WMT700-compatible data message 24 outputs the wind measurement, self-diagnostics monitoring values, error code, and checksum in the following format:
$<WSA>,<WDA>,<WSG>,<WSL>,<TS>,<VH>,<VO>,<TTR>,<ER>,<CHK><CR><LF>
Name | Description |
---|---|
$ | Start of message delimiter |
<WSA> | Wind speed, average |
<WDA> | Wind direction, average |
<WSG> | Wind speed, gust |
<WSL> | Wind speed, lull |
<TS> | Sonic temperature |
<VH> | Heater voltage (same as operating voltage) |
<VO> | Operating voltage |
<TTR> | Temperature of transducers (average of 3 transducer temperatures) |
<ER> | Error code. The code is a bit field represented as a decimal number. Each bit corresponds to a status flag according to "device error code", Modbus register 0x0201. |
<CHK> | Checksum (8-bit XOR), see Checksum calculation, ASCII messages |
<CR> | Carriage return, ASCII code 0x0D |
<LF> | Line feed, ASCII code 0x0A |
