19.8.5 Message Format for Measurement 0R0
The 0R0 sentence format is a proprietary format similar to NMEA 0183 rules. The 0R0
sentence contains essential measurement values of the compact weather station and is
designed for compatibility with existing installations.
The sentence is requested by the PB command for single measurement and PC for cyclic
transmission.
If certain measurement values are not available for the subtype of the individual weather
station the related value will be replaced by 999999. The same applies for measurement
values with status not “OK”.
The message is field oriented, with variable length. The fields are separated by ','.
