PLC Configuration Workflow for Complex Device Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PLC configuration methods are inadequate for managing and configuring complex PLC devices, particularly sensors and actuators, as they require intuitive graphical interfaces that go beyond simple parameter settings, and existing systems lack efficient methods for distributing and reusing configuration information across multiple similar systems.
Innovation Solution
A method involving a first graphical user interface tailored to generate configuration information for PLC devices, which is then transferred to a second application for controlling the PLC central unit, allowing configuration information to be distributed and reused efficiently, without requiring a direct connection between the first application and the PLC device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a generic parameter-based interface is used for PLC configuration, then the system is simple to implement, but it cannot handle complex PLC devices with coordinated graphical user interfaces
Solution Approach 1:
The configuration system is segmented into two distinct applications: a first application for generating configuration information with device-specific graphical interfaces, and a second application for transferring and executing configuration on the PLC central unit. This segmentation allows each application to specialize in specific tasks, enabling support for complex devices without overwhelming system complexity.
Solution Approach 2:
Configuration information serves as an intermediary data structure that bridges the first application (with device-specific GUIs) and the second application (for PLC control). The configuration information is generated in the first application, transferred to the second application, and then executed on the PLC central unit, enabling complex device configuration without requiring the PLC control application to have device-specific interfaces.
2Productivity
If configuration information is generated directly for each PLC device individually, then device-specific configuration is precise, but distribution to multiple similar systems becomes inefficient
Solution Approach 1:
The system enables copying of configuration information between similar PLC devices. The first application generates configuration information that can be stored and reused. When configuring similar devices, the configuration can be copied from one device to another, significantly improving productivity when deploying multiple identical or similar systems while maintaining ease of operation through template-based reusability.
3Manufacturing precision
If a direct connection between the configuration application and PLC device is required, then configuration accuracy is high, but system complexity and connection requirements increase
Solution Approach 1:
The PLC central unit acts as an intermediary between the configuration applications and the PLC devices. The first application generates configuration information, which is transferred to the second application, and then the second application communicates with the PLC central unit to execute the configuration on connected devices. This intermediary approach maintains configuration accuracy while reducing connection complexity, as applications only need to communicate with the PLC central unit rather than establishing direct connections to each device.

AI summary
A method for configuring a PLC device (3), wherein a first application (10) with a first graphical user interface (11) is executed. At least one user input is captured on the first graphical user interface (11). Subsequently, configuration information (15) with at least one configuration parameter (14) for the at least one PLC device (3) is generated based on the captured user input. A second application (16) with a second graphical user interface (17) is then executed. The configuration information (15) is then transferred from the first application (10) to the second graphical user interface (14) of the second application (16). Finally, PLC configuration information is generated by the second application (16) based on the configuration information (15).The PLC configuration information is then transmitted by the PLC central unit (2) to at least one PLC device (3). Finally, the PLC device (3) loads the received PLC configuration information.
