Description

The MDIM-485/WL is a compact, industrial serial server designed to bridge the gap between legacy RS485 fieldbus networks and modern IP infrastructure. It functions as a transparent gateway, enabling seamless, bidirectional communication between Modbus RTU devices on a serial line and Modbus TCP/IP clients over Ethernet or Wi-Fi. This eliminates the need for hardware changes when integrating industrial automation equipment into centralized SCADA, HMI, or IoT platforms.

Engineered for demanding environments, the gateway accepts a wide-range DC power supply from 6V to 36V, with typical operation at 12V or 24V DC. Its robust electrical design incorporates protection against voltage surges, ESD, and fluctuations, ensuring stable operation in facilities like factories, utility substations, and building management systems. The device supports configurable baud rates from 50 to 921,600 bps and includes a dedicated software utility for straightforward configuration of network parameters, protocol settings, and operational mode switching between Ethernet and Wi-Fi.

Key Features

  • Transparent RS485 to IP Bridge: Enables direct, unmodified data pass-through between serial Modbus RTU networks and Ethernet/Wi-Fi Modbus TCP networks.
  • Selectable Wired/Wireless Operation: Configure for reliable 10/100 Mbps Ethernet or flexible 2.4 GHz Wi-Fi (150 Mbps) connectivity based on installation requirements.
  • Industrial Power & Protection: Wide 6-36V DC input range with built-in surge and ESD safeguards for resilience against industrial power noise and transients.
  • High-Speed, Low-Latency Communication: Supports baud rates up to 921,600 bps for fast data exchange critical in real-time monitoring and control applications.
  • Multi-Device Gateway: A single unit can connect and manage communication for multiple RS485 slave devices, reducing hardware complexity and cost.
  • Extended Temperature Operation: Rated for continuous use from -40°C to +85°C, suitable for outdoor enclosures or unregulated indoor environments.
  • Compact, Mountable Enclosure: Designed for DIN-rail or panel mounting with dimensions of 100mm x 80mm, facilitating easy integration into control cabinets.
  • Dedicated Configuration Software: Includes an application for easy setup of IP addresses, Wi-Fi credentials, serial parameters, and Modbus mapping.

Applications

  • Factory Automation & SCADA Systems: Bridging PLCs, sensors, and motor drives on RS485 networks to central monitoring platforms over Ethernet or plant Wi-Fi.
  • Building Management Systems (BMS): Integrating HVAC controllers, lighting panels, and access control systems with IP-based BMS software.
  • Energy & Utility Monitoring: Connecting Modbus RTU power meters, solar inverters, and grid sensors to data acquisition servers for real-time analytics.
  • Industrial Process Control: Linking field instruments, flow meters, and control panels in water treatment or manufacturing to supervisory HMI systems.
  • Remote Telemetry & IIoT: Enabling wireless (Wi-Fi) connectivity for RS485-based environmental sensors or tank level gauges in distributed sites.

Frequently Asked Questions

How do I configure the MDIM-485/WL gateway for my network?

Use the dedicated Configuration Application provided by the manufacturer. Connect the gateway to your PC via Ethernet, launch the software to discover the device, and set the desired operating mode (Ethernet or Wi-Fi), IP address, subnet mask, gateway, Wi-Fi SSID/password (if used), and serial parameters like baud rate and parity. The software allows you to save configurations and monitor the gateway's communication status.

What is the power supply requirement for this RS485 gateway?

The MDIM-485/WL accepts a wide-range DC input from 6V to 36V, with 12V or 24V DC being typical for industrial applications. It draws approximately 600mA operating current. Ensure your power source can provide stable voltage within this range and is capable of delivering at least 3W of power. The gateway includes built-in protection against surges and voltage fluctuations for enhanced reliability.

Can this device connect multiple RS485 slave devices?

Yes, the MDIM-485/WL acts as a multi-slave gateway. You can connect several Modbus RTU slave devices (like sensors, meters, or PLCs) on a single RS485 bus. The gateway transparently bridges all serial communication to the IP network, allowing your Modbus TCP master software (e.g., SCADA, HMI) to individually address each slave device using its unique Modbus unit ID without requiring hardware changes.

How do I switch between Ethernet and Wi-Fi operation?

Switching is done via the Configuration Application. During setup, you select the primary network interface—either Ethernet or Wi-Fi. You can configure fallback settings, but only one interface is active for data transmission at a time. The device does not simultaneously bridge data over both connections. Reconfiguration is required to change the active network mode after initial setup.
