If the permissions are found to be incorrect an error message is displayed and the session is not started. Windows Remote Desktop session starting timeout (sec) - This timeout is only used if the property Use same working folder for all Remote Desktop sessions is selected in a clients network configuration. As only one RDS client is able to start at a time in a host server, the next client must wait either until the previous client has completed its startup, or this delay, before it can start. Common server properties for WebVue and the Web Services Toolkit Enable property server - Enable the Web Services property server. The default is ticked. Channel port - The port used for local communication between the Supervisor and IIS on the host PC. If a firewall is operating on the host PC it may be necessary to add an exception for the Supervisor and the port that it is using. The default is 8090. Client session timeout (sec) - If there is no request from the client after this period has elapsed, the server assumes that the client is disconnected, removes the clients context and releases any server resources allocated to the client. The default is 300 seconds. Webvue - See the Advanced Settings topic in the WebVue book. Mobile server - See the Settings topic in the Mobile Server book. OPC server - See the Settings topic in the OPC Server book.When basing the architecture on a RDS Host Server, only one Supervisor instance can have Enable property server enabled.Using HTTPS to Secure the Connection Between the Supervisor and its Web ComponentsThe standard communication used by the Supervisor (via Windows Internet Information Services) to communicate with its Web components is HTTP. HTTP is not encrypted and therefore represents a security risk. To fulfill the normally recognized minimum IT security requirements you can alternatively use HTTPS (Hypertext Transfer Protocol Secure). To use HTTPS you must obtain or configure an SSL Certificate (also known as a Security Certificate) for IIS. The Security Certificate contains (amongst other things) a key which is used to encrypt the communication. A Security Certificate can either be obtained from a Certificate Authority or can be self generated known as a self-signed certificate. Which one you use will depend on the IT policy of your company. This topic explains how to configure a self-signed certificate.How to configure IIS to allow the use HTTPS using a self-signed Security Certificate1. Open the IIS Manager (Control Panel System and Security Administrative Tools).2. Create a Self-Signed Certificate.a. Navigate the left pane and select your computer. b. Scroll the center pane and double click the Server Certificates tool. Show picturec. In the right pane select the Create Self-Signed Certificate task. The certificate configuration dialog opens.d.

Close the IIS Manager dialog. The configuration is complete.The Supervisor can now communicate with its Web components using either HTTP or HTTPS.Allowing only a secure connectionIf you want to only allow secure connections, return to the Default Web Site view and double click on the SSL Settings tool. Tick the Require SSL box and click the Apply task in the right pane. Show pictureNow the Supervisor is only able to connect to its Web components using a secure connection.Web Services Server OverviewThe topics in this Help book explain how to configure the WebVue and Web Services server. For detailed information on how to configure and use WebVue itself, see the main WebVue help book.What are Virtual Directories?The term virtual directory is used to describe the mechanism that allows a Web client to access files located on a server using an alias rather than the real location. Using an alias to access files has several advantages. Because an alias is usually shorter than the path name of the directory, it is more convenient for users to type. An alias is more secure as users do not know where your files are physically located and therefore cannot use that information to modify your files. Aliases make it easier for you to move the location of your application. Rather than changing the URL for the directory, you change the mapping between the alias and the physical location of the directory.Virtual directories used by Web ServicesThe following virtual directories are used by Web Services. Classes - Used by the WebVue client to load the Java applet. WebPropertyServer - Used by the WebVue client to exchange data with its server. ProjectName - Used by the WebVue client to access the configuration of the project. (ProjectName is replaced by the actual name of the project.) Virtual directories used by the Web Services ToolkitThe following virtual directories are used by the Web Services Toolkit. They are used by any third party applications. SessionContext - to access session and user management. RealTimeData - to access the real time value of the Supervisors variables. RealTimeAlarm - to access the Supervisors alarm list. HistoricalData - to access the Supervisors historical data.Virtual directories used by the demonstration portalsThe supervisor is shipped with an example of web portal that use the Web Services Toolkit to access the Supervisors data. It also require virtual directories. SV_WSDemo_100Accessing the virtual directory configuration in Windows 7You can access the virtual directory configuration as follows.1. From the Start menu open the Windows Control Panel.2. Open the System and Security section then Administrative Tools.3. Open the dialog for Internet Information Services (IIS Manager).4. In the Connections pane, expand the PCs root node, then Sites, then the Default Web Site. Under that you will see a list of the virtual directories set up by the Supervisor. 