4.3 Cabling and Equipment Required for Line B Type
4.3.1 Cables
You need a shielded twisted pair cable for your cabling (bus segments or drop
cables). Any shielded twisted pair cables available on the market can be used to
connect your adapter to a PROFIBUS network, however, bus segment cables
must contain wire for data ground and a cable braid shield. We recommend
Sprecher+Schuh cable as shown in the following table.
4.3.2 T-junction Connectors
You need t-junction connectors to connect your droplines to bus segments. You
can use any t-junctions available on the market, however, we recommend
Sprecher+Schuh connectors as shown in the following table.
4.3.3 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 must use termination blocks, any
termination blocks available on the market can be used, however, we
recommend Sprecher+Schuh termination blocks as shown in the following table.
4.3.4 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 B, refer to the
PROFIBUS Standard (DIN 19245 Parts 1 & 3, Issue 1994).

For line A or B connections, use bus segments with t-junctions and termination
blocks to form the PROFIBUS media (trunk cable). Use termination blocks to
terminate the line at each end of the trunk cable. Use drop cables to connect
devices to the network.
