The ProSys Solution

An operator’s environment and awareness of the process is critical to the overall safety and performance of the plant. Many tests have shown that execution times and errors can be cut by 50% when using a well-designed operator interface. In fact, many process control systems continue to operate with interface features that are far less clear and concise than what today’s technology can provide. This could be part of the reason for many operator errors. ProSys has a solution to help solve this issue, Interface Dynamics.

Interface Dynamics is a human-machine interface (HMI) shape library that supports process-operator interface goals for:

  • Advanced operator overviews
  • Direct entry
  • Embedded trends
  • Task oriented displays
  • Detailed oriented displays
  • Situational awareness overviews
  • Historical trends and data
  • Operations data
  • Control system data
  • Easily upgradeable

One Display Library

Interface Dynamics was developed to provide operators with a clean, reliable interface. This allows the plant to operate safely by identifying and resolving plant problems quickly and efficiently by identifying areas of operation that are deviating from desired values and encourage operator response. Furthermore, Interface Dynamics can be coupled with AgileOps to enhance the operator’s alarm management experience and reduce the number of operator facing tools.

Overview Shapes

The new shapes enhance its already safe and efficient IDv3 with Variable Bar, Navigation Bar, New and Improved QuickTrends/QuickHourly Standalone Trends and the Embedded Trend Shape. These updates are included in ProSys’ latest version of IDv3 and can be added-on to existing users’ platforms.

Details of the new overview shapes with color configuration using Cascading Style Sheets (CSS) include:

  • Variable bar - Shows a value to the operator in real time, while also providing alarming, acknowledgment and range information. A notable feature is the Rate of Change (ROC) configuration that allows the user to point the shape to a Custom Algorithm Block (CAB) that gives it information on how quickly the Process Variable (PV) is changing and in which direction. 
  • Navigation bar - Provides the operator quick navigation within the display hierarchy with a single mouse click, allowing for navigation to any display within three levels of display hierarchy while also providing visible alarming information. With its flexible user interface, the user can quickly and conveniently configure the Navigation Bar for multiple displays; each shape can be tied to a globally-available configuration file.
  • New and Improved QuickHourlys and QuickTrends - QuickHourly provides a tabular view of the process variable, setpoint and output over a quickly selectable time range. QuickTrend provides a graphical view of the process variable, setpoint and output that automatically calls up the operating range for that variable. Operating ranges are synced to the display deviation bar as well as Process Boundary Limits database. QuickHourly and QuickTrend can be called up on demand by the operator or docked into an IDv3 tabbed window that will update to display the currently selected point. 
  • Embedded Trend Shape - A compact version of the Standalone Trend, this shape provides live data, historical data, alarming information, and visual representation of desired operating ranges of multiple configured points within any display. The shapes also provide visual alarming on the traces themselves, and can be dynamically shown/hidden as needed. A timeout feature ensures that hidden traces are re-enabled after a configurable period of time.

Product Benefits

The Interface Dynamics library is continually improving with new features and enhancements and tested against control system releases – ProSys has supported our display libraries from the creation of our subpicture library for Native Window to ProControls for GUS through Interface Dynamics v3 for Experion. Other benefits include:

  • Flexibility – powerful displays allow a user to adjust the view according to their needs
  • Consistency – objects used to represent data have a common look and feel, regardless of the system type
  • Ease of maintenance – template displays and documentation to facilitate maintenance of existing displays and creation of new ones
  • Trending capabilities – display historical information for a single point (quick trend) or multiple points (full trend)

Unique Product Features

  • One display library – convert shapes from any library to Interface Dynamic shapes with the click of a button, saving thousands of dollars. This also allows for ease of upgrades 
  • One online style guide
  • Direct entry – allows for easier entry of data, reduces changes in operators focus, reduces chance of errors, encourages operator response and reduces operator loading times
  • Advanced trending – ability to make a trend with any process and features drag and drop functionalities
