LOGO! Logic Module

LOGO! 9 is a compact logic module for Everyday Automation — ideal for standalone applications in machine and building automation. It combines a built-in color touch display, Ethernet connectivity, and security by design in a cost-effective package.

LOGO! 9 doubles the function blocks to 800, adds a built-in color touch display, supports floating-point arithmetic, and introduces role-based user management (UMAC with 4 roles) and security by default — while keeping the simplicity and cost efficiency LOGO! is known for.

Yes. Programs are bidirectionally compatible across all LOGO! generations via LOGO! Soft Comfort V9. Note that older expansion modules are not hardware-compatible with LOGO! 9, but all existing communication modules are fully compatible — no hardware replacement needed.

LOGO! 9 supports Modbus TCP/IP and MQTT out of the box, plus an integrated web server for browser-based monitoring and visualization — no custom solutions or additional hardware required.

Your existing programs transfer directly via LOGO! Soft Comfort V9. Communication modules can be reused without replacement. Only expansion modules need to be exchanged — the new DM8 and AM4 modules are available from April 2026, with further expansion modules following in Q1 2027.

LOGO! 9 is designed for standalone Everyday Automation: switching, timing, counting, and monitoring in machine building, panel construction, and building automation — fast to engineer, compact, and cost-efficient. For applications that require motion control, fail-safe functions, PROFINET IO, or TIA Portal-based engineering, the SIMATIC S7-1200 G2 and S7-1500 are the right next step in the Siemens portfolio. Both share the same commitment to simplicity, security, and scalability — just at a different level of complexity.
