IntesisBox is a Modbus RTU Master device allowing to read/write points of other Modbus RTU Slave device(s) connected to a Modbus RTU network, and offering these point's values through its KNX/EIB interface.

From the Modbus system point of view, after the start-up process, IntesisBox reads continuously the points configured to be read in the Modbus slave devices, and updates in its memory all the values received from the Modbus system. Points of Modbus devices can be read/written from KNX.

On the KNX side, IntesisBox simulates a KNX device and acts as if it was one more device into the KNX system.

The IntesisBox's KNX EIB interface connects directly to the EIB bus and is optoisolated from the rest of the internal electronics. Any point in IntesisBox can be configured individually for different functionality.
To allow read requests, to allow write requests, to automatically send a write request to the KNX bus when its value changes, and to send a read request to the KNX bus when IntesisBox starts-up or after a bus reset.

For each point, one main group address and different listening group addresses can be defined. This useful feature allows actions on the same internal point from multiple KNX group addresses.
