3.1 Construction

Electrical connection: The electrical connection is made via a connector (see Type code breakdown on page 23).

Housing: Aluminum housing containing the waveguide and processing electronics.

Mounting thread: We recommend assembling these transducers on the mounting thread:– BTL6-…-A/B: M18×1.5– BTL6-…-Y/Z: 3/4"-16UNFThe transducer with Ø 10.2 mm has an additional thread at the end of the rod to support larger nominal lengths.

Magnet: Defines the position to be measured on the waveguide. Magnets are available in various models and must be ordered separately (see Accessories on page 21).

Nominal length: To optimally adapt the transducer to the application, rods with a nominal length from 25 mm to 4572 mm are available.

Damping zone: Area at the end of the rod that cannot be used for measurements, but which may be passed over.

3.2 Function

The BTL6 transducer contains the waveguide which is protected by an outer stainless steel tube (rod). A magnet is moved along the waveguide. This magnet is connected to the system part whose position is to be determined. The magnet defines the position to be measured on the waveguide.

An internally generated INIT pulse interacts with the magnetic field of the magnet to generate a torsional wave in the waveguide which propagates at ultrasonic speed.

The component of the torsional wave which arrives at the end of the waveguide is absorbed in a damping zone to prevent reflection. The component of the torsional wave which arrives at the beginning of the waveguide is converted by a coil into an electrical signal. The travel time of the wave is used to calculate the position. The measuring value is output as a 32-bit value with a sign relative to the null point.

3.3 Number of magnets

Operation is possible with one or two magnets, where the number can be fixed or flexible (see Magnet Mode on page 18).

4.3 Installing the transducer

NOTICEInterference in functionImproper installation can compromise the function of the transducer and result in increased wear.

► The mounting surface of the transducer must make full contact with the supporting surface.

► The bore must be perfectly sealed (O-ring/flat seal).

► Make a mounting hole with thread (possibly with countersink for the O-ring) acc. to Fig. 4-3 or Fig. 4-4.

► Screw the transducer with mounting thread into the mounting hole (max. torque 100 Nm).

► Install the magnet (accessories). ► From 500 mm nominal length: support the rod and

tighten it at the end if necessary.

Suitable nuts for the mounting thread are available as accessories (see page 21).

4.3.1 Installation recommendation for hydraulic cylinders

If you seal the hole with a flat seal, the max. operating pressure will be reduced in accordance with the larger pressurized surface.If installing horizontally in a hydraulic cylinder (nominal lengths > 500 mm), we recommend affixing a slide element to protect the rod end from wear.

Dimensioning of the detailed solutions is the responsibility of the cylinder manufacturer.

The slide element material must be suitable for the appropriate load case, medium used, and application temperatures. E.g. Torlon, Teflon or bronze are all possible materials.

Fig. 4-5: Example 1, transducer installed with slide element

The slide element can be screwed on or bonded. ► Secure the screws so they cannot be loosened or lost. ► Select a suitable adhesive.

Fig. 4-6: Detailed view and top view of slide element

There must be a gap between the slide element and piston bore that is sufficiently large for the hydraulic oil to flow through.

Options for fixing the magnet:– Screws/bolts– Threaded ring– Press fitting– Notches (center punching)

If installed in a hydraulic cylinder, the magnet should not make contact with the rod.

The hole in the spacer ring must ensure optimum guidance of the rod by the slide element.

4.5 Cable routing

Defined ground!The transducer and the control cabinet must be at the same ground potential.

Magnetic fieldsThe position measuring system is a magnetostrictive system. It is important to maintain adequate distance between the transducer/holding cylinder and strong, external magnetic fields.

Cable routingDo not route the cable between the transducer, controller, and power supply near high voltage cables (inductive stray noise is possible).

The cable must be routed tension-free.

Cable lengthMax. cable length 20 m. Longer cables may be used if their construction, shielding and routing prevent noise interference.

5.1 Starting up the system

DANGERUncontrolled system movementWhen starting up, if the position measuring system is part of a closed loop system whose parameters have not yet been set, the system may perform uncontrolled movements. This could result in personal injury and equipment damage.

