hi, I am trying to apply the tcpudp.pro example project I found on this project to send and receive tcp or udp data from a Codesys simulation of a peice of structured-text code to a C# tcp server or udp server(I will choose between TCP and UDP later, now I just want to get something working).

I am having no luck with the example, is there a trick to making this work?

I have tried adding a cyclica task with UDPProducer, and I am guessing I shoudl be setting diSOcket=0 to make the code run UdPOpenSendSocket(iPort)?

I have set up a UDP server on my computer on port 5000 run the following code, but diSendSocket =0 continously:

PROGRAM UDPProducer
VAR
diSendSocket : DINT :=0;
iPort : INT:=5000;
stDestIPAddress : STRING := '127.0.0.1';
diRecvSocket: DINT;
bySend : ARRAY[0..10] OF BYTE := 0,1,2,3,4,5,6,7,8,9,10;
bSent: BOOL := TRUE;
bActive: BOOL := TRUE;
END_VAR

IF bActive THEN
IF diSendSocket = 0 THEN
diSendSocket := UdpOpenSendSocket(iPort);
END_IF

IF diSendSocket > 0 AND bSent THEN
bSent := FALSE;
UdpSendData(diSendSocket, iPort, stDestIPAddress, ADR(bySend), SIZEOF(bySend));
END_IF
END_IF

in simulation this does not work, as the target is not the asame.
so it does not know how to deal with it.
