Description
Data format
(Train of 26 pulses)
The data transmission takes place by means of the two signals CLOCK and DATA. The pro-
cessing unit (PLC, microcomputer) sends pulse sequences which clock the data transmissi-
on at the required transfer rate. With the first falling edge of the pulse sequence the position
of the sensor is recorded and stored. The following rising edges control the bit-by-bit transfer
of the data word. After a delay time the next new position information can be transwithted.

Note:
Extension of the cable length will reduce the
­maximum transmission rate.
The signals CLOCK/CLOCK and DATA/DATA
must be connected in a twisted pair cable,
­common shielded.
