■Descriptions, ranges, and data types
■Applicable devices
*1 T, ST, C cannot be used.
■Control data
*1 The contents in the "Set by" column mean as follows:
User: Data to be set before the execution of the SP.SOCSND instruction
System: The CPU module stores the execution result of the SP.SOCSND instruction.
When TCP is used, specify send data length that is smaller than the maximum window size of the target
device (Receive data buffer of TCP). Data whose size exceeds the maximum window size of the target device
cannot be sent.
