The Siemens SIMATIC ET 200SP Open Controller is a groundbreaking device that redefines industrial control by merging the flexibility of a PC with the robustness and real-time capability of a PLC. As the first controller to combine a PC-based SIMATIC S7-1500 software controller with PC applications and central I/Os in a single compact device, it offers unparalleled versatility for modern automation challenges.

Convergence of PC and PLC

This controller uniquely integrates a powerful PC platform with a high-performance software PLC. This allows it to execute complex control logic (via the S7-1500 software controller) independently of the operating system, while simultaneously running PC-based applications for tasks such as data processing, communication, and visualization. This fusion simplifies system architectures, reduces hardware costs, and enhances overall performance.

Performance and Flexibility

At its core, the ET 200SP Open Controller is powered by an Intel Atom E3940 Quad-Core processor (1.6 GHz), paired with up to 8 GB of DDR3L RAM. For storage, it utilizes robust CFast cards with capacities up to 128 GB. It supports both Windows 10 IoT Enterprise LTSC 2019 and a Linux-based SIMATIC Industrial OS, giving engineers the freedom to choose the optimal platform for their application. The controller delivers exceptional real-time performance, with the ability to process digital input and output signals in as little as 1 µs and analog signals as of 50 µs.

Integrated Safety and Scalability

The ET 200SP Open Controller is available in standard, technology (T), failsafe (F), and failsafe technology (TF) versions. The failsafe variants integrate safety functionality directly into the controller, enabling both standard and safety-related tasks (up to SIL 3 / PL e) to be handled by a single device. This reduces engineering overhead and cabinet space. The controller's functionality can be seamlessly expanded using the extensive SIMATIC ET 200SP I/O portfolio, including digital, analog, and technology modules. Integrated PROFINET interfaces (including an IRT-capable port) ensure high-speed, deterministic communication.

Simplified Engineering with TIA Portal

All configuration, programming, and diagnostics are performed within the Siemens TIA Portal engineering framework. The software controller is programmed using standard S7-1500 languages (LAD, FBD, SCL, STL, S7-Graph), while PC applications can be developed in high-level languages like C and C++. Pre-installed WinCC Runtime Advanced options provide powerful visualization capabilities right out of the box.

Applications

The SIMATIC ET 200SP Open Controller is ideally suited for applications that demand a high degree of integration and openness, including:

• Special-purpose and series machine building
• Machines with distributed intelligence
• Applications requiring integration of high-level languages (C/C++) with PLC logic
• Systems combining control, data processing, and communication tasks
