3 System Overview

3.1 Application and function description

The NETLink PRO ETH is a gateway between a TCP network and a PPI,
MPI or PROFIBUS.

Two protocols are available at the TCP end for exchange of useful data with
the automation system (multi protocol mode):

• One is a proprietary protocol that is used to connect to the proprietary
NETLink PRO driver

• The other is the S7-TCP/IP protocol often used by visualization
system manufacturers which is known as ‘RFC1006’ or ‘ISO on top
of TCP’.

Up to seven (6+1) TCP connections (10 Mbps or 100 Mbps) and up to
twelve MPI/PROFIBUS connections (9.6 kbps to 12 Mbps) can be used
simultaneously.

Please note that up six TCP links per TCP protocol but no more than seven
TCP links in total can be opened in multi protocol mode.
This means that at least one spare link always remains that can be used by
the other protocol.

On both the TCP and the field bus sides, the baudrate used can be
determined automatically (autonegotiation or autobaud)

The NETLink PRO ETH can draw the necessary power supply either from
the bus interface of the programmable controller or via an external power
supply.

The connecting cable used to link the NETLink PRO ETH with the
programmable controller is 1.2 meters long and active. Because it is active,
no spur lines are required that could interfere with the bus.

The use of NETLink PRO driver makes it possible to use NETLink PRO
ETH as the following at the PC end

• Programming adapter,

• Teleservice unit or

• Operator control and monitoring unit

The RFC1006 interface also enables you to use third-party software that
supports this protocol for S7-300 and S7-400 systems.

In both cases the NETLink PRO ETH is connected to the PC via a switch or
hub.

If the NETLink PRO is connected directly to a PC, a crossover adapter must
be interposed between the PC and the NETLink PRO ETH (for accessories,
see section 3.5).

NETLink PRO ETH 5

3.2 Connections

The NETLink PRO ETH has the following connections:

• RJ45 socket for connecting the unit to a commercial type switch or
hub using a standard CAT5 TCP cable (straight).
If the NETLink PRO ETH is to be operated directly on a PC, mostly
a cross adapter (for accessories, see Section 3.5)or a CAT5 TCP
cable (cross) must be used.

• Power supply socket for 24 V DC power supply.
This power supply option can be used, if the programmable controller
used does not provide any or only insufficient power on the bus
connector.

• Bus connector with programming unit socket, switchable terminating
resistor, and 1.2 m connecting cable.
The programming unit socket of the bus connector allows further bus
nodes to be plugged in.
The terminating resistor must be connected (ON) if the NETLink
PRO ETH is at the beginning or end of a bus segment. If this is not
the case, the switch position must be OFF.
The 1.2 m connecting cable is an ‘active cable’. This means there is
no spur line, which avoids interferences with high baud rates.

3.3 LED displays

The NETLink PRO ETH has five LEDs, including two two-color LEDs, to
indicate its operating status.

4 Installation of the driver software

With installation of the NETLink PRO driver for the NETLink PRO ETH, it
is easy to access controllers with a PPI, MPI or PROFIBUS interface from
the PC via TCP/IP.

4.1 Introduction

The NETLink PRO driver is inserted in the PG/PC interface of an existing
Simatic application and can then be used from most Simatic engineering
tools (STEP7, ProTool, WinCC, etc.).

Access is possible to any controllers of the Simatic S7-200, S7-300 or S7­400 series. The NETLink PRO ETH communication adapter is required to
connect a Simatic S7-200, S7-300 or S7-400 controller with the Ethernet
network.

4.2 System requirements

A PC with a 32-bit Windows operating system is required to operate the
NETLink PRO driver at the PU end. The Windows 2000 and Windows XP
operating systems can be used.

A further requirement is the existence of a Simatic engineering tool such as
STEP7, Version 5.1 and higher or STEP7 Micro/Win, version 4.0 and
higher, which ensures that the PG/PC interface is installed on the computer.

Installation under Windows 98/ME/NT is possible but is not supported by
our technical support team. Please pay attention to the requirements of the
SIMATIC package used.

