Why LOGO! Basic Modules?

LOGO! 9 Basic Modules put more power where you need it: up to 800 function blocks, floating-point arithmetic, and an integrated colour touch display — without the complexity of a full PLC platform.

Built to scale, the modular system supports up to 64 DI / 60 DQ / 16 AI / 16 AQ and comes with Security-by-Design as standard. One compact device. Ready for what's next.

Built for Everyday Automation

LOGO! 9 combines the familiar simplicity of a logic module with new capabilities: up to 800 function blocks, floating-point arithmetic, and an integrated colour touch display — all in one compact device.

More scope for growing applications

As your application grows, LOGO! 9 scales with it — up to 64 DI, 60 DQ, 16 AI, and 16 AQ. The new AM4 module adds flexible analogue I/O expansion with selectable resolution for diverse sensor types.

Faster from idea to running application

LOGO! Soft Comfort V9 integrates programming, web visualisation, and simulation in one tool — fully compatible with older projects and available on Windows, macOS, and Linux.

Frequently asked questions

Programs are fully compatible and can be converted bidirectionally using LOGO! Soft Comfort V9. Note that older digital and analogue expansion modules are not hardware-compatible with LOGO! 9 — however, existing communication modules remain compatible.

LOGO! 9 Basic Modules are available in multiple supply voltage variants (12/24 V DC, 24 V AC/DC, 230 V AC/DC) and with or without an integrated display. If local operation and visualisation are required, choose a module with a display. Use the TIA Selection Tool to find the right variant based on your specific I/O and voltage requirements.

LOGO! 9 Basic Modules, the LOGO! TDE, three expansion modules, and LOGO! Soft Comfort V9 will be available for pre-order in April 2026 — the exact date will be communicated shortly. First deliveries are expected from late April / early May 2026. Eight additional expansion modules, including further DM16 and AM variants, are planned for Q1 2027.

LOGO! 9 brings four major Added Values over LOGO! 8:

More Power & Application Space: LOGO! 9 doubles the number of function blocks to 800, adds floating-point arithmetic for more precise analogue processing, and introduces the new AM4 module with selectable analogue resolution — giving you significantly more headroom for demanding applications without additional hardware.

Modern Operating & Display Experience: The new built-in colour touch display and the updated 4.3" LOGO! TDE deliver status information, message texts, and diagnostics directly at the device — for faster response in the field and a professional appearance without additional HMI hardware.

Efficient & Flexible Engineering: LOGO! Soft Comfort V9 integrates the LOGO! Web Editor, including simulation in a single tool, is now also available for macOS and Linux. Combined with the new four-role user management (UMAC), engineering becomes faster, more flexible, and more governed across teams.

Security & Sustainability by Design: Secure Boot and encrypted device-to-device communication protect against unauthorised access and manipulation. Firmware updates via LSC with IP retention ensure service-friendly operation.
