Railbus Registers / Sub addresses
Communicating via the DIN Rail BUS Protocol, the DIN Rail LED-Dimmer implements two registers. Both registers have the same layout:
| SADR | 31 - 22 | 21 - 16 | 15 - 6 | 5 - 0 | |
|---|---|---|---|---|---|
| 0 | 0 | DIGIN | 0 | RELAIS | R |
| 0 | 0 | 0 | 0 | RELAIS | W |
| 1 | 0 | DIGIN | 0 | RELAIS | R |
| 1 | 0 | 0 | 0 | RELAIS | W |
On reading, the current status of all Pins is transmitted. If the first relais is on, bit 0 is set. If the second relais is on, bit 1 is set, and so on.
On writing only the 6 lowest bits are interpreted, and the relais set accordingly.
Writing to SADR 0 sets the relais only temporary. After a power-cycle all relais will be set to their initial state. This can be set by writing to SADR 1. In this case the state is set and stored in EEProm.
