CONTROL AND DATA TRANSMISSION SYSTEM |
摘要 |
<p>The invention is based on the object of making available a control and data transmission system which uses simple components to permit current-modulated data transmission via a serial bus, and whose components can be used in a flexible way. For this purpose, the control and data transmission system (50) has a controllable bus terminating device (30) for impressing a predetermined working current into the bus (42, 44). Each subscriber (1, 2) has a D.C.-coupled transmitter (60) for generating and emitting control signals and data signals which modulate the working current, and a D.C.-coupled receiver (20) for sensing and evaluating the working current which is modulated by the control signals and data signals.</p> |
