User: The data must be set before executing the SP.SOCOPEN instruction.
System: The CPU module stores the execution result of the SP.SOCOPEN instruction.
*2 For the Unpassive open, the IP address and port number of the target device are ignored.
*3 Because host station port numbers, 1 to 1023 (0001H to 03FFH), are assigned for reserved port numbers and 61440 to 65534 (F000H
to FFFEH) are used for other communication functions, using 1024 to 5548, 5570 to 61439 (0400H to 15ACH, 15C2H to EFFFH) is
recommended. Do not specify 5549 to 5569 (15ADH to 15C1H) because these ports are used by the system.
