DeltaV Mobile

In process manufacturing the operator station allows operators to rapidly assess a set of distinct systems or situations under their span-of-responsibility and determine where attention is needed on a moment-by-moment basis. If a problem exists, the features of the operator station directs the operators to displays from which they can troubleshoot and take action. So what if the operator is not in the control room? or there are additional workers outside of the control room who require access to the same information? This is where mobile solutions fit in. Mobile is the subject of this posting.
All of us in our daily lives have become addicted to our mobile devices. We use our phones to check the weather, news, and football scores. We use these same devices to stay in touch with our colleagues and family. So how about using our phones and mobile devices to support our jobs? To do this mobile devices need to be able to be customized for each person’s role. For the example a specific operator may be responsible for one of the crude units and several diesel hydrotreaters. Other workers, for example someone responsible for environmental operations, may be interested in just the environmental parameters and alarms. Going further, users are not ‘at work’ 24×7. While they are at work or on call, they would like to be able to stay in-touch with the plant, otherwise they would like to enjoy downtime. So how can these needs be served by mobile solutions?
To address these needs DeltaV Mobile provides a configurable series of view lists and notifications that can be used to represent a wide range of interests covering process and plant equipment, user roles, and times when the user is active in plant operations. These view lists may be watch lists, alarm lists and other lists. As an example, a watch list for a diesel hydrotreater may be set up as shown below:

The order of the parameters in the list may be customized by the user from their mobile device or through the web configuration application.
In this example the watchlist is identified with the name ‘DHT1’. Key parameters, for example, Furnace Out Temp, are included in the list. From this view users may drill into watch list details as shown below:

Users may drill even further into details by changing the orientation to landscape, this is shown below:

Likewise, alarm lists may be configured to represent any part of the system and the process that is being monitored. An alarm list for the same diesel hydrotreater is shown below:

Similar to watchlists, users may further drill into details as shown below:

Another aspect of view lists is that they may be shown in summary form. The lists may be combined or shown separately as watch lists, alarm lists, and other lists. This is shown below:

Mobile users enjoy getting the latest updates through notifications. In DeltaV Mobile these notifications may be setup on specific alarms, alerts, calculations, or some other aspect of the system. Notifications may be further restricted by the shift the user is on. Notifications are shown below:

Notifications may use of deep linking. Deep linking allows users to link directly to the application in-context of the notification.
Future blogs will take a deeper look at defining the content that should be shown on these lists and the effort required to integrate mobile into IT systems.
