3.2SIMATIC RF300
SIMATIC RF300 is an inductive identification system specially designed for use in industrial production for the control and optimization of material flow.
Thanks to its compact dimensions, RF300 is the obvious choice where installation conditions are restricted, especially for assembly lines, handling systems and workpiece carrier systems. RF300 is suitable for both simple and demanding RFID applications and it stands out for its persuasive price/performance ratio.

System overview 3.2 SIMATIC RF300
Low-performance applications
With the cost-effective IQ-Sense interface, RF300 provides an especially favorable solution concept for low-performance applications.
Medium-performance applications
RF300 in conjunction with ISO tags provides a cost-effective solution for mediumperformance applications.
High-performance applications
The high-performance components of RF300 provide advantages in terms of high data transmission rates and storage capacities.
File handler functionality
In addition to standard addressing, the ASM 456 interface module in conjunction with the FC 56 offers a file handler functionality. The required parameters correspond to those of MOBY I which are described in the FC56 documentation (http://support.automation.siemens.com/WW/view/en/18690683).
Available ASMs can be found in an overview table in Chapter "System integration, Introduction (Page 209),Table 8-1).

Description
A communication module (interface module) is used to integrate the RF identification system in controllers/automation systems.
The reader (read/write device) ensures inductive communication and power supply to the transponder, and handles the connection to the various controllers (e.g. SIMATIC S7) through the communication module (e.g. ASM 475).
The transponder (data memory) stores all data relevant to the production process and is used, for example, instead of barcode.

Conventions
The RF310R, RF340R and RF380R readers are equipped with an integral antenna, whereas the RF350R reader is operated over an external antenna. In this system manual, the term "Reader" is used throughout even where it is actually referring to the antenna of the reader.
SIMATIC RF300 is primarily used for non-contact identification of containers, palettes and workpiece holders in a closed production circuit. The data carriers (transponders) remain in the production chain and are not supplied with the products. SIMATIC RF300, with its compact transponder and reader enclosure dimensions, is particularly suitable in confined spaces.
Main applications
●Mechanical engineering, automation systems, conveyor systems
●Ancillary assembly lines in the automotive industry, component suppliers
●Small assembly lines

System Manual, 11/2009 - Zwischenstand 17.09.2009, A5E01642529-04 |
System overview 3.3 System configuration
Application examples
●Production lines for engines, gearboxes, axles, etc.
●Assembly lines for ABS systems, airbags, brake systems, doors, cockpits, etc.
●Assembly lines for household electrical appliances, consumer electronics and electronic communication equipment
●Assembly lines for PCs, small-power motors, contactors, switches
Advantages
●Reading and writing of large data volumes within a short time results in shorter production cycle times and thus help to boost productivity
●Can be used in harsh environments thanks to rugged components with high degree of protection
●Simple and low-cost system integration into SIMATIC S7 and PROFIBUS (TIA)
●Shorter commissioning times and fewer plant failures and downtimes thanks to integral diagnostic functionalities
●Cost savings thanks to maintenance-free components
The SIMATIC RF300 system is characterized by a high level of standardization of its components. This means that the system follows the TIA principle throughout: Totally Integrated Automation. It provides maximum transparency at all levels with its reduced interface overhead. This ensures optimum interaction between all system components.
The RF300 system with its flexible components offers many possibilities for system configuration. This chapter shows you how you can use the RF300 components on the basis of various example scenarios.
In assembly lines, such as in engine manufacturing, many work steps are completed in succession. Automated or manual assembly work is carried out at the individual workstations in relatively short periods of time. The special features of the RF300 tags, which stand out for their large data memory and high transmission speeds, bring about many advantages in regard to the production unit numbers of such plants.
The possibility of saving large volumes of data means savings in terms of data management on the HOST system and considerably contributes to data security. (redundant data management, e.g. HOST database, or controller and data carrier)
Advantages at a glance:

