sis/status information. Device failure or breakdown of a read/write head can be detec-
ted and indicated by the master unit.
The protection of operating personnel and the system against possible
danger is not guaranteed if the control interface unit is not operated in
accordance with its intended use.
The devices IVI-KHD2-4HB6/IVI-KHA6-4HB6 may only be operated by
appropriately qualified personnel in accordance with this operating
manual.
Safety and correct functioning of the device cannot be guaranteed if any
operation other than that described in this operating manual is perfor-
med.
The connection of the equipment and any maintenance work to be car-
ried out with voltage applied to the equipment must only be performed
by appropriately qualified electro-technical personnel.
In the case that a failure cannot be repaired, the device must be taken
out of operation and protected against inadvertently being put back into
operation.
Repair work may only be carried out by the manufacturer. Additions or
modifications to the equipment are not allowed and void the warranty.
The responsibility for the observance to local safety standards lies with
the operator.

The control interface unit IVI-KHD2-4HB6/IVI-KHA6-4HB6 takes over the control of
the connected read/write heads that implement the data transmission with the code
or data carriers, prepares the read/write information and controls the communication
and data transmission with a PROFIBUS master unit.
It is possible to connect up to 4 read/write heads to a single IVI-KHD2-4HB6/IVI-
KHA6-4HB6 unit.
With the PROFIBUS, the complete read/write functionality is available. The control in-
terface unit operates as a passive subscriber of the system bus (slave).

If leads with double shielding are used, e.g. metallic wire mesh and
metallic foil, they must be connected to each other using a low impe-
dance connection at one end of the cable.
Many noise impulses come from the supply cables, e.g. switch-on cur-
rent of a motor. For this reason, running the supply cables in parallel
with the data/signal cables, especially in the same cable duct, should be
avoided.

5.4.2 Information for connecting the read/write head cable
The connecting cables to the read/write heads must be shielded. The cross section
of the cables must be at least 0.14 mm2.
The screen of the read head lead is connected on both sides to earth (PE) with low
resistence and low induction. For that the attached terminal block can be used (see
figure 5.5.). Please make sure that the screen is kept as small as possible.
Figure 5.5 Terminal block with connecting cables
Read head cable lengths up to 50 m or 100 m are possible if the following conditions
are satisfied:
up to 50 m read head cable: cross sectional area of at least 4 x 0.25 mm2
maximum resistance 78 Ohm/km
maximum capacitance 90 pF/m
(e.g. LIYC11C, Mukkenhaut & Nusselt MUNFLEX
C11Y)
up to 100 m read head
cable:
cross sectional area of at least 4 x 0.5 mm2
maximum resistance 37 Ohm/km
maximum capacitance 90 pF/m
With a cable length of 100 m, a series resistor of 82 Ohm must be fitted
in the cable connected to the 'Reset' terminal of the read heads.
Since more EM interference can result with longer cable lengths, the
maximum cable lengths given above might not be possible for some
applications.

5.4.3 Special connection information for the PROFIBUS cable
The connecting lead for the bus is specified in the EN 50170 as type A cable and can
be used in accordance with the following table. Line parameters and lengths for a type
B cable are also included in the following tables for the sake of completeness. Only
cable of type A should be used in new designs because of the longer overall length
of leads in systems.
Line parameters as follows:
Line B*) not to be used in future, if possible.
Transmission rates
The following transmission rates are supported:
9.6 kbit/s, 19.2 kbit/s, 44.44 kbit/s, 93.75 kbit/s, 187.5 kbit/s, 500 kbit/s and 1.5 Mbit/s.
The setting of the transmission rate required is self-synchronising.
If leads with double shielding are used, e.g. metallic wire mesh and
metallic foil, they must be connected to each other using a low impe-
dance connection at one end of the cable.
Many noise impulses come from the supply cables, e.g. switch-on cur-
rent of a motor. For this reason, running the supply cables in parallel
with the data/signal cables, especially in the same cable duct, should be
avoided.

