SET_DATA_EX:
Change Slave Address (SLAVE_ADDR):
With this call, the AS-i address of an AS-i slave can be modified.
This call is mainly used to add a new AS-i slave with the default address "0" to the
AS-Interface. In this case, the address is changed from "AS-i slave address old" = 0
to "AS-i slave address new”.
This change can only be made when the following conditions are fulfilled:
1. An AS-i slave with “AS-i slave address old” exists.
2. If the old AS-i slave address is not equal to 0, then an AS-i slave with address "0"
cannot be connected at the same time.
3. The "AS-i slave address new" must have a valid value.
4. An AS-i slave with "AS-i slave address new" must not exist.
Note: When the AS-i slave address is changed, the AS-i slave is not reset, in other
words, the output data of the AS-i slave are retained until new data are received at
the new address.
