Description

With integrated Wi-Fi and Ethernet interfaces, the ModProBus ISM842 RF Gateway enables RF-based field systems to be securely integrated with SCADA systems and IoT platforms. Data collected via Modbus RTU and Modbus TCP can be converted to MQTT using the built-in protocol support, making it suitable for modern IoT architectures. The integrated firewall provides a controlled and secure boundary between the RF field network and IP-based systems.

Thanks to its built-in automatic data collection and rule engine, logical operations, I/O data transfers, and condition-based actions can be executed locally in the field without the need for a centralized controller. With support for Modbus RTU and Modbus TCP/IP and an integrated I/O structure, the ModProBus ISM842 RF Gateway offers a powerful and flexible solution for remote I/O, wireless automation, and industrial IoT integration applications.

Fast and Easy Installation

Designed for quick commissioning, the ModProBus ISM842 RF Gateway enables fast and effortless installation in the field. In case of temporary network interruptions, the device automatically reconnects, ensuring continuous and reliable system operation.

Easy Mounting and Setup

With DIN rail mounting support, the ModProBus ISM842 RF Gateway can be installed quickly and securely in control panels. Thanks to its web-based user interface and built-in Wi-Fi Access Point capability, the device can be easily configured without the need for additional equipment.

Automatic Data Collection

The ModProBus ISM842 RF Gateway automatically reads data from connected devices and ensures that up-to-date information is delivered to the system. Periodic data polling and configurable condition-based actions help reduce unnecessary data transmission and improve overall system efficiency.
