Profinet
Profinet is a communication protocol for industrial automation technology based on Ethernet. Profinet uses the basic functional model of Profibus which allows smooth change-over to the new technology for Profibus users. Profinet combines the advantages of a known fieldbus system and Industrial Ethernet.
Profinet has the following characteristics:
- Real-time communication is based on modified Ethernet frames
- High performance (cycle times ranging from 1 – 8 ms, jitter up to <1µs, high throughput)
- Hard real-time communication (RT) apart from acyclic (non RT) data exchange for configuration and diagnostics
- Simple commissioning by automatic address assignment & detection of conflicting addresses
- Automatic topology identification allows for
- easy device exchange without reconfiguration
- offline planning and programming of network topology - Integral redundancy concepts for transmission paths (ring) and DCS (system redundancy)
AUMA actuators with Profinet support the entire functional scope of AC .2 actuator controls, allowing easy and flexible integration into virtually any type of network.

Functions
- Switched Ethernet with flexible priority flow control
- Data exchange in compliance with provider consumer model:
An I/O device provides the process data to one or several I/O controllers (consumers) - Cyclic real-time data via Ethernet/MAC address with priority flow control
- Acyclic communication and diagnostics via IP protocol
- Device classes:
I/O controller (PLC/DCS)
I/O devices (field devices)
I/O supervisor (programming, diagnostics, commissioning) - Simple participant identification via device name
- Identification of conflicting addresses via ACD
- Communication/routing across network segments requires specific gateway
- Guaranteed Profinet device performance defined by conformity classes A – C
(cycle times: A: 100 ms, B: 10ms, C: <1ms)

Commissioning & communication
AUMA actuators with Profinet interface integrate smoothly into network infrastructures and can be identified and addressed from any place by means of their device name or their IP address – similar to the PCs within a local network.
Just few steps are required to integrate an AUMA actuator into a Profinet environment. To this end, a standardised device description (GSDML file) is linked to the DCS. The system tools of the DCS identify and assign a name to the actuator. This name allows device identification within the Profinet system. The IP address is automatically assigned.
