Internal error codes of the TwinCAT TCP/IP Connection Server
Code (hex) | Code (dec) | Symbolic constant | Description |
|---|---|---|---|
0x00008001 | 32769 | TCPADSERROR_NOMOREENTRIES | No new sockets can be created (for FB_SocketListen and FB_SocketConnect). |
0x00008002 | 32770 | TCPADSERROR_NOTFOUND | Socket handle is invalid (for FB_SocketReceive, FB_SocketAccept, FB_SocketSend etc.). |
0x00008003 | 32771 | TCPADSERROR_ALREADYEXISTS | Is returned when FB_SocketListen is called, if the TcpIp port listener already exists. |
0x00008004 | 32772 | TCPADSERROR_NOTCONNECTED | Is returned when FB_SocketReceive is called, if the client socket is no longer connected with the server. |
0x00008005 | 32773 | TCPADSERROR_NOTLISTENING | Is returned when FB_SocketAccept is called, if an error was registered in the listener socket. |
0x00008006 | 32774 | TCPADSERROR_HOST_NOT_FOUND | Returned if the target system is not reachable. |
0x00008080 | 32896 | TCPADSERROR_TLS_INVALID_STATE | Returned if FB_TlsSocketAddCa, FB_TlsSocketAddCrl , FB_TlsSocketSetCert or FB_TlsSocketSetPsk are called and a Connect has already been called. |
0x00008081 | 32897 | TCPADSERROR_TLS_CA_NOTFOUND | Returned if the specified CA certificate was not found. |
0x00008082 | 32898 | TCPADSERROR_TLS_CERT_NOTFOUND | Returned if the specified certificate file was not found. |
0x00008083 | 32899 | TCPADSERROR_TLS_KEY_NOTFOUND | Returned if the specified file with the private key was not found. |
0x00008084 | 32900 | TCPADSERROR_TLS_CA_INVALID | Returned if the specified CA certificate could not be read or is invalid. |
0x00008085 | 32901 | TCPADSERROR_TLS_CERT_INVALID | Returned if the specified certificate file could not be read or is invalid. |
0x00008086 | 32902 | TCPADSERROR_TLS_KEY_INVALID | Returned if the specified private key could not be read or is invalid. |
0x00008087 | 32903 | TCPADSERROR_TLS_VERIFY_FAIL | Returned if the remote terminal could not be verified during the TLS handshake. |
0x00008088 | 32904 | TCPADSERROR_TLS_SETUP | Returned if a general error occurred while setting up the TLS connection. |
0x00008089 | 32905 | TCPADSERROR_TLS_HANDSHAKE_FAIL | Returned if an error occurred during the TLS handshake. Usually the handshake always works. However, if there are connection problems during the handshake, it may fail. |
0x0000808A | 32906 | TCPADSERROR_TLS_CIPHER_INVALID | Returned if an invalid cipher suite was specified. |
0x0000808B | 32907 | TCPADSERROR_TLS_VERSION_INVALID | Returned if an invalid TLS version was specified. |
0x0000808C | 32908 | TCPADSERROR_TLS_CRL_INVALID | Returned if the specified Certificate Revocation List (CRL) is invalid. |
0x0000808D | 32909 | TCPADSERROR_TLS_INTERNAL_ERROR | Returned if an internal error occurred while setting up the TLS connection. |
0x0000808E | 32910 | TCPADSERROR_TLS_PSK_SETUP_ERROR | Returned if an error occurred when using a PreSharedKey (PSK) for TLS. |
0x0000808F | 32911 | TCPADSERROR_TLS_CN_MISMATCH | Returned if the CommonName in the certificate of the remote terminal does not match the host name or IP address used. |
0x00008090 | 32912 | TCPADSERROR_TLS_CERT_EXPIRED | Returned when the certificate of the remote terminal has expired. |
0x00008091 | 32913 | TCPADSERROR_TLS_CERT_REVOKED | Returned when the certificate of the remote terminal has been revoked. |
0x00008092 | 32914 | TCPADSERROR_TLS_CERT_MISSING | Returned when the remote terminal did not submit a certificate. |
