Setting Time Limits on Client Control

With the Web Server, you can set a time limit on how long a remote client can control a VI when multiple clients are waiting to control the VI. You should set a time limit to guarantee that every client has a chance to obtain control of the VI. When a particular client reaches the time limit, the next client in the queue is the controller. However, all clients still can view the front panel.

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 a second client never requests control of the VI, then the initial client never loses control of the VI.

Complete the following steps to set the time limit on how long each client can control a particular VI.

  1. Select Tools»Options to display the Options dialog box.
  2. Select Web Server from the Category list.
  3. Click a VI in the Visible VIs list in the Visible VIs section. If no VIs appear in the list, you need to add visible VI entries to the list and then select it.
  4. Place a checkmark in the Allow access checkbox.
  5. If you want to change the default time limit, remove the checkmark from the Use default checkbox. The default is 300 seconds.
  6. In the Control time limit (sec) field, enter the amount of time in seconds you want to allow each client to control the front panel of the VI you selected in the Visible VIs list.
  7. Click the OK button.
