Identification System is a non-contact read-only system. The compact processor consists of processing circuitry with a fixed read head. The system may be used to read information which has been permanently programmed into the data carrier and to send current status messages to the controller. The main components of the BIS L-409-... Identification System are: – Processor, – read head, – data carriers. Data transmission to the controlling system is accomplished using an IO-Link Master. Connection to IO-Link Master Data carrier BIS L-2… Fig. 8: Schematic representation of an identification system The data carrier is an autonomous unit which is supplied with power by the read head. The read head continuously sends a carrier signal which is picked up by the data carrier from within a certain distance. As soon as the data carrier is powered up by the carrier signal, a static read operation takes place. The processor manages the data transfer between read head and data carrier, serves as a buffer storage device, and sends the data to the host controller. The data are passed to the IO-Link Master using IO-Link protocol, and the Master then passes them to the controlling system. Host systems may be the following: – A control computer (e.g. industrial PC), – a PLC. The main areas of application are: – In production for controlling material flow (e.g. in model-specific processes), in workpiece transport with conveying systems, for acquiring safety-relevant data. – warehousing for monitoring material movement, – transportation, and – conveying technology. www.balluff.com 13 BIS L-409 IO-Link Device Processor Basic knowledge 4.2 System topology Fig. 9: BIS L-409… topology 14 PLC PC ProfiBus IO-Link Master Processors BIS L-409… BIS L-409 IO-Link Device Processor Basic knowledge 4.3 Read distance/ offset To ensure that data carriers are recognized without error and the data can be reliably read, do not exceed a maximum distance and maximum offset between the data carriers and read heads (see “Technical Data” starting page 16). The “distance” specification refers to the maximum distance from the data carrier to the sensing surface of the read head. The “offset” specification indicates the maximum offset between the center axis of the data carrier and the center axis of the sensing surface. Data carriers can only be reliably recognized and the data reliably read within the permissible read distance and offset. In the border area an unstable condition may occur, so that a data carrier is alternately recognized and lost. Data carrier recognition is indicated by an LED on the device (“TP – Tag Present”, see “Technical Data” starting page 16). At the same time the CP bit is set in the input buffer (“CP – Codetag Present”, see “Process Data” starting page 42). 4.4 Product description Processor BIS L-409-045-…-07-S4: – Plastic housing, – circular connector terminations, – one read head connected, – the read head suitable for dynamic or static operation, – data carrier is powered by the read head using a carrier signal. 4.5 Data security In order to ensure data integrity, data transmission between the data carrier and processor can be monitored using a check procedure. In the processor a CRC_16 data check can be configured. If the CRC check is enabled, the data carrier data are checked using a 2-byte CRC_16 checksum. If the checksum does not agree with the checked data, an error message is sent. Note The CRC_16 data check can only be used with data carriers of type BIS L-10X-05/L The data carriers must be initialized using a BIS L-60_ _ processor and the BISCOMRW.EXE PC software or a portable reader BIS L-81_ (refer to the User's guide for the corresponding device for this procedure). 4.6 IO-Link basic knowledge The manufacturer-specific standard IO-Link sends not only the actual process signal, but also all relevant parameter and diagnostics data on the process level over a single standard cable. Communication is based on a standard UART protocol with 24V pulse modulation; no separate power supply is required. Connection is possible using a 2-conductor or 3-conductor cable. Advantages of IO-Link: – Uniform, simple wiring of different devices – Controlling system can be used to change the device parameters – Remote querying of diagnostics information is possible – Centralized data retention of the device parameters is possible www.balluff.com 15 BIS L-409 IO-Link Device Processor Technical Data 41 BIS L-409-045001-07-S4 Dimensions Fig. 10: Dimensions for BIS L-409-045-001-07-S4 processor [mm] Characteristic data Mechanical data 16 Clear zone BIS L-409-045-001-07-S4 Characteristic data when used with data carriers (installed in clear zone) When v = 0 (static) Distance [mm] read Offset from center axis at distance: [mm] 0 -

In critical applications a pre-test is recommended! 26 BIS L-409 IO-Link Device Processor Installation Orienting the read head The read head of the processor consists of a read head module and read head carrier. The sensing face of the read head can be positioned as desired (see Fig. 19). Rotating the sensing face from front to up or to the side: ► Unscrew both screws (6) on the read head carrier (7). ► Rotate read head module (2) by 180°. ► Tighten both screws (6). Rotating the read head: ► Loosen locking screw (3). ► Turn read head to the desired position. ⇒ The read head can be rotated steplessly by 270°. ► Tighten locking screw (3). Note The read head module is protected against overtightening. The read head modules are not interchangeable.

