.1General

Thank you very much for buying a rail line series device. This document describes the Ethernet interface functions of

field bus coupler RL ETH, which is called bus coupler in the following description, and the system capability of the

various module versions of the rail line series (CI45-1xx-2.., KS45-1xx-2..., TB45-1xx-2....), called “function module” in

the following description. The term “ device” applies to both bus coupler and function modules.

Bus couplers with a Ethernet - 150 interface permit the transmission of process, parameter and configuration data.

Field bus connection is via a RJ 45 socket at the top of the bus coupler. The serial communication interface facilitates

connections to supervisory systems, visualization tools, etc.

Another standard interface is the non-bussable ‘BluePort®’ front-panel (PC) interface. It is used for direct connection of

the ‘BlueControl®’ tool which runs on a PC.

The most important features of the bus connection with their physical and electrical properties are:

•Transfer rate

The Ethernet coupler operates as a Modbus/TCP server with a maximum transfer rate of 10 / 100 Mbit/s

•Clients

The Ethernet bus coupler permits communication with up to 4 clients using the TCP/IP protocol

•Physical layer

10/100BaseT

•Connection

RJ45 socket

4.3 Mounting

Connection between bus coupler and function modules is via bus connectors, which snap onto the top-hat rail. Several

devices are mounted side by side with high packing density. The bus links between the devices are made directly via

the bus connectors.

The instruments are provided for vertical mounting on 35 mm top-hat rails to EN 50022.

If possible, the place of installation should be exempt of vibration, aggressive fluids (e.g. acid, lye), liquids, dust or

other suspended matters.

Instruments of the rail line family can be mounted directly side by side. For mounting and dismounting, the min.

distance above and below the instrument from other equipment should be 8 cm.

For installation of the bus connection, proceed as follows:

1Snap on the bus connectors (delivered with the device) onto the top-hat rail

2For high-density mounting, push the bus connectors together.

3Clip the instruments onto the top-hat rail via the bus connectors

- the internal system bus connection is ready!

+Please, mount the bus coupler in the leftmost position and fit the function modules right of the bus coupler

in the required order.

grail line instruments do not contain parts for which maintenance is compulsory and need not be opened by

the customer.

aWarning

A field bus coupler can energize max. 16 function modules. For connecting a higher number of modules RL

PWR power supply modules must be used.

4.4 Electrical connections

4.4.1 Bus coupler supply voltage

A system comprising bus coupler and one or several function modules is energized centrally via the bus coupler.

Central energization reduces the wiring expenditure considerably.

aWarning

Energization at the function modules is not permissible.

gA bus coupler can energize max. 16 function modules. For extension possibilities, see chapter 4.4.2.

4.4.2 Energization via RL PWR power supply module

Power supply module RL PWR is used for energization of function modules with system interface via the bus connector

in the top-hat rail.

For connecting a higher number of function modules to the bus coupler than permissible for energization, additional

power supply modules must be used.

Applications:

•Supplementary energization of additional function modules

•Repartition to different installation levels (e.g. two rows in a control cabinet)

•Construction of separate potential levels

•A power supply module can energize up to 16 function modules.

aWarning

Energ. at the function modules is not permitted.

aWarning

High-density mounting with other partial systems is not permissible.

gCascade connection of power supply modules is not permissible (see above).

4.4.3 Physical connection

Ethernet connection is via the front-panel bus coupler RJ45 interface.

10/100BaseT is used as physical layer.

Physical connection is via Ethernet using twisted two-wire cable (CAT5 cable, 8-pole in RJ-45 connection technique).

The connection is made by means of an RJ-45 socket.

4.4.4 Cable layout

For connecting the field instruments, suitable bus cables for the application must be used. The wiring must comply

with the general hints and regulations (e.g. VDE 0100):

•Cable layout in buildings (inside and outside cabinets)

•Cable layout outside buildings

•Potential compensation

•Cable screening

•Measures against interference voltages

•Length of tap line

In particular, the following information must be taken into account:

•With RS 485 technology, max. 32 field units can be connected in a segment at a bus cable. Several segments

can be coupled by means of repeaters.

•The bus topology should be a line of max. 1000m length per segment. Extension by means of repeaters is

permissible.

•The bus cable connection must be a “daisy chain” between field instruments rather than star-shaped .

