Installation and Operation Installation and operation should be carried out by trained personnel only. Unauthorized work and improper use will void the warranty and liability. When installing the processor, follow the chapters containing the wiring diagrams closely. Special care is required when connecting the processor to external controllers, in particular with respect to selection and polarity of the signals and power supply. Only approved power supplies may be used for powering the processor. See chapter 'Technical Data' for details. Use and Checking Prevailing safety regulations must be adhered to when using the identification system. In particular, steps must be taken to ensure that a failure of or defect in the identification system does not result in hazards to persons or equipment. This includes maintaining the specified ambient conditions and regular testing for functionality of the identification system including all its associated components. Fault Conditions Should there ever be indications that the identification system is not working properly, it should be taken out of commission and secured from unauthorized use. Scope This manual applies to processors in the series BIS S-6002-019-050-03-ST11 and BIS S-6022-019-050-03-ST14. S60_2-019_828318_0303-e mit CRC.p65 Introduction BIS S Identification Systems This manual is designed to assist the user in setting up the control program and installing and starting up the components of the BIS S Identification System, and to assure rapid, troublefree operation. Principles The BIS S Identification Systems belongs in the category of non-contact systems for reading and writing. This dual function permits applications for not only transporting information in fixed-programmed Data carriers, but also for gathering and passing along up-to-date information as well. ☞ Applications If 2 read/write heads are connected to a BIS S-60_2 processor, both heads can be operated independently of each other. This means for example that you can read a Data carrier from one head while writing to another Data carrier at the other head. Some of the notable areas of application include – for controlling material flow in production processes (e.g. in model-specific processes), for workpiece conveying in transfer lines, in data gathering for quality assurance, for gathering safety-related data, – in equipment organization; – in storage systems for monitoring inventory movement; – in transporting and conveying systems; – in waste management for quantity-based fee assessment. Introduction BIS S Identification Systems System Components The main components of the BIS S Identification Systems are: – Processor, – Read/Write Heads and – Data carriers Configuration with BIS S-6002 and BIS S-6022 processor PROFIBUS-DP Processor BIS S-6002 BIS S-3_ _ Schematic representation of an Identification System (example) Processor BIS S-3_ _ Read/write head BIS S-6022 BIS S-3_ _ Data carriers BIS S-1_ _-... BIS S-3_ _ S60_2-019_828318_0303-e mit CRC.p65 BIS S-60_2 Processor Basic knowledge for application Selecting System Components The BIS S-6002 processor has a plastic housing. The BIS S-6022 processor has a metal housing. Connection is made through round connectors. Two read/write heads can be cable connected. Series BIS S-60_2 processors have in addition a digital input. The input has various functions depending on the configuration (see Parametering). The read/write distances depend on which data carriers are used. Additional information on the read/write heads in series BIS S-3_ _ including all the possible data carrier/read-write head combinations can be found in the manuals for the respective read/write heads. The system components are electrically supplied by the processor. The data carrier represents a free-standing unit and needs no line-carried power. It receives its energy from the read/write head. The latter constantly sends out a carrier signal which supplies the code head as soon as the required distance between the two is reached. The read/write operation takes place during this phase. Reading and writing may be dynamic or static. BIS S-60_2 Processor Basic knowledge for application Control Function The processor writes data from the host system to the Data carrier or reads data from the tag through the read/write head and prepares it for the host system. Host systems may include: – a host computer (e.g. industrial PC) or – a programmable logic controller (PLC) When sending data between the read/write head and the Data carrier a procedure is required for recognizing whether the data were correctly read or written. Data checking The processor is supplied with standard Balluff procedure of double reading and comparing. In addition to this procedure a second alternative is available: CRC_16 data checking. Here a test code is written to the Data carrier, allowing data to be checked for validity at any time or location. Advantages of