FREQUENTLY ASKED QUESTIONS

Q: When I would like to use another ACCON-NetLink-USB compact or a
different USB port of my PC I have to install an USB driver again
although I already used an ACCON-NetLink-USB compact on this PC
before.
A: In general, all USB devices have their own serial number so they can
be identified as an already known device. If you are using two USB
units of the same type there will be two driver instances installed on
your PC, too.
The USB driver is located on the provided DELTA LOGIC
Automatisierungstechnik-DVD (<DVD-drive>\ACCON-NetLink\S7-
Treiber\) or just download it from our web site www.deltalogic.de.
Q: During the usage of an ACCON-NetLink-USB compact with an
external hub or a separate USB card unexpected errors occur.
Disconnecting and reconnecting the USB cable between ACCON-
NetLink-USB compact and hub does not work.
A: When e.g. the power supply of the hub is too weak for the ACCON-
NetLink-USB compact, some of the hubs are reporting an error to the
host system (PC).
To solve the problem with the ACCON-NetLink-USB compact use an
external power supply for this device.
Q: I get an error message when accessing the controller.
A: Check the error message.
The problem may be the setting of the PG/PC interface (e.g.
PROFIBUS instead of MPI, address already in use, etc.) or the ACCON-
NetLink-USB compact, for example, if it is not connected or the
necessary USB driver has not been installed, yet.
Q: There are no dialog settings in the Simatic Manager.
A: When you installed the ACCON-S7-NET driver for the first time you
have to add it to the PG/PC interfaces, too. Make sure that you have
administrator rights when installing the driver. After a successful
installation you have to reboot your system. Simatic Manager
Version 5.1 is minimum!
