IEC 61784-1-2019 pdf free.Industrial communication networks – Profiles – Part 1:Fieldbus profiles.
This part of IEC 61784 defines a set of protocol specific communication profiles basedprimarily on the IEC 61158 series,to be used in the design of devices involved incommunications in factory manufacturing and process control.
Each profile selects specifications for the communications protocol stack at a device. Itcontains a minimal set of required services at the application layer and specification ofoptions in intermediate layers defined through references. lf no application layer is included,then a minimal set of required services at the Data-link layer is specified. The appropriatereferences to the protocol specific types are given in each communication profile family orassociated profiles.
NOTE All profiles are based on standards or draft standards or International Standards published by the lEC orfrom standards or International Standards established by other standards bodies or open standards processes.The structure of communication profile families is specified in Figure 1.
Each profile selects an appropriate consistent and compatible subset of services andprotocols from the total available set that is defined and modelled in lEC 61158.For theselected subset of services and protocols,the profile also describes any possible ornecessary constraints in parameter values.
Table 1 shows the communication profile families that are defined in this standard.
