Profibus employs screened twisted pair cable on the basis of the RS485
interface. The data transfer rate of the system is limited to a max. of
12MBaud.
The RS485 interface uses differential voltages. For this reason this kind of
interface is less susceptible to interference than a plain voltage or current
based interface. The network may be configured as linear or as tree
structure. Your Profibus coupler carries a 9pin socket. This socket is used
to connect the Profibus coupler to the Profibus network as a slave.
Due to the bus structure of RS485, any station may be connected or
disconnected without interruptions and a system can be commissioned in
different stages. Extensions to the system do not affect stations that have
already been commissioned. Any failures of stations or new devices are
detected automatically.
Every device on the Profibus is identified by an address. This address must
be an unique number in the bus system between 1 and 99. The address of
the VIPA Profibus coupler is set by the addressing switch located on the
front of the module.
Every VIPA Profibus slave is delivered together with a data medium. There
you can find among others all GSD files of the VIPA Profibus modules.
The assignment of the GSD-file to your slave is shown in the following
table:
Order number
GSD-file
VIPA 353-1DP00
VIPA056B.gsd
VIPA 353-1DP01(DP-V0)
VI0009AF.gsd
*
VIPA 353-1DP01(DP-V1)
VI0109AF.gsd
*)
This GSD-file is used for Profibus master that don't support DP-V1.
Please install the required files from your disc into your configuration tool.
Details on the installation of the GSD and/or type files are available from
the manual supplied with your configuration tool.
You may also download the GSD-file via the ftp-server
ftp: //ftp.vipa.de/support/profibus_gsd_files
.
After the installation of the GSD-file you will find this entry e.g. in the
hardware catalog from Siemens under:
Profibus DP>Additional field devices>I/O>VIPA_System_300V>
