IIoT gateways
IIoT gateways act as a secure intermediary between OT equipment and IT platforms, enabling seamless data transfer and management. They support industrial protocols such as Modbus RTU/TCP, OPC UA and MQTT, as well as cloud-facing MQTT solutions such as Azure IoT Edge and AWS IoT Core. Azure IoT Edge and AWS IoT Core.
Gateways are equipped with encryption, firewall, authentication and secure boot, protecting communication between field devices and IT systems.
Areas of application
Combines Modbus data with MQTT, Azure IoT or AWS interfaces and serves as easy-to-use solutions with minimal programming for cloud integration.
Programmable gateways (Arm or x86-based) handle local data analysis, protocol translation and secure buffer/forward via MQTT/Modbus/OPC UA.
Use in environments without a fixed network: gateways with LTE ensure connectivity via mobile networks and Dual SIM ensures failover and continuous operation.
With TPM, Secure Boot and HTTPS/SSH, secure firmware update (OTA), access control and remote management via web or API are supported.
Why choose IIoT gateway?
Protocol bridges instead of full replacements
Devices translate between OT protocols and IT systems to preserve and integrate existing equipment
Local intelligence and buffer
Prevents data loss during temporary network outages
Cloud support without development
Pre-installed SDKs and integration to Azure/AWS save time on setup
Robust for use in extreme environments
Operating temperatures from -40°C to +70°C and industrial options like fanless, rugged design and DIN rail mounting
