5.2 SIMATIC RF610R

5.2.1 Description

5.2.1.1 Overview

The SIMATIC RF610R is a stationary reader in the UHF frequency band with an integrated antenna.

The maximum transmit power is 400 mW, the radiant power of the internal antenna is 200 or 250 mW ERP / 400 mW EIRP. The interfaces (Ethernet, power supply) are located on the lower front edge. These interfaces can be used to connect the reader to the power supply and a PC for parameter assignment.

The degree of protection is IP67.

Requirement for external power sources

The reader must only be supplied with power by power supply units that meet the requirements of LPS (Limited Power Source) and NEC Class 2.

Requirement for external power sources

The reader must only be supplied with power by power supply units that meet the requirementsof limited power source (LPS) and NEC Class 2.

Spécification des sources de tension externes

L'alimentation du plot de lecture/écriture doit être exclusivement assurée par des blocs d'alimentation conformes aux spécifications des sources à puissance limitée (Limited Power Sources LPS) et de NEC class 2.

Notes on connectors and cables

The cables with open cable ends (6GT2891-4EH20, 6GT2891-4EH50) have an 8-pin M12 plug at one end, while the other end of the cable is "open". There are 8 color-coded single wires there for connecting to external devices.

The product range includes additional cables of the type 6GT2891-4Fxxx (2 to 50 m) with an M12 connector at both ends. These cables can be used as extension cables. Long cables can be shortened if necessary.

NOTICE

Insulate unused single wires

Unused single wires must be insulated individually to prevent unwanted connections of signal lines.

NOTICE

For long cables: Adapt the power supply and transmission speed

Note that even with long cables, the supply voltage of 24 VDC must always be guaranteed. Note also that the transmission speed on the serial interface must, if necessary, be reduced.

SIMATIC standard cables (e.g. 6GT2891-4FN10) have a loop resistance of 160 mOhm / meter. This results in a voltage drop of 0.8 volts on the 24 V cable for every 10 meters of connecting cable and with a power requirement of 500 mA. If the power requirement increases through the use of the digital inputs/outputs, the voltage drop increases accordingly.

5.2.1.5 Ground connection

Due to the potential-free design of the reader, no earthing measures are required.

5.2.2 Planning operation

5.2.2.1 Internal antenna

Minimum mounting clearances of two readers

RF610R has an internal circular antenna. To prevent the antenna fields from overlapping, always observe the recommended minimum distances between two readers as described in the section "Reciprocal influence of read points (Page 47)".

Dense Reader Mode (DRM)

The readers can also interfere with each other (secondary fields), if the channels (Reader TX, Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader channel, we recommend that the Dense Reader Mode (DRM) is used.

Note Protective cap

If you only use the internal antenna of the reader, we recommend that you close the external, unused antenna connector on the reader using the protective cap.

Antenna diagram RF610R (ETSI)

The following radiation diagrams show the directional characteristics of the internal antenna of the RF610R (ETSI) reader. For the spatial presentation of the directional characteristics, the horizontal plane (azimuth section) as well as the vertical plane (elevation section) must be considered. This results in a spatial image of the directional radiation pattern of the antenna.