CRC_16 Data checking even during the non-active phase (CT outside read/write head zone). Shorter read times since each page is read only once. Advantages of double reading No bytes on the data carrier need to be reserved for storing a check code. Shorter write times since no CRC needs to be written. Since both variations have their advantages depending on the application, the user is free to select which method of data checking he wishes to use (see Parametering on 23). ☞ It is not permitted to operate the system using both check procedures! S60_2-019_828318_0303-e mit CRC.p65 BUS interface PROFIBUS-DP Communication between the BIS S-60_2 processor and the host system is via PROFIBUS-DP. PROFIBUS-DP The PROFIBUS-DP system consists of the components: – the bus master and – the bus modules/slaves (here the BIS S-60_2 processor). ☞ Important hints for use with PLC: In some control systems the PROFIBUS-DP data area is not synchronously transmitted with the updating of the input/output content. If more than 2 bytes of data are sent, a mechanism must be used which guarantees that the data in the PLC and the data in the BIS S are always identical! 1st alternative: Synchronous data transmission as a setting on the Master In this method the bus Master ensures that all the data necessary for the respective Slave are always sent contiguously. There is usually a special software function in the PLC which likewise controls access between the PLC and bus Master so that data are always sent contiguously. 2nd alternative: Set 2nd bit header Data exchange between PLC and BIS is controlled by the so-called bit header. This is always the first byte of the respective read/write head in the data buffer. This bit header exists both in the input range (data from BIS to the PLC) and in the output range (data from the PLC to the BIS). lIf this bit header is also sent as the last byte, a comparison of these two bytes can be used to guarantee the consistency of the transmitted data. In this method the PLC cycle is unaffected nor is the bus access time changed. All that is required is that a byte in the data buffer be used for the 2nd bit header instead of for user data. This 2nd alternative is the Balluff recommended setting (factory default). 10 BUS interface PROFIBUS-DP Unit's Master Data For the correct parametering of the bus master as per type, CD ROM, containing the unit’s master data in the form of a GSD file is included with the BIS S-60_2 processor. Station Address The Processor BIS S-60_2 is delivered with the station address 126. This has to be set individually before using in a bus system. See information on 11. Input/Output Buffer An input buffer and an output buffer are used for the data exchange with the control system. The size of these buffers has to be configured via the master. ☞ Parametering Bytes User-Parameter Bytes ☞ 10 The possible settings are entered in the GSD file (and Type file). A minimum of 4 and a maximum of 128 bytes can be accommodated. However, it must be an even number. Besides, in the case of the BIS S-60_2 processor, there are 6 further bytes (User-Parameter Bytes) which have to be set while parametering. The significance of the 6 bytes for parametering is described starting from 22. The preset is stored in the GSD file. S60_2-019_828318_0303-e mit CRC.p65 11 BUS interface PROFIBUS-DP Station Address setting The station address under which the unit is accessed on the bus can be assigned through the slide switch S1. Each address shall be assigned only once. The slide switch S1 is binary coded. The setting of the station address is carried out according to the scheme shown in the table. Switch position: no = left, yes = right. The address 85 is set in the following figure. Head2 Head1 S1 on on on on on on on on ➪ Station Address Head 2 Slide switch S1 26 25 24 Head 1 no yes 23 22 21 20 yes not allowed no no no no no no no no no no no yes no no no no no no yes yes no no no no yes no no no no no no yes no yes yes no yes no yes no yes 123 yes yes yes yes no yes yes 124 yes yes yes yes yes no no 125 yes yes yes yes yes no yes 126 yes yes yes yes yes yes no ... 85 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 ... on on on S2 always on no Slide switch S1 (with cover removed) 127 X1 X2 not allowed X3 To open the cover of the processor, see 52 for BIS S-6002 or 62 for BIS S-6022. 11 12 Function Description Communication with the processor Basic Procedure Communication between the host system and the processor takes place using a fixed protocol sequence. Data integrity from the control to the processor and vice-versa is indicated by a control bit. This bit is used to implement a handshake between the control and the processor. Following is a simplified representation of the sequence of a job sent from the control to the processor: 1. The control sends a command designator to the processor together with the associated command parameters and sets a bit (AV bit). This bit indicates to the processor that the transmitted data are valid and that the job is now beginning. 