The document discusses PROFIBUS profiles, which define common functionalities for devices to ensure interoperability. It focuses on the PA Profile 3.02, which improves on previous versions by providing condensed diagnostic messages, automatic device identification number adaptation during replacement, and faster parameter transmission. PROFIBUS profiles help standardize behavior across different devices, applications, and manufacturers.

Why Profiles
PROFIBUS installations are inhomogeneous
Different Applications
Different Devices
Different Manufacturers
All PROFIBUS devices need to have a sub-set of
common functionalities
This sub-set is called Profile

5. Profiles
PA Profile 3.02
Application profiles are
Unified
Vendor-neutral
Definitions, to establish a common behavior
General, device exceeding behavior
(e.g. safety applications)
Special, device specific behavior
(e.g. process automation, drives)
Specific, industry dependent behavior
(e.g.: laboratory devices)
Profiles are defined by PI
17 different profiles are existing currently

Basic device description
Advantage:
No need for specific GSD
Devices can be changed
regardless of device version
(device replacement is easy)
Disadvantage:
Specific device features are not
accessible
Full potential of devices is not
reached
Manufacturer GSD

Detailed device description
Advantage:
Full potential of the device is
unlocked (diagnostics, all

Device is not a “grey box”
Disadvantage:
Correct GSD to corresponding
device is needed (device
replacement is tricky)

Market statements based on experience
“Diagnostics are very helpful!”
But: Too much (unfiltered) diagnostics
 Confusing!
“PROFIBUS offers great opportunities!”
But: Device replacement too difficult
 unwanted shutdown!
“We can access the devices via PROFIBUS!”
But: Parameter Up/Download is too slow
 Annoying!

Summary
PROFIBUS profiles ensure common behavior of
different devices in various environments
Profiles are independent from the used protocol
(e.g.: PROFIBUS, PROFINET…)
Future adaptions of existing profiles into other
communications in progress
(e.g.: PA Profile for PROFINET)
Profiles unlock the full potential of PI technologies
