Industrial Safety: Embedded World 2010

What Are Safety Systems? The function of a safety system is to monitor and control conditions on a machine or process that are hazardous − Potential risks for machine operators − Potential damage to machines/goods − Potential damage to environment Systems and components must be designed such that they are safe under normal conditions Faults, failures and external influences must not result in an undetected loss of safety © 2010 Altera Corporation - Public ALTERA, ARRIA, CYCLONE, HARDCOPY, MAX, MEGACORE, NIOS, QUARTUS & STRATIX are Reg.

Designing a ‘Safe’ Machine Historically safety in industrial automation only required simple mechanical appliances or electrical switches to turn off power Today’s safety systems and new legislation require that products must be designed to ensure safety under both ‘Normal’ and ‘Fault/Failure’ conditions Developers must ‘design in’ software safety features All potential failures must be assessed and safeguards designed into the product Developers must prove that their product is safe and submit the proof for certification e.g. TÜV Rheinland © 2010 Altera Corporation - Public ALTERA, ARRIA, CYCLONE, HARDCOPY, MAX, MEGACORE, NIOS, QUARTUS & STRATIX are Reg.

TÜV Safety Certification All relevant aspects of the product are reviewed: − Safety calculations − Development flow (hardware and software) − Component devices and IP − Tools used − Product design and construction Complex safety functionality increases development time, e.g. 2 to 4 years longer © 2010 Altera Corporation - Public ALTERA, ARRIA, CYCLONE, HARDCOPY, MAX, MEGACORE, NIOS, QUARTUS & STRATIX are Reg.
