Connect Your Adapter to the PROFIBUS DP Network 73
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.
Cabling and Equipment
Required for Line B Type Line B cabling can support baudrates as high as 500 kbits/s.
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 table below.
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
Table Cable Types and Descriptions on
page 74 .
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 to use termination blocks, any
termination blocks available on the market can be used, however, we recommend
Sprecher+Schuh termination blocks as shown in the table below.
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.