Length of leads
The reliable lengths of the transmission leads in a bus segment are determined from
the following:
•type of bus cables used
•influence of external noise
•transmission rate
•number of bus subscribers
The maximum total lead length of a bus segment as a function of the transmission rate
for maximum number of subscribers (32) is:
Bus termination
With the PROFIBUS, every bus segment must be terminated via terminating resis-
tances at both ends of the bus leads.
Figure 5.6 Rotating switch S9 for the termination of the bus
The control interface unit IVI-KHD2-4HB6/IVI-KHA6-4HB6 has built-in, switchable
bus termination. The bus termination can be activated by turning the rotating switch
S9 on the left hand side of the unit housing with an appropriate screwdriver.

By breaking into multiple bus segments and the application of repea-
ters, the transmission length can be increased. A maximum of three
repeaters between two communicating bus subscribers can be used.
If leads with double shielding are used, e.g. metallic wire mesh and
metallic foil, they must be connected to each other using a low impe-
dance connection at one end of the cable.
Many noise impulses come from the supply cables, e.g. switch-on cur-
rent of a motor. For this reason, running the supply cables in parallel
with the data/signal cables, especially in the same cable duct, should be
avoided.

6 Commissioning
6.1 Preparation
Due to the complexity of field bus programming with the PROFIBUS, it is, unfortuna-
tely, difficult to give a valid general description on how to perform the commissioning.
A very important aspect for the operation of an inductive identification system using
the control interface unit IVI-KHD2-4HB6/IVI-KHA6-4HB6 on the PROFIBUS is the re-
sponse time of the total system. The question "How much time is required for data to
be available in my computer once the code carrier is positioned in front of the read
head?" cannot be correctly answered in general.
The important factors in respect to response time are:
•type of high order host system, e.g. PLC or PC
•type of PROFIBUS master, e.g. pre-defined transmission rate
•communication between the PROFIBUS master and the host system
•the number of PROFIBUS subscribers
•the number of control interface units on the PROFIBUS
•the number and type of read/write heads connected
•type of code or data carriers used
•type of access of the communications objects of the control interface unit
•type of commands on the identification system
•structure of the user program
For this reason, you should construct a test system for your particular application and
check the transmission to the PROFIBUS master or host system if you have little ex-
perience with the design of a PROFIBUS system.
Before proceeding with the commissioning, make sure that no danger
to the system can arise from the device, e.g. due to uncontrolled control
processes.
Check again all connections before proceeding with the commissioning.
Prepare for the commissioning by familiarising yourself with the com-
munication between the PROFIBUS master and the control interface
unit (see chap. 7). The commissioning requires a good knowledge of
the PROFIBUS and the programming of the master unit.

6.2 Main procedure
Before the commissioning, the system address of the control interface unit and, if ne-
cessary, of the bus termination (chapter 5.4.3 "Special connection information for the
PROFIBUS cable") must be set.
Setting of the unit address
Select a device address not already occupied by another bus subscriber (between 0
and 126) and set this address using the DIP switch on the front of the device.
Figure 6.1 Setting the device address
A complete series of design tools exist that allow a PROFIBUS user to
plan and commission a network, even if he/she has no knowledge of
the fundamental communication sequences.
There are PC programs and PROFIBUS PC connector cards which
help determine the communication relationships and your parameters,
and can clearly display bus telegrams on the screen.
The system software of programmable logic controllers (PLC) with a
PROFIBUS communication processor often offer network configuration
and management possibilities.

After connecting to voltage, the control interface unit automatically adjusts its trans-
mission rate to that of the master. The supported rates are:
Configuration of the network master(s) for DP operation
The configuration data required for the control interface unit IVI-KHD2-4HB6/IVI-
KHA6-4HB6 can be found in the GSD file supplied and the network master is confi-
gured accordingly. If you have a configuration tool, then the network master is confi-
gured automatically by using the configuration tool to read the GSD file.
The device address must be entered to do this.
Self test
After switching on the supply voltage, the control interface unit checks the internal me-
mory area with a self test. If a device error or transmission error occurs, or if an incor-
rect device address is set, communication will not be activated. The error is indicated
with the LED "Run/Error" (see chap. 8 "Fault Diagnostics").
Interconnection structure
The interconnection structure is established automatically in DP mode
It is now possible to communicate with the control interface unit IVI-KHD2-4HB6/IVI-
KHA6-4HB6 using the PROFIBUS master.

