20.6.5 Additional Measurement Commands
With the additional measurement commands
aM1! … aM3!
aMC1! … aMC3!
(M command, data transmission with CRC)
aC1! … aC3!
aCC1! … aCC3!
(C command, data transmission with CRC)
the complete range of measurement data of the
Ventus
, as defined for the UMB protocol, is also
available in a SDI-12 environment.
The measurement values are grouped according to sensor types.
As for the base data, an M command only permits to request up to 9 measurement values. With
C commands, up to 20 values are available.
The buffer assignment defined below is thus structured in a way, that the resp. M command
uses the D0 and D1 buffers. If more values are available for the sensor type, the C command
will also fill the buffers D2 to D4 (if required)
M1 / C1

M: 4 Values
C: 4 Values
