<p>The paper reviews the use of multidimensional measuring and control variables and their modern hardware and software in the conversion of power sources to secondary signals in the power supply processes of computing and info-communication devices, the principles of monitoring them, and receiving signals to ensure smooth and quality operation of devices. It also elucidates the principle of construction, model and software of working and transmitting media on an appropriate basis. The developed power supply control device is based on the ongoing processes and functional modules selected when the device was assembled. According to the main objective of the study, a monitoring algorithm and software package were developed based on the built-in system architecture. The implemented model was used to describe integration processes taking place between the hardware and software for monitoring, in detail. The research enabled the development and introduction of models of the IDEF database destined for the collection and processing of statistical data in monitoring processes of a software package. Practical results from the generation of sources of electricity and its use in enterprises by month, year and day, are presented in the form of graphs and tables.</p>
