4.1 Profibus Standardisation
Profibus is based on known international standards. The protocol architecture follows the
ISO/OSI layer model. Since 2000, Profibus is specified in IEC 61158 Type 3 and IEC 61784.
IEC 61158 Type 3 includes the whole range of Profibus consisting of the DP-V0, DP-V1 and
DP-V2 versions. IEC 61784 specifies the properties of the CPF 3 communication series, in
which the profiles used under Profibus are summarised.
Profibus achieved national standardisation in 1993 through DIN 19245, Part 1-3 and pan-
European standardisation in 1996 through EN 50170.
The Profibus range consists of three compatible versions (DP, PA, FMS). All three versions use
the same type of protocol for bus access. This protocol is integrated via layer 2 in the OSI refer-
ence model. It also includes data integrity and handling of the transmission protocols and tele-
grams. The 'DP' and 'FMS' versions also use the same transmission technology, which is inte-
grated via layer 1.

4.2 Profibus DP
This version is intended for high-speed data communication at device level. Central controllers
(e.g. PLCs/PCs) thus communicate with their distributed field devices (input/output units, drives,
encoders etc.) via a special serial high-speed link.
Profibus DP uses layer 1, layer 2 and the user interface. The DDLM offers the user interface
easy access to layer 2. The functions of the application are defined in this part of the interface.
Profibus DP only uses a part of the services of layer 2. These services are called via Service
Access Points (SAPs) of layer 2 through higher layers (user interface). For Profibus DP, each
SAP is allocated a precisely defined function.
