Gateway Modbus TCP/IP master - KNX

Code: EK-BH1-TP-TCP

Description

The Ekinex® Modbus TCP/IP - KNX Gateway performs a protocol conversion between a Modbus RTU over TCP/IP and a KNX TP network. The device works as Modbus master.

The device integrates a KNX bus communication module and it is suitable for mounting on a 35 mm DIN rail; it requires an auxiliary power supply (8...24 Vac or 12...35 Vdc).

The device manages bidirectional data flow: Modbus registers can be periodically read and their values transmitted to configured group addresses over the KNX TP network. Group address value changes on the KNX bus are detected to write values into registers of one or more Modbus slave devices.

Other information

Modbus® is an open source, standard communication protocol suitable for master/slave data exchange between smart devices in various applications, such as industrial production, infrastructure, transportation and energy management.
