If you are using the TCP Open Connection function, ensure that the value of the remote port or service name is not 0. Check that you have a DNS server properly configured. If this error occurs when specifying a machine name, make sure the machine name is valid. For TCP/IP, the address can be either a machine name or an IP address in the form. Make sure the address is in a valid format. 54 LabVIEW: The network address is ill-formed.It looks like your inputs are malformed, your timeout are too short, or you are trying to listen on a port that is already in use: How familiar are you with TCP/IP networking in general? (IP addresses, ports, protocols, etc.) You have the following problems, and none are LabVIEW problems. In my code UDP transmitter sending properly but in the UDP receiver err coming as 54, 56 and 60. It is possible that some/all of them may be solved by using a mac address in the above range. Note - I have seen a few threads similar to this one (i.e., 'my Labview Multicast read only works when Wireshark/Ethereal is running') posted over the last couple of years. However, both of them work if I put the destination mac address in the above range. I believe Wireshark is configuring the NIC differently than Labview is (perhaps in a more robust/thorough manner?). When I changed the destination address to something in this range in my multicast tx program, the Labview script started working (without requiring Wireshark to be running). However, according to wikipedia, the range of acceptable multicast addresses is: 01:00:5E:00:00:00 to 01:00:5E:7F:FF:FF. To meet this requirement, I was using a destination mac address with a MSByte of 0x47. In the Source Address field, the first bit is reserved and set to 0. If this bit is 1, it shall indicate that theĪddress field contains a group address that identifies none, one or more, or all of the stations connected Indicate that the address field contains an individual address. Identify the Destination Address either as an individual or as a group address. The first bit (LSB) shall be used in the Destination Address field as an address type designation bit to
