Figure 1-1 Communications modules for FB 45
The section "Brief description of the hardware" in the Appendix illustrates configurations with
the various communications modules. FB 45 can be operated in various different
configurations:
● The CM is operated directly in a SIMATIC S7-300.
● The communications module is located in the rack of an ET 200M or ET 200pro. The
ET 200M/ET 200pro is used with an S7-300 or S7-400.
● The CM is a self-contained PROFIBUS slave and is connected to the integrated
PROFIBUS connector of a SIMATIC S7-300 or S7-400.
● The CM can be operated both via PROFIBUS or PROFINET.
● The CM is operated on PROFINET via the IE/PB Link.
These configurations can be mixed and different communications modules can also be
connected.
Assign parameters for the RF600 reader with FB 45
A separate manual is available for the parameter assignment of the RF620R/RF630R
readers. In the "Configuration Manual RF620R/RF630R
(http://support.automation.siemens.com/WW/view/en/33287195)" manual, you will find all the
important information about commissioning, parameter assignment, error messages and
how to handle errors/faults as well as many examples and applications for using the RF600.

Compatibility note
FB 45 is the successor to FC 45. FB 45 is almost completely compatible with FC 45. Users
can run FC 45 application programs with FB 45 without modification. Unlike FC 45, a
separate instance DB has to be assigned for each FB 45 call. UDT 10 has been shortened
from 300 bytes to 50 bytes as a result. The application-related variables of UDT 10 are the
same.
Features of the interface
The features of the individual CMs are described in the section "Brief description of the
hardware (Page 81)".
Since the features of the individual CMs are continuously being expanded, you should
always use the latest edition of this description.
Performance features of FB 45
● All identification systems (RFID and code reading systems) can be operated with FB 45.
● The user can process a complete transponder with one command (up to 64KB).
● The user can chain several commands together. This means that many small data areas
of a transponder can be processed with one command start.
● The data structures are set up conveniently via user-defined data types (UDTs). The
UDTs are available with English (UDT 10, 20), German (UDT 11, 21) and Spanish (UDT
14, 24) commentary. In this description, the UDTs are always referred to by their English
designation (UDT 10, 20).
● Data is transmitted to and from the CM and commands are executed on the CM at the
same time. This means optimal data throughput.
● The use of symbolic names enhances the clarity in the user program, even where
complex configurations are involved.
Position in the information landscape
This function manual describes the use of FB 45 for the RFID systems MOBY D, MOBY U,
RF200 and RF300. MV400 code readers can also be used with FB 45.
Please note that a separate manual is available for parameter assignment of the
RF620R/RF630R reader with function block FB 45. In the "Configuration Manual
RF620R/RF630R (http://support.automation.siemens.com/WW/view/en/33287195)" manual,
you will find all the important information about commissioning, parameter assignment, error
messages and how to handle errors/faults as well as many examples and applications for
using the RF600.
You will find the documentation on parameter assignment of the code reading systems in:
"Parameter assignment of the code reading systems
(http://support.automation.siemens.com/WW/view/en/38845041)"

Function Manual, 07/2012, J31069-D0166-U001-A4-7618 7
PROFIBUS configuration
A GSD file is available on the "RFID Systems Software & Documentation" DVD
(6GT2080-2AA20) for the communications modules that can be connected directly to
PROFIBUS.
PROFINET configuration
A GSDML file is available on the "RFID Systems Software & Documentation" DVD
(6GT2080-2AA20) for the communications modules that can be connected directly to
PROFINET.
Non-SIMATIC applications
Applications programmed on third-party controllers cannot use FB 45.
When programming the third-party controller, keep to the standard IEC 61131:
● The third-party controller can be programmed according to IEC 61131:
Use the function block RFID standard profile. You will find the source code to match the
block on the DVD "RFID Systems, Software & Documentation" (6GT2080-2AA20). You
can compile the source code into the machine code of the target system. You will also
find the documentation for this on the DVD.
● The third-party controller cannot be programmed according to IEC 61131:
The relevant interface is described in the section "Programming the communication
modules on PROFIBUS/PROFINET (Page 99)" of this manual. Programmers of a third-
party controller can use this interface to develop their own RFID function. The same or
similar data structures as in FB 45 can be reproduced on a third-party PLC in conjunction
with FB 45 description and the UDTs.
Requirements for using FB 45
FB 45 can access the communications module via any PROFIBUS/PROFINET master that
has the system function blocks SFB 52/53. It is irrelevant whether the
PROFIBUS/PROFINET master is integrated in the S7-CPU or plugged into the rack as an
add-on module (e.g. IM 467).
Please note that FB 45 uses acyclic frames (SFB 52/53). Older CPUs of the SIMATIC family
or small model series may not have these services. Please check this during configuration.
● STEP 7 version
The ASM 475 module requires a STEP 7 version ≥ V 5.1.

Data is transmitted to the tag and data is transmitted between the CM and FB 45 at the
same time. Usually no further time must be added for data transmission between the CM
and FB 45 so that the time tk calculated above represents the total duration of the command.
However, commands may require more time under the following conditions.
● A very large number of RFID channels are processed in parallel.
● Very few (or only one) system resources are available for non-cyclic frames.
● Slow transmission speeds are used on PROFIBUS.
● Other applications are running on the S7 which require the non-cyclic frame services
(SFB 52/53) of the SIMATIC very frequently.
● High-speed identification systems are used (e.g. RF300).

Figure 2-1 Configuration scheme of FB 45
Each FB 45 call points to a separate parameter data block (Params_DB, Params_ADDR),
which is defined by a UDT 10 The variables "command_DB_number" and
"command_DB_address" are stored in the UDT 10. These variables point to the RFID
command that will be executed with the tag.
UDT 20 is used to define the RFID command. Different commands or chains of commands
can be defined by calling UDT 20 several times (see Section "Command chaining"). The
variables "DAT_DB_number" and "DAT_DB_address" are defined in the UDT 20. This
variable definition forms the pointer to the user data which is simply referred to as DAT_DB
in this function manual. Tag data is stored there when it is read out. When using a write
command, the user must store his data before executing the command.

Figure 2-4 Setting the physical address assignment in UDT 10
In addition to the address (ASM_address), the RFID channel (ASM_channel) must also be
assigned uniquely. If a communications module is operated with two channels, a separate
UDT 10 must be defined for each channel. The "ASM_address" entry is the same. The
"ASM_channel" is set from 1 to 2.

Parameterizing 3
3.1 Parameter data block
Each RFID channel (reader) needs its own parameters. These are predefined in a data
structure as UDT 10 (with commentary in English) or UDT 11 (with commentary in German)
or UDT 14 (with commentary in Spanish). You need to call this UDT in a data block for each
RFID channel in which the widest range of variables are defined:
● INPUT parameters: These variables must be entered by the user once during
configuration (exception: command_DB_number/command_DB_address). Throughout the
run time it is not necessary to change or scan these parameters.
Please note that you need to execute an init_run after changing an INPUT parameter
before the new setting is activated (see Section "Programming a cold and warm restart").
● Control bits: The user starts his commands with these Boolean variables.
● Displays: The displays indicate the command progress to the user. Error analyses can be
performed easily.
● FB-internal variables: These variables are not relevant for the user. They must not be
changed by the application. Malfunctions and data corruption would otherwise ensue.
The following table shows the complete UDT. The relative addresses are shown in the first
column for programmers who prefer to address with absolute values.