5. To view the properties of a virtual directory right-click its icon and, from the context menu, select Manage Application then Advanced Settings. Show pictureDo not change anything in the virtual directory configuration unless you are confident about what you are doing. An incorrect change may cause erroneous operation of the Supervisor, Web Services or Windows.The virtual directories are only created after the Web Services Server has been configured. See the topic Setting up the IIS Virtual Directories for more information.How to Set-up the IIS Virtual Directories for WebVue or WebServices1. Select the Servers folder in the Application Explorer configuration tree and then, in the right pane, select the WebVue & Web Services object.2. From the task list select Setup IIS virtual directories and click Continue on the confirmation dialog. Show picture3. The Supervisor will attempt to configure the virtual directories and a dialog will be displayed confirming the results. Click the Finished button to close the confirmation dialog.The virtual directories must be correctly set-up before you can use WebVue or Web Services. If the set-up fails check the configuration of IIS on your PC. See the main WebVue and Web Services help book for further information. WebVue and Web Services Server Startup SettingsThe WebVue and Web Services server startup settings can be displayed from the Communication folder of the Application Explorers Main Settings dialog or by using the Settings task when the WebVue and Web Services folder is selected in the Application Explorers configuration tree. Show picture Default first mimic and branch - Selects the mimic and branch that are displayed in the WebVue Client when it first connects to the Supervisor if a mimic and branch are not defined in configuration of the user that has logged on. Display language - Specifies the language in which the WebVue menu and tools will appear. Project language - Specifies the language in which the WebVue mimics will appear. Look and feel - Selects the look and feel of the WebVue Client system menu, pop-up menus and HTML workspace.WebVue and Web Services Server Advanced SettingsThe WebVue and Web Services server advanced settings can be displayed from the Communication folder of the Application Explorers Main Settings dialog or by using the Settings task when the WebVue and Web Services folder is selected in the Application Explorers configuration tree.Show picture Ergonomics Show system menu - Display the WebVue command menu when WebVue is displayed in a browser. Activate anti-aliasing - Activate anti-aliasing of text and graphics in WebVue. Behavior Access to layers on right click - Enable the ability to select drawing layers (from the pop-up menu displayed by-right clicking in a WebVue mimic). Contextual mimics - Allow the use of context mimics in WebVue. Enable automatic logoff - Enable automatic logging off after a period of inactivity. The period is defined in the users profile. Security mode for login and password - See the topic Using the security mode for password in the main WebVue help. Associated Action on left click - In an Alarm Viewer, enable the action associated with an alarm to be directly executed when the user left-clicks on the alarm. Link mimic with web client resolution - The mimics size is adjusted to use the screen resolution of the PC used by the web client. See note below. Connection Data encryption - Data transferred between the WebVue Client and Server is encrypted. When data transfers are encrypted, they are far less vulnerable to techniques of sniffing (unauthorized monitoring) and spoofing (impersonating a client or server). Data compression - Data transferred between the WebVue server and client is compressed using a Zip type algorithm. Logon/logout script - Enables a script to run at logon and/or logout. Viewers parameters Client polling delay- The period at which the WebVue Client makes requests to the server. Read after click period (ms)- The period following a command click in a WebVue mimic after which the WebVue client makes a read request. Trend, Log & Alarm refresh periods (ms) - The period for refreshing the content of each kind of viewer.The properties that enabled certain SCADA Basic functions (Enable CONNECTURL, etc.) are not required from version 10.0 onwards as the SCADA Basic functions to which they relate are now permanently enabled.Using Link mimic with web client resolutionWhen you tick Link mimic with web client resolution the client (WebVue) sends the screen resolution of the PC on which it is running to the Supervisor. The Supervisors server then automatically scales mimics requested by WebVue so that they fit the screen resolution of the client. However, if the Web Browser containing WebVue is not full screen, then the mimics will not be fully visible as they will be scaled to fit the full screen. To resolve this you must edit index.html to add a the following line.For Internet Explorer: nFor other browsers:autofit=browsern in index.htmlThis will cause the client to send the resolution of the Web Browser to the server instead of sending the screen resolution. The Web Browser resolution is then used to scale the mimics.The index.html file is found in the folder .WEB.When you tick Link mimic with web client resolution the client (WebVue) sends the screen resolution of the host PC on which it is running to the server (the Supervisor). The Supervisors server then automatically scales mimics requested by WebVue so that they fit the screen resolution of the client.Mobile Server OverviewThe topics in this Help book explain how to configure the Supervisors Mobile Server. For detailed information on how to configure and use TouchVue, the Supervisors mobile app, see the main TouchVue help book.Mobile Server Settings - Alarms TabThe Mobile Server advanced settings can be displayed from the Communication folder of the Application Explorers Main Settings dialog or by using the Settings task when the Mobile Server folder is selected in the Application Explorers configuration tree.
