Web Server: Visible VIs Options Page

Select Tools»Options to display the Options dialog box and select Web Server: Visible VIs from the Category list to display this page.

Use this page to configure and edit the list of VIs that are visible on the Web.

This page includes the following components:

  • Visible VIs—Lists the VIs that are visible through the Web Server. A green checkmark appears to the left of the item when you allow access, and a red X appears when you deny access. If an entry does not have a green checkmark or a red X by its name, the syntax for the entry is incorrect.
  • Currently selected VI—Enter a VI to list in Visible VIs. You can use wildcards in the VI name or directory path you enter. To specify a VI that is part of a LabVIEW project, you must include the project name, the project library, and the target in the path of the VI, when applicable. For example, if MyVI.vi resides in a project called MyProject.lvproj under target My Computer, enter the VI name as MyProject.lvproj/My Computer/MyVI.vi. If the VI is owned by a project library called MyLibrary, also include the project library in the path, as in MyProject.lvproj/My Computer/MyLibrary:MyVI.vi. If the VI is not in a project or project library, you can enter the VI name without any additional information.
  • Allow Access—If selected, LabVIEW allows access to the VI selected in the Visible VIs list. This option is selected by default.
  • Deny Access—If selected, LabVIEW denies access to the VI selected in the Visible VIs list.
  • Control Time Limit (sec)—Specifies the amount of time in seconds a remote client can control a VI in the Visible VIs list when multiple clients are waiting to control the VI. The default is 300 seconds. If Use default is checked, you cannot edit this field.

    Note  LabVIEW does not begin monitoring the time limit set on a particular VI until a second client requests control of the same VI. If another client requests control, LabVIEW begins monitoring the control time limit. If a second client never requests control of the VI, then the initial client never loses control of the VI.
    • Use default—Sets Control Time Limit to its default value of 300 seconds. This checkbox is checked by default. To edit Control Time Limit, remove the checkmark from the checkbox.
  • Add—Adds a new entry to the Visible VIs list. The new entry appears below the selected entry in the Visible VIs list.
  • Remove—Removes the selected entry from the Visible VIs list.

You also can use the Web Server:VI Access List property to allow and deny access to VIs programmatically.
