The task of the DEMASole software is primarily to retrieve data from online stations automatically at fixed, predefined times. Critical time shifts, e.g. the transition from summer to winter time, are automatically adjusted by DEMASole. Upon request, DEMASole converts the read-out data files into a specific or suitable output format and stores them in a freely definable destination directory. From there, the data from external programs (e.g. DEMASdb) or process control systems can be received and processed.
