profile
1. Following start-up, the AS-Interface master (from master class 4) automatically replaces the ID object with the
S-7.A.5 slave.
S-7.A.5 slave replies with 6 bytes
1. Byte: Code
=
80 dez
2. Byte: Vendor ID (high)
= 120 dez
3. Byte: Vendor ID (low)
4. Byte: Device ID (high)
=
1 dez
5. Byte: Device ID (low)
6. Byte: 1 word
1 word input
=
34
dez
or with 2 Byte (Read Response not OK)
1. Byte: Code
= 144 dez
2. Byte: Error Code

dez (no error)
dez (illegal index)

dez (request not

dez (busy)
Master transmits 3 bytes:
1. Byte: Code
= 16 dez
2. Byte: Index
=
0 dez
3. Byte: Length =
5 dez
2. Then the following cyclical commands can be used:
Code = 0 (get cyclic data from Slave)
→
for feedback 0 – 100 %
Code = 1 (put cylic data to slave)
→
for set-point value 0 – 100 %
18)
Only for version with S-7.A.5 profile