Mixed use of traditional and intelligent devices is possible with no additional effort. IO-Link is intended as a communications standard below the traditional fieldbus level. Fieldbusneutral IO-Link transmission uses existing communications systems (fieldbuses or Ethernetbased systems). The actuators and sensors are connected in point-to-point using conventional unshielded cables. IO-Link devices can send application-specific parameters and data (e.g. diagnostics data) using a serial communications procedure. Flexible telegrams are possible for sending larger quantities of data. Communication is based on a standard UART protocol with 24V pulse modulation. Only one data line is used, which carries both the controller as well as the device telegram. This means that conventional 3-conductor physics is possible. IO-Link supports both communication mode as well as standard IO mode (SIO). Standard IO provides a switching signal on the communication line such as used by normal binary switching sensors. This mode is only possible with devices using 3-conductor connection technology. �� � � � � ��� �� Fig. 22: ������� ����������� 3-conductor physics of IO-Link The BIS L-409-... supports both modes. In SIO mode the signal “Data carrier in range” (24V) and “No data carrier in range” (0 V) is made available to the host system as a switching signal. If the BIS L-409… is not used with an IO-Link Master and without triggering IO-Link communication, it works in SIO mode and can be operated on a digital input. Communications mode The BIS L-409-... works in communication mode with Frame Type 1. In this transmission type 2 bytes of process data or required data are sent per frame (data block). This can take place either from IO-Link Master to device or vice-versa. Process data are the application-specific data, and required data may contain parameters, service or diagnostic data. Interleave mode So-called “Interleave Mode” makes it possible to send larger quantities of data. There multiple Type 1 frames must be combined into a sequencer. One frame with process data and one with required data are sent in alternation. With the BIS L-409 a sequence consists of 32 individual frames. 8 bytes of process data are sent in each direction per sequence. These process data are shown in greater detail in Section 10.4 “Protocol sequence” on page 42. www.balluff.com 29 BIS L-409 IO-Link Device Processor IO-Link Basics 7.2 Process data container The IO-Link protocol provides a process data container 32 bytes in size. Addressing is done in the command byte which the IO-Link Master sends. When process data are sent, addressing is directly to the sub-indices 00hex … 1Fhex. The BIS L-409-… processes 8 bytes of input and 8 bytes of output data (input buffer/output buffer). The process data are mapped to the first 8 bytes of the process data container (subindices 00hex…07hex). BIS L-409 IO-Link Device Subaddress 00hex ⇒ 00hex ... ... ... IO-Link protocol Subaddress 07hex ⇒ 07hex ... 08hex 1Fhex 7.3 Direct parameter page The Direct Parameter Page (DPP) contains 32 bytes of application-specific parameters and parameters for setting IO-Link communication. This corresponds to the first two pages of the Service Protocol Data Unit (SPDU) with 16 bytes each. Although the SPDU of the BIS L-409 devices is not supported, access to the DPP is made via Index, Subindex and length (in bytes) of the SPDU. With Subindex 0 all 16 bytes of the Index can be accessed; the length determines how many parameters are read or written. With a Subindex > 0 a particular element of the Index is accessed, and the length specification is not used. Specification of these values depends on the IO-Link Master and the controller. The most important parameters are summarized in the following table. Each parameter has a data width of 1 byte.

Note The values of the unused device-specific parameters 13hex to 1Bhex must be set to “0”. Saving the parameters 32 The configured parameters are immediately valid as soon as they are set. However, if there is a power loss the user-defined settings will be lost. The device is restarted with the factory settings, and any other parameter setting needs to be made again. BIS L-409 IO-Link Device Processor Setting the processor parameters 8.2 Parameterization data mapping CRC check Address 10hex, CRC_16 check The CRC check is a procedure for determining a check value in order to be able to recognize data transmission errors. If the CRC check is activated, an error message is sent when a CRC error is detected. (If the parameter CRC_16 data check is set, then in addition to the data carrier data, a 2-byte CRC_16 checksum is checked (see “Data integrity” on page 15). The data compare counter is automatically set to one-time reading. Detection of a data carrier arriving in the read zone then takes a maximum of 70 ms. Note The CRC_16 data check can only be used with data carriers of type BIS L-10X-05/L. The data carriers must be initialized using a BIS L-60_ _ processor and the BISCOMRW.EXE PC software or a portable reader BIS L-81_ (refer to the User's guide for the corresponding device for this procedure). Checksum The checksum is written to the data carrier as 2 bytes of information. This means 2 bytes of user data per block are sacrificed. 1 byte, Address 10hex MSB LSB (not relevant) 1/0 Bit 0 (LSB) = 0: no CRC check (default setting) Bit 0 (LSB) = 1: CRC Check Data carrier Address 11hex, BIS L-10x-05 Note If type BIS L-10X-05 data carriers are used, parameter “BIS L-10x-05” must be activated. 1 byte, Address 11hex MSB (not relevant) LSB 1/0 Bit 0 (LSB) = 0: No type BIS L-10x-05 data carrier is used (default setting) Bit 0 (LSB) = 1: A type BIS L-10x-05 data carrier is used www.balluff.com 33 BIS L-409 IO-Link Device Processor Setting the processor parameters Data comparison counter Address 12hex, data comparison counter Using this parameter you can increase data integrity if the CRC_16 checksum is not used. The processor reads the data carrier data multiple times within a read operation. The processor stores and compares the data. Once the data carrier is recognized, the processor releases the data. From 1 to 10 read repetitions can be set in the “Data comparison counter” field. 