Grafchart for Industrial Automation
Researchers: Alfred Theorin, Charlotta Johnsson
Funding: LCCC
Grafchart has proven to be a very capable and suitable language for various control applications on both local and on supervisory level as well as for all levels of automation. It also has potential for formal descriptions, validation, and analysis. It has been used with for a wide variety of applications, e.g. batch control, discrete control, and diagnosis and the paradigm fits all of these very well.
Project aims:
- To evaluate the advantages and disadvantages of using Grafchart for industrial applications compared to the languages used today
- To improve the state of art of Grafchart
The research in this project primarily focuses on aspects that are considered important and useful for the industry. In particular the current focus is on the following topics:
- Add SOA support for Grafchart, and evaluate it in real setups. The SOA paradigm is promising approach to deal with the currently increasing complexity, increasing requirements on flexibility, and increasing demand for vertical integration.
- Real-time execution of Grafchart applications. This also enables exploring how to handle e.g. reconfiguration of running applications. Reconfiguration is taken for granted in the automation world but is rather unexplored from a research point of view.
- Improved object orientation support for Grafchart. Analyse various constructs of other modern programming languages, check if they are possible to add to Grafchart, and evaluate the benefits of adding them.