2. The processor takes the job and sets a bit (AA bit), which indicates this to the control. 3. If an additional exchange of data between the control and the processor is required to carry out the job, each uses a bit (TI bit and TO bit) to indicate that the control / processor is now ready for additional data exchange or has accepted the received data. 4. Once the processor has carried out the job correctly, it sets a bit (AE bit). 5. Once the control has accepted all the important data, it indicates this to the processor by resetting the bit that was set at the beginning (AV bit). 6. The processor now in turn sets all the control bits that were set during the sequence (AA bit, AE bit) and is ready for the next job. Please see also 25...31 and the examples on 32...47. 12 S60_2-019_828318_0303-e mit CRC.p65 13 Function Description Input and Output Buffers Input and Output Buffers In order to transmit commands and data between the BIS S-60_2 and the host system, the latter must prepare two fields. These two fields are: – the output buffer for the control commands which are sent to the BIS Identification System and for the data to be written. – the input buffer for the data to be read and for the designators and error codes which come from the BIS Identification System. The possible setting values are stored in the GSD file. The buffer size can be selected between 4 and 128 bytes in steps of 2 bytes. This must be given by the master during parametering. The total buffer size is divided into 2 ranges: Buffer range 1 for Read/Write Head 1; size is specified in paramter byte 6. Buffer range 2 for Read/Write Head 2; size = total buffer size – buffer size of Read/Write Head 1. See 14 for example. ☞ Please note the basic procedure on 12 and 25...31 and the examples 32...47. on pages If a buffer size of less than 8 bytes is set for a read/write head, a read/write request can be carried out without specifying the start address and the number of bytes. Automatic reading for Codetag present (see 26) remains active. This permits fast reading of small data quantities without placing an unnecessary load on the bus. Buffer size – 1 = number of bytes read without double bit header; Buffer size – 2 = number of bytes read with double bit header. 14 Function Description Input and Output Buffers Input and Output Buffers (continued) Example: The 82 bytes for the total buffer need to be distributed. An input/output buffer of 46 bytes is assigned to Read/Write Head 1. This results in an input/output buffer of 36 bytes for Read/Write Head 2. Procedure: The buffer size for Read/Write Head 1 is set to 46 bytes. This means using the parameter byte 6 to enter Hex value 2E (corresponds to 46 decimal), which corresponds to binary 00101110. PLC Organisation: The buffer range starts at input byte IB 32 and output byte OB 32. Result: Read/Write Head 1: (R/W 1) Read/Write Head 2: (R/W 2) ☞ Subaddress 00 Input buffer Output buffer IB 32 and OB 32 IB 32 to IB 77 OB 32 to OB 77 Subaddress 00 Input buffer Output buffer IB 78 and OB 78 IB 78 to IB 113 OB 78 to OB 113 Note that these buffers can be in two different sequences depending on the type of control.

Setting is done directly by linking a device to the Profibus master. The parameter default settings are stored in the GSD file. – CRC_16 data check: If this function is activated, the correctness of the read or written data is ensured by a CRC_16 data check (see 8). – Simultaneous data transmission for both read/write heads: With simultaneous data transmission shorter read/write times can be achieved depending on the amount of data to be read/written and the type of controller. – Dynamic operation on read/write head 1 or 2: If dynamic operation is parametered, a read/write job can be sent even though there is no Data carrier in the active zone of the head. As soon as a Data carrier passes by the head, the command is immediately carried out. – "Auto-Read” for read/write head 1 or 2: If this function is activated, the processor reads out the first (max. 31) bytes from the Data carrier starting at a defined start address as soon as the tag enters the active zone of the read/write head. The start address must first have been stored in the processor’s EEPROM with the command ID 07Hex. – 2nd bit header at end of in- and output buffer: The 2nd bit header (factory setting) prevents data from being accepted by the bus as long as it is not fully updated. – Display state of the digital input in the bit header of the input buffer: If this function is activated, the IN-bit displays the state of the digital input of the processor: IN = 0 Õ digital input low; IN = 1 Õ digital input high – Reset BIS S-60_2 processor through the digital input: If this function is activated, the processor is reset when the digital input is set to high.

