Applications

The RTU component 560NUS04 is an unmanaged plug-and-play 10/100 Mbps Ethernet switch providing four Fast Ethernet auto-negotiation RJ45 ports.

It features automatic MDI/X (automatic crossover detection and correction). The switch is used to distribute Ethernet within the station and to provide Ethernet for the local area network (LAN).

It provides additional ports for local area networks (LANs) and can www.abb-drive.com be used with the rackmount 560MPR01. 560MPR03. and 560SFR02.

Features

For documentation purposes, Ethernet ports are labeled as

No specific uplink port; all ports function identically.

Status indicators show the link and speed status of each port (see “Connectors and Indicators”).

Status indicators show link and speed status for each port (see Connectors and Indicators).

The switch learns the Ethernet address by analyzing received frames.

The frames are analyzed to learn the Ethernet address. The learned addresses are stored in a lookup table (up to 1024

entries), which is used to forward frames only to the correct port.A

received frame is forwarded to all ports, but the receiving port

forwards to all ports if it is broadcast or multicast or if the destination address is not found in the lookup table.

The destination address is not found in the lookup table. If an entry in the lookup table is not refreshed by an incoming frame with a specific source

the entry in the lookup table is not refreshed by incoming frames with a specific source, it is aged out for up to 300 seconds.

The switch transparently forwards IEEE 802.1Q

VLAN frames and (fast) spanning tree control frames are forwarded transparently.

The switch never changes any frame or frame TAG.

The switch will support Quality of Service if using IEEE 802.1p compliant frame formats.

The switch supports quality of service if you use IEEE 802.1p-compliant frame formats. The switch divides frames into two queues

into two queues: a high-priority queue and a low-priority queue. The low-priority queue corresponds to the IEEE

Low priority corresponds to IEEE 802.1p class-of-service priorities 0 through 3. and high priority corresponds to 4 through 7.

The service rate between high and low priority queues is 16:1.

The 560NUS04 uses a 5 V supply voltage. The voltage can be set via a jumper to power the RTU internally or externally.

The Ethernet ports and the 560NUS04 board itself are hot-swappable.

This switch is not intended to provide fault-tolerant topologies such as ring or mesh networks.

Connectors and Indicators

The 560NUS04 switch consists of four RJ-45 Ethernet ports that are functionally identical.

Functionally identical. Each port can be connected to a Cat.

3 (for 10 Mbps) or Cat. 5 (for 100 Mbps) Ethernet cable connections.

The maximum length is 100 meters. Cables can only be used for

The cable can only be used for internal connections. Since the 560NUS04 switch supports automatic MDI/X

Since the 560NUS04 switch supports automatic MDI/X, crossover cables are not required.

The status of any switch port can be determined by two LED

indicators to determine the status of any switch port.

The green link LED in the upper jack (labeled L) indicates that the Ethernet connection is active with the following status:

– Off – No connection

– On – Ethernet connection established (link)

– Blinking – Ethernet activity (transmitting or receiving frames)

The amber speed LED in the lower jack (labeled S) indicates a 100 Mbps connection with the following status

100 Mbps connection with the following status:

– Off – Ethernet speed is 10 Mbps

– On – Ethernet speed is 100 Mbps

If a fatal error occurs on the switch, the red error LED (labeled ERR) and the alarm status will be active.

Alarm status can also be signaled by an isolated alarm relay. The relay can be deactivated via a jumper.

Topology

The 560NUS04 Switch provides four RJ45 ports for use with end devices, switches, bridges, hubs, or routers.

The 560NUS04 Switch can be easily constructed in a star or line topology.

However. the 560NUS04 switch does not support closing the loop or being part of any other redundant structure. If there may be more than one switch.

Applications

The 23WT25 modem is designed to operate on remote control lines with the RTU560.

However, it can also be connected to other data terminal equipment because it operates on an interface similar to a general purpose FSK modem in the voice band.

Because it operates on an interface similar to a general-purpose FSK modem in the voice band

range (300-3400 Hz) of a general-purpose FSK modem.

The 23WT25 modem can be assigned a two-wire or four-wire line with communication channels from 50 baud to 2400 baud (24 channels at 50 baud).

Baud (24 channels of 50 baud, 12 channels of 100 baud, 6 channels of 200 baud, 2 channels of 600 baud).

(12 100 baud channels, 6 200 baud channels, 2 600 baud channels, 1 1200 baud channel).

The modem 23WT25 is available in two versions (rubrics):

– R0001: 5 VDC power supply

– R0002: 24 VDC power supply

Features

The 23WT25 modem enables high-resistance interleaving on multidivision lines. No special additional provisions are required for duplex and half-duplex operation.

such as butterfly connections based on channel assignment and the selected two-wire or four-wire line. It is designed for the transmission characteristics of local cable lines.