A functioning network link using TCP/IP must have been set up on the PCs
that are used. The network configuration of the PC must be known. You can
use normal commercial type network cards. To maximize performance, 100
Mbps network cards and switches should be used in the local area network.
Of course, you can also use 10 Mbps network cards and hubs but that would
slow down status operation.

4.3 Running the installation setup

After the installation CD is inserted, a menu will start automatically, which
gives the choice to install the NETLink PRO driver.

If setup does not start automatically, the setup file ‚SetupNETLinkPRO.exe’
can be launched manually in directory ‘CD drive:NETLinkPRO\’.

If necessary, you can download the latest NETLink PRO driver from our
homepage (http://www.softing.com).

Please note that for installation you have to log on as an administrator under
the 32-bit Windows operating systems because the setup program has to
make entries in the Windows registry.

4.3.1 Adding the interface to the PG/PC interface

After initial installation, the new interface parameter set ‘NETLink PRO’ has
to be set up. Administrator rights are necessary for this.

After you have started ‘Set PG/PC Interface’ in the Control Panel, click the
‘Select…’ button there.

Administration rights are

required for installation.

NETLink PRO ETH 9

The ‘Installing/Uninstalling Interfaces’ dialog box now appears.

After you have selected the entry ‘NETLink PRO ETH’ from the left-hand
list, click the ‘Install’ button.

The following query then appears.

If you answer ‘Yes’ to this query, the NETLink PRO ETH is immediately
set as the current access path. If you respond ‘No’, the previous access path
remains set and the NETLink PRO ETH is put in the selection list where you
can select it later.

10 NETLink PRO ETH

Now you have answered the query, ‘NETLink PRO ETH’ will also appear in
the right-hand list with the interfaces already installed.

The access path in the ‘Set PG/PC Interface’ dialog box is set when this
window is closed.

4.3.2 Selecting the required interface parameterization

The selection list for the interface parameter sets now contains an additional
three items for the NETLink PRO ETH.

All relevant settings of the NETLink PRO driver must be made in the
‘Properties…’ field. With the button ‘Diagnostics...’ it is possible to show
the nodes connected to the bus and the parameters the bus is working with.
These fields are explained in Section 5.

NETLink PRO ETH 11

5 Configuration via the NETLink PRO driver

Once a NETLink PRO ETH has been selected in the ‘Set PG/PC Interface’
window, it is possible to specify this access path more precisely with the
‘Properties…’ button.

With the functionality behind the button ‘Diagnostics...’, it is possible to
read the bus configuration and scan connected nodes.

The properties of the access path NETLink PRO ETH(xyz) are divided into
three subareas as follows:

• Local connection (TCP configuration)
Here, you set the IP address via which the required connection with
the programmable controller will be established.
The NETLink PRO ETH hardware can also be parameterized in this
window.

• Bus settings
Here it is possible to state the bus configuration (e.g. station address)
with which the NETLink PRO ETH will enter the bus system.

• Options
Here it is possible to change the language of the NETLink PRO
driver and to read out the version information of the driver.

Two functionalities are implemented for diagnostics at the connected bus:

• Bus members
A list of all active and passive nodes connected to the bus will be
displayed. By request the order numbers (MLFBs) will be displayed
also if this functionality is available by the nodes.

• Bus parameters
If possible, a list of all available bus parameters will be displayed

5.1 Properties

5.1.1 Local connection (TCP parameterization)

There are three basic ways of parameterizing NETLink PRO ETH at the
TCP end:

• Parameterization via ‘Set PG/PC interface
Existing stations can be reparameterized using the ‘Change’ button

• Parameterization via the parameterization tool ‚NETLink PRO
Configuration’ (see section 6).

• Parameterization via the web interface of the NETLink PRO ETH
(see section 7.3)

If the NETLink PRO ETH is configured via the NETLink PRO driver, the
following points must be considered:

• If the NETLink PRO ETH is active on the bus when
reparameterization is required (e.g. a variable table or block is being
viewed), reparameterization is not performed because the ensuing
reset would interrupt the NETLink PRO ETH link.

• The NETLink PRO ETH is protected against unauthorized
reparameterization via a password (default password: “admin”).
If an attempt is made to save a parameter set with an incorrect
password, the following message is displayed:

The password query must be
answered correctly and
confirmed with OK.
