■ Overview
Communication functions
The process or field communication (PROFIBUS DP,
PROFIBUS PA) is used to link field device to an automation,
HMI or I&C system.
The connection can be established through integrated inter-
faces on the CPU or using interface modules (IMs) and commu-
nications processors (CPs).
With today's powerful automation systems it is often more effec-
tive to link several PROFIBUS DP lines to one automation system
not only in order to increase the number of connectable I/O sta-
tions but also to be able to handle individual production areas
independently of others (segmentation).
PROFIBUS is standardized according to IEC 61158/EN 50170.
It is an efficient, open and robust fieldbus system with short re-
sponse times and the following protocols:
• PROFIBUS DP
(Distributed Peripherals) is used to connect distributed pe-
ripherals, e.g. SIMATIC ET 200 with very fast response times
according to the IEC 61158/EN 50170 standard.
• PROFIBUS PA
(Process Automation) expands PROFIBUS DP with inherently
safe transmission according to the international standard
IEC 61158-2.
