11.4. Communication sequence for the version S-7.A.5
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 output +
1 word input
=
34
dez
or with 2 Byte (Read Response not OK)
1. Byte: Code = 144 dez
2. Byte: Error Code = 0

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 %
