8.2 Socket Communications Instructions
■
Control data
Processing details
In UDP/IP communications, this instruction changes the communication target IP address and port number of the connection
specified by (s1).
• Using the SP.SOCCSET instruction allows the user to change the communication destination without
closing the connection.
• If the SP.SOCCSET instruction is executed while there is data in the receive data area, the instruction is
validated after the SP.SOCRCV or S.SOCRCVS dedicated instruction is executed. If the SP.SOCCSET
instruction is executed while there is no data in the receive data area, the instruction is validated soon after
it is executed.
Precautions
Do not use the SP.SOCCSET instruction to change the communication destination during execution of the SP.SOCSND
instruction.
Operation error
When completed with an error, an error code is stored in the completion status (s2)+1.
For the error code stored in the completion status (s2)+1, refer to the following.
