5.3.6 Process data transmission in IO-Link operation
In 3-wire operation when the IO-Link interface is used, all diagnostic cases are
described in the IODD of the unit are transmitted� Depending on the setting of
drEd and dOU1 a signal is provided that corresponds to the physical switching
output�
In addition to the diagnostic message the IO-Link interface provides 3 process
values:
(1) Mean value from the individual values of both sensor elements
(2) Measured value of the Pt 1000 sensor element
(3) Measured value of the NTC sensor element
In case of an event the process value transmission is interrupted according to
table 5:

Measured value is displayed� (If one sensor element fails: temperature = measured
value of the remaining sensor element�)
—
Measured value of the remaining sensor element continues to be provided�
For the failed element, "NoData" is displayed instead of the measured value�
x
"Invalid" is provided instead of the measured value�
