Operator Selection Reannotation for Persistent Plant Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for technical installations, such as production and process systems, limit user selections created during runtime to a single operator and do not allow easy transfer between projects, making efficient operation and monitoring cumbersome, especially when process objects are moved or deleted.
Innovation Solution
A control system comprising an operator station server, client, and engineering station server, where the operator station client generates and adapts graphical presentations, and the operator station server stores and transmits adjustments to both the operator and engineering station servers, enabling persistence and sharing of user selections across the technical installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user selections are created and optimized during runtime by operators, then operation and monitoring efficiency is improved, but the selections are limited to a single operator and cannot be transferred between projects
Solution Approach 1:
The patent implements a database that stores user selections in a project-independent manner, allowing the same selections to be universally applied across multiple operators and different projects. The system enables loading and saving of user selections between runtime and engineering phases, making the selections adaptable and transferable throughout the system lifecycle.
2Adaptability or versatility
If user selections are created during runtime, then operational flexibility is improved, but the selections are not persistent and require costly care and maintenance when process objects are moved or deleted
Solution Approach 1:
The patent enables user selections created during runtime to be saved to a database before engineering changes occur. When process objects are moved or deleted in engineering, the stored selections can be reloaded and automatically updated, preventing data loss and eliminating the need for costly manual maintenance of operational selections.
3Device complexity
If user selections are maintained only in runtime memory, then system complexity is reduced, but the selections are lost when runtime ends and cannot be reused
Solution Approach 1:
The patent implements a database storage mechanism that creates persistent copies of user selections between runtime and engineering phases. selections can be saved from runtime to the database and loaded back when needed, allowing operators to reuse optimized displays without recreating them, thus eliminating time loss while maintaining manageable system complexity.
