2. consult the slave documentation for details of what function codes must be used for read and for write Use the following criteria for configuration of this kind of points in IntesisBox 1 If the Modbus function code to use for read is 03 and the function code to use for write is 06 which is very common then select the function code 3 Read analog registers in column Modbus Code and activate KNX flag W With this IntesisBox will use function code 03 for read the point in every polling cycle and whenever a write request for the point is received from KNX the new value will be written in the Modbus slave device using function code 06 2 If the Modbus function code to use for read is 01 and the function code to use for write is 05 which is also very common then select the function code 1 Read digital outputs in column Modbus Code and activate KNX flag W With this IntesisBox will use function code 01 for read the point in every polling cycle and whenever a write request for the point is received from KNX the new value will be written in the Modbus slave device using function code 05 3 If the Modbus function code to use for read and the function code to use for write are different than 01 05 or 03 06 sometimes found with specific devices then you have to declare two points in IntesisBox to perform the read and the write separately The way to configure this is better explained using an example Imagine you have a device in whi
