VIs and functions that use TCP connections in LabVIEW and VI Server properties and methods can return the following error codes. This includes TCP, UDP, DataSocket, Bluetooth, and IrDA VIs and functions, remote front panel connections, and VI Server applications. Remote front panels also can return additional error messages. Refer to the KnowledgeBase for more information about correcting errors in LabVIEW.

53 Manager call not supported.
54 The network address is ill-formed. Make sure the address is in a valid format. For TCP/IP, the address can be either a machine name or an IP address in the form If this error occurs when specifying a machine name, make sure the machine name is valid. Try to ping the machine name. Check that you have a DNS server properly configured. If you are using the TCP Open Connection function, ensure that the value of the remote port or service name is not 0.
55 The network operation is in progress. If you receive this error while using the UDP Write function, refer to the KnowledgeBase at for more information.
56 The network operation exceeded the user-specified or system time limit.
57 The network connection is busy.
58 The network function is not supported by the system.
59 The network is down, unreachable, or has been reset.
60 The specified port or network address is currently in use. Select an available port or network address.
61 The system could not allocate the necessary memory.
62 The system caused the network connection to be aborted.
63 The network connection was refused by the server. For TCP/IP, make sure the server is running and listening on the port you want to use. Firewalls also can cause a server to refuse a connection. For VI Server, make sure the VI Server is enabled on the VI Server page of the Options dialog box.
64 The network connection is not yet established.
65 The network connection is already established.
66 The network connection was closed by the peer. If you are using the Open VI Reference function on a remote VI Server connection, verify that the machine is allowed access by selecting Tools»Options»VI Server on the server side.
108 Singlecast connections cannot send to multicast addresses.
109 Multicast connections cannot send to singlecast addresses.
110 Specified IP address is not in multicast address range.
111 Cannot write to read-only multicast connection.
112 Cannot read from write-only multicast connection.
113 A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the datagram itself.
114 Could not create TCP listener port because the port, service name, or net address conflict with a TCP listener that already exists.
119 Illegal combination of Bluetooth discoverable and non-connectable modes. A discoverable Bluetooth system is connectable, and non-connectable Bluetooth system is non-discoverable. The combination of discoverable and non-connectable is illegal.
120 Error setting Bluetooth mode. Unknown internal error encountered while setting Bluetooth mode.
121 Invalid GUID string. The GUID string has an invalid format. An example of the correct format is: B62C4E8D-62CC-404b-BBBF-BF3E3BBB1374.
126 Could not query socket state. Either the socket is in a bad state (e.g. an error state, not connected, and so on) and the requested information is not available, or the socket is unable to answer the query.
127 The specified socket is not an IPv4 socket.
1101 Insufficient privileges to read, write, or create an item in the DataSocket Server. Use the DataSocket Server Manager to configure these privileges.
1114 This item is read-only. You must connect in read mode.
1115 This item is write-only. You must connect in write mode.
1132 Busy with another operation.
1133 LabVIEW is busy connecting.
1134 A different read operation is in progress.
1139 A DataSocket item name cannot contain certain characters. This error occurs if the DataSocket item name contains "/", "\", "?", "=", or "&".
1140 Exceeded maximum DataSocket item count. Use the DataSocket Server Manager to change the maximum number of dynamically created items the data server will allow.
1141 Exceeded maximum data item connection count. Use the DataSocket Server Manager to change the maximum number of connections the data server will allow.
1142 Multiple writers are not allowed. You can use the Shared Variable Properties dialog box to configure shared variables to accept multiple writers.
1143 Cannot load dataskt.llb.
1178 LabVIEW reached end of file.
1179 Access mode not supported for operation.
1180 Pending operation in progress.
1181 Protocol not recognized by LabVIEW. You must use a valid URL to establish a data connection.
1182 Error parsing URL.
1183 Synchronous operation not supported for connection. Append "?sync=true" to URL to enable synchronous operations with the PSP protocol. LabVIEW 8.0.1 and later support synchronous operations.
1184 Path not found, FTP login incorrect, or no FTP write permission.
1185 OPC item not found.
1337 Not enough memory to complete this remote panel operation.
1338 Network type not supported by remote panel protocol.
1339 Remote panel connection is closed.
1340 Invalid server IP address. Contact the server administrator to get the correct IP address or name of the computer to which you want to connect.
1341 Remote panel connection refused by the specified server. The server administrator must enable the LabVIEW Web Server. Verify that the Server IP Address and Port you entered in the Connect to Remote Panel dialog box are correct.
1343 Client does not have access to remote panel server.
1344 The remote panel protocol version is incompatible. The client and server computers must be running the same version of LabVIEW. If you are using a browser to view and control a remote front panel, you must use a version of the LabVIEW Run-Time Engine compatible with the version of LabVIEW on the server computer. Also, be sure and contact the server administrator and have them make sure that the HTML document specifies the correct version of the LabVIEW Run-Time Engine.
1345 The LabVIEW client version is incompatible with the LabVIEW server version. Make sure you entered the IP address or computer name of the server correctly.
1346 Server does not support remote panels.
1347 You cannot connect to the local LabVIEW application.
1348 Remote panel server failed to send the requested VI. A memory or network problem occurred. This error might occur if you try to connect to a large front panel. Try to connect to the front panel again, or request that the server administrator modify the front panel so it uses less memory.
1349 Client does not have access to specified VI. The server administrator must specify the VIs that clients can view or control.
1350 Requested VI is broken and cannot be viewed or controlled.
1351 Requested VI is not a standard VI. You cannot view or control a polymorphic VI, custom control, or global variable VI remotely.
1352 Requested VI is not loaded into memory on the server computer.
1353 Requested VI is not in run mode.
1354 VI name required.
1355 Fatal error occurred during operation, closing connection.
1356 A remote panel connection does not exist for the specified VI.
1369 Removing data connection from this control.
1383 The data type of the data read does not match the data type of the type input.
1509 The response from the NI Service Locator is not a valid HTTP response.
1510 The requested service was not found as a registered service with the NI Service Locator. To correct this error, check that the desired service name is correct. If the service name is correct, check that either the TCP Create Listener, or the UDP Open functions are registering the service.
1511 The requested service is a registered service with the NI Service Locator but it did not contain a port mapping. The port number is missing or is registered incorrectly.
1567 The control is not located in the same VI as the control reference. You can link a control reference only to controls or indicators in the same VI.
2308 Found no configured network adapters.
363515 The file exceeds the size limit on the server.
