Safety Considerations
Series BIS C-60_2 processors along with the other BIS C system components comprise an
identification system and may only be used for this purpose in an industrial environment in
conformity with Class A of the EMC Law.
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 'Techni-
cal Data' for details.
Prevailing safety regulations must be adhered to when using the identification system. In par-
ticular, 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.
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.
This manual applies to processors in the series BIS C-6002-019-...-03-... and
BIS C-6022-019-050-03-....

Introduction
BIS C Identification Systems
Applications
☞
This manual is designed to assist the user in setting up the control program and installing and
starting up the components of the BIS C Identification System, and to assure rapid, trouble-
free operation.
The BIS C 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-program-
med Data carriers, but also for gathering and passing along up-to-date information as well.
If 2 read/write heads are connected to a BIS C-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 tool coding and monitoring;
– in equipment organization;
– in storage systems for monitoring inventory movement;
– in transporting and conveying systems;
– in waste management for quantity-based fee assessment.

Selecting System
Components
The BIS C-6002 processor has a plastic housing. Depending on the version, connections are
made either through a terminal strip, with the cable secured using a PG fitting, or via round
connectors. A single read/write head from BIS C-65_ series can be directly mounted to the
processor, which creates a compact unit. If the BIS C-650 adapter is attached instead of the
BIS C-65_ read/write head, two read/write heads may be cable connected. If the BIS C-670
adapter is attached, one read/write head may be cable connected.
The BIS C-6022 processor has a metal housing. Connection is made through round connec-
tors. Two read/write heads can be cable connected to the BIS C-6022 processor.
Series BIS C-60_2 processors have in addition a digital input. The input has various functions
depending on the configuration (see Parametering).
Whether the compact version of the processor with integrated read/write head makes sense
or whether the external solution is preferred depends primarily on the spatial arrangement of
the components. There are no functional limitations. All read/write heads are suitable for both
static and dynamic reading. Distance and relative velocity are based on which Data carrier is
selected. Additional information on the read/write heads in series BIS C-65_ and series
BIS C-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 repre-
sents an 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 C-60_2 Processor
Basic knowledge for application
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 re-
quired for recognizing whether the data were correctly read or written.
The processor is supplied with standard Balluff procedure of double reading and compar-
ing. 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 Advantages of double reading
Data checking even during the non-active phase
(CT outside read/write head zone).
No bytes on the data carrier need to be
reserved for storing a check code.
Shorter read times since each page is read only
once.
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 26).
It is not permitted to operate the system using both check procedures!

Communication between the BIS C-60_2 processor and the host system is via PROFIBUS-DP.
The PROFIBUS-DP system consists of the components:
– the bus master and
– the bus modules/slaves (here the BIS C-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 C are always identi-
cal!
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).

Station Address
For the correct parametering of the bus master as per type, a diskette, containing the unit’s
master data in the form of a GSD file is included with the BIS C-60_2 processor.
The Processor BIS C-60_2 is delivered with the station address 126. This has to be set indi-
vidually before using in a bus system. See information on 12.
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.
The possible settings are entered in the GSD file (and Type file). A minimum of 4 and a maxi-
mum of 128 bytes can be accommodated. However, it must be an even number.
Besides, in the case of the BIS C-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 para-
metering is described starting from 25.
The preset is stored in the GSD file.

Function Description
Communication with the processor
Communication between the host system and the processor takes place using a fixed proto-
col 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.

english
Input and Output
Buffers
In order to transmit commands and data between the BIS C-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 16 for example.
If a buffer size of less than 6 bytes (8 bytes with double bit header) 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 30) 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.

Function Description
Input and Output Buffers
☞
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: Subaddress 00 IB 32 and OB 32
(R/W 1) Input buffer IB 32 to IB 77
Output buffer OB 32 to OB 77
Read/Write Head 2: Subaddress 00 IB 78 and OB 78

Function Description
Parametering the BIS C-60_2 processor
Parameters,
Overview
There are 6 user parameter bytes stored on the Profibus master that can be used to activate
and deactivate various functions. 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 9).
– 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 →digital input low; IN = 1 →digital input high
– Reset BIS C-60_2 processor through the digital input:
If this function is activated, the processor is reset when the digital input is set to high.

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.

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 38ff):
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 bit 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 C-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.

Special
characteristics
Auto-Read
Function Description
Processing data carriers
Codetag Present As soon as the data carrier enters the active one of the read/write head, the processor indi-
cates 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.
To adjust the read/write functions to the numerous possible applications, a few unique fea-
tures have been implemented that the user can select and set when parametering or program-
ming the processor. These are as follows:
If the Auto-Read function is activated, the data are read as soon as a data carrier is recog-
nized. 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 deter-
mined 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 les if the buffer size has been set smaller).

Reading and writing
in dynamic mode
In normal operation a read/write job is rejected by the BIS C-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 without simultaneous data transmission: In the case of a read job the proces-
sor 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 29.
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 proces-
sor 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 29.
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.

Mixed Data Access
Function Description
Processing data carriers
Small read/write programs can be stored in the BIS C-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. non-contiguously 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 con-
tains 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 C-60_2 pro-
cessor. 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 num-
ber).
The individual program records must all be contiguous. They must be sent one after the other
and be terminated with 2 bytes 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.

Data Access
The command identifier 21Hex can be used to read out the program records stored in the pro-
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 11 on 51).
The command identifier 22Hex can be used to write the program records stored in the pro-
gram 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 12 on 52).
Copying from
Head 1 to Head 2
For a copy command there must be a data carrier in front of both read/write heads (even if
dynamic mode is configured). Simultaneous data transmission is used to read (even if si-
multaneous data transmission is not configured). The total process is controlled with the
bit header(s) for Head 1. The start address and number of bytes applies both to reading at
Head 1 and to writing at Head 2. The copy command is in principle the same as reading
with simultaneous data transmission. In addition, the data which are placed in the input
buffer are written at the same time to the data carrier at Head 2.
The AE bit is not set until the write procedure at Head 2 has finished successfully. If the
GR bit is set during a started copy command, both read/write heads are placed in the
base state and the pending job is aborted (see example 8 on 45).

To be able to use the CRC check, the data carrier must first be initialized with the com-
mand identifier 12Hex (see 36). 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 re-
placed.
If the CRC error is however due to a failed write request, you must reinitialize the data car-
rier 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 30 bytes or 62 bytes depending on data carrier type
(setup of page size see 17). This means that the actual usable number of bytes is re-
duced:
Data carrier type Usable bytes
128 bytes = 120 bytes
256 bytes = 240 bytes
511 bytes *) = 450 bytes
1023 bytes *) = 930 bytes
2047 bytes *) = 1922 bytes
2048 bytes = 1984 bytes

Initializing the Data carrier for the CRC_16 data checking
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 128 bytes shall be used
(BIS C-1_ _-03/L with 32 byte block size). Because 2 bytes are used for the CRC only
120 bytes can be used as data bytes, hence: start address = 0, number of bytes = 120.