•If possible, tap lines should be avoided to prevent reflections causing communication trouble. With higher

transfer rates, tap lines are not permissible.

•The general hints for low-interference signal and bus cable wiring are applicable (see operating note „EMC –

General information“ (9407-047-09118)).

To increase the transfer safety, pairwisely twisted and screened bus cables can be used.

4.4.5 Screening

The type of screening connection is dependent mainly on the expected interference.

•For suppression of electric fields, one end of the screening must be connected to earth. Always realize this

measure at first.

•However, suppression of interference due to an alternating magnetic field is possible only, when the both ends

of the screening are connected to earth. With earth circuits, however, note the screening effect is reduced by

galvanic interference on the reference potential.

•If several devices are linked to a single bus, the screen must be connected at each device, e.g. by means of

screen clamps.

•Short distance bus screening must have a large-surface, low-resistance connection to a central protective earth,

e.g. via screening terminals

4.5.1 TCP port

The ModbusTCP server expects TCP messages on TCP port 502. This port is reserved for ModbusTCP.

gWhen Port 502 is connected, LED ‘BS’ is lit.

4.5.2 IP address and IP netmask

The IP address can be determined in two different ways:

•via parameters by means of the BlueControl®engineering tool

•via BOOTP (Bootstrap protocol)

+For detailed information on the modes and settings, see chapter 4.6 .

The IP netmask is adjustable via parameter “IPSub”. The default value is 255.255.255.0 .

4.5.3 Connections

gRL ETH can operate max. 4 connections at a time. Up to 16 messages can be handled.

4.6 IP address definition

The unique MAC-ID is specified in item “Mac-Adr.” on the type label.

The IP address can be determined using two different methods.

+The allocated IP address must be unique in the network.

4.6.1 Parameter setting via BlueControl®

The IP address (4 byte) and subnet mask (4 bytes) can be set in the coupler via the BlueControl®software.

gIf IP address 0.0.0.0 is specified, no valid address is provided (factory setting). In this case, the address can be defined

via the BootP protocol.

4.6.2 BOOTP (Bootstrap Protocol)

BOOTP is a TCP/IP configuration service. A BOOTP client sends a BOOTREQUEST broadcast via address

255.255.255.255 into the network. BOOTP awaits a server reply (BOOTREPLY) during a defined time. Unless a reply is

received, the client sends the broadcast again. BOOTP uses the UDP protocol for communication.

Procedure:

To determine the IP address of Ethernet coupler RL ETH via BOOTP, a BOOTP server replying the Ethernet

coupler inquiry must be provided.

On Ethernet coupler RL ETH, the switch for the IP address must be set to 0.0.0.0.

After switching on the Ethernet coupler, the sequence described above is started, the address is determined

and stored in the Ethernet coupler EEPROM.

When starting up the Ethernet coupler for the next time, the IP address is loaded from the EEPROM.

+In networks in which the IP addresses are defined via a DHCP server, a special BOOTP server is not required. The

DHCP server allocates an IP address to Ethernet coupler RL ETH dynamically.

.5System design

Up to 16 function modules can be connected and energized at a bus coupler. System extension is possible by using

power supply modules:

•Up to 62 function modules can be addressed logically by a bus coupler.

•Up to 4 installation levels can be built up.

•The max. permissible extension is 10 m.

5.1 System structure

Using power supply modules offers many advantages:

•The number of function modules connectable to a bus coupler can be extended.

•The function modules can be distributed to different levels in the control cabinet.

A potential-isolated energy supply is possible.

gThe overall system length including cables must not exceed 10 m. Max. 3 m cable length between two

groups is permissible.

5.1.1 Hints for connection

For connecting the function modules energized by the bus coupler and the function modules energized by the power

supply module, proceed as follows:

1Insert a connector (e.g. 9407-998-07141) on the right side of the group with the bus coupler into the bus connector

in the top-hat rail.

2Insert a connector (e.g. 9407-998-07131) on the left side of the group with the power supply module into the bus

connector.

3Use twisted and screened two-wire bus cable.

Connect conductor 1 with the lower contact S5 and conductor 2 with contact S4.

4Terminate the system bus with a terminating resistor LT = 100.

For this, insert a connector (e.g. 9407-998-07141) on the right side of the last group with a power supply module

into the bus connector. Connect the resistor across terminals S4 - S5.
