Overview
• Bus system
- For process and field communication in cell networks with
few stations and with field devices
- For data communication according to IEC 61158/EN 50170
• Provides openness for connecting standard-conform compo-
nents from different manufacturers
- PROFIBUS – the fieldbus standard in production and
process automation comprises:
- Defining of standards for physical bus characteristics and
access control
- Defining of the user protocol and the user interface
• Process or field communication
- PROFIBUS DP for fast, cyclic data exchange with field
devices
- PROFIBUS PA for applications in process automation and in
the inherently safe area
• Data communication
- PROFIBUS FMS for data communication between automa-
tion devices from different manufacturers
PROFIBUS within the automation pyramid

Benefits
• PROFIBUS is an efficient, open and robust bus system which
guarantees smooth communication.
• The system is fully standardized, thus enabling standard-
conform components from different manufacturers to be con-
nected without problem.
• Configuring, commissioning and troubleshooting can be per-
formed from any position. This means that the freely select-
able communication relationships are very flexible, easy to
implement and simple to change
• Fast local assembly and commissioning using the
FastConnect cabling system.
• Constant monitoring of the network components by means
of a simple and effective signaling concept.
• High protection for your investment because existing systems
can be expanded without repercussions.
• High availability thanks to ring redundance with OLM.
