Siemens presents LOGO! 9, the new generation of logic controller
LOGO! 9 with new color touchscreen display directly on the base module
"The requirements for compact controllers have fundamentally changed. What could once be realized with simple logic functions now requires precise data processing, intuitive operating concepts, and seamless security. LOGO! 9 combines the computing power and security standards of larger systems with the familiar simplicity and cost-effectiveness of a compact logic module for the first time, future-proofing our customers' applications," says Annemarie Große Frie, Head of Automation System at Siemens Digital Industries.
More performance and application scope for more demanding applications
LOGO! 9 offers twice the function block count with up to 800, enabling significantly more complex logic applications so that in many cases no additional control devices are required. The extended expansion level with up to 64 digital inputs, 60 digital outputs, and 16 analog inputs and outputs each creates scope for larger and more demanding projects. The new analog expansion module (AM4) with selectable analog resolution, along with new calculation functions and floating-point number support, enables precise control and measured value processing at the highest level directly in the controller. These performance enhancements mean greater application flexibility, fewer additional components, and therefore lower effort across the entire lifecycle – without unnecessarily complicating the architecture.
Modern operating and display experience directly on the device and efficient and flexible engineering for all platforms
The new touch color display (resolution 320 × 240 px) with the enlarged area directly on the base module displays more information at a glance, ensuring clear operation and fast 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 to the LOGO! base module is also available.
The software LOGO! Soft Comfort Version 9 is now available as a Plug & Play solution via USB stick and is fully compatible with older projects and generations. The integrated LOGO! Web Editor, including simulation, is a tool for all platforms and now supports macOS and Linux in addition to Windows. The new User Management (UMAC) with 4 roles ensures clear rights distribution – from administrator to operator – and significantly accelerates engineering processes.
Security and sustainability by design for the future
LOGO! 9 is prepared for the Siemens EcoTech label and thus for tomorrow's sustainability requirements. Secure Boot and secure LOGO! communication protect against unwanted manipulation and unauthorized access. Firmware updates via LSC (LOGO! Soft Comfort) and factory reset with IP retention guarantee secure and efficient operation throughout the entire lifecycle. The combination of security and sustainability makes LOGO! 9 a future-proof solution.