► Persons must keep away from the system’s hazardous zones.

► Startup must be performed only by trained technical personnel.

► Observe the safety instructions of the equipment or system manufacturer.

1. Check connections for tightness and correct polarity. Replace damaged connections.

2. Turn on the system.3. Check measured values and adjustable parameters

and readjust the transducer, if necessary.

Check for the correct values, especially after replacing the transducer or after repair by the manufacturer.

5.2 Operating notes

– Check the function of the position measuring system and all associated components on a regular basis.

– Take the position measuring system out of operation whenever there is a malfunction.

– Secure the system against unauthorized use.

6.1 Basic knowledge about IO-Link

GeneralIO-Link integrates conventional and intelligent sensors and actuators in automation systems and is intended as a communication standard below classic field buses. Field-bus-independent transfer uses communication systems that are already available (field buses or Ethernet-based systems).

IO-Link devices, such as sensors and actuators, are connected to the controlling system using a point-to-point connection via a gateway, the IO-Link master. The IO-Link devices are connected using commercially available unshielded standard sensor cables.

Communication is based on a standard UART protocol with a 24-V pulse modulation in half-duplex operation. This allows classic three-conductor physics.

ProtocolWith IO-Link communication, permanently defined frames are cyclically exchanged between the IO-Link master and the IO-Link device. In this protocol, both process and required data, such as parameters or diagnostic data, is transferred. The size and the type of the frame and cycle time used result from the combination of master and device features (see Device specification on page 13).

Cycle timeThe cycle time used (master cycle time) results from the minimum possible cycle time of the IO-Link device (min cycle time) and the minimum possible cycle time of the IO-Link master. When selecting the IO-Link master, please note that the larger value determines the cycle time used.

Protocol version 1.0 / 1.1In protocol version 1.0, process data larger than 2 bytes was transferred spread over multiple cycles.

From protocol version 1.1, all available process data is transferred in one frame. Thus, the cycle time (master cycle time) is identical to the process data cycle.

The BTL6-U101-… transducer is optimized for protocol version 1.1 and cycle time. Operating the IO-Link device on an IO-Link master with protocol version 1.0 results in longer transfer times (process data cycle ~ amount of process data x master cycle time).

Parameter managementA parameter manager that enables device parameters to be saved on the IO-Link master is defined in protocol version 1.1. When exchanging an IO-Link device, the parameter data of the previous IO-Link device can be taken over. The operation of this parameter manager is dependent on the IO-Link master and is explained in the corresponding description.

All parameters saved in the IO-Link master for parameter management are indicated correspondingly in Tab. 6-5 (see Parameter data on page 15).

Device functions and master gatewayThe functions of the transducer are described in detail in sections 6.2 to 6.7. How process, parameter and diagnostic data is implemented via the master gateway can be found in the instructions for the IO-Link master.

To flexibly adjust the basic communication parameters to the application, other device variants can be set (see parameter IO Link Variant config on page 17). Deviating settings can be found in the Tab. 6-8.

6.2.2 Transfer times

The transfer times for the transducer process data depends greatly on the master used. The maximum possible query frequency (Master Cycle Time) is determined by the master.

To be able to take advantage of full transducer performance, an IO-Link 1.1-capable master must be used.

If the master used supports the minimum cycle time set for the transducer, the transfer time can be determined as follows:– Transfer time, transducer to 1.0 Master =

PD volume × minCycleTime (8 ms for standard variant)– Transfer time, transducer to 1.1 Master =

minCycleTime (1 ms for standard variant)

6.3 Process data (PD)

The variants of the BTL6-U10_-… cyclically output one or more process data variables (PDV) with adjustable content via the IO-Link interface. One process data variable corresponds to one piece of device information and consists of a signed 32-bit value.

