1Overview
1.1 Application and function description
This document is intended as a supplement to the NETLink®
product line manuals.
Many visualization manufacturers support the TCP/IP protocol
‘RFC1006’ also known as ‘ISO on top of TCP’ to be able to com-
municate with S7-300/S7-400 systems, for example.
If this ‘RFC1006’ function is activated for example in the NET-
Link®PRO, explicit adaptations must be made to the software
products. This manual describes step by step the basic settings
of a small selection of visualization solutions for transferring
data via this communication path.
In firmware versions from 2.3 of the NETLink ® PRO family
adapters the "RFC1006" function is always active.
It is assumed that the reader is familiar with the development
environment of the software solutions mentioned in this doc-
ument, as only the points specific to the connection are de-
scribed
More extensive support with commissioning and parameteriza-
tion of the various SCADA-, HMI/OPC server systems is avail-
able directly from the manufacturers in question.
At this point is not described how a Internet teleservice via
VPN and port forwarding is implemented with a NETLink®
Ethernet gateway.
1.2 Information in the figures
Many of the figures in this document contain settings and di-
rections for use marked or highlighted in red.
Please pay attention to
the information in the
figures

2RFC 1006 Activation via the Web Interface
The examples described here are based on NETLink models
with firmware versions less than V2.3 (e.g. NETLink ® PRO).
Prior to the use with this device the RFC 1006 functionality has
to be set manually.
A detailed description is also given in the accordingly manual!
We generally recommend upgrading your NETLink®products
with the last firmware version, so you can always use the latest
features.
2.1 Requirements
The NETLink®Ethernet gateway is connected to the PC via a
network card. One of the SCADA/OPC server programs de-
scribed below is also installed on this PC. The Webinterface
function must not be deactivated. It is accessed via one of the
installed Internet browsers (for example, Mozilla Firefox, Op-
era, Konqueror, or Internet Explorer).
You do not need to install any additional drivers for the NET-
Link®.
The applications described here were performed on the Win-
dow XP operating system with service package 2 and 3.
2.2 Adapting the configuration side
As soon as the Web interface is opened by entering the rele-
vant URL ‘http://<ip address>’, the link to “Configuration” opens.
As soon as you have answered the security query, you can write
to all parameters.
From version 2.3 there is a text field: "RFC mode is always acti-
vated". In this case, you can skip this section.
The ‘RFC 1006 interface ON/OFF’ option is activated by entering
“ON” and confirming with the “OK” button (see Fig.)
In the next window, the settings are displayed again and must
be confirmed with “OK” before they are finally transferred to
the NETLink®device.
The following figure shows the configuration screen in the
NETL ink ® PRO web interface. In the current firmware
versions of other NETLink ® Ethernet variants is this manual
assignment not necessary.

-881-MPI11 and
700
-881-MPI12

Configuration menu in NETLink®PRO:
After the new parameterization data have been stored, the
NETLink®PRO is restarted to activate the new configuration.
Rebooting can take up to
15 seconds.

3Systeme Helmholz OPC-Server
V4.12.0.11527
The following steps must be performed in the described se-
quence (Version November 2017):
3.1 Configuration of the communication partner
Start the “Configuration S7-OPC Server” program module via
Start/Programs/Systeme Helmholz/S7-OPC-Server:
•Select tab card “Devices”.
•In this example, click device 0 and then select “S7-TCP/IP”
from the pull-down menu.
•Go to the tab “Connections” in the right sub window.
•Click „Change…“to create a new connection.
It opens a new connection window

•The PLC no. and Rack in this example is not relevant
•Enter the NETLink®address in the IP address field
•Enter the MPI address of the connected PLC in “Slot”
•Finally set the type of PLC you are working with.
•Close the window by clicking “OK”.
Complete your connection settings with “Apply“
Next, select the main tab “Connections”
•Click the Button “Scan”.
Enter the configured device number (possible 0 to 15). In this
example -> 0
•Confirm with “OK”
The connection to the adapter should be established and dis-
played.

11
•The CPU can be determined with “Test” (this feature is op-
tional and must not be executed in mandatory).
•The connection test was successful and can be confirmed
with “OK”.
The OPC server is now fully configured for a NETLink® to PLC
connection.
If you want to set up multiple connections within a device, the
“PLC no.” has to be unique for each connection. These num-
bers must be different.
3.2 Setting up the OPC Toolbox demo client
The following steps are provided as an example only and are
not obligatory for customer applications. They serve as a visual
check whether data exchange is taking place.
Start program module “OPC Toolbox demo client” with
Start/Programs/Systeme Helmholz/S7-OPC-Server. The various tab
cards are displayed below.
The “OPC Servers" field opens first:
Choose the CPU address
as
PLC-number to pre-
vent duplicates

•the tree structure can be open by clicking the plus sign in
front of “Local”
•open “Data Access V3” in a similar manner
•open “Helmholz S7/S5 OPC Server” similarly
•Double-click “Helmholz.OPc.S7.DA.1”
•The “group” opens in the left field.The green circle indicates
that the connection has been started.
Now switch to the “DA Browse” tab card.
•open“opcda://Helmholz.OPC.S7.DA.1/{…” in the tree structure
•A device is displayed when it has been found (in this case
“0.0”).
•On opening the device, the data access objects are searched
from the CPU and then listed.
•Transfer the selected items into the left column by double
clicking (multiple selections possible).

Now switch to the “DA Items” tab card.
•The connection quality status is displayed in the “Quality”
column
•Currently, only the permissible name range elements are dis-
played under "Value".
•Every item can be edited by selecting it and then clicking the
“Properties” button.
•The changes are adopted with “Apply” and “OK”.
