Example co
mmand 7, project slave parameters:
Note: The projected parameters can only be changed if the AS-i master is in config mode! Please
refer to command 2.
DP Master Request:
1. Byte: 16#07 (command number)
2. Byte: 16#42 (AS-i Master 1, Slave Nr. 2)
3. Byte: 16#0F (set projected parameters to 16#F)
4. Byte: 16#00 (not used)
DP-Gateway Response:
1. Byte: 16#07 (Copy of request)
2. Byte: 16#42 (Copy of request)
3. Byte: 16#0F (Copy of request)
4. Byte: 16#00 (not used)
Example command 8, read LAS(List of Active Slaves:
DP Master Request:
1. Byte: 16#08 (command number)
2. Byte: 16#42 (AS-i master 1, slave no. 2, corresponds to slaves 1...15 = group 1)
3. Byte: 16#00 (not used)
4. Byte: 16#00 (not used)
DP-Gateway Response:
1. Byte: 16#08 (Copy of request)
2. Byte: 16#42 (Copy of request)
3. Byte: 16#02 (slaves 8..15, that means slave 9 is activated)
4. Byte: 16#04 (slaves 1..7, that means slave 2 is activated)
The answer returns the slave list to which the requested slave belongs.

(*) -> LAS and LPS do not contain slave 0, therefore these values are set to 0 by default.
Example command 9, read LDS(List of Detected Slaves):
DP Master Request:
1. Byte: 16#09 (command number)
2. Byte: 16#50 (AS-i master 1, slave no. 16, corresponds to slaves 16...31 = group 2)
3. Byte: 16#00 (not used)
4. Byte: 16#00 (not used)
DP-Gateway Response:
1. Byte: 16#09 (Copy of request)
2. Byte: 16#50 (Copy of request)
3. Byte: 16#02 (Slaves 24..31, that means Slave 25 is detected)
4. Byte: 16#04 (Slaves 16...23, that means Slave 18 is detected)
