Industrial-process measurement, control and automation. Evaluation of system properties for the purpose of system assessment-Terminology and basic concepts
工业过程测量、控制和自动化 为系统评估目的对系统性能进行评估
BS EN 61069-1:2016 defines the terminology and outlines basic concepts in the assessment
of a basic process control system (BPCS) and a basic discrete control system (BDCS). These
two general system types cover the areas of discrete, batch and continuous applications. In
IEC 61069 these two, BPCS and BDCS, together are referred to as "basic control system(s)",
(BCS).The treatment of safety in IEC 61069 is confined to hazards that can be present within the
BCS itself.Considerations of hazards that can be introduced by the process or equipment under control,
of the BCS to be assessed, are excluded.Where the BCS risk reduction is intended to be less than 10 (i.e. SIL < 1, per IEC 61508-4),
then assessment comes under IEC 61069.A BCS with a safety integrity level (SIL) or performing any safety instrumented function (SIF)
is not covered by IEC 61069, where SIL is defined by IEC 61508-4 and SIF is defined by
IEC 61511-1.This part of IEC 61069 is intended for the users and manufacturers of systems, and also for
those who are responsible for carrying out assessments as an independent party.Cross References:IEC 61000-4-2IEC 61000-6-4:2006IEC 61000-6-4:2006/AMD1:2010IEC 61508-4:2010IEC 61511-1:2003EN 61000-4-2EN 61000-6-4:2007EN 61000-6-4:2007/A1:2011EN 61508-4:2010EN 61511-1:2004IEC 61069IEC/TS 62603-1IEC 61800-7-1:2015IEC 61987-1:2006IEC 61508-1:2010IEC 82045-1:2001IEC 60300-3-1IEC 60654IEC 60654-1IEC 60654-2IEC 60654-3IEC 60654-4IEC 60038IEC 60721-3-1IEC 60721-3-2IEC 60721-3-3IEC 60721-3-4IEC 61326-1:2012IEC 61000-4-3IEC 61000-4-4IEC 61000-4-5EN 61069CLC/TS 62603-1EN 61800-7-1:2016EN 61987-1:2007EN 61508-1:2010EN 82045-1:2001EN 60300-3-1EN 60654EN 60654-1EN 60654-2EN 60654-3EN 60654-4EN 60038EN 60721-3-1EN 60721-3-2EN 60721-3-3EN 60721-3-4EN 61326-1:2013EN 61000-4-3EN 61000-4-4EN 61000-4-5IEC 61000-4-6IEC 61000-4-8IEC 61000-4-9IEC 61000-4-10IEC 61000-4-11IEC 61000-2-4ISO 9001:2015IEC 60664-1IEC 61010-1IEC 62381IEC 62443EN 61000-4-6EN 61000-4-8EN 61000-4-9EN 61000-4-10EN 61000-4-11EN 61000-2-4EN ISO 9001:2015EN 60664-1EN 61010-1EN 62381EN 62443All current amendments available at time of purchase are included with the purchase of this document.
