6 2 Safety 2.1 Intended use The BTL6 Micropulse Transducer, together with a machine controller (e.g. PLC) and an IO-Link master, comprises a position measuring system. It is intended to be installed into a machine or system. Flawless function in accordance with the specifications in the technical data is ensured only when using original BALLUFF accessories. Use of any other components will void the warranty. Opening the transducer or non-approved use are not permitted and will result in the loss of warranty and liability claims against the manufacturer. 2.2 General safety notes for the position measuring system Installation and startup may only be performed by trained specialists with basic electrical knowledge. Qualified personnel are those who can recognize possible hazards and institute the appropriate safety measures due to their professional training, knowledge, and experience as well as their understanding of the relevant regulations pertaining to the work to be done. The operator is responsible for ensuring that local safety regulations are observed. In particular, the operator must take steps to ensure that a defect in the position measuring system will not result in hazards to persons or equipment. If defects and unresolvable faults occur in the transducer, it should be taken out of service and secured against unauthorized use. 2.3 Explanation of the warnings Always observe the warnings in these instructions and the measures described to avoid hazards. The warnings used here contain various signal words and are structured as follows: SIGNAL WORD Hazard type and source Consequences if not complied with Measures to avoid hazards The individual signal words mean: NOTICE Identifies a hazard that could damage or destroy the product. DANGER The general warning symbol in conjunction with the signal word DANGER identifies a hazard which, if not avoided, will certainly result in death or serious injury. 2.4 Disposal Observe the national regulations for disposal. 6 english

Housing: Aluminum housing containing the waveguide and processing electronics. Mounting thread: We recommend assembling these transducers on the mounting thread: BTL6- -A/B: M BTL6- -Y/Z: 3/4"-16UNF The 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). english 7

8 4 Installation and connection 4.1 Installation guidelines Non-magnetizable material Non-magnetizable material 4.2 Preparing for installation Installation note: We recommend using nonmagnetizable material to mount the transducer and magnet. Magnet min. Ø D2 1) 1) Min. Ø D2 = Minimum diameter of the bore (see Tab. 4-1) Fig. 4-1: Installation in non-magnetizable material Magnetizable material If using magnetizable material, the transducer must be protected against magnetic interference through suitable measures (e.g. spacer ring made of non-magnetizable material, a suitable distance from strong external magnetic fields). Horizontal assembly: For horizontal assembly with nominal lengths > 500 mm, support the rod and tighten it at the end if necessary. Hydraulic cylinder: If installed in a hydraulic cylinder, ensure that the minimum value for the bore diameter of the support piston is complied with (see Tab. 4-1). Mounting hole: The transducer comes with an M (ISO) or 3/4"-16UNF (SAE) mounting thread. Depending on the version, a mounting hole must be made before assembly.

9 4 Installation and connection (continued) 4.3 Installing the transducer NOTICE Interference in function Improper 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 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). The slide element can be screwed on or bonded. Secure the screws so they cannot be loosened or lost. Select a suitable adhesive. Piston rod Fig. 4-6: Slide element Rod 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) Slide surface Flow gap 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. 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. Magnet Fixing of magnet 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.

It is important to maintain adequate distance between the transducer/holding cylinder and strong, external magnetic fields. Cable routing Do 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 length Max. cable length 20 m. Longer cables may be used if their construction, shielding and routing prevent noise interference. but not to the shield.

11 5 Startup 5.1 Starting up the system DANGER Uncontrolled system movement When 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. english 11

12 6 IO-Link interface 6.1 Basic knowledge about IO-Link General IO-Link integrates conventional and intelligent sensors and actuators in automation systems and is intended as a communication standard below classic field buses. Fieldbus-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. Protocol With 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). Parameter management A 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 gateway The 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. Cycle time The 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 / 1.1 In 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). 12 english