1 byte, Address 12hex MSB (not relevant) LSB Value range: 01hex…0Ahex Bit 0 … 3: Permissible value range 01hex … 0Ahex (decimal 1 … 10) Default setting: 02hex (decimal: 2) The decimal value is copied directly to the program. If an input value lies outside the permitted value range, the default setting of 2 comparisons is used. 34 BIS L-409 IO-Link Device Processor Startup 9.1 Project administration GSD file In project administration of fieldbus devices, a physical device is mapped as a modular system consisting of a head module and multiple data modules. The device data required for project planning are stored in GSD files (Generic Station Description). The GSD files are made available by the vendors of the IO-Link Masters. The GSD files for Balluff IO-Link Masters are available on the Internet at “www.balluff.com/software” for downloading. The data modules for an IO-Link device are shown in the project administration software by port. The GSD file provides the possible data modules (inputs or outputs of various data width). For configuring the IO-Link device the appropriate data modules are assigned to a particular port. Head module First the head module is inserted into the configuration. The head module is coded according to the special identification format. head modules in this coding are used for identification and parameter setting and have a data width of 2 bytes input of 2 bytes input/output data. Data modules The data modules are arranged onto the head module in order of the slots for ports/PINs. 9.2 Integration into project administration software To integrate a BIS L-409 IO-Link device the following steps a generally required: 1. Load the GSD file for the IO-Link Master into the hardware configuration of the host system. 2. Insert the data module “Input 8 bytes/Output 8 bytes” (IOL_I/O_8/8_Byte) for the used IO-Link port (Port X, Pin 4). ⇒ This assigns the start addresses of the input and output data. The input and output data can, as described in Section 10, be used for operating the BIS L-409-.... 9.3 Integration example Integration of a BIS L-409-IO-Link-Device is shown using the example of a BNI-PBS-IO-LinkMaster. In the example a Siemens S7 with “SIMATIC-MANAGER” program and project administration software is used.

Identification System is a non-contact read-only system. The compact processor consists of processing circuitry with a fixed read head. The system may be used to read information which has been permanently programmed into the data carrier and to send current status messages to the controller. The main components of the BIS L-409-... Identification System are: – Processor, – read head, – data carriers. Connection to IO-Link Master Data carrier BIS L-2… Fig. 32: Schematic representation of an identification system The data carrier is an autonomous unit which is supplied with power by the read head. The read head continuously sends a carrier signal which is picked up by the data carrier from within a certain distance. Once the data carrier is powered, a static read operation takes place. The processor manages the data transfer between read head and data carrier, serves as a buffer storage device, and sends the data to the host controller. The data are passed to the IO-Link Master using IO-Link protocol, and the Master then passes them to the controlling system. Host systems may be the following: – A control computer (e.g. industrial PC), – a PLC. 10.2 Operating mode www.balluff.com The BIS L-409-... supports cyclical data exchange via IO-Link protocol and standard IO mode. Recognition of a data carrier (Codetag Present, 24 V) or no data carrier (0 V) is sent on the data line C/Q as a digital switching signal. In cyclical data exchange the BIS L-409-... cyclically sends read data to the controller. It is also possible to read or enter parameter data in this mode. 41 BIS L-409 IO-Link Device Processor 10 Device Function 10.3 Process data The start addresses of the input and output data are assigned in the hardware configuration for the host system. The BIS L-409-... uses 8 bytes of input and 8 bytes of output data, with assignment as described in the following. Subaddress 00hex corresponds to the respective start address of the hardware configuration. Output/Input buffer The BIS L-409-... provides two fields for sending commands and data between the BIS L-409… and the host system: – Output buffer – Input buffer These fields are embedded into the process data transmission via the IO-Link Master. As described above, 8 bytes of process data are sent in each direction. The map of this process data is described below: Output buffer: Bit-No. Subaddress 00hex - 1st bit header KA GR KA GR 01hex 02hex 03hex 04hex 05hex 06hex 07hex - 2nd bit header Explanations for output buffer: Subaddress Bit name 00hex 1st bit header 07hex Function description KA Head on/off 1 = Head off (read head turned off) 0 = Head on (read head operating) GR Ground state 1 = Software-Reset - causes the BIS to go to the ground state 0 = Normal operation 2. bit header KA, GR 42 Meaning If 1st and 2nd bit headers agree, there are valid commands BIS L-409 IO-Link Device Processor 10 Device Function Input buffer: Subaddress Bit-No. 00hex - 1st bit header BB HF AF 01hex Error code or data (LOWBYTE) 02hex Data 03hex Data 04hex Data or CRC_16 05hex Data (HIGHBYTE) or CRC_16 06hex not used 07hex - 2nd bit header BB HF AF CP CP Explanations for input buffer: Subaddress Bit name 00hex 1st bit header 01hex Meaning Function description BB Power 1 = Device is ready 0 = Device is in ground state HF Head Failure 1 = Head is turned off 0 = Head is turned on AF Job error 1 = Job incorrectly processed 0 = Job processed without error CP Codetag Present 1 = Data carrier is within range of the head 0 = No data carrier in range Error code Error number is entered if the job was incorrectly processed or canceled.

