Industrial networks. Single-drop digital communication interface. Functional safety extensions | Status: Current
description
1 Scope
This part of IEC 61139 specifies the extensions to SDCI in IEC 61131‑9 for functional safety. This comprises:
- • a standardized OSSDe interface for redundant switching signals based on IEC 61131‑2,
- • minor modifications/extensions to state machines of SDCI to support the safety operations,
- • a lean functional safety communication protocol on top of the standard SDCI communication which is a black channel according to IEC 61784‑3:2021,
- • protocol management functions for configuration, parameterization, and commissioning,
- • IODD extensions for functional safety,
- • a Device tool interface to support Dedicated Tools according to functional safety standards.
- • communication interfaces or systems including multi-point or multi-drop linkages,
- • communication interfaces or systems including multi-channel or encrypted linkages,
- • wireless communication interfaces or systems,
- • integration of SDCI-FS into upper-level systems such as fieldbuses/FSCPs.
