TRANSLATOR – MODBUS TCP-IP to MODBUS RTU Converter

Short description: A rugged microcontroller-based Ethernet-to-Serial protocol converter that translates MODBUS TCP-IP protocol (Ethernet master) to MODBUS RTU protocol (RS232/RS485 slave). Ideal for SCADA and industrial automation systems requiring TCP to RTU bridging.

Key Features

• Ruggedised, microcontroller-based DIN-rail mount system.
• Converts MODBUS TCP-IP protocol (Ethernet master side) to MODBUS RTU protocol (RS232/RS485 slave side).
• Supports multiple RS485 MODBUS RTU slave units on the slave side.
• Reads/writes all MODBUS slave registers: coil status, input status, holding registers, and input registers.
• User-selectable MODBUS RTU baud rate via DIP switch: 9600, 19200, 38400, 57600 bps.
• Fixed MODBUS TCP-IP master baud rate: 115.2 kbps; station ID: 1.
• On request: Slave-side MODBUS TCP with master-side MODBUS RTU available.
• LED indications for power, system OK, Ethernet status, and master/slave Tx/Rx for easy diagnostics.
• DIN rail ABS enclosure for industrial environments.

Technical Specifications
