FIELD: instrument making.
SUBSTANCE: invention relates to generation of datagrams for controlling at least one load module or a lamp by means of control device connected to a phase conductor of source of supply voltage via a load line. According to invention brightness information is transmitted by phase undercut or phase cut, wherein said voltage signal is modulated by a datagram, wherein a data bit is transmitted to each full wave voltage. Depending on recognised type of load - capacitive, inductive, ohmic - information or data bits are applied accordingly.
EFFECT: technical result consists in reduction of noise generated by a load line.
