Three example programs are available for the TempVue 20. The SDI-12 program uses the R0! SDI-12 instruction to retrieve the temperature measurement. A basic Modbus program retrieves both the Celsius and Fahrenheit temperature measurements from the TempVue 20. The advanced Modbus program retrieves the instantaneous measurements, averages, minimums, maximums, measurement period, red flags, serial number, operating system version, and model ID.
These programs are written for the CR1000X data logger, but programs for the other data loggers will be similar.
