Get a real head start on the topic of Industry 4.0 with C-Gate. You can retrofit C-Gate for existing systems and welding machines as well as include it in your next new order. This page gives you an overview of how C-Gate is integrated and what you need to use C-Gate.

C-Gate IoT Platform

C-Gate IoT Hub

  • Server application
  • C-Gate software modules

C-Gate IoT Connector

  • Edge Gateway
  • Data buffer
  • Network security


  • Robot systems
  • Welding equipment
  • PLCs
C-Gate IoT Hub

The C-Gate IoT Hub Previously referred to as C-Gate server. is a software application and forms the centre of the data flow. The functionality of the hub is extended by the respective software modules. One hub is recommended per site, which can be installed on a server or PC.

Tasks of the IoT Hub:

  • Central data management and configuration
  • Interface to MES and ERP systems
  • Data visualisation
Installation and first steps
C-Gate IoT Connector

The C-Gate IoT Connector is an edge gateway in the form of an industrial PC that is installed close to the system or in the welding device. It serves as a connector between the device and the IoT Hub.

Tasks of the IoT Connector:

  • Offline provision of IoT Hub data
  • Secured transmission and buffering of the unit data
  • Separation of machine network and other networks

Prerequisites of the controls

These requirements apply to existing devices. If you order new systems or devices with C-Gate, they will be equipped with the appropriate options ex works.
