Operator Terminal Display Layout for Alarm-Driven Screen Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing process control systems require significant engineering time to pre-configure for various scenarios, leading to inefficient display element management during alarms or events, causing operator inconvenience and time loss.
Innovation Solution
A display element handling device and method that dynamically adjusts display elements on an operator terminal based on received alarms or events, utilizing machine learning to prioritize and update display combinations, incorporating AI/ML algorithms to learn operator habits and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If pre-configuration is used to prepare display elements for specific alarms or events, then the system can react automatically to alarms/events, but it requires a big amount of time for engineering and can cover only partially the possible scenarios
Solution Approach 1:
The display element combination changes dynamically based on the current situation and operator selections rather than being statically pre-configured. The system adapts the display configuration in real-time according to the alarm type and operator choices, eliminating the need for extensive pre-engineering of all possible scenarios.
Solution Approach 2:
The system automatically determines and presents situation handling display element combinations without requiring manual pre-configuration for each scenario. The processor autonomously selects appropriate display elements based on the alarm received and operator preferences, making the system self-configuring rather than requiring external engineering effort.
2Ease of operation
If the operator returns to the task after handling the alarm or event, then the operator can continue the original work, but the display elements needed for the task may no longer be available
Solution Approach 1:
The system preserves the current display element combination information and uses it as a basis for determining situation handling display element combinations. When the operator returns to the task, the system can restore or maintain the original display configuration, avoiding the need for reconfiguration and ensuring display elements are available when needed.
3Loss of information
If the operator manually configures the screen to view necessary display elements, then the operator can access required information, but it is cumbersome and time consuming
Solution Approach 1:
The system automatically determines and configures the situation handling display element combination based on the received alarm and operator selections, eliminating the need for manual screen configuration. The processor autonomously selects and displays the relevant display elements, making the system self-configuring rather than requiring operator effort.
Solution Approach 2:
The system pre-determines appropriate display element combinations for different alarm situations and presents them to the operator for selection. This preliminary preparation of display configurations eliminates the need for operators to manually configure screens during time-critical alarm handling.

AI summary
A display element handling device (12; 17) for a process control system (10) receives an alarm or event from the process control system (10) when a current display element combination is displayed to a process control system operator on the operator terminal (12), which current display element combination comprises display elements selected by the process control system operator, determines a situation handling display element combination directed towards addressing the alarm or event, which situation handling display element combination comprises one or more display elements linked to the alarm or event to be displayed to the process control system operator on the operator terminal, changes, if receiving a selection from the process control system operator in relation to the situation handling display element combination, a screen of the operator terminal (12) according to the selection, and updates the situation handling display element combination.