Different amounts of information can be transferred for the different variants:

IO-Link variant Number of bytes

PDV quantity

BTL-U100/BTL-U104 4 1

BTL-U101/BTL-U105 8 2

BTL-U102/BTL-U106 16 4

BTL-U103/BTL-U107 32 8

Tab. 6-2: Process data

The following information can be mapped to the process data variables by using the parameter PD In Mapping:– Position of the 1st magnet– Position of the 2nd magnet– Velocity of the 1st magnet– Velocity of the 2nd magnet– Difference between magnets 1 and 2– Current internal device temperature


In the event of an error, i.e. when no valid data can be output, the respective process data variable is replaced with the error value 0x7FFFFFFC. The data is only marked as invalid via PD Invalid Bit if the device cannot deliver any valid data at all.

The IO-Link functionality PD Invalid Bit is handled differently by different IO-Link masters (see manual for the master used).

Position valuesThe position values and difference are output with the output resolution of 1 μm per digit and presents the position of the magnet relative to the null point set at the factory.

The measurement resolution of the BTL6-U110-… transducer is 5 µm. Intermediate values are not displayed in the output value.

The factory default null value can be shifted within the measuring range via the parameter Null point offset (see Parameter data on page 15).

Velocity valuesThe velocity values are output with a resolution of 0.5 mm/s per digit. The minimum movement speed is 1 mm/s.

Temperature valuesOutput in 1°C

6.6.1 Device Access Locks

With this standard parameter, it is possible to activate or deactivate certain functions of the IO-Link device. With BTL6-U101-..., there is the option to lock the function of the parameter manager. To do so, bit 1 of the 2-byte value must be set to "1" (locked). In order to unlock the parameter manager, bit 1 is set to "0".

Bit 0 Lock parameter access(not supported)

Bit 1 Lock parameter management(supported)

Bit 2 Lock local parameterization(not supported)

Bit 3 Lock local user interface(not supported)

Bit 4 to 15 Reserved

Tab. 6-6: Lock parameter data

6.6.2 Profile Characteristic

This parameter indicates which profile is supported by the IO-Link device.Transducer BTL6-U101-… supports the smart sensor profile with the following function classes:– Subindex 1 (Profile Identifier -> DeviceProfileID):

0×0001 (Smart Sensor Profile)– Subindex 2 (Profile Identifier -> FunctionClassID):

0×8000 (Device Identification Objects)– Subindex 3 (Profile Identifier -> FunctionClassID):

0×8002 (ProcessDataVariable)

6.6.3 PD Input Descriptor

This parameter describes the composition of the process data variables used.Each process data variable can be reached via the corresponding subindex (subindex 1 for PDV1, subindex 2 for PDV2, etc.).Each subindex consists of 3 bytes:– 1st octet: 0x03, data type = signed integer– 2nd octet: 0x20, data size = 32 bits– 3rd octet: 0x00, bit offset = 0 (or a multiple of 32)The complete process data description for all PDVs can be read out via subindex 0. All blocks of 3 are lined up, beginning with the description of the highest value PDV.

6.6.4 Application Specific Tag

The Application Specific Tag makes it possible to assign the IO-Link device an arbitrary, max. 32-byte string. This can only be used for application-specific identification and applied in the parameter manager. The entire object is accessed via subindex 0.

6.6.5 Null point offset

Like the process data value, this parameter is a signed 32-bit decimal value. The programmed value must be within the null and end point in the valid measuring range. The value is deducted from the actual output value as a simple offset and therefore shifts the position of the magnet to an arbitrary point in the measuring range where the value 0 is output. Access takes place via subindex 0. The offset value can also be set and deleted via System Commands (see System Command on page 15).

6.6.6 Event Configuration

All application events can be switched off via the parameter Event Configuration so that they do not have to be output by the transducer.To activate or deactivate an event or the Invalid Bit function, the corresponding object can be addressed directly via the subindex and filled with a Boolean value (True = 0xFF, False = 0x00) (see Tab. 6-7).

Subindex Event

Subindex 1 Invalid Bit Function

Subindex 2 Position Error

Subindex 3 Position Warning End Point

Subindex 4 Position Warning Nullpoint

Subindex 5 Magnet Change

Tab. 6-7: Event Configuration

The events can also be configured using access via subindex 0. The last 5 bits are assigned to the sequence named in Tab. 6-7 and can simply be masked out.



