Error 54 occurred at TCP Open Connection in SubscriberRequestTopic.vi:6580011->ROSSubscriber.vi:2780005->ROSSubscriber.vi.ACBRProxyCaller.86E0003F Possible reason(s): LabVIEW: (Hex 0x36) 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 xxx.xxx.xxx.xxx. 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.
