 Remote Node Programming
In this example, programming is also required in the remote node. The order of sending and receiv-
ing is reversed in comparison with the above procedure.
1
The SktUDPCreate instruction is used to request creating a UDP socket.
2
The SktUDPRcv instruction is executed to request reception. The receive data is stored in
RcvSocketDat[].
3
Execute the SktUDPSend instruction to request sending. The data in SendSocketDat[] is sent.
4
The SktClose instruction is executed to close the socket.