Reset. 48/49) The specification for the input and output buffer on the Master applies to both read/write heads, i.e. this buffer must be divided for both heads. The specification is done in Hex format and must be in a range between 02Hex and 80Hex (128 dec.). ☞ If only one read/write head (Head 1) will be used, you may enter the same value here as for the total buffer size. An entry of less than 2 bytes results in an undefined state. Please note the basic procedure on 24 12 and 25...31 and the examples on pages 32...47. S60_2-019_828318_0303-e mit CRC.p65 25 Function Description Processing data carriers Reading and writing To carry out a read or write job, the Data carrier must be located in the active zone of the read/ write head. A read/write job has the following sequence (see examples on 32ff): 1. The host sends to the output buffer: – the command designator to subaddress 01Hex, – the start address for reading or writing to subaddress 02HEX/03HEX, – the number of bytes for reading or writing to subaddress 04HEX/05HEX, – the CT bit in the bit header according to the Data carrier type (block size), – and sets the AV bit in the bit header to high. 2. The processor: – takes the request (AA in the bit header of the input buffer to high), – begins to transport the data; read = from data carrier to input buffer, write = from output buffer to data carrier. (Larger data quantities are sent in blocks block size with 2nd bit header = buffer size – 2), block size without 2nd bit header = buffer size – 1). The toggle bits in the two bit headers are used as a kind of handshaking between the host and the BIS S-60_2 processor. 3. The processor has processed the command correctly (AE bit in the bit header of the input buffer). If an error occurred during execution of the command, an error number will be written to subaddress 01Hex of the input buffer and the AF bit in the bit header of the input buffer will be set. 25 26 Function Description Processing data carriers Codetag Present ☞ As soon as the data carrier enters the active one of the read/write head, the processor indicates this by setting the CP bit (Codetag Present). To accelerate the reading of small amounts of data, the ID system makes the first bytes of the data carrier available in the input buffer of the respective read/write head as soon as the tag is detected (30 bytes with 2nd bit header, 31 bites without 2nd bit header, or less if the buffer size has been set smaller). The data are only valid after the rising edge of the CP bit in the bit header of the input buffer. They remain valid until the falling edge of the CP bit, or until the controller issues a new job. Special characteristics To adjust the read/write functions to the numerous possible applications, a few unique features have been implemented that the user can select and set when parametering or programming the processor. These are as follows: Auto-Read If the Auto-Read function is activated, the data are read as soon as a data carrier is recognized. No command from the controller is required. Since there is an in- and output buffer for each read/write head, the start address must be specified for each head using the command designator 07Hex. The start addresses may be different. The number of bytes read is determined by the selected size of the input buffer, which is distributed over both heads when 2 are used. This distinguishes the Auto-Read function from the standard setting for automatic reading, which always starts at Address 0 and includes a maximum number of 30 bytes with 2nd bit header or 31 bytes without 2nd bit header (or less if the buffer size has been set smaller). 26 S60_2-019_828318_0303-e mit CRC.p65 27 Function Description Processing data carriers Reading and writing in dynamic mode In normal operation a read/write job is rejected by the BIS S-60_2 processor by setting the AF bit and an error number if there is no data carrier in the active zone of the read/write head. If dynamic mode is configured, the processor accepts the read/write job and stores it. When a data carrier is recognized, the stored job is carried out. Reading and writing with simultaneous data transmission Reading without simultaneous data transmission: In the case of a read job the processor first reads our all requested data from the data carrier after receiving the start address and the desired number of bytes, and then sets the AE bit. Then the data read from the data carrier are written to the input buffer. In the case of larger data amounts this is done in blocks, controlled by the handshake with the toggle bits as described on 25. Reading with simultaneous data transmission: In the case of a read job the processor begins by transmitting the data into the input buffer as soon as the first 30 bytes (with 2nd bit header, or 31 bytes without 2nd bit header, or less if the buffer size was set smaller) have been read from the data carrier beginning with the start address, and indicates this by inverting the TO bit. As soon as the controller