The
subindex
is used to define the module to be set (from 1 to 16):
- Subindex = 0x01
set VALVE_STATUS on master module (address #0)
- Subindex = 0x02
set VALVE_STATUS on secondary module at address #1
-
…
- Subindex = 0x10
set VALVE_STATUS on secondary module at address #15
Byte 0
is used to define the operating mode of the valves according to the above table. Mode MD1
is the default operating mode.
