How Do Industrial Cellular Routers Work?

4G industrial cellular routers enable fast, reliable connection between multiple devices and peripherals, from PLCs to sensors. They leverage IP-based 4G networks to send and receive data, creating secure machine connectivity at any location or installation.

All data received by the 4G industrial router is transferred to a cloud-based service (like AWS) through MQTT communication, where it can be analyzed and distributed via SMS or email. This technology provides a comprehensive system for gathering, interpreting, and disseminating machine data to improve overall performance while reducing costly maintenance trips to the installation site.

4G industrial cellular routers offer better response time and lower latency than legacy solutions, driving faster connectivity for machines in the field. Designed for data security and robust dependability, 4G routers are a natural choice for remote installations and harsh environments. KEB models are made with rugged, industrial materials with no moving parts or fans, along with cULus approvals and an IP20 protection grade.

Advantages of 4G Industrial Routers

High-quality 4G industrial routers are designed for flexibility. For example, KEB’s C6 router offers additional HMI functionality for data logging, long-term machine diagnostics, and notification via email and SMS. This versatility makes the C6 useful for remote monitoring of devices through Ethernet or serial interface. The C6 can also be used on any GSM network in any country.

Compatibility with VPN connection software (like COMBIVIS Connect) is another unique advantage of 4G industrial routers. This technology empowers users to monitor a plant or installation from their workplace through a highly secure VPN. Moreover, KEB 4G routers offer worldwide support through multiple server locations to ensure continuous network connection.

Applications for 4G Industrial Routers

A 4G industrial router is a definitive tool for remote PLC maintenance and commissioning, particularly in hard-to-reach locations and installations. This utility makes them suitable for real-time facility monitoring and internal communication across wastewater treatment systems.

Renewable energy and wind power applications can monitor and maintain isolated assets in the field, such as wind turbines, with the help of a 4G industrial router. Other typical applications include oil fields, SCADA, and Discrete Automation.

KEB’s C6 industrial cellular router helps machine builders and IoT system integrators maximize site efficiency and safety through remote PLC maintenance. Our solution makes it easy for users to perform analytics, gauge KPIs, and streamline their decision-making processes. Our team can help you select the optimal router for your unique application needs.
