Sauer-Danfoss Launches Software PDLP Development Process

Sauer-Danfoss introduced the Software PDLP development process, a TÜV-Nord-certified “Trusted Process” that simplifies functional safety software project management, in anticipation of Bauma 2013 in Munich. Sauer-Danfoss is the first company to achieve this TÜV-Nord certification of process quality.

By providing a guided workflow, the Software PDLP process dramatically reduces time and cost associated with creating safe and certifiable software for mobile machines, enabling development teams to focus on their technical solution. The pre-certified structured process reduces waste by eliminating the need for repeated reviews of hundreds of pages of documents to follow different functional safety standards. It also reduces complexity by providing a starting point and guiding the user into the software-relevant aspects of functional-safety-related software.

Sauer-Danfoss also announced three upcoming functional safety-training modules:

Safety-Related Software Development (available in June 2013)
Risk Assessment & Safety-Function Evaluation (available in July 2013)
Functional Safety Fundamentals (available in September 2013)

Software developers with experience in the industry-proven Sauer-Danfoss PLUS+1 GUIDE graphical programming environment can learn how to utilize the Software PDLP process in the Safety-Related Software Development course.

Sauer-Danfoss recommends sequential participation in the Functional Safety Fundamentals, Risk Assessment & Safety-Function Evaluation and Safety-Related Software Development workshops. Each of the two-day training modules will be instructor-led by Sauer-Danfoss functional safety experts and available in Sweden, Germany, Denmark and the United States.

Summaries of the Sauer-Danfoss Functional Safety Training modules are as follows:

Functional Safety Fundamentals
The Functional Safety Fundamentals course offers anyone working in the area of mobile machinery an introduction to basic concepts of functional safety standards. Focused on Type-A, -B and -C standards for hydraulic/electrohydraulic systems, the course will help the user identify and select the appropriate generic or application-specific standard.

Participants will be introduced to different functional safety lifecycle models and receive an overview of the main challenges, most important process steps and critical deliverables of these models. Examples of hydraulic/electrohydraulic safety functions will also be discussed.

Upon successful completion of the workshop, trainees will have the capability to:

Select relevant functional safety standards for their area of applications
Contribute with functional safety aspects in machine design
Understand the importance of following different standards
Interpret functional safety aspects as an integral part of the organization and processes

Risk Assessment & Safety-Function Evaluation
The Risk Assessment & Safety-Function Evaluation training module will introduce risk assessment of mobile machinery and the evaluation of safety functions using the SISTEMA software tool. The focus of the course will be risk assessment and risk reduction principles in accordance with the basic safety standard EN ISO 12100:2010 and ISO 14121-2. Participants will get an in-depth view of how Sauer-Danfoss products can contribute to functional safety on mobile machinery.

SISTEMA, a software tool from the German Institute IFA, provides developers and testers of safety-related machine control systems comprehensive support in the evaluation of safety functions, in the context of EN ISO 13849-1.

Following the course, participants will be able to:

Understand the theory of risk assessment and risk reduction in accordance with EN ISO 12100:2010
Perform risk estimation in accordance with one of the methods from ISO 14121-2
Contribute to the risk assessment and reduction process
Identify safety functions as part of risk reduction
Understand how to determine the required Performance Level for safety functions
Understand the structure and functions of the SISTEMA tool
Understand and prepare safety block diagram
Create evaluations of simple safety-related machine controls, in accordance with EN ISO 13849, using the SISTEMA tool

Safety-Related Software Development
The goal of this training module is to simplify the functional safety aspects of software development in projects using Sauer-Danfoss products, tools and processes. In addition to introducing the Software PDLP development process, the training will cover how to use Sauer-Danfoss PLUS+1 safety controllers in a functional safety project and new safety-related features in the PLUS+1 GUIDE graphical programming environment.

After finishing this training, participants will be able to:

Realize the need of a structured development process like the Sauer-Danfoss Software PDLP process
Understand how to use the Sauer-Danfoss Software PDLP process in a functional safety project
Be able to contribute in functional safety software development activities
Apply Sauer-Danfoss PLUS+1 tools and products in a safe way
