For your safety

Warning!

The TH LINK contains electronic components

sensitive to electrostatic discharges. Damages

due to electrostatic discharge can lead to

premature failure of components or intermittent

faults at a later stage.

Before installing the TH LINK, divert the

electrostatic discharge away from your body and

the tools used.

– Carefully plan the integration of the TH LINK into an existing

system and ensure proper function of the system after
installation.

– The TH LINK may only be installed or uninstalled by qualified,

trained electrical engineering personnel.
When installing the TH LINK, observe the regulations for
handling electric components in accordance with VDE 0100. In
addition, you must also observe the valid safety and accident
prevention regulations (UVV) when operating the device within

the jurisdiction of the Federal Republic of Germany.
– Observe the IEC 61158 standard.
– Always install the TH LINK on a suitable top-hat rail (mounting

rail).
– Cables used for the connection must not apply any mechanical

forces to the TH

LINK.

6

Trebing & Himstedt Prozeßautomation GmbH & Co. KG | TH LINK

For your safety

– High temperature differences between the storage site and

installation site can result in condensation within the case,
which may cause the TH

LINK to become damaged.
In case of high temperature differences, please wait at least
three hours before operating the TH

LINK.

– Lock the connected plug (PROFIBUS) using the srew

connections intended for this purpose.

Disposal

The TH LINK must be disposed of separately
from normal household waste in accordance
with the 2002/96/EC (WEEE) directive.

connects the higher-level network structure with the field level. It
forms the basis for the Trebing + Himstedt products TH SCOPE,
PROFIBUS Scope, Trebing + Himstedt DTM Library, TACC and
TH OPC Server DP.

The TH LINK is quick to assemble/install and to put into
operation. The delivered default configuration allows start-up in
only a few minutes. In order to prevent network disruptions by
unauthorized configuration changes, all configuration functions
are protected by user administration.

The TH LINK includes the free-of charge TH SCOPE easy.

Features

– Connection between higher-level network and field level
– Access to the PROFINET/Industrial Ethernet network
– Basis for TH SCOPE, PROFIBUS Scope, Trebing + Himstedt

LINK is a passive station in the bus. Therefore the TH LINK

LINK can be used as a class 2 master in connection with

an external master application (FDT or Emerson's AMS Suite).
The TH LINK is passive until a PROFIBUS address is set in the

master application and the communication is started. Then the
TH

LINK is an active station.

Configuring the TH LINK in the Ethernet network

Configuration method (DHCP/Manual)

There are two connecting options to choose from, depending on
your network:

– Connection in an Ethernet network with DHCP server –

automatic and dynamic allocation of IP addresses (connection
with patch cable via hub or switch)

– Connection in an Ethernet network with manual IP address

assignment (peer-to-peer) – manual allocation of IP addresses
(connection with crossover cable)

Connection in a network with DHCP
(Dynamic Host Configuration Protocol)

The TH LINK is preset to network operation with a DHCP server
and in this case it is automatically assigned an IP address.
Therefore, no further configuration settings are necessary.

Note!

If you connect to Ethernet network with the
power supply already connected, the DHCP
may fail to be identified. The routine for the
DHCP identification only runs during TH
start-up.

LINK

Briefly switch off the power supply for a new
DHCP identification.

TH LINK | Trebing & Himstedt Prozeßautomation GmbH & Co. KG

21

Configuring the TH LINK in the Ethernet network

Connection in a network with manual IP address assignment

If you use the TH LINK in an Ethernet network without DHCP
server, you need the following for configuration:

– TCP/IP settings for this network
– a PC/notebook with a web browser and Adobe Flash Player
– a crossover cable between PC/notebook and TH LINK (peer-

to-peer connection)

Note!

Always notify your system administrator prior to
allocating IP addresses.
If you set an address already assigned, other
devices in the network may be deactivated and
communication may be affected.

Note!

The PC/notebook must be in the same subnet
as the TH

LINK.

The TH LINK has the following manual default IP addresses
(default settings at the time of delivery):

IP address 169.254.0.1
Subnet mask 255.255.0.0
Default gateway 0.0.0.0

–the TH LINK is integrated into the Ethernet network
–the TH LINK is energized
– the PC/notebook is in the same subnet

Procedure

Start a web browser on your PC/notebook.
– For DHCP: Enter the host name (basic setting:

THLINK_+serial number) found on the TH LINK's type label

Connecting the PROFIBUS

Connecting the PROFIBUS

The 9-pin D-Sub socket is used for connection.
– Only use standard PROFIBUS plugs and cables.
– Wire the PROFIBUS plug according to the details for pin

assignment (

– If the TH LINK is installed at the beginning or end of the

PROFIBUS cable segment, you will need a bus terminating
resistor (

see "Technical data" on page 34).

see "Bus terminating resistors" on page 30).

Warning!

Do not use branch lines for the connection.
If local conditions do not allow a direct
connection, use a repeater (connection
according to PROFIBUS norm).

1. Attach the PROFIBUS connector onto the PROFIBUS
socket on the TH

2. Secure the plug with screws.

3. Switch the switch for the bus terminating resistor on the

Troubleshooting

Troubleshooting

TH LINK is not found in the Ethernet network

– Check the power supply (LED RUN must light green).
– Check for correct connection (RJ-45, see "Connecting to

Ethernet" on page 15).

– The TH LINK is preset to network operation with a DHCP

server (IP address for the TH
server). If your network server does not support DHCP, you
need to set the IP address for the TH
(see "Connection in a network with manual IP address
assignment" on page 22).

– When a crossover cable is used between PC/notebook and

LINK, both devices must be in the same subnet.

TH

PROFIBUS network is not found

TH LINK as Passive PROFIBUS station:
– Check for proper connection (see "Connecting the

PROFIBUS" on page 28) and switch at Settings >

TH SCOPE > Measurement the baud rate on Automatic
detection.

LINK is assigned by the DHCP

LINK yourself

TH LINK as Active/Passive PROFIBUS station:
– Check the PROFIBUS parameters for the used TH LINK (see

application software, not included in the scope of delivery).
Each station has its own station address, which can only be
assigned once in the network.

Duty to monitor products

As part of our duty to monitor products, we strive to warn about dangers
we have identified which can result from the interaction of hardware and
software and product use with third-party products. Monitoring is only
possible if we receive sufficient information from our customers on the
planned application(s) and the existing hardware and software
components. As a result of the complex interactions, it is no longer
possible for us to accurately identify all dangers and to check the effect on
the overall system and in particular on our hardware and software, if the
conditions of application have changed and/or hardware or software has
been exchanged. This installation guide does not describe all technical
characteristics of the hardware and software and their variants. For more
information please contact Trebing & Himstedt Prozeßautomation GmbH
