– RS2-4TX/1FX EEC – RS2-4TX/1FX-ST EEC– RS2-4TX/1FX-SM EEC

– RS2-4TX EEC

in short RS2-xTX/xFX EEC, are switchesespecially designed for use in industrialenvironments. They support ETHERNET 10MBit/s and Fast ETHERNET 100 MBit/s.

The Rail Switch modules support switchedETHERNET networks in accordance withIEEE standard 802.3 using copper and fiberoptic technology. The switch modules areplugged onto the standard DIN rail.

The RS2-3TX/2FX… modules have three10/100 MBit/s twisted pair ports(10/100BASE-TX, RJ45 connectors) and two100 MBit/s fiber optic ports (100BASE-FX,Duplex SC connector).It is possible to connect up to three DTEs orother TP/TX network segments to the TP/TXports using twisted pair cabling. Two furtherDTEs or optical network components can beconnected to the fiber ports.

The RS2-4TX/1FX… modules have four10/100 MBit/s twisted pair ports(10/100BASE-TX, RJ45 connectors) and one100 MBit/s fiber optic port (100BASE-FX,Duplex SC connector or ST connector onR2-4TX/1FX-ST EEC).The RS2-4TX EEC module has four 10/100 MBit/s twisted pair ports(10/100BASE-TX, RJ45 connectors).It is possible to connect up to four DTEs orother TP/TX network segments to the TP/TXports using twisted pair cabling. One furtherDTE or optical network component can beconnected to the fiber port (with RS2-4TX/1FX…).

The TP ports support auto negotiation,autopolarity and autocrossing.

1. Functional description

The 10/100BASE-T(X) ports of a RS2-xTX/xFX EEC represent a terminal connec-tion for the connected LAN segment. Youcan connect single devices or complete net-work segments.

1.1 FRAME SWITCHING FUNCTIONSStore and ForwardAll data received by the RS2-xTX/xFX EECfrom the system bus or at the ports is stored and checked for validity. Frames > 1536 bytes as well as fragments (< 64bytes) are discarded. The RS2-xTX/xFX EECforwards the valid frames.

Multi address capabilityA RS2-xTX/xFX EEC learns all sourceaddresses per port. Only packets with– unknown addresses– addresses learnt at this port– a multi/broadcast addressin the destination address field are sent tothis port.A RS2-xTX/xFX EEC learns up to 1,000addresses. This becomes necessary if morethan one terminal device is connected toone or more ports. In this way several inde-pendent subnetworks can be connected to aRS2-xTX/xFX EEC.

Learnt addressesA RS2-xTX/xFX EEC monitors the age of thelearned addresses. The RS2-xTX/xFX EECdeletes address entries from the addresstable which exceed a certain age (300seconds).Note: Restarting deletes the learnedaddress entries.

Tagging (IEEE 802.1Q)The IEEE 802.1 Q standard designates theVLAN tag to be included in a MAC dataframe for the VLAN and prioritizing func-tions. The VLAN tag consists of 4 bytes (2bytes tag protocol identifier TPID, 2 bytestag control information TCI). It is insertedbetween the source address field and thetype field. Data packets with a VLAN tag aretransmitted unchanged by the RS2-xTX/xFXEEC.

1.2 SPECIFIC FUNCTIONS OF THE TP/TX INTERFACELink controlThe RS2-xTX/xFX EEC monitors the connec-ted TP/TX line segments for short-circuits orinterrupts using regular Idle signals inaccordance with IEEE standard 802.310/100BASE-T/TX. The RS2-xTX/xFX EECdoes not transmit any data to a TP/TX seg-ment from which it does not receive an Idlesignal.

Note: A non-occupied interface is assessedas a line interrupt. The TP/TX line to termi-nal equipment which is switched off is like-wise assessed as a line interrupt as the de-energised bus coupler cannot transmit Idlesignals.

Auto polarity exchangeIf the receive line pair is incorrectly connec-ted (RD+ and RD- switched) polarity is auto-matically reversed.

AutocrossingThe RS2-xTX/xFX EEC detects the transmitand receive pairs (MDI, MDI-X). The RS2-xTX/xFX EEC automatically con-figures its port for the correct transmit andreceive pins. Consequently it does not matter whether you connect devices using a cross-over or straight cable.

1.3 SPECIFIC FUNCTIONS OF THEF/O INTERFACELink controlThe RS2-xTX/xFX EEC monitors the connec-ted F/O line for interrupts using idle signalsduring frame pauses in accordance withIEEE standard 802.3 100BASE-FX. The RS2-xTX/xFX EEC transmits no data to a F/Oline from which it is receiving no idle signal.

Low Light DetectionIf the optical input power decreases belowthe low light threshold the transmit andreceive path will be disabled for data andthe idle signal will be transmitted.

Far-End FaultThe optical transmission distance of theRS2-xTX/xFX EEC can be monitored inreceiving direction as well as in transmitting

direction, if the other side also supports Far-End Fault. If the other side does not supportFar-End Fault, the optical transmissiondistance is monitored only in receivingdirection.Far-End Fault is sent, if the optical inputpower at the optical port has fallen underthe low light level. If Far-End Fault is re-ceived, the link stays inactive (DA/STAT LEDdark).

1.4 FURTHER FUNCTIONS AND FEATURESResetThe RS2-xTX/xFX EEC will be reset by thefollowing action:– input voltages fall below a threshold

After a reset the following action is carriedout:– initialization

100 Mbit/s connection (FX port)The 100 MBit/s ports of the RS2-xTX/xFX EEC,- one port on the RS2-4TX/1FX…- two ports on the RS2-3TX/2FX… supportthe IEEE 802.3 100BASE-FX FDX standard.They use a duplex SC connector or a STconnector (on RS2-4TX/1FX-ST EEC). Each100 MBit/s port allows one further DTE oran optical network component to beconnected.

5pin terminal blockThe supply voltage and the indicatorcontact are connected via a 5pin terminalblock. If the terminal block is fitted thewrong way round, the device will still workcorrectly.

z Warning!The RS2-xTX/xFX EEC equipmentsare designed for operation with asafety extra-low voltage. Thus, theymay only be connected to the sup-ply voltage connections with PELVcircuits or alternatively SELV circuitswith the voltage restrictions inaccordance with IEC/EN 60950.

– Voltage supply: Redundant voltage sup-plies are supported. Both inputs aredecoupled. There is no load distribution.With redundant supply, the power packsupplies the RS2-xTX/xFX EEC only withthe higher output voltage. The supply vol-tage is electrically isolated from the hou-sing.

– Indicator contact: The indicator contact is used to supervisethe functions of the RS2-xTX/xFX EEC andthus facilitates remote diagnosis withoutmanagement software.Contact interrupt indicates the followingby means of a potential-free indicatorcontact (relay contact, closed circuit):– the failure of at least one of the two

supply voltages (supply voltage 1 or 2 < 9.6 V).

– a permanent fault in the RS2-xTX/xFXEEC (internal voltage supply).

– the faulty link status of at least one port.The indication of the link state on theRS2-xTX/xFX EEC can be masked on aport-by-port basis using the DIP swit-ches LA1 to LA5 (LA1 to LA4 on RS2-4TX EEC).State of delivery: link test is activated.
