PROFIBUS coupler BK3xx0 in the PROFIBUS DP
32 BK3xxx/LC3100
You should also note that the terminating resistor requires a 5 V power
supply for optimal operation. This means that if the plug is removed from
the bus coupler, or the power supply of the bus coupler fails, the level at
the terminating resistor will vary, which may affect the data transfer.
Configuring the master
As explained above, the Profibus coupler sets up a data area containing
the input and output bytes. The assignments between the channels of the
bus terminals and the bits and bytes of the process image are carried out
by the bus coupler.
The Profibus master exchanges a coherent input and output data block
with each Profibus coupler. The correlation between the bytes in this data
block and the addresses of the process image is carried out by the master.
In the case of the IM308-C SPS master, this parametrization is supported
by the software COMWIN, and for the IM308-B by the software
COMET200. For other masters you should use the corresponding tools
provided by the manufacturer (see also the chapters Device master file
and Type file).

Quick start
When the coupler is started up, all the terminals are written into the process
image. The coupler then proceeds in accordance with the following rules:
first all the terminals with byte-oriented operation, then all the bit-oriented
terminals.
