PROFINET (Process Field Network) is an Industrial Ethernet protocol. It uses TCP/IP and is real-time capable.

PROFINET IO is specially designed for communication between a controller and decentralized field devices and describes the entire data exchange between controllers (masters) and devices (slaves) as well as configuration and diagnostics. It follows the producer-consumer model.
2 transfer variants are available:

• Real-time (RT) communication
• Isochronous real-time (IRT) communication

Within PROFINET IO, process data and alarms are always transferred in real time (RT). RT communication is the basis for data exchange with PROFINET IO. Clock-synchronous data exchange with PROFINET is defined in the isochronous real-time (IRT) concept. The difference to real-time communication lies essentially in the determinism, so that the start of a bus cycle is maintained with the highest precision.

X20 modules or other modules based on X2X Link can be connected to the bus controller. Modular system configurations are optimally supported by PROFINET. Using the device description file (GSDML format), it is very easy to handle project configuration in the respective engineering tool from the manufacturer of the master device.
