The KNX Modbus TCP Gateway 716 is a compact gateway between KNX TP and Modbus TCP with 250 freely configurable data points.
The device allows for easy integration of Modbus devices that support the TCP over IP protocol and can act as a Modbus master or slave. As a master, the device can address up to 5 slave devices. Two buttons and three LEDs allow for local operation and display of the device status.
In addition, the device can be used as a programming interface to connect one or more PCs to the KNX bus (e.g., for ETS®). Power is supplied via the KNX bus. The KNX Modbus TCP gateway supports KNX security.

The assignment between KNX objects and Modbus registers is done via ETS parameters, without the need for other tools.

The device allows Modbus data to be interpreted and scaled according to KNX standard data point types.
Two buttons and three multicolored LEDs on the front panel allow for local operation (test functions) and display of the device status.
