  1. 1. Adapting Grafchart for Industrial Automation

    Författare :Alfred Theorin; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grafchart; JGrafchart; Graphical languages; Language Extension; Attribute Grammars; JastAdd; Flexible manufacturing systems; Agile manufacturing; SOA; DPWS; Web Services;

    Sammanfattning : Current trends in industrial automation are the need for customizable production, vertical integration, more advanced sensors and actuators, and shorter time to market. The currently used control systems and languages for control were developed with a more static production in mind. LÄS MER

  3. 2. A Sequential Control Language for Industrial Automation

    Författare :Alfred Theorin; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grafchart; service oriented architecture; event-driven architecture; flexible production systems; industry 4.0; real-time; FMI; PID;

    Sammanfattning : Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. LÄS MER

  4. 3. Exception Handling in Recipe-Based Batch Control

    Författare :Rasmus Olsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; S88; grafchart; exception handling; recipe; batch;

    Sammanfattning : The focus of this thesis is exception handling in recipe-based batch control. Exception handling is a critical element for achieving long-term success in batch production. It is reported to constitute 40-60 percent of the batch control design and implementation effort. LÄS MER

  5. 4. Recipe-Based Batch Control Using High-Level Grafchart

    Författare :Charlotta Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Batch control; Grachart;

    Sammanfattning : High-Level Grafchart is a graphical programming language for control of sequential processes. Sequential control is important in all kinds of industries: discrete, continuous and batch. Sequential elements show up both on the local control level and on the supervisory control level. LÄS MER

  7. 5. A Graphical Language for Batch Control

    Författare :Charlotta Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Batch Recipes; Batch Processes; Sequential Control; Grafcet; Petri nets; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : In this thesis a graphical language for sequential control is presented and its application to batch control is examined and discussed. The name of the language is Grafchart. Its main feature is that it makes it possible to express complicated control problems in a compact and intuitive manner. LÄS MER
