ACCON-NetLink-USB compact 3
2TECHNICAL DESCRIPTION
ACCON-NetLink-USB compact is the compact communication and
programming adaptor between PC and S7 controllers. The electronics of
the ACCON-NetLink-USB compact is placed in the box of a PROFIBUS
connector what makes the adaptor very small and handy.
As all-rounder, the ACCON-NetLink-USB compact can be connected to
the PLC via MPI, PROFIBUS and PPI. The ACCON-NetLink-USB compact
independently detects the current bus settings of the PLC.
The communication of the ACCON-NetLink-USB compact and the PC is
effected via USB. The device supports the parametrization of DP-Slaves
via DP-V1 (class 2). A driver for SIMATIC applications (ACCON-S7-NET) is
included. The ACCON-NetLink-USB compact gets its power supply via
the USB cable.
Features:
•Automatic bus profile detection
•Full PROFIBUS speed 12 Mbps
•USB 2.0 up to 480 Mbps (Highspeed)
•Extended diagnostics options
•MPI, PROFIBUS and PPI is supported
•Supports slave parametrization via DP-V1 (class 2)
•Supports all established SIMATIC Engineering Tools
•Power supply via USB
•Plug with PG socket
•Can be used up to 60 °C

5REQUIREMENTS FOR OPERATING
Hardware requirements
Siemens S7-200-, S7-300 and S7-400 automation devices or compatible
to S7. The used PCs must have a working USB interface. You can also
use standard USB cards which support both Highspeed 480 Mbps and
Fullspeed 12 Mbps. But to achieve a good performance you should use
USB 2.0 interfaces.
Software requirements
To use the ACCON-S7-NET drivers you need a PC including Windows XP,
2003R2, 7, 2008R2, 8.1, 2012R2, 10. On this PC the SIMATIC Device
Drivers (PG/PC-Interface) have to be installed. The SIMATIC Device
Drivers will be installed with e. g. STEP 7, STEP 7 lite or STEP 7-
Micro/Win. By installing ACCON-S7-NET more interfaces will be added
to the PG/PC-Interface.
Assembly
Installation and assembly have to be carried out according to VDE 0100
/ IEC 364. As the ACCON-NetLink-USB compact is an IP30 module it has
to be built into a switchboard.
For secure operating please keep the maximum environmental
temperature of 60 °C in mind.

6COMMISSIONING
Connection to the PC
Put one end of the USB cable into the USB socket of your ACCON-
NetLink-USB compact and the other end into a USB port of your PC.
Connection to the automation device
Connect the 9-pin SUB-D plug to the MPI or PROFIBUS interface of your
S7 controller.
Installation of the USB driver
When connecting an ACCON-NetLink-USB compact to the PC for the
first time, the operating system tries to install a suitable device driver.
This could take a while and continues as follows:
For the installation under Windows you need to be logged in as
administrator!
The operating system starts an installation wizard.
1. Lay in the delivered DELTA LOGIC Automatisierungstechnik-DVD
and select the folder:
S7-Adapter\ACCON-NetLink\USBDriver
Then click on »Next«.
2. Now the driver search starts.
3. If found, the installation can be started with a click on »Next«.
4. After a successful installation click on »Finish« to complete the
setup.
The ACCON-NetLink-USB compact has been installed successfully and
can be used now. If there are several ACCON-NetLink-USB compact
devices available it is recommendable to copy the USB drivers to your
hard disk. As for every ACCON-NetLink-USB compact a single driver
entity is installed. Therefore the driver data is needed every time when
installing an ACCON-NetLink-USB compact. Remember that you cannot
use more than one ACCON-NetLink-USB compact on a single PC,
simultaneously.

