4.5.10.1 General information
PROFINET (Process Field Network) is an Industrial Ethernet protocol. It uses TCP/IP and is real-time capable.
PROFINET IO was developed for real-time (RT) and synchronous communication (IRT = Isochronous Real Time).
The designations RT and IRT merely describe the real-time properties for communication taking place within
PROFINET IO. PROFINET IO defines how all data is exchanged between controllers (masters) and devices
(slaves) and how parameter settings and diagnostics are handled. The bus system is designed to exchange data
between Ethernet-based field devices using the producer/consumer model.
X20 modules or other modules that are 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.
