Siemens PROFINET Ethernet Protocol and Network Configuration

PROFINET is an Ethernet protocol for industrial networking that uses Siemens hardware. PROFINET is one of the choice Ethernet standards in PLC automation: it maintains a universal, wireless communication protocol for all applications. As a method of device-to-device communication, PROFINET acts as the controller of the system in order to talk to the other devices that are part of the system, such as remote IO racks, VFDs and other third-party devices. From standard PLC to PLC communication to motion control applications, the PROFINET industrial Ethernet network ensures optimal performance and equipment independence for all of your machines.

PROFIBUS and PROFINET Integration

PROFIBUS is Siemens’ original fieldbus: PROFINET combines PROFIBUS and Ethernet ensuring more flexible and efficient machine processes.
