4 Function
The position transmitter detects the magnetic field of the piston magnet and continuously senses the
piston movement in the sensing range. The position transmitter can be operated in one of the following operating modes:
– Cylinder switch with 2 programmable switching points (standard operation)
è 4.1 Cylinder switch operating mode.
– Position transmitter with IO-Link communication
è 4.2 Position transmitter operating mode (IO-Link).
In the case of active IO-Link communication (IO-Link master required), the SDAS-MHS switches automatically into the position transmitter operating mode.
Function
7Festo — SDAS-MHS — 2018-06

4.1 Cylinder switch operating mode
In the cylinder switch operating mode, 2 switching points can be programmed within the sensing
range.
– Operation using capacitive operating key
– Switching logic: normally open (NO)
– Output signal 24VDC (PNP or NPN)
– Marking on the housing indicates the centre of the sensing range.

4.2 Position transmitter operating mode (IO-Link)
In the position transmitter operating mode, programmed switching signals and the continuous position values (digitally coded analogue values) are transferred.
– Programming via IO-Link
– Device description file IODD èwww.festo.com/sp.
– Capacitive operating key is deactivated.
– Cylinder switches or window comparators or hysteresis comparators can be programmed individu-
ally on 4 switching channels.
– The continuous position values are always transferred in parallel with and independently of the
position value output of the switching channels.
– Each channel can be set to be normally closed (NC) or normally open (NO).
– Data transmission is serially and digitally coded in the IO-Link protocol.
– Process data: 12 bit for position data and 4 bit for switching channels è 10 Technical data.
– Unshielded standard cables of up to 20m in length can be used.
– Parameters and functions in accordance with Smart Sensor profile
– Support for the optional functions “Block parameterisation” and “Data storage”
– The direction of increase of the process data values (PDV) can be inverted. As delivered: lowest

4.3 Additional information on the operating modes
The binary data channels SSC1 and SSC2 for the position transmitter operating mode correspond to
the electrical switching outputs 1 and 2 for the cylinder switch operating mode.
Parameterising SSC1 and SSC2 via IO-Link makes it possible to use the window comparator and hysteresis comparator switching functions and the switching logic (NO/NC) in cylinder switch operating
mode too. Conversely, the switching points set in cylinder switch operating mode are directly available
in the position transmitter operating mode.
The switching logic for SSC1 set in the position transmitter operating mode applies to SSC1 and SSC2
in the cylinder switch operating mode, regardless of what has been set for SSC2.
An LED is available to display both switching outputs:
– Switching logic NC: the output signal for both switching outputs is AND-gated on the LED display.
– Switching logic NO: the output signal for both switching outputs is OR-gated on the LED display.

N x Press the capacitive operating key (in the example: 3x); max. 1s pause
between 2 consecutive presses
3s Hold the capacitive operating key pressed for at least 3s.
LED illuminated / LED flashing / LED OFF (in the example: yellow LED)
1) A switching point can only be set when the red LED is OFF. When the red
LED is flashing at 1.5Hz, the magnet is located in the region of the operational reserve. It is not possible to set a switching point. The operational
reserve is required for the safe setting of switching points in the edge
region. When the red LED is illuminated, the magnet is outside the sensing
range. It is not possible to set a switching point.
