Glossary
PROFIBUS
Process Field BUS: a process and field bus protocol defined in the PROFIBUS standard
IEC 61784 1:2002 Ed1 CP 3/1. This standard specifies the operational, electrical and
mechanical properties of a bit-serial field bus system.
PROFIBUS is a bus system that connects PROFIBUS compatible automation systems and field
devices on a cell and field level. PROFIBUS is available with the following protocols: DP
(= Dezentrale Peripherie, distributed IO devices), FMS (= fieldbus message specification) or TF
(= technological functions).
PROFIBUS address
Each bus node must receive a PROFIBUS address to identify it uniquely on the PROFIBUS DP.
PC / PD or the ET 200 Handheld have the PROFIBUS address "0".
DP masters and DP slaves use a PROFIBUS address in the range between 1 and 125.
PROFIBUS DP
PROFIBUS bus system with DP protocol. DP is the abbreviation of the German term 'dezentrale
Peripherie' (distributed I/O). The ET 200 distributed I/O system is based on standard
IEC 61784-1:2002 Ed1 CP 3/1.
PROFIBUS International
Technical committee dedicated to the definition and development of the PROFIBUS and
PROFINET standard.
Also known as the PROFIBUS User Organization membership corporation (PNO.)

PROFINET
Within the framework of Totally Integrated Automation (TIA), PROFINET represents a
consistent enhancement of:
PROFIBUS DP, the established field bus, and
• Industrial Ethernet, the communications bus for the cell level.
• Experience gained from both systems was and is being integrated into PROFINET.
PROFINET is an Ethernet-based automation standard of PROFIBUS International (previously
PROFIBUS Users Organization e.V.), and defines a multi-vendor communication, automation,
and engineering model. PROFINET has been part of the standard IEC 61158 since 2003.
