Why LOGO! Communication Modules?

Compact automation rarely works in isolation. Communication modules extend a LOGO! 9 installation beyond the controller’s integrated Ethernet interface when extra network ports, KNX integration or serial communication are required. Existing supported modules can continue to be used, helping customers preserve established connectivity concepts during a generation change.

Build on the hardware you know

Keep supported communication modules when modernizing to LOGO! 9 and avoid replacing a working interface without a clear technical reason.

Connect the devices your task needs

Choose local Ethernet switching, KNX building integration or serial data exchange according to the application.

Stay flexible as your needs grow

Add communication functions alongside I/O expansion without reducing the capacity reserved for LOGO! 9 digital and analog extension modules.
