You can use the Ethernet protocols PROFINET, Modbus TCP, und EtherNet/IP with MultiFieldbus
SIMATIC MultiFieldbus

Use different Ethernet protocols with the MultiFieldbus

The MultiFieldbus enables the use of the Ethernet protocols PROFINET, Modbus TCP and EtherNet/IP independent of the controllers and I/Os used. The MultiFieldbus is therefore also the solution if an application is to be set up with different controllers (fieldbuses) and the I/O system is to continue to be used unchanged.

I/O systems with integrated data handling

In times of strong competition and new technologies, integrated data handling can become a decisive competitive advantage. Consistent data handling already starts in the planning stage. This saves time and money already during engineering. For this purpose, we provide you with an integrated tool landscape.
