IO-Link Program output
The IO-Link function cannot be set with the operating keys on the device. All set-
tings for set-up, commissioning and parameterisation are made in the higher-level
controller of the IO-Link master.

Analogue output
The analogue output provides an output signal 4 … 20 mA.
–
The output signal is proportional to the path of the piston stroke in the sensing
range.

Operation
7.1
Magnetic direction detection and magnetic direction correction
During initial commissioning or after a reset to factory settings, the position
transmitter outputs the signals directly using the currently detected magnetic
direction.
The magnetic direction detection and, with it, the signal curve are corrected
during continuing operation in the following cases:
–
The position transmitter was placed in operation in a position in which it was
not possible to detect a correct magnetic direction, e.g. due to ferromagnetic
materials near the sensor or within the drive or gripper.
–
The position transmitter was rotated 180° in the slot after the magnetic direc-
tion was detected as stable.
Brief error signals may be detected at the sensor output if automatic correction of
the magnetic direction detection is required