Reading is automatic and does not have to be initiated. The bit headers of the output buffer offer the possibility of having the device go into the ground state or to turn off a head. For this the corresponding control commands in the two bit headers need to be set (see “Process data” on page 42). If the bits are cleared again, the module resumes operation. The processor sends the current process data in each cycle. The data are only valid if the two bit headers agree. The bit headers show the status of the device and the subaddress 01hex … 05hex contains data. If an error occurs (AF bit =1), an error code is sent in subaddress 01hex (see “Process data” on page 42). If no data carrier is present (CP bit = 0), the stored data from the last data carrier are displayed until a new data carrier enters the active zone of the head. The stored data can be deleted with a reset by setting the GR bit. 10.5 Protocol examples The following examples show the protocol sequence in various situations.

BIS L-409 IO-Link Device Processor 10 Device Function 10.7 Data transmission timing Fig. 33: Timing of data carrier recognition and data transmission t1 t2 t3 Data carrier in range Data carrier recognized (Tag-Present LED, Codetag-Present bit) Data read time Polling time Cycle time In-Data: Input data Out-Data: Output data Process-Data-Cycle: Process data cycle Byte a+b: Process data x: Data required Data read time t1: Time until the data from a data carrier entering the read range are actually read. The read time is: 70 ms × number of parameterized data compare counts, Default = 2 (see “Map of parameterizing data” on page 33). Polling time t2: Time until it is recognized that the data carrier is no longer in the read range (polling time). The polling time is 50 ms. Cycle time t3: Time between the sending of two frames. The cycle time depends on the set baud rate and the respective Master (see “Direct Parameter Page” on page 30) In-Data/Out-Data: Sending of the input data and output data. 8 frames of 2 bytes each are sent, alternating process data and required data (x). Process Data Cycle: A process data cycle consists of the complete sending of the input and output data. At the beginning of each process data cycle the current data are polled and immediately sent. www.balluff.com 47 BIS L-409 IO-Link Device Processor 10 Device Function Updating the IOLink Master data When a data carrier enters the read range, its data are read and stored within time t1. The data are sent at the next start of a process data cycle (In-Data). The data carrier should be located within the read range at the start of a process data cycle so that the CP bit is set when the current data are polled. If the data carrier leaves the read range before polling, the data are sent but the CP bit is not set. If the dwell time of a data carrier in the read range is very short and if another data carrier immediately arrives, loss of data may result in the worst case. The minimum time until the most current data are available on the IO-Link Master is 16×t3. The time corresponds to the sending time of 16 frames or one process data cycle with the parameterized cycle time (depending on the set baud rate and the host Master, see also “Direct Parameter Page” on page 30). 48 BIS L-409 IO-Link Device Processor Appendix BIS L – 409 – 045 – 00X –07– S4 Ordering code Balluff Identification System Series L = Read system Hardware type 409 = Plastic housing, IO-Link Software type 045 = Software number, IO-Link Version 001 = Coil Ø 34 mm 002 = Offset read head M18 (0.5 m cable) 003 = Offset read head M12 (0.5 m cable) 004 = Remote read head C-305 housing (0.5 m cable) Interface 07 = IO-Link Module S4 = M12 4-pin male Accessories (optional, not included) www.balluff.com Accessories for the BIS L-409-... can be found in the Balluff IO-Link catalog.
