Protocol description HSP5
1 Common
Target of the new protocol is a higher communication speed. This shall be reached by the following measures:
1. Higher baud rates (shorter telegrams)
2. Full Duplex data transfer (higher telegram throughput)
3. Hardware signals for telegram end (faster processing onto micro controllers)
4. Point to Point connection (no evaluation of the inverter address necessary)
5. Multi-master capable (no polling of important working conditions necessary)
6. No longer ASCII-coded (shorter telegrams)
1. Fundamental Telegram Structure
INV-ID-OP INV-ID-FU Service Set Selection, Parameter Address, BCC
Data, Acknowledgement (dep.on the
Service)
INV-ID-OP: bits. Identifying of communication cycles which are initiated by the operator. Rotating counter (1
- ). at INV-ID-FU 0.
INV-ID-FU: bits. Identifying of communication cycles which are initiated by the inverter. Rotating counter (1
- ). at INV-ID-OP 0.
Service: bits. Identifies the service to be executed. The upper two bits have special meanings.
bit 7: 0: => Request : => Response
bit 6: 0: => Read : => Write
Thereby write and read services are available.
Addr., Data: Contains the parameter addresses, the set information and the data. The content of this range is
dependent on the actual service.
BCC: Control byte. The value of this byte is an exclusive-or-calculation of the telegram bytes ahead.
