Line B cabling can support baudrates as high as 500k bits/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.

TĆjunction 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 table below.

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.

IMPORTAN

For detailed information on the topology and

cabling for line B, see the PROFIBUS Standard

(DIN 19245 Parts 1 & 3, Issue 1994).
