Industrial communication networks. Profiles. Assessment guideline for safety devices using IEC 61784-3 functional safety communication profiles (FSCPs). | Status: Current

1 Scope This Technical Report provides information about the assessment aspects of safe communication such as test beds, proof of increased interference immunity (EMC for functional safety), electrical safety, and other environmental requirements. This document is only applicable to safety devices for functional safety communication which are developed according to IEC 61508 and IEC 61784‑3.

NOTE This document does not cover the more complex aspects of preserving existing devices and applications in the field and migration from safety rules before IEC 61508.

The scope covers general industrial environments such as defined in IEC 61131‑2 or IEC 61000‑6‑2 and process automation environments such as those covered in the IEC 61326 series. Reference is made to the ERS (Equipment Requirements Specification) and/or SRS (Safety Requirements Specification) of a particular safety application to verify the necessary immunity of devices and systems according to IEC 61508.
