Frequently Asked Questions - SDAT-MHS-M100-1L-SV-E-0.3-M8 Festo

How do I set the switching output (window comparator or proximity switch)?

Enter Set-up mode by pressing the operating key 3 times within 3 seconds. Then press once for window comparator, twice for proximity switch, or three times for hysteresis comparator. Move the piston to the desired switching points and press the key to teach them.

How can I scale the analogue output to a part of the sensing range?

In Set-up mode, press the operating key 5 times. Move the piston to the start point (teach point 1, assigned to 0 V) and press the key. Then move to the end point (teach point 2, assigned to 10 V) and press again. The direction of increase can be inverted by reversing the order of teach points.

What do the LEDs indicate during normal operation?

Green LED on: device ready, piston inside sensing range. Green flashing at 1 Hz: IO-Link mode active. Yellow LED on: switching output active. Red LED on: piston outside sensing range. If red LED is flashing, it indicates a hardware error.

How do I reset the device to factory settings?

Enter Set-up mode, then press the operating key 10 times. All three LEDs flash at 1 Hz. Press the key once more to confirm. The device resets to factory defaults: no switching function, normally open logic, full sensing range scaling.

What should I do if the switching output does not work?

Check for short circuit or overload at the output. Verify power supply (15-30 V DC). Ensure the piston is within the sensing range (red LED off). If the device is blocked, unlock via IO-Link or reset. If still faulty, replace the unit.

Can I use this sensor with any Festo drive?

Only with suitable Festo drives and grippers that have magnetic pistons. Do not place magnetic objects near the sensor. The drive must be compatible with T-slot mounting.

How do I invert the analogue output direction?

During scaling, set teach point 2 (10 V) on the cylinder axis before teach point 1 (0 V). This inverts the output signal direction without hardware changes.

What is the maximum cable length for IO-Link?

Unshielded standard cables up to 20 m length can be used. For longer distances, use shielded cables or consult Festo.

The red LED stays on even when the piston is inside the sensing range. What's wrong?

The magnetic field may be too weak or the drive is not suitable. Move the piston through the full range during initial commissioning. If issue persists, check for ferromagnetic materials near the sensor or rotate the sensor 180° and reset.

How do I change the switching logic from normally open (NO) to normally closed (NC)?

Enter Set-up mode, press the operating key 4 times. The yellow LED shows current logic: on = NC, off = NO. Press the key once to invert. The new logic is saved automatically.

4.2 Function

The position transmitter detects the magnetic field of the piston magnet and continuously senses the piston movement in the sensing range.

The following output signals are available:

• analogue voltage signal: 0 ... 10 V
• programmable switching output: 24 V
• IO-Link communication mode 4.2.4 IO-Link operating mode

4.2.1 Analogue output

The analogue output provides an output signal 0 ... 10 V.

• The output signal is proportional to the path of the piston stroke in the sensing range.
  -The output signal can be scaled.
  -The direction of increase of the analogue output signal can be inverted.
• The analogue output signal in the switching output operating mode is made available parallel and independent of the position value output of the switching output.
  -The analogue output is switched off in the IO-Link operating mode.

Fig. 2: Characteristic curve of the analogue output

X = maximum length of the sensing range

Signal Description	Range	1)
0 V	- IO-Link operation- Error, e.g. cable break, parameter error	-
0.5 V	- Piston is outside the sensing range after switching on the operating voltage	A, C
1 V	- The piston has left the sensing range in the direction of the falling output current	A
>1 V ... < 10 V	- Piston is within the sensing range B
10 V	- Piston has left the sensing range in the direction of the rising output voltage	C

1) Range Fig. 2, range A and C: red LED on
Tab. 2: Output signal of the analogue output

i

The analogue output is switched off during active IO-Link communication. The output voltage is 0 V.

Scaling of the analogue signal

The analogue output signal is assigned by default to the complete sensing range. If only a part of the sensing range is to be used, the analogue value output can be scaled to the sensing range in use. The resolution and the repetition accuracy are not improved by scaling.

Fig. 3: Scaling of the analogue signal using the SDAT-MHS-M160 as an example

① Teach-in point 1 ② Teach-in point 2

4.2.2 Switching functions and switching logic

4.2.2.1 Window comparator

Fig. 4: Window comparator

① Teach-in point 1 ② Teach-in point 2

Teach-in points 1 and 2 are linked to the window comparator function.

-The position of the teach points determines the window width.

-Hysteresis is not selectable or preset.

4.2.2.2 Proximity switch

Fig. 5: Proximity switch

1 Teach-in point

The proximity switch function consists of a switching path and hysteresis. Hysteresis serves to suppress 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.

4.2.2.3 Hysteresis comparator

Fig. 6: Hysteresis comparator

① Teach-in point 1 ② Teach-in point 2

Teach-in points 1 and 2 are linked to the hysteresis comparator function.

- Teach-in point 1 (ON) is the switch-on point, teach-in point 2 (OFF) is the reset point.

- Teach-in point 2 establishes the size of the hysteresis.

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

→ 6.2 Setting Set-up mode.
- The window comparator, the proximity switch or the hysteresis comparator function are programmable.
-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).

i

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.

Mounting

• Proximity switches, window comparators or hysteresis comparators can be programmed separately on 4 binary channels.
• The continuous position values are always transferred parallel and independently of the position value output of the binary channels.
• Every channel can be set to be normally closed (NC) or normally open (NO).
• The data transfer is serially and digitally coded in the IO-Link protocol.
• Process data: 12 bit for position data and 4 bit for binary channels 10 Technical data.
• Unshielded standard cables up to 20 m in length can be used.
• The device description file IODD for every device length www.festo.com/sp.
  -Parameters and function in accordance with Smart-Sensor profile.
• The optional block parameterisation and Data Storage functions are supported.
• IO-Link operation display: the green LED flashes.
  –The direction of the process data values (PDV) can be inverted.
  The PDVs are minimum (standard) or maximum (inverted) and end of the sensor cable.

7 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 direction was detected as stable.

i

Brief error signals may be detected at the sensor output if automatic correction of the magnetic direction detection is required 8.2 General malfunctions.
