Programmable Display Screen Data Group Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing programmable display devices face challenges in managing multiple screens for various products within a single production line, leading to complex screen management and memory capacity issues, with current methods requiring time-consuming file transfers for line changes.
Innovation Solution
The programmable display device implements a selection information forming section and a screen data group setting section to select and manage screen data groups, allowing for the dispersion of screen data groups across internal and external storage, enabling each product to have its corresponding screen data groups without needing a single project file to include all products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single project file includes screens for all products to handle variety, then adaptability is improved, but device complexity and memory usage increase
Solution Approach 1:
The patent divides the project file into multiple screen groups, where each screen group contains screens for a specific product. This segmentation allows the system to handle multiple products by selecting appropriate screen groups, reducing the complexity of managing all screens within a single monolithic project file while maintaining the ability to adapt to various products.
2Adaptability or versatility
If a single project file includes screens for all products, then adaptability is improved, but memory capacity is consumed
Solution Approach 1:
By segmenting the project file into multiple screen groups stored in external storage media, the patent reduces the memory capacity requirement of the programmable display device. Each screen group can be loaded only when needed, rather than keeping all screens for all products in internal memory simultaneously.
Solution Approach 2:
The patent moves screen groups from internal memory to external storage media, utilizing an additional storage dimension. This allows the system to access screens for multiple products without consuming internal memory capacity, as screen groups can be loaded from external storage when required.
3Reliability
If project files are transferred for each production line switch, then screen data availability is improved, but time consumption increases
Solution Approach 1:
The patent performs preliminary actions by pre-organizing screens into screen groups corresponding to different products and storing them in external storage media. When a production line switch is required, the system simply selects and loads the corresponding screen group, avoiding the time-consuming process of transferring entire project files while ensuring screen data availability.

AI summary
A programmable display device selects and displays one screen data item from one of screen data groups each constituted of a plurality of screen data items indicative of control conditions. Further, the programmable display device includes a selection information forming section and a screen data group setting section. The selection information forming section is included in a project setting processing section, and based on screen data group information concerning the screen data groups, forms selection information by which one of the screen data groups is selected. The screen data group setting section is included in the project setting processing section, and sets, as a screen data group to be used, the one of the screen data groups which is selected based on the selection information.
