Certified Distributor


The SIMATIC IOT2040 is the reliable, open platform designed for the acquisition, processing and transfer of data directly in the production environment. It is ideally suited for use as a gateway between the cloud or company IT level and production. The openness of the system in supporting numerous communication protocols and programming in high-level languages enables tailored solutions.

Openness for industrial IOT applications:

  • Wide range of options for programming in high-level languages
  • Implementation of flexible communication solutions with different protocols, from Modbus RTU, OPC UA to cloud protocols such as MQTT/AMQP
  • Use of open source application examples and libraries
  • Yocto Linux support

The combined utilisation of machine and production data opens up a wide range of possible applications – the SIMATIC IOT2040 as a freely-programmable data gateway can establish the interface between the field and the IT/cloud. It can harmonise communication between the various sources of data before analysing it and forwarding it to the appropriate recipients. The SIMATIC IOT2040 can constitute an easy to retrofit, cost-efficient solution. This easy-to-implement solution facilitates the realisation of future-oriented production concepts on already existing systems.
