SIMATIC ET 200 - The distributed I/O system for future-proof plants
Integrated and optimized data availability along the entire value-added chain is the basis for innovative business models. This also places special demands on your distributed I/O: flexible scalability of the systems, high-performance hardware in the field, smart features. With SIMATIC ET 200, you get more out of your data and tap the full potential of your I/O system.
Automation with SIMATIC ET 200 - flexible, powerful, smart
No matter whether you are looking for space-saving solutions for the control cabinet or robust modules with IP65/IP67 degree of protection. With SIMATIC ET 200, you can fulfill almost any requirement cost-effectively. Permanent data availability from engineering to plant operation makes the ET 200 an integrated data hub. What’s more, you invest in the future-proofing of your machines and become ready for new business models such as "production as a service"
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.ET 200 system features – integrated added value
With the SIMATIC ET 200 modular I/O system, you automatically benefit from numerous integrated functions and features. This allows you to implement even complex machine and plant concepts in no time at all.SIMATIC ET 200 in use

Security information
In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’ products and solutions only form one element of such a concept. For more information about industrial security, please visit.