Latest driver and firmware versions can be found on our web site at
www.deltalogic.de in the section »Downloads«.
Installation Software
The driver ACCON-S7-NET can be installed by executing the file
»SetupAcconS7Net.exe« from the DELTA LOGIC
Automatisierungstechnik-DVD (<DVD-drive>\S7-Adapter).
Set PG/PC Interface
1. Open the SIMATIC PG/PC Interface.
The following points have to be in the dialog »Set PG/PC Interface«:
- ACCON-S7-NET NLUSB(MPI)
- ACCON-S7-NET NLUSB(PPI)
- ACCON-S7-NET NLUSB(PROFIBUS)
Figure 2: Set PG/PC Interface

7BUS SETTINGS
The ACCON-NetLink-USB compact can be used with three different bus
systems: PPI, MPI and PROFIBUS.
Configuration example: MPI
The MPI configuration contains station-related settings and net-related
settings.
The most important setting of the bus configuration is the station
address. This is the address of the ACCON-NetLink-USB compact when
going online on the bus. The station address can be in the range from
»0« to »126« as long as the chosen address is smaller or equal as the
highest station address. This address is allowed only once.
The timeout can be set in the station-related settings of the ACCON-S7-
NET driver. If there is no response to a driver enquiry within the set
timeout, a communication error is sent to the SIMATIC application. The
decrease of the timeout has no effect on the performance. 60 000 ms is
the recommended timeout value.
In the net-related settings you have to adjust the transmission rate as
well as the HSA of the automation system to which should
communicated with.
Figure 3: Automatic bus profile detection activated

ACCON-NetLink-USB compact 11
To ease the configuration it is possible to activate the function
»Automatic reconnaissance of the net-related parameters activated«.
Thus the ACCON-NetLink-USB compact gets the bus parameters
independently. So the ACCON-NetLink-USB compact can be used with
different automation systems without changing the bus settings.
The automatic reconnaissance of the net-related parameters cannot be
used when the function »Cyclic distribution of the bus parameters« is
not activated respectively not supported in the used PLC, e. g.:
- using S7-200
- older Siemens S7 CPUs
- if the ACCON-NetLink-USB compact is the only master at the bus
When using the autobaud function the initialization lasts a bit longer
because the online parameters have to be determined. It is possible
that the autobaud function does not work correctly at slower
transmission rates (e. g. 19.2 Kbps) or global data communication.

ACCON-NetLink-USB compact 12
PROFIBUS communication
The PROFIBUS configuration is the same as the MPI configuration. Only
the net-related parameters are wider. With PROFIBUS the additional
settings for bus profile and bus parameters are available:
Figure 4: Automatic bus profile detection deactivated
Profile:
Under PROFIBUS there are the profiles »DP«, »Standard« and »User-
defined«. You have to select the profile which is already used in the
automation system.
Bus parameters:
Unlike to MPI the bus parameters under PROFIBUS are not constant
and change in relation to the number and type of the used PROFIBUS
stations.
You should always use the PROFIBUS parameters which are set in the
actual automation system (look for the STEP7 project).

ACCON-NetLink-USB compact 13
Figure 5: Bus parameters
To sidestep these partly complex steps you can use the function
»Automatic reconnaissance of the net-related parameters« under
PROFIBUS.
To get the » Automatic reconnaissance of the net-related parameters«
to work, you have to activate the »Cyclic distribution of the bus
parameters« in the hardware parametrization of the interface.

ACCON-NetLink-USB compact 14
The following screenshot shows the switch for the »Cyclic distribution
of the bus parameters«. It is located in the hardware configuration of
any PROFIBUS interface:
Figure 6: Cyclic distribution of the bus parameters

ACCON-NetLink-USB compact 15
PPI communication
The PPI configuration is the same as the MPI configuration, but the
automatic reconnaissance of the net-related parameters is not possible
with S7-200 controllers.
Figure 7: Bus settings PPI
For more information of the use of Advanced PPI look for the help of
the S7-200 programming software.
To communicate with a EM 277 you have to activate Advanced PPI

Diagnostics function:
This function can be found via Set PG/PC-Interface > Diagnostics. There
you can execute hardware diagnostics of the module. The following
values can be determined:
1. List of all reachable stations at the bus.
2. Bus parameters which the ACCON-NetLink-USB compact uses on
the bus.
Figure 9: Diagnostics function
Click on the button »Read« to determine the values.
Notes about the stations:
Address: Bus address of the station
Station type: There are active (Master) and passive (Slave)
stations
MLFB number: The order number of the station is only shown if
the option »Read MLFB number« is activated.
The used ACCON-NetLink-USB compact is shown
as »Station address«.
Notes about the bus parameters:

If there is no automatic reconnaissance of the net-related parameters,
the manually set bus parameters of the ACCON-NetLink-USB compact
are shown.
