  1. 1. An Integrated Tool Chain for Combinatorial Testing of Industrial Control Software

    Kandidat-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Liene Andersone; Anne Christine Carlsson; [2021]
    Nyckelord :Control Software Testing; PLC; CODESYS; Combinatorial Testing; Testing;

    Sammanfattning : Testing is an important activity in software development used to ensure the quality of a product. In industrial practice when developing control software, such as Programmable Logic Controllers (PLCs), software testing is, in some cases, neglected during the development process. LÄS MER

  3. 2. Evaluating the Next Generation of Building Automation – IoT SmartBuildings

    M1-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Robin Winroth; [2020]
    Nyckelord :;

    Sammanfattning : Abstract Building automation systems typically use proprietary hardware and included softwarefor their automation which can make the systems vendor-locked. Establishedprogramming standards limits the freedom of companies to improve their automationsystems with the growth of the IT era. LÄS MER

  4. 3. Auto-testing of code

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Flamur Breznica; [2020]
    Nyckelord :IEC-61131-3; regression testing; automation; automatic; machines; S7 Unit test; unit testing; NUnit; Siemens; TIA Portal; Simulation; SIMIT; automation production systems; digital twin; Technology and Engineering;

    Sammanfattning : The topic of this thesis is software in systems of automated machines that produce products in a company. Testing of these systems is crucial for the machines to work as intended. Usually testing is done manually, both while the system is developed and while the production is running. This is called traditional testing. LÄS MER

  5. 4. Code generation for programmable logic controllers : Evaluating model-based engineering practices in a real-world context

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Adam Johansson; Tim Johansson; [2020]
    Nyckelord :PLC; Code generation; Model-driven engineering; IEC 61131-3;

    Sammanfattning : The industrial manufacturing of today is achieved through the use of programmable logic controllers (PLC). The way PLCs are programmed remains largely unchanged since their conception 40 years ago, but complexity and software size have increased, and requirements have becomemore elaborate. LÄS MER

  7. 5. Analoghantering i Siemens Open Library : Modifiering och jämförelse

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :David Elvinsson; [2018]
    Nyckelord :PLC-programming; HMI; Siemens Open Library; Human-machine; PLC-programmering; HMI; Siemens Open Library; Människa-maskin;

    Sammanfattning : Ökade förväntningar på hållbarhet, säkerhet och ergonomi ställer krav på allt fler områden, även inom PLC-, samt HMI-programmering. Syftet med detta arbete har varit att modifiera ett analoginput-block, med tillhörande faceplate och faceplate-ikon från Siemens Open Library. LÄS MER
