Features

Ethernet ports are labeled 1 to 4 for documentation purposes.

SDSL ports are connected via the backplane.

There are no specific uplink ports. All ports are functionally identical.

The link and speed status of each Ethernet and SDSL port is indicated by status LEDs (see “Connectors and Indicators”).

The switch learns Ethernet addresses by analyzing received frames and stores them in the query.

The switch learns Ethernet addresses by analyzing received frames and stores them in a lookup table (up to 2048 entries),

used to forward frames only to the correct port. If the frame is

widecast or multicast, or the destination address is not found in the lookup table, the received frame is forwarded to the correct port.

then the received frame is forwarded to all ports except the receive port.

Receive port. If an entry in the lookup table is not refreshed by an incoming frame with a specific source address

then it is aged out for a maximum of 304 seconds.

Maximum 304 seconds (default, configurable).

For IEEE 802.1Q VLAN frames, the switch can be configured in VLAN or transparent mode. In transparent mode

the switch does not change any frames or frame TAGs; in VLAN

mode, the switch can be configured to support a variety of applications, such as

trunking or access ports.

The switch will support quality of service if it uses an IEEE 802.1p-compliant frame format.

The switch can support quality of service if the frame format is IEEE 802.1p compliant. The switch can divide frames

into up to four queues, which can be configured as priority queues or weighted fair queues.

The switch uses a 5 V supply voltage, which can be set as the internal RTU power supply or via a jumper.

It can be set to internal RTU power or external power via jumpers.

The components themselves, the Ethernet ports, as well as the SDSL

connections and RS232 interfaces are hot-swappable.

Use the 560NMS24 unit as a repeater for longer distance transmission.

Communication module for RTU560 with 32-bit CPU

– 2 serial communication interfaces (RS-232 or RS-485) for remote communication

– 2 Ethernet interfaces (10/100BaseT)

– 1x USB port

– 1x serial peripheral bus

– Battery buffered real-time clock

Applications

The 560CMR01 Communication Unit is one of the CMU modules of the RTU560 product family.

Its main tasks are

– Managing and controlling the I/O modules via the serial I/O bus interface.

– Read process events from the input modules.

– Send commands to the output modules.

– Communicate with the control system and the local HMI system via the serial interface (RS232) and the Ethernet 10/100BaseT interface.

– Communicates with sub-RTUs, IEDs, or multimeter devices via interface (RS485) and Ethernet interfaces.

– Manages the time base of RTU560 product line stations and synchronizes I/O modules.

– Handles the dialog between the RTU560 product line and a web browser through the LAN interface.

Within the RTU560 chassis, the board occupies . The communication unit handles communication protocols based on Ethernet and UART characters.

The unit is equipped with a battery-buffered real-time clock (RTC).

The unit is available in two versions:

– R0001: with standard network security

– R0002: with security chip with advanced network security features

The RTU560 enters the valid time immediately.

Applications

RTU560 product line units can be synchronized with the standard time of the longwave transmitter DCF77 using the module 560RTC02.

The RTU560 reads the time and date from the module 560RTC02 and synchronizes its internal clock with standard time via minute pulses.

The RTU560 synchronizes its internal clock with standard time by means of minute pulses. The use of the module 560RTC02 ensures that the indications of several end devices are synchronized when they contain time information.

Features

The longwave DCF 77 transmitter can be reliably received within a distance of approx. 1500 kilometers from Frankfurt/Main in West Germany, as well as in many parts of Europe.

If the reception level is sufficient, the module 560RTC02 will synchronize with standard time and receive the date and time within three minutes.

The communication unit (CMU) is synchronized with DCF 77 via the MIN1 pulse front. the CMU reads the time and date via the RTU system bus.

In the event of radio interference or DCF 77 interruption, the clock on the 560RTC02 will continue to use a high precision quartz clock. The internal condenser allows the

560RTC02 to continue to control the clock (approximately 150 hours), even when the station is turned off. Upon power-up, the RTU560 will have valid time immediately.

If the DCF 77 signal fails for more than 2.5 hours or the 560RTC02 is not synchronized, the alarm relay contacts close.

In addition to the minute pulse output for RTU560 synchronization, there is also a minute pulse output which is connected to the module via an optocoupler (MIN2).

The time, date and status can be read out every minute via the serial data output interface RS232.

Four light-emitting diodes on the front panel of the 560RTC02 real-time clock are used to indicate the following operating states:

– ST: Brief board alarm

– FR: Free-running 560RTC02 not synchronized with DCF 77

– CD: Carrier Detect Carrier Detect

Receiver signal strength level; optimal positioning of the antenna for maximum reception

– MN: Pulse per minute blinking
