FIELD: bus systems. SUBSTANCE: bus system has control unit, bus lines, and at least one peripheral device; control unit is designed for sending high- and low-priority messages to at least one peripheral device by means of sequence of binary states at high or low level of signal, signal amplitude between high and low levels of binary states of high-priority messages being greater than that of low-priority messages. EFFECT: enhanced reliability of separating messages having different priorities and, hence, different urgency. 18 cl, 9 dwg
