How do you make PC network release visible for the file browser of your HMI operating unit?

  • Entry
  • Associated product(s)
On an HMI operating unit with network connection no PC network releases of a PC in the network are visible in the file browser.

Test environment

  • A Comfort Panel was used as HMI operating unit.
  • The HMI operating unit is connected with a PC via Ethernet.
  • The name of the PC is "HMI-1".
  • The PC has a folder release named "DataExchange".
  • The "ReadMe.txt" file has been stored in the "DataExchange" folder.
  • The network settings have all the settings required for the name service. This is absolutely necessary for the HMI operating unit to access a network folder.

    The fully qualified network path on the PC is thus: \\HMI-1\DataExchange\ReadMe.txt

    Note
    In the "Further Information" section at the end of the entry there are links to two other entries in which the necessary network settings are described.

Standard procedure

  • On the Desktop of your HMI operating unit you open the "My Computer" link.

  • In the file browser you open the "Network" folder.

  • The "Network" folder contains both the network path "\\HMI-1\DataExchange" of the PC and the "ReadMe.txt" file contained in it that is not visible.

  • In the address bar of the file browser you enter the network path "\\HMI-1\DataExchange".
    Enter the user name and password for access to the PC network release.

    Note
    You can also permanently store the PC logon data on the HMI operating unit.
    For this you open the "Settings" in the "Start Center" (Fig. 01) and then the "Network ID" link. Now you enter the logon data for the PC.

  • The "ReadMe.txt" file is displayed.

Solution

  • On the HMI operating unit you open the command prompt via "Start > Programs > Command Prompt".

  • Enter the following command: "net use logs \\HMI-1\DataExchange".
    Complete your entries with the Return key.

  • Quit the command prompt via "File > Close".

  • In the file browser you open the "Network" folder and then the "logs" folder.
    Enter the user name and password required for access to the PC network release.


    Fig. 09
  • Now you see the "ReadMe.txt" file in the network path "\\HMI-1\DataExchange".


    Fig. 10
  • Open the "Settings" in the "Start Center" (Fig. 01) and then the "OP" link.

  • Save the settings for the "Network" folder with "Save Registry".

Notes

  • If you want to delete the "logs" folder and the network releases it contains, then enter the following command in the command prompt: "net use logs /d"
  • If you overwrite the firmware of your HMI operating unit, for example when changing the version of your configuration software, you have to re-enter and save the settings for the "Network" folder.
