The native measurement cycle time of a sensor increases with the
stroke length. With extrapolation, the sensor is able to report data
faster than the native cycle time, independent of the stroke length of
the sensor. Without extrapolation, if data is requested faster than the
native cycle time, the last measured value is repeated.

and outputs (OUT) is performed from the perspective of the control-

the position and the velocity.

The internal linearization offers an improved linearity for an overall
higher accuracy of the position measurement. The internal lineariza-
tion is set for the sensor during production.

The Managing Node, usually an industrial PC or a PLC, controls
the communication in the network as master and sets the clock for
the synchronization of all devices. In a network there is only one

When moving the position magnet, the position and velocity values
increase in the measuring direction.

During the measurement cycle, the positions of every magnet on
the sensor are simultaneously reported. The velocity is continuously
calculated based on these changing position values as the magnets
are moved.
N
Node ID
The addressing of the devices in a POWERLINK network is done via
the node ID. Each node ID only exists once in a network. It can have
a value between 1 and 240 (while 240 is reserved for the Managing
Node). Meaning that a POWERLINK network can comprise up to 240
devices. With the R-Series
V
POWERLINK, the node ID (delivered
with node ID 1) can be set via the TempoLink smart assistant, for
example.

With the preset, a value is entered for the current position which is
to be output at this position in the future. The difference between the
entered value and the currently measured position is calculated as
an offset. (
