SDAT-MHS


2 Function and application

The position transmitter SDAT-MHS is intended for contactless recording of the piston position of mag

netically detectable drives and grippers. It is appropriate for use with Festo drives with T-slot (profile

slot 8) as well as round cylinders and tie-rod cylinders with mounting kits.

� Use the SDAT-MHS only for the suitable drives and grippers from Festo � www.festo.com/

catalogue.

The position transmitter SDAT-MHS records the magnetic field of the piston magnet and continuously

senses the piston movement in the sensing range.

Available output signals include:

– analogue current signal (4…20 mA)

– programmable switching output (24 V),

– IO-Link communication mode (� Chapter 2.3).

SDAT-MHS


2.1 Analogue output function

The analogue output provides a path-proportional output signal �4…20 mA in the sensing range of the

piston stroke.

– The analogue output signal can be scaled.

– The direction of increase of the analogue output signal can be inverted.

– In the switching output operating mode, the analogue position signal is made available parallel and

independent of the position value output of the switching output.

– The analogue output is switched off in the operating mode IO-Link.

Scaling of the analogue signal

The analogue output signal 4…20 mA is assigned as standard to the complete sensing range. If only a

part of the sensing range is used, the analogue value output can be scaled to the sensing range actually

used. Resolution and repetition accuracy are not improved through scaling.

The cylinder switch function consists of the switching travel and hysteresis. Hysteresis serves to sup

press switching signals in the event of fluctuations around the switching point.

– The teach value is the middle of the switching travel.

– Switching travel and hysteresis are not adjustable. For switching travel and hysteresis, values are

stored that correspond to a typical electronic cylinder switch in a typical drive.

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

– Teach point 2 establishes the size of the hysteresis.

2.2.4 Normally open (NO) and normally closed (NC) contacts

The switching logic normally open (NO) is set as standard. The function of the switching output is inver

ted through selection of the normally closed function (NC).

SDAT-MHS


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 pro

grammed. The switching output operating mode must be programmed actively via set-up mode (key)

(� Chapter 5.3).

– Either window comparator or cylinder switch function or hysteresis comparator programmable.

– Switching logic normally closed (NC) or normally open (NO) selectable.

– Programming via IO-Link protocol (channel BDC1) or operating key on the device.

– Display switching output ON: Yellow LED illuminated.

– Output signal 24 V DC (PNP).

Note

Even if the analogue output has been scaled, the switching output can still be pro

grammed over the entire sensing range.

2.4 IO-Link operating mode

In the IO-Link operating mode, programmed switching signals and the continuous position values (digit

ally coded analogue values) are transferred.

– There are 4 binary channels available, which can be programmed individually as window comparator

or cylinder switch or hysteresis comparator.

– The continuous position values are always transferred parallel and independent of the position

value output of the binary channels.

– Each channel is adjustable as 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 binary channels (� Chapter 10).

– Usage of unscreened standard cables of up to 20 m in length is possible.

– Device description file IODD for every device length � www.festo.com/sp.

– Parameters and functions in accordance with Smart-Sensor profile.

– Support of optional functions Block Parameterisation and Data Storage.

– Display IO-Link operation: Green LED flashes (1 Hz).

– Inversion of direction of process data values (PDV).

PDV is minimally (standard) or maximally (inverted) at the cable end of the sensor.

5.4 Block / unblock operating key

In the IO-Link mode, the operating key is automatically and always blocked.

In the switching output operating mode, the operating key is unlocked as standard. But it can be

blocked in the IO-Link mode for the switching output operating mode:

1. Produce IO-Link mode.

2. Select key block 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: Green LED flashes 3 seconds at 3 Hz.

– Yellow LED displays the current status of the switching output.

– Red LED is illuminated only when the piston is outside the sensing range.

5.5 Program IO-Link output

The IO-Link function cannot be set via the operating keys on the device. All settings for set-up, commis

sioning and parameterisation are made in the higher-level controller of the IO-Link master.

1. Load the device description file IODD (� www.festo.com/sp) belonging to the device into the

interpreter of the IO-Link masters.

2. Connect the IO-Link/switching output to the IO-Link master.

3. Program the device. Observe the instructions on this in the operating instructions of the IO-Link

masters.

Note

If the device detects an error during commissioning, it is displayed on the user interface

of the IO-Link master and the programming option is closed.

SDAT-MHS


6 Operation

6.1 Magnetic direction detection and correction

At initial start-up or after a reset to factory settings, the position sensor emits signals directly using the

currently detected magnetic direction.

The magnetic direction detection and, with it, the signal curve are corrected during ongoing operation

when the following cases occur:

– The position sensor was placed in operation in a position where a correct magnetic direction detec

tion was not possible (e.g. due to ferromagnetic materials near the sensor or within the drive or

gripper).

– The position sensor was turned 180° in the slot after the magnetic direction was recognised as

stable.

Note

Brief incorrect signals at the sensor output can occur if automatic correction of the

magnetic direction detection is required � Chapter 8.2.

If the device detects an error during the IO-Link operation a status signal is emitted on

the IO-Link master. The IO-Link/switching output is not blocked.

Malfunction Possible cause Remedy

Incorrect or unexpected

signals at the analogue

output or in the IO-Link

process data

Inappropriate drive Use an appropriate drive.

Device defective Replace device.

No operating voltage or

impermissible operating voltage

Comply with operating voltage

range.

Short circuit or overload at the

output

Eliminate short circuit/overload.

Magnetic objects in close

proximity to the position

transmitter

Prevent magnetic objects being in

close proximity.

Sensor/drive rotated by 180°

after initial start-up

Reset to factory settings (using

the operating key or via IO-Link).

Incorrect or unexpected signals

during initial start-up on grippers

or in top elements which are

partly ferromagnetic

At initial start-up, move gripper

jaws or pistons within the sensing

range (e.g. at both end positions).

Switching output does not

switch corresponding to

the settings

Short circuit or overload at the

output

Remedy short circuit / overload.

Device defective Replace device.

Settings cannot be edited Access protection active Release key (only possible via

IO-Link).
