... main software of the monitoring application can be illustrated as a block diagram, which is implemented on the hardware controller, and it is presented in Fig. 3. The program starts with the definitions of the ports and pins used by the microcontroller. After the initialization of the communication, the data acquisition starts. The analog.read function reads the ADC port and returns a numeric value. One read of the converter, has a sample rate of about 10 kHz, and this reading speed is decreasing as multiple analog values are read in or if data computing time is increasing. The data computing is the main loop, where from the gathered information (the primary electrical parameters) the power and energy values are calculated. First the power calculation [10] in made in sampling loops, and after the power calculation, the energy calculations are done with a timer, started in the beginning of the loop, and it is always incrementing continuously. The communication with the GUI application and the display of the parameters are presented in the following section. The software solution is linked with the Level 2 of the application management structure, the represents the process supervisory ...
