Trainings

Inhouse-Training

The objective of our inhouse-trainings is to give engineers a fundamental knowledge of functional safety. These trainings are performed at the location of the client's company in groups of approx. 15 participants. This allows us to focus on the specific problems of your company and ensures intensive interaction and discussions. Our experts pass on their knowledge and experience. Our inhouse-trainings are an essential part of our consulting and testing services and support a successful solution to the customer's functional safety problem.

Safety Related Systems

General:
The training consists of a two day course and can have up to 15 participants.
The following content is a suggestion.
Any alterations and additions can be included in the program.

1. Introduction

• Functional safety of electrical, electronic and programmable systems
• Approval and certification procedure
• Examples of some application areas of "safety related systems"

2. General Considerations

• Overview of relevant standards
     - Generic standards
     - Application dependant standards
     - Technology dependant standards
     - EU-directives, international standards
     - Comparison of the different standards

3. Safety Philosophy

• Risk definition, risk reduction
• Introduction of different risk classes
     - Requirement class
     - Safety class

• Design, Development and production phase
     - System (safety) requirement specification
     - Validation & verification plan
     - Contents and examples
• Selection of necessary measures with consideration of the influence by the application (process) and programmable system during the design, development and production process
• Examples
     - HW-design and verification
     - SW-design and verification
• Conditions for the phases
     - Setting into operation
     - Operation

6. Safety Related Bus Systems

• Application of the IEC 61508, VDE 0801, EN 954 and EN 50159 methods and measures to bus-systems
• Principles for the use of bus systems
• Deterministic approach
     - Transmission errors, hardware failure (random), systematic failure
• Probabilistic approach to achieve a certain amount of data integrity
     - Reliability of data transmission
     - Bit error probability
     - Error probability and error detection
• Different bus architectures
• Examples

Additional requirements by the customer can be agreed upon.

Date of Training

Can be determined individually, but a preparation time of four weeks has to be considered.
