Tiivistelmä
This research has been done for a company that specialises in control system hardware and software for mobile heavy machinery. The company has identified an increasing demand for safety certified PLCs (programmable logic controllers) and therefore wants to develop a new CAN (controller area network) bus controller that can be safety certified to PL d (performance level d) in accordance with the EN ISO 13849-1:2015 standard. The company has years of experience in control system hardware and software development but no experience in developing safety certified products. Therefore, the company wants to gain more knowledge about the safety certification requirements for the new CAN bus controller and develop their PLM (product lifecycle management) of safety certified products.
This research consists of a PL d safety certification requirement specification for the new CAN bus controller and a PLM requirement specification for safety certified products. The research methods used in this work are a literature review and interviews with company employees and a certification expert. Information for this work was also gained from a certification offer from a certification body.
The CAN bus controller must comply with requirements from several standards of which the company already has lots of experience. Therefore, the scope of the safety certification requirement specification was limited to the most relevant standard EN ISO 13849-1:2015. The requirement specification was done by analysing relevant standards, literature, and the certification offer received from the certification body. Insights to the research topic were also gained through interviews with company employees and a certification expert. As a result, a list of requirements and recommendations was created for the safety certification of the new CAN bus controller.
PLM is a very broad topic that can cover almost all activities in a company. Therefore, the scope of the PLM requirement specification was limited to focus on safety certified products. The requirement specification was done by analysing relevant standards, literature, and the findings of the safety certification requirement specification. Insights to the research topic were also gained through interviews with company employees and a certification expert. As a result, a list of requirements and recommendations was created for developing the PLM of safety certified products in the company.
The results of this research provide lists of requirements and recommendations for the safety certification of the CAN bus controller and for the development of the company’s PLM for safety certified products. The research also provides knowledge to the company about literature relevant for the research topics. Recommendations for follow-up actions for the company are also presented based on the results of this research.
