Network Browser device discovery guidelines

Observe these discovery guidelines for viewing devices in a network topology in the
Network Browser
 dialog:
  • A red X on a device indicates a communication status error exists with a node. For example, if Auto browse is enabled, the communication software edition recognizes nodes during the browse cycle and stores the node information. To remove a device with a red X from the topology tree, right-click the node and select
    Remove
    .
  • A device with a yellow question mark indicates an unknown device. This occurs when the device does not have an associated EDS file installed. In this case, the correct online name displays but the icon does not appear. To resolve this condition:
    2. Register the EDS file with the
      FactoryTalk Linx
       EDS Hardware Installation tool: At the top of the
      Network Browser
      , select the down arrow and then select
      EDS / Device Description Auto Upload
      .
    TIP: Some devices have embedded EDS files. To upload the EDS file from the device, right-click the device in the
    FactoryTalk Linx
     topology tree and select
    EDS / Device Description Upload
    .
  • A device with a red X and yellow question mark appears when an Ethernet driver communicates with an IP address without an attached physical device. The communication software edition displays the device name as Unrecognized Device.
    To resolve this condition, add the correct IP address for the device to communicate with the Ethernet driver.
    TIP: Some devices do not have EDS files and display with a question mark in the topology.
  • Use the Auto browse automatic discovery function to continually browse a selected device or network for real-time status updates. For example, the browser recognizes nodes during the browse cycle and stores the node information. If an error occurs, such as a communication cable being pulled from a device, the browser places a red X over the device indicating no detection.
    TIP: When browsing certain networks, such as through a 1785-KA, status may take longer to update. In these cases, the browser is checking all station addresses.
  • When the network or device is collapsed, select the arrowhead icon to expand the view and begin browsing. Double-clicking the network or device icon also expands the view for browsing. When the network or device is expanded, click the applicable collapse icon or double-click the network or device icon to collapse the view.
