The Future-Ready Distributed I/O System

When it comes to distributed automation, the I/O system needs to fit the application, not the other way around. Some applications need compact systems inside the control cabinet. Others need rugged I/O installed directly on the machine, with options for harsh industrial environments and hazardous areas. Siemens SIMATIC ET 200 is designed for this flexibility, giving users a distributed I/O portfolio that can be scaled, installed and configured around the requirements of the application.

The portfolio supports distributed automation across a wide range of applications, with flexible IP20 systems for cabinet-based installations and rugged IP65/67 systems for use directly at the machine. This gives users a choice of compact
in-cabinet modules through to rugged designs for outside the cabinet, depending on the environment and application.

At the heart of SIMATIC ET 200 is a modular design that can be scaled and expanded in small steps. This allows users to build the right configuration for the job, from digital and analogue I/O through to intelligent modules with CPU functionality, safety engineering, motor starters, frequency converters and technology modules. For specialised applications, SIMATIC ET 200 also supports functions such as weighing, energy management and IO-Link connection.

The benefits go beyond installation flexibility. SIMATIC ET 200 supports fast commissioning, simple cabling and integrated system diagnostics, helping users save time during setup, simplify wiring and troubleshoot faster when issues occur. TIA Portal also supports the integration of standard and safety functions in one automation solution, using shared controllers, shared engineering and shared communication structures.

From compact cabinet layouts to rugged machine-mounted installations, SIMATIC ET 200 gives users a flexible, scalable and space-saving way to connect sensors, actuators and automation systems across modern industrial applications.

SIMATIC ET 200MP

SIMATIC ET 200MP is the cabinet-based option for applications that need high performance, high channel density and a close fit with the SIMATIC S7-1500 automation platform. Designed for IP20 installation, it can be used as central I/O for the S7-1500 or as a distributed system, giving users flexibility in how the control architecture is built. Its modular and scalable design supports compact cabinet layouts, while low parts variance helps keep the system streamlined. For teams working on small series machines or complex plants with high demands on speed and deterministic response, ET 200MP provides a powerful foundation inside the control cabinet.

The system is also built around easier setup and faster fault finding. Push-in terminals, tool-free cabling and shielding terminals support quick station setup, while integrated diagnostics with clear module displays and 1:1 LED-to-channel assignment help localise errors quickly. With fail-safe modules, technology modules and options for digital and analogue I/O, CPUs and motor starters, ET 200MP brings broad functionality into a scalable cabinet-based I/O system.
