NOTE4 For safety-related embedded software for components with PlL = e, see IEC 61508-3:1998,Clause 7.Ģ.Normative references:The following documents, in whole or in part, are normatively referenced in this document and areindispensable for its application. NOTE3 The requirements provided in this part of lSo 13849 for programmable electronic systems arecompatible with the methodoiogy for the design and development of safety-related electrical, electronic andprogrammable electronic control systems for machinery given in lEC 62061.
NOTE2 For the definition of required performance level, see 3.1.24. NOTE1 Examples of products which are parts of SRP/CS: relays, solenoid valves, position switches,PLCS,motor control units, two-hand control devices, pressure sensitive equipment.For the design of such products,it is important to refer to the specifically applicable International Standards, e.g. Lt does not give specific requirements for the design of products which are parts ofSRP/CS.Nevertheless,the principles given, such as categories or performance levels, can be used. Lt does not specify the safety functions or performance levels that are to be used in a particular case.This part of lSo 13849 provides specific requirements for SRP/CS using programmable electronicsystem(s). it applies to SRP/CS for high demand and continuous mode, regardless ofthe type of technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.), for all kindsof machinery.
