PROTOCOL CONVERTER (RS485 MODBUS TO ETHERNET) ET-485

ET-485 is a microcontroller unit. It is designed to exchange data over the Ethernet 10BASE-T and 100BASE-T network using the equipment, which is provided with the RS-485 interface and establishing a Modbus network. The standard network mapping using the RS-485 is provided. The unit fulfills the functions of a ‘Modbus Server’ for switching the Modbus clients to the Ethernet network. It redirects the Modbus requests from the clients to the units in the Modbus network and returns their answers to the clients.

ET-485 has:

• Flexible addressing within the Ethernet network (overloading MAC-address, static and dynamic IP- address)
• Access protection over the Ethernet network (password for configuration mode, IP- address filter for setting and switching to the Modbus network)
• Different data transfer modes for Modbus network (RTU and ASCII with/without odd-even check, wide range of transmission speeds, selectable delays)
• Free PC software for programming/settings and monitoring
