ICS Code (Industrial process measurement and control): 25.040.40
scope:

This part of IEC 61069 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.
