AS-i 3.0 Command Interface
Commands of the Command Interface
4.6.15
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, 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.
Information!
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.
