of the connected remote node
will be stored in the results storage area.
