The objective of the study was to find a solution for a cheap and reliable data transmission system over the power line of a standard industrial power grid 220V for the implementation of projects of sensor and actuator local networks. The article considers the option of building a PLC path based on a ready-made solution using the TDA5051 modem chip from NXP Semiconductors. This modem uses ASK 1200 baud modulation. To test the operation of the PLC, prototypes of modules based on the STM32F103 microcontroller was assembled. The modem microcircuit adequately generates the carrier frequency signal, while the envelope filter is noticeable, and reduces the level of out-of-band emissions. Under ideal conditions, communication between communication modules was relatively stable, the share of lost packets was 11%. When testing communication in a real power grid, the attempt to transfer data was unsuccessful, the percentage of lost packets was 100%. Revealed very low noise immunity. The interference from the built-in power supply, based on the LNK306, was enough to completely interrupt communication. Another power supply plugged into the network also interrupts the communication.
