Gateway Modbus RS485 - KNX
GATEWAYS
Description
The Ekinex® Modbus RS485 - KNX Gateway performs a protocol conversion between
a serial RS485 Modbus RTU 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.
Main features
• Plastic casing
• Connection to bus line with KNX terminal block
• Installation on 35 mm rail (according to EN 60715)
• 4 modular units (1 MU = 18 mm)
• IP20 protection degree (installed device)
• Weight 145 g
Technical data
• Power supply: 8...24 Vac or 12...35 Vdc
• Absorption at 24 Vdc: 3,5 VA
Communication
KNX side
• KNX TP (Twisted Pair) communication port electrically isolated from power supply
• 1440-byte volatile support “KNX image” memory buffer
Modbus RS485 side
• RS485 serial communication port, electrically isolated from power supply,
120 ohm termination resistance pluggable by a 1-way micro-switch
• Modbus master RTU (Remote Terminal Unit) communication
• Selectable baud rate from 1200 to 115200 baud
• Device addressing from 0 to 250
• Coil, Input, Holding Register e Input Register data exchange
• Single and multiple register reading/writing
• 1440-byte volatile support “Modbus image” memory buffer
Configuration
• Ethernet communication port (IEEE 802.3), RJ45 connector, minimum cable
category: 5E
Delivery
The delivery includes the device and terminal blocks to connect to the KNX bus.
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.
