®
The sensing device of the ADSI is a precision potentiometer. The position information is given
by an analog/digital converter output serialized as a data word. Data transmission takes
place by means of the signals CLOCK and DATA. The processing unit (PLC, Micro- com-
puter) sends pulse sequences which clock the data transmission with the required transfer
rate. With the first falling edge of a pulse sequence the position of the sensor is recorded and
stored. The following rising edges control the bit-by-bit A/D conversion, encoding and output
of the data word. After a delay time the next new position information will be transmitted.
