Enumeration |
|
Available as of: |
V1.0.9.0 |
The enumeration ET_Result contains the possible values that indicate the result of operations executed by the function block.
The values 0 to 99 are used to indicate the result of the operations executed by the function blocks FB_TCPClient/FB_TCPClient2, FB_TCPServer/FB_TCPServer2, and FB_UDPPeer.
|
Name |
Value |
Description |
|---|---|---|
|
0 |
The operation completed successfully. |
|
|
1 |
The operation was not completed successfully. |
|
|
10 |
The requested operation cannot be executed in the present state or the property Result was different than Ok prior to the function call. |
|
|
11 |
The requested operation is not supported by this controller. |
|
|
12 |
The requested port address is already in use. |
|
|
13 |
The requested IP address is not available since it is not configured on any Ethernet interface. |
|
|
20 |
The value is outside of the valid range. |
|
|
21 |
The value of the input specifying the receive buffer size is outside of the valid range. |
|
|
22 |
The value of the input specifying the number of bytes to send is outside of the valid range. |
|
|
23 |
The value of the input specifying the fill level of the buffer is outside of the valid range. |
|
|
24 |
Only 1 byte of OutOfBand-data is allowed but a larger size was requested. |
|
|
25 |
The address of the buffer is invalid. |
|
|
26 |
The given IP address is not valid. |
|
|
27 |
The given IP address is not valid or not in the range of multicast addresses. |
|
|
28 |
The client specified could not be found since it is not connected to the TCP server. |
|
|
40 |
The requested operation cannot be executed since the remote site has already closed the connection. |
|
|
41 |
The attempt to establish a connection has timed out because the remote system is not available or is not answering the request. |
|
|
42 |
The attempt to establish a connection is unsuccessful because the remote system denied it. |
|
|
50 |
The requested operation cannot be executed because there are not enough configurable internal resources available. Try using a smaller amount of data for one call. |
|
|
51 |
The socket cannot be opened since the size of the internal socket management list is insufficient. Close an already open socket or increase the value of Gc_uiSocketManagementListSize in the global parameter list (GPL). |
|
|
52 |
The TCP server cannot have any more clients. Disconnect an existing client or increase the value of Gc_uiTCPServerMaxConnections in the global parameter list (GPL). |
|
|
53 |
The requested number of bytes to send exceeds the limit. Reduce the amount of data to be sent or increase the value of Gc_udiTCPServerMaxSendToAllSize in the global parameter list (GPL). |
|
|
54 |
The send buffer of the TCP stack is full, no more data can be copied. Increase send buffer size using the respective socket option or try to send again later. |
|
|
56 |
The specified certificate could not be found in the certificate store of the controller. |
|
|
57 |
Only available for FB_TcpServer2 The TLS (Transport Layer Security) handshake could not be completed. If the parameter etCertVerifyMode is set to AllCertificates or TrustedOnly, verify that the client sends a certificate and, if required, that it is categorized as trusted. |
|
|
58 |
Internal error detected while initializing the TLS context. Up to 10 different TLS contexts can be open at the same time. Ensure that not more than 10 TCP sockets using TLS are open at the same time. |
|
|
60 |
Internal error detected while initializing the async manager. The use of the async manager can be configured by the global variables GVL.G_xDisableAsyncExecTcpClient and GVL.G_xDisableAsyncExecTcpServer. |
|
|
61 |
Internal error detected while starting the async job. The use of the async manager can be configured by the global variables GVL.G_xDisableAsyncExecTcpClient and GVL.G_xDisableAsyncExecTcpServer. |
The values 1001 to 1100 are used to indicate the status of the function block FB_DnsClient. If q_xError of the function block is FALSE, one of the following status messages is provided through the q_etResult.
