Open MES Web Portal

You can open an MES Web Portal session from a web browser that is running on any node that has network access to the MES Web Portal host.

1. If you are using the Firefox web browser, make sure you are using the latest version.

2. Enter the URL for MES Web Portal.

   Running MES Web Portal requires that you use HTTPS web communications. The default URL is:

   https://<WPhostname>:<HTTPSportnumber>/MES/

   where:

   • <WPhostname> is the fully qualified domain name of the node on which the MES Web Portal host is running (e.g., MESWP.yourorg.com).

   • <HTTPSportnumber> is the HTTPS port number for MES Web Portal. If the MES Web Portal port number is the default HTTPS port number 443, you do not need to include it in the URL.

     See your MES or system administrator for the specific URL that is used for your installation of MES Web Portal.

     Note the following when using the Firefox web browser:

   • If the message Unable to connect appears, make sure that No proxy is selected as the Firefox Network proxy setting. See Set the Firefox Proxy Setting to No Proxy.

   • The first time you enter the MES Web Portal URL, a warning about a potential security risk might appear. This is because Firefox does not recognize the SSL certificate being used by MES Web Portal. Click Advanced, then in the Advanced box click Accept the Risk and Continue.

     The AVEVA Identity Manager login prompt appears.

     

3. Enter your user name and password and click Login.

   Once logged in, the MES Web Portal home page appears.

Your access to pages and functions in MES Web Portal depends on the privileges and line and entity access that have been specified for you. For more information about user privileges and access settings, see the MES Client User Guide or help.

Language Used

The language used in the MES Web Portal browser session for the text is determined by which MES Security Mode is being used (as configured in MES Client):

• If OS Group mode is used, the MES system parameter Default language setting is used.

• If OS User mode is used, the Language setting for your MES user account is used.

The display of localized values and dates is determined by the web browser's language/locale settings. See Set the web browser preferred language and locale .

If Privilege and Access Settings Are Changed During a Session

If your privilege or access settings are changed during an MES Web Portal session, you might see an insufficient privileges message when you attempt to navigate to or use a function to which you no longer have privileges or access. Press the F5 key to refresh the browser; the refreshed MES Web Portal environment will reflect your new privilege and access settings.

Note that your privilege settings are cached, and the cache is automatically refreshed every 2 seconds by default. This refresh rate can be customized for your MES Web Portal host; for modifying the refresh rate, see the chapter "Configuring the MES Web Portal Host" in the MES Installation Guide or online help.

Session Time-Out

For security reasons, after a pre-defined amount to time with no session activity, a log out message appears.

To keep the session open, click OK. Otherwise, after a short period you will be logged out of the session.

The time-out period is based on the Security system parameter Seconds of inactivity before automatic logoff in MES Client.
