Any security measures described in this User Manual, for example, for user access,password security, network security, firewalls, virus protection, etc.,represent
possible steps that a user of an 800xA System may want to consider based on a
risk assessment for a particular application and installation. This risk assessment,
as well as the proper implementation, configuration, installation, operation,
administration, and maintenance of all relevant security related equipment,
software, and procedures, are the responsibility of the user of the800xA System.
This user manual provides application notes and advice for wiring and installation of
PROFIBUS networks. It is intended to be used by Instruments Engineers,
Instrument Technicians, Electricians and Installers for the wiring and associated
components for the PROFIBUS applications.
The main areas covered in this manual are:
Fieldbus topology and the redundancy concepts
Transmission technologies
Cable media and PROFIBUS components
Design of a plant and the cable laying regulations
Commissioning and testing of PROFIBUS equipment
For a list of documentation related to ABB PROFIBUS products, please see the

Section 1 Introduction gives a brief overview of the PROFIBUS protocols,
technology terms, transmission technologies and the Fieldbus Intrinsically Safe
Concept (FISCO).
Section 2 Transmission Technology provides detailed information about the
PROFIBUS physics like RS485(-IS), MBP, fibre optics as well as basics of cable
types, transmission rates, network limits and bus line length. This chapter is
intended for users, they are not familiar with the basics of the PROFIBUS
technology.
Section 3 Fieldbus Topologies describes PROFIBUS topologies, usable with certain
transmission technology, described in section 2. This chapter is intended for readers,
they know PROFIBUS basics and need an introduction to install PROFIBUS
networks in connection with the AC 800M controller and the PROFIBUS master
interface CI854(A). Also the readers get recommendations and important hints for
installation work.
Section 4 Commissioning of PROFIBUS equipment describes additional hints on
the installation of PROFIBUS networks. Furthermore this chapter provides detailed
information to find errors and how to fix them.