7.2.4 Definition of PROFIBUS DP modules
For the transmission of the entry data (read, data from slave to DP-master) and output
data (write, data from DP-master to slave) are an input and output module defined.
The size of the input module and output module is variable. At this way, the quantity
(from Firmware-Version 1801K017 from the 22nd June 1998) of the data is optimized
for the actual application. This avoided an unnecessary load of the bus through not-
used data.
For using the variable length of the module, you need the master data file P&F_0840.GSD
Revision 1.2 from the 10th July 1998. In this file, the input module with a word length from
2 to 16 and the output module with a word length up to 16 are predefined.
The size of the module you need is dependent from the application. The output mo-
dule (data from DP-master to slave) contains one or two commands and up to 14
words data.
The input module (data from slave to DP-master) always contains two words status
and up to 14 words data.
Examples:
Command "Single/Auto/Buffered Read Fixcode"
Only one word commands and command parameters are transmitted. A data carrier
word address or write data are not used. Here you can still use the "1 Word Output"
module.
The length of the fixcode-data which reads the code carrier amounts to 4 words. Be-
cause always two words status are additional transmitted, the minimum size of the in-
put module must be 6 words. You must choose the "6 Words Input" module.
Command "Single/Auto/Buffered Write", write data-length 14 words
Here are two words for the commands (command, parameter and data carrier
word address) required. Together with the 14 words write data the maximum output
module length results in 16 words (16 words output).
For valid read commands, the control interface unit responds only with the status
command, so the input module size of two words is enough (2 Words Input).
Command "Single/Auto/Buffered Read", read data-length 8 words
For the transmission of the read commands are two words necessary (commands,
command parameters and data carrier word address), so module "2 Words Output"
is enough.
For the transmission of the read commands and the two words status commands are
totally 10 words necessary, so modul "10 Words Input" is fit.
The structure of the 16 data words for the communication direction from DP master
to control interface unit and from control interface unit to DP master is described in
the following two chapters.
At projecting, select only one input module and one output module from
the table.

7.2.5 Communication direction: PROFIBUS DP Þ control interface unit
The transmitted data are depending from the length of the chosen output mode.
In the following, only the structure of the necessary words are shown. If, depending
from the module size, further words are generated, these words contain no valid data.
Reading Fixcode
Commands and command parameters are transmitted in word 0.
Reading data
Commands and command parameters are transmitted in word 0. Word 1 contains the
starting memory address for the data carrier, as of which the data are read or written.
Writing data
Depending from the chosen modul size is n maximum 16.
Commands and command parameters are transmitted in word 0. Word 1 contains the
starting memory address for the data carrier, as of which the data are read or written.
The words 2 ... 15 include the data to be written for write commands. For read com-
mands, the words 2 ... 15 do not contain valid data.

Toggle flag (T)
The toggle flag serves to unambiguously identify a new command which is valid. A
new command is only then accepted by the control interface unit and executed provi-
ded this flag does not have the same status as the preceding command, i.e. when it
is toggled.
In the acknowledgment from the control interface unit to the DP master, the toggle flag
does not change and serves to indicate to the user that the command was received
by the control interface and has been processed.
Command identification (B4 ... B1)
The desired command is defined by the command parameters B4 ... B1.
A detailed description of these commands is given in chapter 4.3 "System descripti-
on".
Execution of the command is finished, when the execution counter
became ¹ 0.

7.2.7 PROFIBUS DP command sequence, example
The execution of the command commences as soon as a valid command has been
written in the register with a toggled flag "T". After reception of the command, this flag,
together with the remaining fields of the word 0, are passed back to the master as ack-
nowledgement.
The execution counter is incremented on each command from the IDENT system. All
the same time, the fields head number, status, read error flag, read numbers and fix-
code data are set in accordance with the IDENT system message. The handling of
the read error flag also depends on the command.
The read numbers are incremented when read data has been received from the
IDENT system (Status 0). Only the read number of the data field is incremented, that
is assigned to the head number sent by the IDENT system. The read number is not
incremented if the IDENT system reports an error (Status 4, 5, 6).
The read error flag is not operated for the commands SF, AF und BF and always re-
mains at 0.
The following applies to the command EF: The read error flag is reset (=0) as soon as
read data has been received from the IDENT system (Status 0). The read error flag
is set as soon as the IDENT system reports a read error (Status 5), and remains un-
changed for other error messages (Status 4, 6).
A command sequence is shown in the following example.
Command: "Single Read Fixcode" with Head 2, without doubleside mode
Command from the DP master
Anfangszustand:
Head number (K3...1) 0
Execution counter (N4...1) 0

