Definition of a Profile

Types of Profiles
There are 3 types of profile:
Communication profiles

Functional profiles

Application profiles

Communication Profile
A communication profile describes the characteristics of a bus or network:
Cables

Connectors

Electrical characteristics

Access protocol

Addressing system

Periodic exchange service

Messaging service

...

A communication profile is unique to a type of fieldbus (such as Modbus, PROFIBUS DP, and so on) and
is used by different types of devices.
Functional Profile
A functional profile describes the behavior of a type of device:
Functions

Parameters (such as name, format, unit, type, and so on.)

Periodic I/O variables

State chart

...

A functional profile is common to all members of a device family (such as variable speed drives, encoders,
I/O modules, displays, and so on).
They can feature common or similar parts. The standardized (IEC 61800-7) functional profiles of variable
speed drives are:
CiA402

PROFIDRIVE

CIP AC Drive

CiA402 device profile for drives and motion control represents the next stage of this standard development
and is now part of the IEC 61800-7 standard.
Application Profile
Application profile defines the services to be provided by the devices on a machine. For example, CiA DSP
417-2 V 1.01 part 2: CANopen application profile for lift control systems - virtual device definitions.
Interchangeability
The aim of communication and functional profiles is to achieve interchangeability of the devices connected
via the fieldbus.