inverts the TI bit, the processor sends the data, which have in the meantime been read, to the input buffer. This is repeated until the processor has read out all the desired data from the data carrier. Now the processor sets the AE bit and outputs the remaining data on the input buffer. Writing without simultaneous data transmission: In the case of a write job the processor waits until it has received all the data that need to be written from the controller. Only then are the data written to the data carrier as described on 25. Writing with simultaneous data transmission: In the case of a write job the processor begins to write the data to the data carrier as soon as it has received the first data to be written from the controller’s output buffer. Once all the data have been written to the data carrier, the AE bit is set. 27 28 Function Description Processing data carriers Mixed Data Access Small read/write programs can be stored in the BIS S-60_2 processor’s EEPROM. The Mixed Data Access function is useful when the required information is stored on the data carrier at various addresses. This function makes it possible to read out this “mixed”, i.e. noncontiguously stored data from the data carrier in a single procedure and using just one command. Up to 10 programs with up to 25 instructions can be stored. Each program instruction contains a “start address” and a “number of bytes” specification. The amount of data for reading may not exceed 2 kB. Storing a program: The command identifier 06Hex is used to send the read/write program to the BIS S-60_2 processor. One program per command can be stored. All 25 program records plus an additional 2 bytes with FFHexFFHex as a terminator must always be sent. This means a total of 104 bytes of information per program must be sent (including the command identifier and program number). ☞ The individual program records must all be contiguous. They must be sent one after the other and be terminated with FFHexFFHex as a terminator. It is recommended that the remaining, unused memory sector be filled with FFHexFFHex. If an address range is selected twice, the data will also be output twice. 28 S60_2-019_828318_0303-e mit CRC.p65 29 Function Description Processing data carriers Mixed Data Access (cont.)

The procedure for writing these settings to the EEPROM is described in the 9th example on 42...44. Replacing the EEPROM is described on 56 for BIS S-6002 and on 66 for BIS S-6022. 29 30 Function Description Processing data carriers The command identifier 21Hex can be used to read out the program records stored in the proRead from data carrier, with program gram from the data carrier. The user must document exactly which data are to be read from where and with what number of bytes for the respective program (see example 10 on 45) Mixed Data Access Write to data carrier, with program Mixed Data Access 30 The command identifier 22Hex can be used to write the program records stored in the program to the data carrier. The user must document exactly which data are to be written from where and with what number of bytes for the respective program (see example 11 on 46) S60_2-019_828318_0303-e mit CRC.p65 31 Function Description Processing data carriers CRC initialization To be able to use the CRC check, the data carrier must first be initialized with the command identifier 12Hex (see 32/33). The CRC initialization is used like a normal write job. The latter is rejected (with an error message) if the processor recognizes that the data carrier does not contain the correct CRC. Data carriers as shipped from the factory (all data are 0) can immediately be programmed with a CRC check. If CRC-16 data checking is activated, a special error message is output to the interface whenever a CRC error is detected. If the error message is not caused by a failed write request, it may be assumed that one or more memory cells on the data carrier is defective. That data carrier must then be replaced. If the CRC error is however due to a failed write request, you must reinitialize the data carrier in order to continue using it. The checksum is written to the data carrier as a 2-byte wide datum. Two bytes per page are 'lost', i.e., the page size becomes 62 bytes. This means that the actual usable number of bytes is reduced: Data carrier type 8192 bytes 16384 bytes Usable bytes 7936 bytes 15872 bytes 32 Function Description Examples for protocol sequence Example No. 1 Initializing the Data carrier for the CRC_16 data checking For configuring with double bit header and 128-byte buffer size! The processing of this command is similar to a write command. Start address and number of bytes have to correspond to the maximum number of data to be used. In this example the complete memory range of a Data carrier with 8 kbytes shall be used (BIS S-1_ _-32/L with 64 byte block size). Because 2 bytes are used for the CRC only 7936 bytes can be used as data bytes, hence: start address = 0, number of bytes = 7936. Host: BIS S-60_2 Identification System: 1.)
