Why Profiles

PROFIBUS installations are inhomogeneousDifferent ApplicationsDifferent DevicesDifferent Manufacturers

All PROFIBUS devices need to have a sub-set of common functionalities

This sub-set is called Profile

Why Profiles4

PA Profile 3.02

Application profiles areUnifiedVendor-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 PI17 different profiles are existing currently

Profile GSDMaintained by PIBasic device description

Advantage:No need for specific GSDDevices can be changed regardless of device version (device replacement is easy)

Disadvantage:Specific device features are not accessibleFull potential of devices is not reached

Manufacturer GSDMaintained by the manufacturerDetailed device description

Advantage:Full potential of the device is unlocked (diagnostics, all supported PV…)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!

Clear Diagnostic messages!

Easy device replacement!

Faster Up/Download!

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
