Industrial communication networks. Profiles - Functional safety fieldbuses. Additional specifications for CPF 21 Scope This part of the IEC 617843 series specifies a safety communication layer (services and protocol) based on CPF 2 of IEC 617841, IEC 617842 and IEC 61158 Type 2. It identifies the principles for functional safety communications defined in IEC 617843 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only. NOTE 1 It does not cover electrical safety and intrinsic
