10 BUILT-IN ETHERNET FUNCTION INSTRUCTIONS
10.2 Socket Communications Function Instructions
■
Control data
*1 System: The CPU module stores the execution result of the instruction.
*2 When the instruction is executed for a connection that is not open, 0H is returned.
*3 Of the host station port numbers, 1 to 1023 (0001H to 03FFH) are generally reserved port numbers and 61440 to 65534 (F000H to
FFFEH) are used by other communication functions. Thus, using 1024 to 5548 and 5570 to 61439 (0400H to 15ACH and 15C2H to
EFFFH) as the port numbers is recommended. Do not specify 5549 to 5569 (15ADH to 15C1H) since they are used by the system.
