LOGO! CSM: local Ethernet switching for networked setup
The LOGO! CSM extends local Ethernet connectivity for LOGO! 9 applications — enabling multiple devices to share one network segment without additional switching hardware.
Why LOGO! Communication Modules?
LOGO! Communication Modules extend LOGO! 9 applications with dedicated connectivity — for local network integration, KNX building automation, and flexible data exchange with connected systems. All communication modules from previous LOGO! generations remain fully compatible with LOGO! 9.
From Ethernet switching to KNX integration and software communication: the LOGO! Communication Module portfolio covers the connectivity needs of Everyday Automation without additional engineering complexity.
Extend connectivity without changing your setup
LOGO! Communication Modules integrate directly into existing LOGO! 9 applications — no program changes required. All modules from previous LOGO! generations remain fully compatible with LOGO! 9 Basic Modules.
The right interface for every network environment
Whether Ethernet switching, KNX building networks, or software-based data exchange — LOGO! CSM, CMK 2000, and CIM cover the key connectivity scenarios for small automation applications in industry and buildings.
Connected applications without system complexity
LOGO! Communication Modules enable data exchange, remote integration, and network connectivity in a cost-efficient way — without oversized hardware or additional engineering overhead.
