Foxtrot – system overview

Small in size. Big in architecture.

Foxtrot is a compact modular PLC with a professional I/O system, deterministic communication, and full integration into the IP world.

Foxtrot – system overview

Foxtrot combines simple DIN-rail mounting with a professional control architecture and exceptional expandability.
It was designed as a compact alternative to modular PLC systems—without compromises in I/O, communication, or long-term stability.

One platform, multiple variants

Foxtrot is defined by a compact base module that simultaneously serves as:

  • the system controller,

  • a communication node,

  • the master of expansion buses.

Depending on the application, the following variants are available:

  • base modules with integrated I/O,

  • base modules without I/O,

  • customer-specific embedded variants (OEM, Open Frame).

➡️ All built on a single shared platform.

Modularity through two buses

Foxtrot base modules can be expanded simultaneously using two types of buses.

CIB® – installation bus

  • deterministic Master/Slave communication,

  • two-wire system (data + power),

  • free topology without termination resistors,

  • reach of up to 500 m on the longest branch,

  • designed for sensors, actuators, and elements in distributed installations.

TCL2 – PLC system bus

  • high-speed serial connection,

  • deterministic communication,

  • designed for fast PLC I/O in accordance with IEC 61131.

➡️ Both buses can operate simultaneously in real time within a single system.

Ethernet as a natural part of the system

The new generation of CP-2xxx base modules:

  • always includes two Ethernet interfaces,

  • enables secure remote management via TecoRoute,

  • supports operation in two separate LAN networks.

WiFi – flexible wireless access

The WiFi interface via the USB port enables:

  • convenient wireless service access,

  • local visualization on mobile devices,

  • temporary or mobile installations.

WiFi is not an add-on—it is a fully-fledged third network interface of Foxtrot.

Integrated LTE modem

Selected base modules with I/O can be equipped with an integrated LTE modem:

  • Foxtrot remains online even where no network infrastructure is available,

  • direct connection to the mobile network

    • without an additional router,

    • without external power supply,

    • without configuration of third-party devices.

Typical use cases:

  • measurement and control without customer IT infrastructure,

  • energy technologies in the field,

  • temporary installations,

  • backup communication channel,

  • secure remote management via TecoRoute.

LTE is not an add-on—it is a fully-fledged fourth network interface of Foxtrot.

Why Foxtrot

Foxtrot is not based on experimental or educational platforms, but on:

  • a proprietary, well-designed I/O system,

  • deterministic communication,

  • long-term backward compatibility of software and communication,

  • centralized firmware management.

Foxtrot is a system designed for installations that must operate reliably for years—anywhere in the world.
