An industrial gateway is a rugged embedded computer that translates industrial protocols into cloud-friendly formats. It sits between your factory floor devices and IT systems, performing protocol conversion, edge computing, data filtering, and secure tunneling. The most common transformation is Modbus to MQTT. Modbus is the universal language of industrial devices but does not push data and has no built-in security. MQTT is the standard IoT protocol: lightweight, publish/subscribe, with TLS encryption. The gateway polls Modbus registers, converts values to JSON, and publishes to MQTT topics.
How can an industrial gateway bring legacy PLCs to the cloud? Tespro’s gateway has built-in parsing for over 200 protocols including Modbus, PROFINET, OPC UA, and IEC 104. It connects RS485 serial devices to Azure or AWS, enabling predictive maintenance and remote monitoring without replacing PLCs.
What if the cloud connection goes down? No data loss. Tespro gateways have onboard storage and store-and-forward, caching messages and replaying when connectivity returns. Redundant cloud brokers are also supported.
Tespro industrial gateway is the essential bridge between operational technology and information technology. Whether you need to bring Modbus devices to the cloud, aggregate building data, or enable remote PLC access, a Tespro gateway delivers reliability and flexibility.Contact www.tespro.com for sample units and technical specifications.