6.6.7 Temperature

The following temperature values are output by the transducer as signed 8-bit values with the unit °C:– Current temperature (subindex 1)– Maximum temperature since power-up (subindex 2)– Minimum temperature since power-up (subindex 3)– Maximum temperature over the entire lifetime

(subindex 4)– Minimum temperature over the entire lifetime

(subindex 5)

The temperature sensor detects the temperature within the transducer. This is always higher than the ambient temperature.

6.6.8 IO Link Variant config

This parameter should only be used for initial parameterization of another device variant.

Using this parameter, the IO-Link variant or device configuration can be adjusted (see section Process data (PD) on page 14). Access takes place via subindex 0 with an 8-bit unsigned integer value.

The following device variants can be selected:

Tab. 6-8: Parameters of the different BTL6-U10_-… IO-Link device variants

This parameter changes the device’s basic communication settings. Changing parameters automatically triggers a device restart; the corresponding error messages in the superior system must be accepted.The parameter is not reset to factory settings via the Factory Reset function (see section 6.5).

Due to the special functionality, the parameter is not listed in the IO device description (IODD) and is not intended for data storage. For operation in a special IO-Link variant, Compatibility Mode is supported between the individual variants (see Basic knowledge about IO-Link on page 12).

6.6.10 Magnet Mode

The number of magnets can be fixed or flexible.

Setting a fixed number of magnetsWhen setting a fixed number of one or two magnets, the transducer continually checks the number of detected magnets. If this number does not match the presetting, the application enters an error state: all process data values are replaced with the error value.

Flexible magnet mode (FMM)In Flexible Magnet Mode, the number of magnets is flexible, allowing them to be changed during operation.The time when the magnet is added or removed is critical, since recording can then be re-adjusted and the contents of the process data values moved if necessary. In this case, a so-called diagnostic time is defined, which can be configured in the transducer. During this time, an error value is output for all process data variables and a corresponding diagnosis (warning) is transferred via IO-Link. After the diagnostic time lapses, the new application state is displayed.

Parameter structureThe parameter Magnet Mode consists of two 8-bit unsigned integer values: number of magnets and diagnostic time.

The following values can be set for the number of magnets:0 = Flexible number of magnets (1 or 2)1 = 1 magnet (fixed)2 = 2 magnets (fixed)

The diagnostic time is set in 4-ms increments as follows:1 = 4 ms2 = 8 ms…255 = 1.02 s

Access to the parameterAccess to the parameter is possible as follows:– Subindex 0: Byte 1 = diagnostic time

Byte 0 = FMM mode– Subindex 1: Magnet Mode– Subindex 2: Diagnostic time

6.6.11 PD In Mapping

This parameter allows the desired information to be mapped to the PDV (see Process data (PD) on page 14). Each PDV can be configured via the corresponding subindex.

Each PDV is assigned an 8-bit unsigned integer as mapping value. The following options can be set:

Value Designation

0x00 Position value, magnet 1

0x01 Position value, magnet 2

0x10 Velocity value, magnet 1

0x11 Velocity value, magnet 2

0xFD Empty module (output as value 0)

6.7 Diagnostic data

The transducer reports diagnostic data to the controlling system (see Tab. 6-12).

Event code Characteristic Meaning

0×8C10 Warning Process variable range overrun - Process Data uncertainThe magnet is located below the specified measuring range or below the null point. A process value is output but the data can exceed the linearity limits specified in the data sheet.

0×8C20 Error Measurement range overrun - Check applicationThe magnet is located outside of the measurable range and cannot be detected. No valid data is output. The transferred process data value is 0×7FFFFFFC or 2147483644.

0×8C30 Warning Process variable range underrun - Process Data uncertainThe magnet is located above the specified measuring range or above the end point. A process data value is output. The data can exceed the linearity limits specified in the data sheet.

0x8CA0 Warning Magnet Number Change - temporary error stateThe number of magnets was changed in FMM mode. For the duration of the set diagnostic time, an error is output and the process data is marked as invalid.
