If your FieldDAQ device becomes disconnected from the network, open MAX and try the following:

  • After moving the device to a new network, NI-DAQmx may lose connection to the device. In this case, click Reconnect to provide NI-DAQmx with the new hostname or IP address.
  • The FieldDAQ device icon indicates whether it is recognized and present on the network. If a connected device appears as disconnected in the configuration tree in MAX, select Self-Test or Reset. If successful, the device icon changes to dark grey.
