1 Scope
This part of IEC 61784 defines a set of protocol specific communication profiles based primarily on the
IEC 61158 series, to be used in the design of devices involved in communications in factory
manufacturing and process control.
Each profile selects specifications for the communications protocol stack at a device.
It contains a minimal set of required services at the application layer and specification
of options in intermediate layers defined through references. If no application layer
is included, then a minimal set of required services at the Data-link layer is specified.
The appropriate references to the protocol specific types are given in each communication
profile family or associated profiles.
NOTE All profiles are based on standards or draft standards or International Standards published by the IEC or from 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 and
protocols from the total available set that is defined and modeled in IEC 61158. For the selected subset of services and protocols, the profile also describes any
possible or necessary constrains in parameter values.
Table 1 shows the communication profile families that are defined in this standard.

NOTE 2 CP 1/1 has a denigrated PhL device profile subclass, which uses a variant of a Type 3 PhL.
NOTE 3 CP 3/2 has a denigrated PhL device profile subclass, which uses a variant of a Type 1 PhL.
