Log on to the Mobile Access web interface

Log on to the Mobile Access web interface to view the configured alarms, process values, trends, and project screens during run time.

The Mobile Access web interface uses HTML5 (including CSS3 and AJAX) to create animated graphics and perform real-time data exchange. That means you must use an HTML5-compatible browser to access the web interface. Most modern browsers are HTML5-compatible, but browsers are updated frequently and the HTML5 specification itself is still being revised, so we cannot provide a comprehensive list of browsers that can be used with Mobile Access.

That being said, we recommend you use either Microsoft Edge or Google Chrome. They are available for most platforms and operating systems, and we have found that they provide the best overall performance and compatibility.

We do not support any version of Internet Explorer for use with Mobile Access.

Note: If the URL does not specify a screen, Mobile Access opens the project's startup screen.

To log on to your project's Mobile Access web interface:

1. On your computer or mobile device, use the web browser to go to the Mobile Access Logon page:

   https://<server address>/ma/

   You should always include the HTTPS protocol (https://) before the server address in order to connect securely via SSL. If you do not, your connection might not be secure or the server might not allow you to connect at all, depending on how it is configured. For more information, see Enable SSL encryption in Microsoft IIS.

   For <server address>, do one of the following:

   • If the server is a computer on your local network, type the host name (or IP address, if you know it) of that computer. For example:

     https://station01/ma/

   • If the server is a computer on the Internet, type is the full domain name (or IP address, if you know it) of that computer. For example:

     https://scada.ourcompany.com/ma/

   • If the server is located behind a network router that has been configured to do port forwarding, type the public IP address of that router followed by the port number that has been assigned to the server. For example:

     https://200.128.128.0:3040/ma/

   The Mobile Access Logon page is displayed in the browser.

   

   If you are not connecting via SSL, a message is also displayed to remind you that your connection is not secure.

   If you are connecting via SSL for the first time, you may be prompted to accept the host's SSL certificate. This is done automatically for most certificates issued by trusted Certificate Authorities, but if your web server is using a self-signed certificate, you may need to manually install that certificate on your computer or mobile device. The procedure to do this varies by operating system, so for more information, consult the documentation for your computer or mobile device.

2. Type your user name and password in the respective boxes in the Mobile Access Logon page, and then either press Return on your keyboard or click/tap the green arrow. To log on as the guest user, add guestuser=1 to the URL. Other values are ignored.

   You are logged on to the Mobile Access web interface, and the home screen is displayed. If the URL does not specify a screen, Mobile Access opens the project's startup screen.

   Alternatively, an alert message might be displayed when you try to log on. Remember the project runtime server and the web server are two separate processes; if the project is not running, you may be able to go to the Mobile Access Logon page but you will not be able to log on to the project. Make sure the project is running, and then try again.

You can open only one session of the Mobile Access web interface per browser. You cannot open new sessions in additional tabs or even in additional instances of the same browser. So, for example, if you want to open two sessions of the web interface on the same computer, you must open the first in Google Chrome and the second in Microsoft Edge.

To log off from the Mobile Access web interface, click/tap the Return button to return to the home screen, and then on the home screen, click/tap Log Off.
