Siemens LOGO! 9 Logic Module Features
800 Function Blocks
LOGO! 9 provides up to 800 function blocks, doubling the capacity available in the previous LOGO! 8 generation. This gives engineers additional space for larger and more detailed automation programs.
The increased program capacity makes LOGO! 9 suitable for applications where a basic relay logic controller may no longer provide sufficient functionality.
Integrated Colour Touch Display
Selected LOGO! 9 basic modules feature an integrated colour touch display, providing local access to status information, messages, diagnostics and operating functions.
This can reduce the need for a separate HMI in smaller automation systems where local visualisation is required.
Flexible I/O Expansion
The LOGO! 9 modular system can grow alongside your application. Depending on the configuration, the system can support up to:
- 64 digital inputs (DI)
- 60 digital outputs (DQ)
- 16 analogue inputs (AI)
- 16 analogue outputs (AQ)
The new AM4 analogue module provides additional analogue I/O flexibility with selectable resolution for different sensor and signal requirements.
Ethernet and Web Connectivity
Siemens LOGO! basic modules provide Ethernet connectivity for communication and engineering applications. The LOGO! platform also supports integrated web-server functionality and web visualisation.
This allows users to monitor and interact with automation applications through network-connected devices without necessarily installing a separate visualisation system.
LOGO! Soft Comfort V9
LOGO! Soft Comfort V9 provides a single environment for programming, simulation and web visualisation. The latest version also supports Windows, macOS and Linux, giving engineers greater flexibility when developing and testing LOGO! applications.
Existing LOGO! 8 programs can be converted bidirectionally using LOGO! Soft Comfort V9. However, Siemens notes that older digital and analogue expansion modules are not hardware-compatible with LOGO! 9, while existing communication modules remain compatible.
Security by Design
LOGO! 9 introduces enhanced security features designed to help protect automation systems from unauthorised access and manipulation.
Security-related features include Secure Boot and encrypted device-to-device communication. Firmware updates through LOGO! Soft Comfort can also retain IP settings, helping simplify maintenance and servicing.
Siemens LOGO! Basic Module Options
Siemens LOGO! 9 basic modules are available in different supply-voltage configurations and with or without an integrated display. Depending on the application, users can select the appropriate version according to voltage, I/O and visualisation requirements.

Siemens LOGO! vs Traditional PLC Systems
For smaller automation applications, a Siemens LOGO! logic module can provide a simpler alternative to implementing a larger PLC system.
LOGO! combines the controller, programming functionality and, on applicable models, local display capability in a compact unit. This can help reduce panel space, wiring and system complexity.
For larger and more complex automation projects, a conventional Siemens PLC platform may be more appropriate. LOGO! is particularly useful when the application requires compact control, straightforward programming, flexible I/O and economical automation.
