Advanced X-Monitor gateway with 4G/LTE-M modem and Wi-Fi™

The KET-RTU-310 Gateway, the central core of the X-Monitor network, stands out for its advanced functions and large memory capacity, key elements for efficient data management.

Connection flexibility is ensured by the integrated 4G/LTE-M modems (optional) and Wi-Fi™ support, eliminating the need for a LAN connection and expanding installation possibilities even in environments without cabling.

Thanks to the Linux operating system, the gateway utilizes standard libraries to ensure a high level of security and reliability in data transmission.

The installation and management of sensor networks, even complex ones, are extremely simple thanks to the included X-Manager software and the intuitive integrated web interfaces. These allow for quick configuration of the necessary parameters and real-time monitoring of acquired measurements.

In addition to the ability to export data to external platforms like X-Platform, the device offers a large internal SD memory capable of storing data for periods exceeding three months, ensuring operational continuity and the availability of measurement history.

The integrated RS485 port supports both Master RTU and Slave RTU modes, offering dual functionality: direct connection of devices to the gateway or access to the registers of connected devices via an external Master RTU.

The ModBUS TCP/IP server incorporated in the KET-RTU-310 facilitates the integration of the X-Monitornetwork with SCADA systems, PLCs (programmable logic controllers), and HMI (human-machine interface) systems, expanding data control and visualization possibilities.

Interoperability with proprietary data collection systems is further enhanced by support for data transmission via REST / JSON web services and the IEC 60870-5-104 protocol, ensuring flexible and standardized communication.
