  • Page 6: Safety

    Safety 4 (32) Safety Connecting power with reverse polarity or using the wrong type of power supply may damage the equipment. Make sure that the power supply is connected correctly and of the recommended type. This product contains parts that can be damaged by electrostatic discharge (ESD). Use ESD prevention measures to avoid damage.

  • Page 7: Product Description

    Product Description General The Anybus Modbus to KNX Gateway is intended for integration of Modbus RTU and Modbus TCP installations into KNX monitoring and control systems. On the KNX side the gateway acts as a KNX device, and on the Modbus side it emulates a Modbus RTU Master device and/or a Modbus TCP Client device.

  • Page 8: Knx Interface

    Product Description 6 (32) KNX Interface The gateway connects directly to the KNX TP-1 (EIB) bus and behaves as one more device in the KNX system, with the same configuration and operational characteristics as other KNX devices. Internally, the circuit part connected to the KNX bus is opto-isolated from the rest of the electronics.

  • Page 9: Modbus Interface

    Product Description 7 (32) Modbus Interface Modbus TCP basically embeds the Modbus RTU protocol in TCP/IP frames. TCP/IP allows faster communication and a longer distance between the master and slave devices than RTU communication over serial line. Modbus TCP allows communication over an existing TCP/IP infrastructure such as a LAN, WAN or the Internet.
