Although Factory Automation widely uses Industrial Ethernet as the main Fieldbus, in Process Automation plants PROFIBUS is still the number one communication system. Karsten will show, why this is not an issue, how users can benefit from PROFINET today and how PI keeps developing PROFINET to meet all needs and requirements of PA including a new Physical Layer (APL) for Ethernet in hazardous areas.

Process Automation networks with PROFIBUS and
PROFINET
Essential requirements in Process Automation
High availability and flexibility for changes
Availability
Continuous operation for many years
Any stop = Loss of production = High costs
Redundancy
Single failures shall not take down the process
Redundancy increases availability
Scalable redundancy through the entire system
Changes during operation
Continuous modification of plants during operation
Add new or change existing automation functions
