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 and with the IM 306 DP slave between 2
and 125.
At the IM 306 DP slave the Profibus address may be set by the address
switch located at the front side of the module. This address must be
assigned during hardware configuration of the master system in the
properties dialog of the slave system.
For the IM 306 DP slave there are GSD files available from VIPA. These
may be downloaded from the "Service" area of www.vipa.de.
The IM 306 DP slave may be configured as DP-V0 or as DP-V1 slave.
Each slave type has its own GSD file.
The assignment of the slave type is shown in the following table:
Slave type GSD file
DP-V0 VI100BB4.GSD
DP-V1 VI110BB4.GSD
Please install the required files in your configuration tool. Details on the
installation of the GSD files are available from the manual supplied with
your configuration tool.
After the installation of the GSD file the IM 306 DP slave may be found in
the hardware catalog from Siemens at:
