scope:

This document provides information, and recommended minimum requirements related to embedded software supporting the main functions of switchgear and controlgear during the whole lifecycle of the equipment. It includes also the parameterization aspects and basics about secure coding standards.

This document can be used in addition to product standard requirements when not already covered.

This document is appropriate for new development or major changes in existing equipment.

This document is not intended to cover the functional safety of control systems for machinery or for automation which are covered by IEC 62061, ISO 13849-1 and IEC 61508 (all parts) , neither the cybersecurity risk which are covered by ISO 27005, and IEC 62443 (all parts). It gives only some example of secure coding rules.

NOTE Future new publication IEC TS 63208¹ is under development for implementing embedded cybersecurity measures within switchgear and controlgear based on ISO 27005 and IEC 62443 (all parts).
