With PROFINET is PROFIBUS DP/PA still relevant?
Coupler / Link
PROFIBUS-DP
PROFIBUS PA
Proxy
PROFINET
PROFIBUS PA
In the long view PROFIBUS DP will be replaced by PROFINET in new projects
PROFINET will become the backbone of PROFIBUS PA
PROFIBUS PA will grow due to its unique strengths in process industries
bus powering of devices
distance – 1900m safe area
designed for use in explosion/hazardous areas - easy application
PA Profile for easy life-cycle management