System overview
3.3System configuration
●Redundant data storage on the basis of large memory, availability of decentralized data
●High data rate
●Data management savings on the host system
Characteristics of the scenario
In this example scenario, engine blocks that are placed on metal pallets are conveyed on an assembly line. The engines are assembled piece-by-piece at the individual workstations. The SIMATIC RF340T RFID tag is securely affixed on the underside of the pallet. The transport speed is approx. 0.5 m/s.
In this scenario, it is an advantage that the tag can be directly secured to metal on the metal pallets. The small-dimensioned SIMATIC RF310R reader is integrated in the conveyor elements in such a manner that it can communicate with the tags from below. Thus, it is not necessary to align the pallets or to attach several tags.
The data of the entire production order (5000 bytes) is stored on the tag. This data is read at each workstation and changed or supplemented depending on the workstation, and then written back again. Thus, the status of the engine block assembly can be determined at any point in time, even if there is a failure at the HOST level.
Thanks to the extremely high data rate, a very short cycle time for the work steps can be factored in, which results in high end product unit numbers (engines).
The entire production order that is saved on the tag can also be manually read via the WINLC terminal located at each workstation. This means that virtually no additional data management is required on the control PC.
The production order data can also be read for servicing purposes via the mobile SIMATIC RF310M handheld terminal.

Figure 3-3 Example of engine block production
Containers of varying sizes are conveyed to picking workstations in a delivery center. There, the individual goods are removed and packed in cartons according to the delivery note. These cartons are marked with low-cost transponder labels and sorted to small or large packaging workstations (according to the delivery note) by being guided or transported via the corresponding conveyor system. The containers are marked using the MDS D100 ISO tag.
Advantages at a glance:
●Decision points in the conveyor system can be installed in a more favorable way (mechanically)
●Different sizes of containers with different depths can be identified due to the range

System overview
3.3System configuration
●In contrast to bar codes, tags can also be written to
●Different types of tags can be processed using one and the same reader
Characteristics of the scenario
In this example scenario, containers of varying sizes are conveyed on a conveyor system. Only the unique identification number (8 bytes) is read. The containers to be picked are sorted to the corresponding workstations. The maximum transport speed is 1.0 m/s.
In this scenario, it is an advantage that the RF380R reader can read and write the tags at different distances on the containers without a great deal of mechanical or control system effort due to the reading range.
During the picking process, the goods are immediately placed in different containers or packed in cartons depending on the destination (small packaging or large packaging station). The containers are equipped with the MDS D100 ISO tag. The low-cost "one-way tag" (label) is used on the cartons: it is simply glued onto the carton. Thus the goods can be identified at any time. Again, one and the same reader is used for this. The maximum transport speed is 0.8 m/s.
In addition, flexible identification is possible at each location and at any time using the mobile SIMATIC RF310M handheld terminal.

RF300 system planning |
4 |
Assess your application according to the following criteria, in order to choose the right SIMATIC RF300 components:
●Transmission distance (read/write distance)
●Tracking tolerances
●Static or dynamic data transfer
●Data volume to be transferred
●Speed in case of dynamic transfer
●Metal-free rooms for transponders and readers
●Ambient conditions such as relative humidity, temperature, chemical impacts, etc.
The reader generates an inductive alternating field. The field is strongest near to the reader. The strength of the field decreases in proportion to the distance from the reader. The distribution of the field depends on the structure and geometry of the antennas in the reader and transponder.
A prerequisite for the function of the transponder is a minimum field strength at the transponder achieved at a distance Sg from the reader or the ANT1. The picture below shows the transmission window between transponder and reader or ANT1:

RF300 system planning
4.1 Fundamentals of application planning
From the diagrams above, it can also be seen that operation is possible within the area between Sa and Sg. The active operating area reduces as the distance increases, and shrinks to a single point at distance Sg. Only static mode should thus be used in the area between Sa and Sg.
Determining the width of the transmission window
The following approximation formula can be used for practical applications:
% y /
B:Width of the transmission window
L:Length of the transmission window
Tracking tolerances
The width of the transmission window (B) is particularly important for the mechanical tracking tolerance. The formula for the dwell time is valid without restriction when B is observed.
Secondary fields in the range from 0 to 20 mm always exist.
They should only be applied during planning in exceptional cases, however, since the read/write distances are very limited. Exact details of the secondary field geometry cannot be given, since these values depend heavily on the operating distance and the application.
