The Mikrodev DM100-E1N-GC0-B1000 is a highly flexible industrial RTU (Remote Terminal Unit) that excels in multi-protocol environments. Engineered for the demands of Industry 4.0, this compact device serves as both a powerful logic controller and a high-speed communication gateway, enabling seamless data flow between legacy serial infrastructure and modern Ethernet-based management systems.

Advanced Protocol Bridging

As a Modbus specialist, the DM100 allows for the simultaneous operation of Modbus TCP and Modbus RTU. It can act as a transparent gateway, allowing a Modbus TCP Master to communicate with multiple Modbus RTU Slaves over RS-485, or it can function as an active data aggregator, polling field devices and storing data in its internal registers for high-level SCADA systems to access via Ethernet. This versatility makes it an essential tool for retrofitting older industrial sites with modern monitoring capabilities.

Programmable Intelligence

Unlike standard protocol converters, the DM100 is fully programmable according to the international IEC 61131-3 standard. This means users can implement edge computing logic—such as local alarm thresholds, data pre-processing, or autonomous control loops—using familiar languages like Functional Block Diagram (FBD) or Structured Text (ST). This local intelligence ensures that critical processes continue to function even if the connection to the central server is temporarily lost.

Rugged Industrial Design

• High-Speed Processing: Driven by a 32-bit ARM core for low-latency communication and complex calculation handling.
• Industrial Connectivity: Independent RS-232 and RS-485 ports allow for connection to diverse devices like energy meters, sensors, and legacy PLCs.
• Compact Form Factor: Designed for DIN-rail mounting, fitting easily into space-constrained control panels.
• Wide Power Input: Supports a broad range of DC power (9-36V), ideal for varying industrial power standards.

Typical Applications

• Building Automation: Integrating serial HVAC and lighting sensors into a centralized Ethernet BMS.
• Energy Telemetry: Aggregating data from multiple RS-485 energy meters for transmission to a central cloud platform.
• Factory Floor Integration: Bridging legacy Modbus RTU equipment to a modern PROFINET or Ethernet/IP network architecture.
• Remote Sensing: Acting as a standalone controller for remote pump stations or environmental monitoring sites.
