I am trying to implement a TCP/IP application in codesys using the SysLibSocket.lib.
Here is my piece of code for creating the socket and binding it. But the bind function always return False. Can any one pls help me to find out whats wrong or missing in the code.
SocketCreateHandle := SysSockCreate(SOCKET_AF_INET, SOCKET_STREAM, 0);
SocketAddress.sin_family := SOCKET_AF_INET ;
InetAddr := '201.65.32.177';
SocketAddress.sin_addr := SysSockInetAddr(InetAddr);
SocketAddress.sin_port := SysSockHtons(3000);
bResult := SysSockBind(SocketCreateHandle, ADR(SocketAddress), SIZEOF(SocketAddress));
IF bResult THEN
// here it always returns false
END_IF
If anyone has any sample program for implementing TCP/IP server or client in Codesys, pls share with me or any useful link would be highly appreciated.
Thanks in advance
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I think you should have posted this in the V2.3 section, because you are looking for a .lib example.
Anyway, a very good example can be found through the website w www.3s-software.com w .
Select the menu Download=>CoDeSys Sample Projects.
Go to the ftp site and choose: /Projects/CoDeSysV2.3/Communication/TcpIp/
See the pdf file and example project.
