Example co
mmand 10, read LPF (List of Periphery Faults):
DP Master Request:
1. Byte: 16#0A (command number)
2. Byte: 16#51 (AS-i master 1, slave no. 17, 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#0A (Copy of request)
2. Byte: 16#51 (Copy of request)
3. Byte: 16#02 (Slaves 24..31, that means slave 25 has detected an external
peripheral fault)
4. Byte: 16#00 (slaves 16...23 have detected no periphery error)
Example command 11, read LPS (List of Projected Slaves):
DP Master Request:
1. Byte: 16#0B (command number)
2. Byte: 16#61 (AS-i master 1, slave no. 1B, (corresponds to slaves 1B...15B =
group 3)
3. Byte: 16#00 (not used)
4. Byte: 16#00 (not used)
DP-Gateway Response:
1. Byte: 16#0B (Copy of request)
2. Byte: 16#61 (Copy of request)
3. Byte: 16#02 (slaves 8B..15B, that means slave 9B is projected)
4. Byte: 16#04 (slaves 1B...7B, that means slave 2B is projected)
Example command 13, read error counter:
DP Master Request:
1. Byte: 16#0D (command number)
2. Byte: 16#41 (AS-i master 1, slave no. 1)
3. Byte: 16#00 (not used)
4. Byte: 16#00 (not used)
DP-Gateway Response:
1. Byte: 16#0D (Copy of request)
2. Byte: 16#41 (Copy of request)
3. Byte: 16#14 (20 erroneous telegrams have been sent since the start of current data
transfer with slave 1)
4. Byte: 16#00 (not used)
Example command 14, read configuration error counter:
DP Master Request:
1. Byte: 16#0E (command number)
2. Byte: 16#40 (AS-i Master 1)
3. Byte: 16#00 (not used)
4. Byte: 16#00 (not used)
DP-Gateway Response:
1. Byte: 16#0E (Copy of request)
2. Byte: 16#40 (Copy of request)
3. Byte: 16# (3 configuration errors have occurred since master 1 started current data
transfer)
4. Byte: 16#00 (not used)
