Publication 1794ĆUM057B-EN-P - November 2001
Line A cabling can support baudrates as high as 1.5M bits/s.
Cables
You need a shielded twisted pair cable for your cabling (bus
segments or drop cables). Any line A cable available on the market
can be used to connect your adapter to a PROFIBUS network.
TĆjunction Connectors
You need t-junction connectors to connect your droplines to bus
segments. You can use any t-junctions available on the market.
Termination Blocks
Termination blocks are only needed if the devices on the end of the
network do not have built-in terminating resistors. If you need
termination blocks, you can use any termination blocks available on
the market.
Bus Connector
Connect your adapter to the PROFIBUS DP network by attaching a
bus connector to the female 9 pin D-Sub connector on the front of
the module.
IMPORTANT
For detailed information on the topology and
cabling for line A, see the PROFIBUS Standard
(DIN 19245 Parts 1 & 3, Issue 1994).
