Industrial IOT Gateway

Intelligent gateways for Industrial IoT solutions

The networking of production, IT, and cloud solutions continues to expand. Now it’s easy to implement forward-looking production concepts in your existing plant with SIMATIC IOT gateways – they’re open, versatile, and retrofittable.


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

Highly flexible connection options:

  • Variety of interfaces on-board for simple connection
  • Simple and extremely flexible facilities with Arduino Shields and mPCIe cards

High degree of ruggedness for continuous operation in industrial environments:

  • Designed for continuous operation at ambient temperatures up to 50 °C and tough environmental conditions
  • Compact enclosure with diagnostics LEDs
  • Standard rail mounting for easy installation in the control cabinet

Deterministic response and performance for industrial applications:

  • Battery-backed real-time clock for assigning data to relevant timestamp
  • Intel Quark X1020 processor including x86 deterministic response and security feature such as Secure Boot


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.

Application examples:

  • Connection of additional sensors, and data collection and transfer in existing systems in order to identify optimisation potential
  • Acquisition of machine data, such as motor performance indicators, for analysis in order to derive preventive maintenance concepts
  • Coherence and harmonisation of communication from and between different machines and automation components
