Communication & interfaces

Foxtrot – the communication hub of your automation project

Modern automation projects are no longer just about controlling inputs and outputs.
They are about communication—between technologies, systems, people, and remote services.

Foxtrot is designed as the central communication hub of the project, connecting these worlds within a single device—without external gateways, routers, or computers.

One system, multiple communication paths at the same time

Foxtrot allows parallel use of:

  • wired IP communication (Ethernet)

  • wireless communication (WiFi)

  • mobile connectivity (LTE)

  • serial lines and industrial buses

All channels can operate simultaneously and in real time, without compromising technology control.

Separation of networks, roles, and responsibilities

Thanks to multiple independent communication interfaces, Foxtrot can:

  • separate the technology network from IT infrastructure,

  • allow service access without interfering with operation,

  • act as a bridge between different communication domains.

The system designer is not limited to a single “correct” connection method—
Foxtrot adapts to the project architecture, not the other way around.

Online even where no network exists

Selected Foxtrot base modules feature an integrated LTE modem.
This enables remote monitoring, management, and service even in locations without fixed infrastructure:

  • energy systems and renewables

  • field technologies

  • temporary or mobile installations

  • backup communication paths

No external routers. No additional devices.

Recommendation:
Before going to the catalog, review the individual application areas first.
This will help you better understand which Foxtrot communication options make sense for your project.
