Operator Station Server Load Restriction for Safe Configuration Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In technical plants, unsynchronized loading of automation data between operators and project planners at different locations can lead to loss of control, potential damage to the plant, and risks of server overload during data processing.
Innovation Solution
The operator station server is configured to refuse receipt or processing of automation configurations for a specific period if an abort condition is present, such as server overload, to prevent disruptions and maintain high availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operator station server continuously receives and processes automation configurations, then the system maintains high productivity and responsiveness, but the server may become overloaded leading to system failures and loss of control
Solution Approach 1:
The invention applies preliminary anti-action by detecting abort conditions (such as operator activities like error handling or critical optimizations) before they lead to system failure, and proactively restricting automation configuration loading to prevent server overload and maintain system reliability
Solution Approach 2:
The system dynamically adjusts its behavior by monitoring server load and operator activities in real-time, temporarily restricting automation configuration loading when abort conditions are detected, and automatically resuming normal operations when the server is ready, thus adapting productivity and reliability based on current system state
2Ease of operation
If operators and project planners work independently at different locations, then the system provides operational flexibility and ease of use, but unsynchronized loading of automation data can lead to loss of control and potential plant damage
Solution Approach 1:
The invention implements feedback mechanisms where the operator station server monitors operator activities and communicates abort conditions back to the engineering station server, ensuring that automation configuration loading is synchronized with current operational status, thus maintaining control safety while allowing distributed work
Solution Approach 2:
The system performs preliminary actions by checking for abort conditions and notifying the engineering station server before allowing automation configuration loading, preventing unsynchronized changes that could lead to loss of control while maintaining the flexibility of distributed operations

AI summary
A control system for a technical plant, in particular a process or production plant, includes an operator station server and an engineering station server, wherein the engineering station server includes a computer-implemented design tool via which an automation configuration for an automation of the technical plant can be created, and wherein the engineering station server transmits the automation configuration for operating and monitoring the technical plant to the operator station server, where operator station server of the control system refuses, for a specific period of time, receipt or processing of the automation configuration for the operation and monitoring of the technical plant if an abort condition is present.
