Introduction
1.1 Overview
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
● The data structures are set up conveniently via user-defined data types (UDTs). The
● Data is transmitted to and from the CM and commands are executed on the CM at the
● The use of symbolic names enhances the clarity in the user program, even where
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:
