Process data (PD)
The variants of the BTL6-U10_-… cyclically output one or
more process data variables (PDV) with adjustable content
via the IO-Link interface. One process data variable
corresponds to one piece of device information and
consists of a signed 32-bit value.
Different amounts of information can be transferred for the
different variants:

Tab. 6-2: Process data
The following information can be mapped to the process
data variables by using the parameter
PD In Mapping
:
– Position of the 1st magnet
– Position of the 2nd magnet
– Velocity of the 1st magnet
– Velocity of the 2nd magnet
– Difference between magnets 1 and 2
– Current internal device temperature

IO-Link interface (continued)
In the event of an error, i.e. when no valid data can be
output, the respective process data variable is replaced
with the error value 0x7FFFFFFC. The data is only marked
as invalid via
PD Invalid Bit
if the device cannot deliver any
valid data at all.
The IO-Link functionality
PD Invalid Bit
is
handled differently by different IO-Link masters
(see manual for the master used).
Position values
The position values and difference are output with the
output resolution of 1 μm per digit and presents the
position of the magnet relative to the null point set at the
factory.
The measurement resolution of the BTL is 5 µm.
Intermediate values are not displayed in the
output value.
The factory default null value can be shifted within the
measuring range via the parameter
Null point offset
(see
on page
15).
Velocity values
The velocity values are output with a resolution of
0.5 mm/s per digit. The minimum movement speed is
1 mm/s.
Temperature values
Output in 1°C
