Mobile Access Tabular<br />

Mobile Access Tabular enables your project to send alarms and process values to cell phones, PDAs, and<br />

other mobile devices.<br />

How It Works<br />

When you enable the Mobile Access Tabular feature in your IWS project and then run your project, IWS<br />

creates a small, ASP-powered website and periodically refreshes it with alarm notifications and whatever tag<br />

values you choose to make available. You can also acknowledge alarms and write new tag values through the<br />

website. As long as the web server — typically Microsoft IIS, because it must support ASP — and network are<br />

properly configured to allow access, all you need to do is point your browser to the website and log on.<br />

Licensing<br />

One Mobile Access Tabular Client is included with every IWS runtime license. That means the Mobile Access<br />

Tabular website will allow only one user to connect at a time. If you want the website to accept more users,<br />

then you must upgrade your license to include additional SMA Clients. For more information, see License<br />

Settings.<br />

Enabling and Configuring Mobile Access Tabular<br />

To enable Mobile Access Tabular and configure the data to be served:<br />

1. On the Graphics tab of the Project Explorer, double-click Thin Clients > Mobile Access Tabular.<br />

The Mobile Access Settings dialog is displayed.<br />

2. Select Enable Mobile Access.<br />

Mobile Access Settings dialog<br />

3. In the LogOn Access Level text-box, type the user security level needed to log on to the website. For more<br />

information about security levels, see Security.<br />

4. The website will show all active alarms to all logged-on users; there is currently no way to show or hide<br />

specific alarms. You can set the user security level needed to acknowledge alarms, however, and it may be<br />

different from the level needed to log on. In the Ack Access Level text-box, type the required level.<br />

5. To have the website show tag values, select Enable in the Process group-box.<br />

6. For each tag you want to show:<br />

a. In the Tag Name column, type the name of tag or double-click to open the Object Finder and select the<br />

tag.<br />
