What is BS EN 61784-3-2 – Functional safety fieldbus about?

BS EN 61784-3-2 is a part of the IEC 61784 multi-series that discusses industrial communication networks. BS EN 61784-3-2 specifies a safety communication layer (services and protocol) based on CPF 2 of IEC 61784-1 , IEC 61784-2 and IEC 61158 Type 2. BS EN 61784-3-2 identifies the principles for functional safety communications defined in IEC 61784-3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only. BS EN 61784-3-2 defines mechanisms for the transmission of safety-relevant messages among participants within a distributed network using fieldbus technology in accordance with the requirements of IEC 61508 series for functional safety. These mecha...