10.2 Example of commissioning
In this chapter is shown a commissionig of an SPS SIMATIC S5 135 with an IM308C
assembly module.
10.2.1 Brief description
The Pepperl+Fuchs IVI-KH❏❏-4HB6 interface unit (bus address 3) is connected to
the S5 via the IM308C PROFIBUS master (bus address 1). The interface is used to
exchange 16 words input data and 16 words output data via the PROFIBUS. Parame-
ter assignment of the IM308C is carried out with the COM PROFIBUS program.
The 16 words input data and 16 words output data are read from the interface unit into
the DB830 data module, using the FB192 function module and written to the interface
unit from the DB31 data module.

10.2.3 Parameter assignment of the IM308C with COM PROFIBUS
After starting the COM PROFIBUS program, the GSD file provided with it must now
be read-in via the menu item 'File', unless this has already been carried out. The pro-
gram interface unit is referenced under ‘other’ devices. Parameter assignment of the
IM308C can now be started for a new project. The individual steps required are sum-
marised briefly in the following. To start a new project, select 'File -> New’ from the
menu.
First the PROFIBUS master is defined. In the example, the IM308C card is used as
the master, with bus address 1 and an S5-135U with a CPU928B is used as the S5
station. The appropriate selection is accepted by pressing the OK button.

By double-clicking on master system a window is opened, on the right side of which
a PROFIBUS slave selection table appears. The interface unit can now be inserted
as 'another' slave. In the example, address 3 is set as the bus address.
As before, the settings are accepted by pressing the OK button.

On successful selection, the DP-Master system window appears in which the PRO-
FIBUS string is represented.
If the previous settings have been made correctly, the identification of the interface
unit appears in the rectangle with bus address 3.
Data transfer with the interface unit can now be configured by double-clicking on this
rectangle.

On selecting the Order Number button, a window opens in which the fixed input/out-
put data are presented. This information relates to the COM PROFIBUS program
from the GSD file.
A 16 words input (see Figure 10.4) and a 16 words output (see Figure 10.5) have to
be selected for the configuration and accepted by actuating the appropriate button.
The window can then be closed.

Figure 10.5
The numbers 223 and 239 should now be entered under the term 'Code'. These two
numbers represent the transfer parameters shown in figure 10.6 and figure 10.7.
16 words of input data are transferred from the interface unit and 16 words of output
data are transferred to the interface unit via the PROFIBUS. This transfer must take
place consistent with the assembly module. As a consequence of this, the data can-
not be accessed directly via the input/output address range. The function module
FB192 must be used for the transfer, in conjunction with data modules for acceptance
of the data.
The FB192 provides data communication between the S5CPU and the IM308C.

10.2.5 Examples
Commands can be sent to the interface unit by changing the data word DW0 of the
DB31.
Continuous read-in of a fixcode with read head No. 3 (Buffered-Auto-Read Fix-
code)
Output data:
DB31 DW 0 PROFIBUS master command to the interface uni
t
DB31 DW 1 ... 15 are not considered.
Input data:
DB30 DW 0 Mirror imaging of the command from the interface unit to the PROFIBUS
master
DB30 DW 1 Status/execution counter/head number
K3 ... 1: Read head number
N4 ... 1: 4 bit execution counter
S4 ... 1: Status/error message
DB30 DW 2 ... DW5: Read data
When sending commands, care should be taken that bit 0 of the data
word DW0 is always toggled, in order to give the card validity.
T = 0, if previously 1
T = 1, if previously 0
For the 1st command the toggle bit (T) must be 1.
