   * **Restartable** If enabled, the selected scene can be restarted if launched when already running; it is useful when the scenes is full of pauses and it is particularly long-lasting; when the scenery is launched from KNX, this property has to be disabled because of telegram repetitions.
   * **List of actions** By clicking on the button displayed on the right, the action editor will be displayed; the user can add the desired number of action by clicking on ”Add” button. Each action can be given a name and the related command can be selected by clicking on the button displayed on the right side of the dedicated slot.

   * **Datapoints** Data points collection
   * **Poll Interval** Pause between two consecutive polling sequences [ms]
+For each Datapoint created, the below parameters are available:
+  * **Name** datapoint label
+  * **Slave Address** Physical slave address of the device where the data is configured.
+  * **Data address** Data address where the data is stored.
+  * **Data type** type of data to read/write.
+  * **Read Function** Modbus standard function that has to be used to read the value (consult device manual).
+  * **Write Function** Modbus standard function that has to be used to write the value (consult device manual).
+  * **Bit number** number of bits inside the data that represent the value.
+  * **Conversion factor** conversion factor to multiply the read raw value.
+  * **Reuse** If several bits need to be read from the same address X, this parameter will help improve the reading speed by avoiding polling the slave every single time to read 1 different bit. For example, if multiple datapoints have been created for the same address, each datapoint with a different bit number to read from (typically each bit is a different toggle status), then only the first datapoint will have the "Reuse" parameter set to "False", while the other datapoints will have the "Reuse" parameter set to "True". The driver will read the 2 bytes from address X only the first time and will extract all the subsequent bits from this read value to populate the other datapoints.
+  * **Force rewrite** If enabled, permits to refresh (re-write) the last written value to the slave cyclically, based on the interval configured in "Write Refresh Interval" in the main settings.
+  * **Gateway KNX** if enabled, allows to read/write Modbus values from KNX system.
+  * **KNX data type** EIS data type that has to be written into the KNX group.
+  * **KNX group from Modbus** KNX group to read feedback from Modbus. Values are read from Modbus slaves and sent to this KNX group address.
+  * **Send if change** if enabled, sends value on KNX bus just in case Modbus value changes.
+  * **Enable KNX to Modbus** By default, the KNX gateway will read data from Modbus and send feedback to KNX. If bidirectional communication is needed, enable this parameter.
+  * **KNX group to Modbus** KNX group to receive value and write to Modbus. Values are received from this KNX group address and are written to Modbus.
