The proximity switch function consists of a switching path and hysteresis. Hysteresis serves to sup-
press switching signals in the event of fluctuations around the switching point.
–The teach-in value is the centre of the switching path.
–The switching path and the hysteresis are not adjustable. Values for the switching path and the
hysteresis are stored that correspond to a typical electronic proximity switch on a typical drive.

4.2.2.4 Switching logic
The switching logic normally open (NO) is set as the default. If the switching logic normally closed (NC)
is selected, the function of the switching output is inverted.
4.2.3 Switching output operating mode (SIO)
If the IO-Link/switching output is operated as a switching output, only 1 binary channel can be
programmed. The switching output operating mode must be programmed actively via the Set-up mode
è 6.2 Setting Set-up mode.
–The window comparator, the proximity switch or the hysteresis comparator function are program-
mable.
–The normally closed (NC) or the normally open (NO) switching logic can be selected.
–Programming via the IO-Link protocol (channel BDC1) or the operating key on the device.
–Display switching output ON: the yellow LED is on.
–Output signal 24 V DC (PNP).
Even if the analogue output has been scaled, the switching output can still be programmed over the
entire sensing range.
4.2.4 IO-Link operating mode
Programmed switching signals and the continuous position values (digitally coded analogue values)
are transferred in the IO-Link operating mode.

Operation
6.4.5 Block/unblock operating key
In IO-Link mode, the operating key is always blocked.
In the switching output operating mode, the operating key is unlocked by default. However, in the
IO-Link mode the operating key can be blocked for the switching output mode:
1. Start IO-Link communication.
2. Select key lock for switching output operating mode in the IO-Link parameter menu:
–Device access block
–Local user interface block
LED display with blocked operating key
–If the operating key is pressed, the green LED flashes for 3 s at 3 Hz.
–The yellow LED displays the current status of the switching output.
–The red LED only lights if the piston is outside the sensing range.
6.4.6 Programming IO-Link output
The IO-Link function cannot be set with the operating keys on the device. All settings for set-up,
commissioning and parameterisation are made in the higher-level controller of the IO-Link master.
1. Upload the IODD device description file belonging to the device to the interpreter of the IO-Link
master.
2. Connect the IO-Link/switching output to the IO-Link master.
3. Program the device è Operating instructions for the IO-Link master.
An error during commissioning is displayed on the user interface of the IO-Link master and the
programming option is blocked.
7Operation
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 opera-
tion 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 direction was detected as
stable.
Brief error signals may be detected at the sensor output if automatic correction of the magnetic
direction detection is required è 8.2 General malfunctions.