13 6 IO-Link interface (continued) 6.2 Device specification Communication parameters Tab. 6-1 describes the basic IO-Link specification for standard variant BTL6-U101- Specification IO-Link Description Value Transfer rate COM kbaud Minimum cycle time of device min cycle time 0 0A (1ms) Frame specification: Amount of preoperate data required Amount of operate data required ISDU M-sequence capability: Preoperate M-sequence type Operate M-sequence type ISDU supported 0 1B 2 bytes 2 bytes Supported IO-Link protocol version Revision ID 0 11 (version 1.1) Amount of process data from the device to the ProcessDataIn 0 87 (8 bytes) master Amount of process data from the master to the ProcessDataOut 0 00 (0 bits) device Manufacturer ID Vendor ID Device identification Device ID (see Tab. 6-8) Tab. 6-1: Device specification for standard variant BTL6-U101- 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 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) english 13

14 6 IO-Link interface (continued) 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 PDV quantity bytes BTL-U100/BTL-U BTL-U101/BTL-U BTL-U102/BTL-U BTL-U103/BTL-U 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 values The 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 values The velocity values are output with a resolution of 0.5 mm/s per digit. The minimum movement speed is 1 mm/s.

16 6 IO-Link interface (continued) Device Access Locks With this standard parameter, it is possible to activate or deactivate certain functions of the IO-Link device. With BTL6-U , 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" 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. Bit 0 Bit 1 Bit 2 Bit 3 Bit 4 to 15 Lock parameter access (not supported) Lock parameter management (supported) Lock local parameterization (not supported) Lock local user interface (not supported) Reserved 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). Tab. 6-6: Lock parameter data 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): (Smart Sensor Profile) Subindex 2 (Profile Identifier -> FunctionClassID): (Device Identification Objects) Subindex 3 (Profile Identifier -> FunctionClassID): (ProcessDataVariable) 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 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 Subindex 1 Subindex 2 Subindex 3 Subindex 4 Subindex 5 Tab. 6-7: Event Invalid Bit Function Position Error Position Warning End Point Position Warning Nullpoint Magnet Change 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. 16 english

17 6 IO-Link interface (continued) 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 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: Value Product name Device ID Product ID 1) Transfer rate Amount of process data device master Min. cycle time 0x00 BTL6-U100-0x BTL6ABYZIOL000 COM3 0x83 (4 bytes) 0x0A (1 ms) 0x01 BTL6-U101-2) 0x BTL6ABYZIOL001 COM3 0x87 (8 bytes) 0x0A (1 ms) 0x02 BTL6-U102-0x BTL6ABYZIOL002 COM3 0x8F (16 bytes) 0x0F (1.5 ms) 0x03 BTL6-U103-0x BTL6ABYZIOL003 COM3 0x9F (32 bytes) 0x14 (2 ms) 0x04 BTL6-U104-0x BTL6ABYZIOL004 COM2 0x83 (4 bytes) 0x1E (3 ms) 0x05 BTL6-U105-0x BTL6ABYZIOL005 COM2 0x87 (8 bytes) 0x28 (4 ms) 0x06 BTL6-U106-0x BTL6ABYZIOL006 COM2 0x8F (16 bytes) 0x40 (6.4 ms) 0x07 BTL6-U107-0x BTL6ABYZIOL007 COM2 0x9F (32 bytes) 0x4A (10.4 ms) 1) ABYZ stands for the respective housing style 2) Standard variant, see Tab. 6-1 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). english 17

18 6 IO-Link interface (continued) Output Characteristic This parameter determines the output function of the transducer with rising or falling characteristic curve. Access takes place via subindex 0. Value 0x00 (FALSE) 0xFF (TRUE) 1) 1) Default setting Tab. 6-9: Output function Falling (null point at the end of the rod) Rising (null point at the electronic head) Output Characteristic Magnet Mode The number of magnets can be fixed or flexible. Setting a fixed number of magnets When 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 structure The 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) Access to the parameter Access 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 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) Tab. 6-10: PD In Mapping Error messages Certain error messages are stored for failed parameterization: Error code Error message Index not available Subindex not available Service temporarily not available Value out of Range Parameter Length overrun Parameter Length underrun Function temporarily unavailable Tab. 6-11: IO-Link specification error messages The diagnostic time is set in 4-ms increments as follows: 1 = 4 ms 2 = 8 ms 255 = 1.02 s 18 english
