Limiting time for idle, active, or disconnected sessions

As an Administrator, you can set time limits for individual users for limiting active sessions and idle sessions, and for ending a disconnected session. To set these preferences, select StartControl PanelAdministrative ToolsComputer Management. Under Local Users and Groups, select Users, and double-click the user name in the right-hand pane. The Sessions tab on the user Properties dialog provides options for setting time limits and for allowing reconnection. It is not recommended that you restrict active sessions unless you are likely to have more remote users than remote sessions available. In that case, you may want to increase the number of Remote Client servers. Contact your Emerson representative for information.

You can also override individual user settings for these options using Remote Desktop Session Host Configuration. To access the Remote Desktop Session Host Configuration dialog, click StartControl PanelAdministrative ToolsRemote Desktop Services and double-click Remote Desktop Session Host Configuration. On the RDP-Tcp Properties dialog, select the Sessions tab, click Override user settings, and use the drop-down boxes to select the preferred time options for the following:

Disconnecting a Session vs. Ending a Session

You can decide whether the session should be disconnected or ended when the session limit is reached or the connection is broken. When you specify that a client session is to be disconnected, the client can reconnect if needed (and if reconnection is allowed). When you specify that a client session is to be ended, the session is reset and cannot be reconnected. The remote user would need to open a new client session if one is available. It is not recommended that you set these limits unless you have more remote users than remote sessions available.

How DeltaV Ends Disconnected and Idle Sessions

DeltaV handles ending a disconnected session slightly differently than ending an idle session, as described below. In both cases the time limit to end the disconnected or idle session is 30 minutes:

  • Disconnected session - Approximately 2 minutes before the 30-minute time limit is reached, DeltaV applications running in the session exit. The session ends in 30 minutes.
  • Idle session - At the 30-minute time limit, DeltaV applications running in the session exit. The session ends 2 minutes after the time limit.

The example below shows how these options might be configured. Note that the option to allow reconnection defaults to From any client and the option to Override user settings is grayed out (not available). (The other option, to allow reconnection From previous client is supported by Windows Remote Desktop Services only for Citrix ICA-based clients that provide a serial number when connecting.)

As an Administrator, you may want to set up guidelines for ending disconnected sessions and to inform remote users of these time limits. For instance, you might want to allow Engineering sessions to be reconnected within 30 minutes after a session connection is broken so that work in progress is not lost. Since Operator sessions do not usually require saving work in progress, you may choose to end disconnected Operator sessions after only 5 minutes.
