With LOGO! 9, Siemens marks a complete generational shift after 11 years and sets new standards in "Everyday Automation": significantly improved performance combined with modern operation, flexible engineering, and advanced safety, tailored to the requirements of today's automation projects. LOGO! 9 will be available from April 1, 2026.
LOGO! 9 offers twice the number of function blocks, up to 800, enabling significantly more complex logic applications without the need for additional control devices in many cases. Extended expansion, with up to 64 digital inputs, 60 digital outputs, and 16 analog inputs and outputs each, provides ample space for larger and more demanding projects. The new Analog Expansion Module (AM4), with selectable analog resolution, along with new calculation functions and floating-point support, allows for precise control and processing of measured values directly on the controller. These performance enhancements offer greater flexibility, fewer additional components, and less effort throughout the entire lifecycle, without unnecessarily complicating the architecture.
The new color touchscreen (320 × 240 px resolution) on the base module displays more information at a glance, ensuring clear operation and quick diagnostics. For even better visualization and maximum readability directly on the machine, the new 4.3-inch LOGO! text display (480 × 272 px) with two Ethernet ports and secure communication with the base module is also available.
LOGO! Soft Comfort Version 9 software is available as a plug-and-play solution via USB and is fully compatible with previous projects and generations. The integrated LOGO! Web Editor, included with simulation, is a cross-platform tool and now supports macOS and Linux, in addition to Windows. The new user management system (UMAC) with four roles ensures clear permission distribution—from administrator to operator—and significantly accelerates engineering processes.
LOGO! 9 complies with Siemens' EcoTech label, adapting to future sustainability requirements. Secure Boot and secure LOGO! communication protect against tampering and unauthorized access. Firmware updates via LSC (LOGO! Soft Comfort) and factory reset with IP retention ensure safe and efficient operation throughout its lifecycle. The combination of security and sustainability makes LOGO! 9 a future-proof solution.
"The requirements for compact controllers have fundamentally changed. What could previously be achieved with simple logic functions now requires precise data processing, intuitive operating concepts, and comprehensive safety. LOGO! 9 combines, for the first time, the computing power and safety standards of larger systems with the simplicity and cost-effectiveness of a compact logic module, ensuring that our customers' applications are future-proof," says Annemarie Große Frie, Head of Automation Systems at Siemens Digital Industries.