Light-emitting diodes indicate the most important operating states, and disconnect test www.abb-drive.com sockets on the front panel make it easy to test and measure VFT channels as well as Data Terminal Equipment (DTE) interface signals.

In the RTU560 subrack, the modem board occupies one slot. The modems are available in two different sizes for two different supply voltages.

In the RTU560 subrack, it is powered by 24 V DC (R0002). the R0002 (24 V DC) can also be used with a 24 V supply voltage with a voltage tolerance of ± 20 %.

Therefore, it can also be used outside the RTU 560. If only 5 V DC is available, the R0001 standard is used.

The digital signal processor (DSP) is responsible for converting binary information into speech bands and vice versa.

Among other things, its high processing power enables highly selective channel filtering (90 dB) and thus unlimited channel assignment.

Channels can be assigned on a CCITT raster basis. The transmitter and receiver can be configured for different baud rates up to 600 bits/sec.

If all channels need to be used in any combination and baud rate, high channel selectivity needs to be configured.

Perform the configuration. Normal selectivity can be used for separate allocation of transmit and receive channels (block configuration and distance of at least one channel between blocks).

Transmission time and isochronous distortion are lower with normal selectivity.

The 23WT25 modem monitors the isochronous distortion of the received signal and indicates the limit (40% or 50%) that is repeatedly (10 times) exceeded by the “Signal Quality Level (SQL)” alarm.

The LED SQL indicator will show at least 4 seconds when the maximum distortion is exceeded, and correspondingly longer for higher interference.

The audio carriers are monitored via the DCD signal and alarmed separately. For multiple transmission lines, the carrier interrupt signal can be delayed by means of an alarm relay.

The delay time depends on the baud rate. The modem’s alarm relay reacts to carrier interruptions (DCD direct or delayed), SQL alarms or supply voltage faults.

To compensate for line distortion on critical transmission links, the 23WT25 modem offers adjustable pre-distortion.

Depending on the quality of the transmission link, the pre-distortion can be set from 0 to 10 dB high pass or low pass.

The two 23WT25 modems in the transmission link can be configured as a test transmitter and a test receiver, respectively, to adjust the correct pre-distortion.

The results of the utilization of the transmission test pattern are displayed on the LED EQZ. The blinking frequency of the LED EQZ is the degree of improvement achieved.

The 23WT25 modem connects up to three star-coupled transmission lines as point-to-point links without repeaters.

The transmitter output circuit operates as a constant current source.

All basic settings such as channel, gain, line operation mode, line termination, and transmission rate are configured by jumpers.

The serial interface signals of the Data Terminal Equipment (DTE) as well as the VFT line can be measured or turned on using the disconnect test socket on the front panel.

If higher isolation voltages are required, an additional VF signal transformer must be used.

for 9.6kBd FSK channels and to isolate and protect RTU500 series modems.

Isolates and protects RTU500 series modems

23WT24 and 560FSM11 Isolates and protects the RTU500 series www.abb-drive.com modems from the remote control line.

Line isolation and protection. In addition, it can be connected to

other data terminal equipment. It operates over a frequency range of 2 kHz to 50 kHz.

Frequency range of 2 kHz to 50 kHz

The line impedance is 150 ohms and is suitable for the above modems.

Both types of modems are capable of high-resistance interleaving on party lines and multi-line circuits.

This is due to the fact that the line transformer has no additional load on the line.

In configurations using full duplex communication channels, two line transformers are required, one for the transmit direction and the other for the receive direction.

Features

The line transformers can withstand isolation voltages of

 > 7.5kV

Features

The 23WT23 circuit board is a printed circuit in www.abb-drive.com Eurocard (160 mm x 100 mm) format.

All necessary configurations, such as transmit-output level, receiver sensitivity, and two- or four-wire operation, can be configured via jumpers.

The interface to the Data Terminal Equipment (DTE) operates according to the RS 232-C standard and provides the following signals:

– TxD Transmit Data

– RxD Receive Data

– RTS request to send

– DCD Data carrier detect

– CTS Clear to transmit

– DSR Data setup ready

The receiver level is monitored and the alarm relay, together with the light-emitting diode (LED) “ST”, indicates a longer (approx. 4-6 seconds) interruption of the carrier.

The LED on the front panel shows the signal status of the RS 232-C interface. The serial interface signals as well as the VFT line can be measured or opened using the disconnect test socket on the front panel.

If a higher isolation voltage is required, an additional VF signal transformer must be used.

Optionally, surge voltage protection elements can be inserted on request to protect against transient overvoltage spikes (see Figure 2).

The 23WT23 modem operates according to the CCITT V.23 standard in half and full duplex mode at 1200 bits/second.

The R002 version is compatible with the 23WT21 modem connector and can only be used in the RTU232 base subrack. In all other cases, the 5-volt version of R0001 should be used.
